A Connecticut residential lease agreement is the written contract governed by Connecticut General Statutes chapter 830, at 47a-1 and following, together with the security-deposit section at 47a-21 and the summary-process sections at 47a-23 and following. Connecticut has drifted a long way from the uniform act it started with, and the drift accelerated between 2023 and 2025. The security deposit is capped at two months’ rent — but only one month’s rent for a tenant sixty-two or older — and it must sit in an escrow account at a named financial institution while earning interest the landlord pays out every year. Entry needs “reasonable” notice and no fixed number of hours. Ending a month-to-month tenancy takes a three-day notice to quit, not the thirty days most templates recite, while a rent increase now takes forty-five days. And from April 1, 2026 a written Connecticut lease is not compliant at all unless a Department of Housing summary form sits in front of it as page one.

The Connecticut duty almost no template carries: Conn. Gen. Stat. 47a-21(i) requires the landlord to pay interest on the security deposit, at not less than the deposit index the Banking Commissioner sets each year under 36a-26 and publishes by December fifteenth of the prior year. The interest is paid or credited on every anniversary of the tenancy, and 47a-4(a)(4) makes a lease clause waiving it unenforceable.

Four Connecticut Rules That Catch Landlords Out

First, the deposit cap has two tiers. Conn. Gen. Stat. 47a-21(b) allows two months’ rent, but only one month’s rent where the tenant is sixty-two or older — and a landlord already holding two months from a tenant who turns sixty-two must hand the excess back on request. Second, the deposit is not the landlord’s money and cannot sit in the landlord’s account. Under 47a-21(h) it goes immediately into an escrow account at a financial institution, and the tenant must be told the amount held and the name and address of that bank within thirty days. Third, it earns interest, every year, whether or not anyone asks. Fourth, the notice periods are not the ones templates recite: three days to quit, nine days of grace on rent, fifteen days to cure another breach, twenty-one days to return the deposit, and forty-five days before a rent increase.

How to Fill Out This Connecticut Lease Agreement

The Seven-Step Connecticut Sequence

1. Name the landlord, the manager and the agent for service

Conn. Gen. Stat. 47a-6 requires written notice, on or before the tenancy begins, of the name and address of the person authorized to manage the premises and of the person authorized to receive all notices, demands and service of process — kept current thereafter. Skip it and 47a-6(b) deems whoever signed for the landlord to be the landlord’s agent for service and for performing the landlord’s repair duties.

2. Describe the premises and count the units

Enter the address, county and property type. Property type decides how maintenance may be reallocated under 47a-7, and the unit count matters: at five or more dwelling units the protected-tenant regime in 47a-23c attaches, with good-cause eviction, fair-and-equitable rent increases and a written rights notice on every renewal.

3. State the all-in rent and the due day

Since 2025, Conn. Gen. Stat. 47a-7d requires every fee a tenant must pay periodically to be prorated into the offered rent, so the figure in the lease should be the one the tenant actually pays each month. The same section applies every payment to rent first and to other charges only afterwards.

4. Set the deposit against the right cap

Two months’ rent, or one month where any tenant is sixty-two or older. Enter the first month’s rent and any key deposit separately — 47a-21(a) excludes both from the definition of a security deposit, so neither counts against the cap and neither carries the escrow and interest duties.

5. Name the escrow bank

The form asks for the financial institution and its address because 47a-21(h)(4)(A) requires the tenant to be told both, in writing, within thirty days. Putting it in the lease itself is the simplest way to be sure the notice was actually given.

6. Check the disclosures Connecticut requires

Eight state disclosures plus the federal lead-paint one, and three of the eight were created between 2023 and 2025. The fire sprinkler notice has to appear in the lease in twelve-point boldface, which is why it is generated into the document rather than attached.

7. Generate, sign, and put the summary form in front

Download the multi-page PDF and sign. No witnesses and no notary are required. But on and after April 1, 2026, 47a-7d makes a completed Department of Housing standardized rental terms summary form the mandatory first page of the written agreement, so print it and put it in front of this one. Download the official fillable form direct from the Department of Housing: standardized rental terms summary form (PDF, bilingual English/Spanish), listed on the DOH mandatory landlord-tenant forms page. The requirement itself is set out in DOH Notice OPRHS 2026-005 (27 March 2026). Complete DOH’s own file rather than recreating it – subsection (d) requires the form published pursuant to subsection (c).

Complete the fields below to generate a Connecticut residential lease agreement as a signable multi-page PDF. Every field you fill is written into the document, including the utility allocations, the escrow bank and each disclosure you check, and the generated lease cites the controlling Connecticut section at each point. Before handing over keys, run proper tenant screening — and note that Connecticut regulates the screening fee itself. Pair the signed lease with a Connecticut move-in / move-out checklist, because 47a-7c makes the pre-occupancy walk-through the document that decides what may later be deducted from the deposit.

4. Rent

Connecticut requires the advertised rent to be all-in from 2026 — every fee the tenant must pay periodically is prorated into it (47a-7d). Enter the total periodic rent, not a base figure with mandatory add-ons kept out of view.

5. Security Deposit, Escrow & Interest

Connecticut caps the deposit at two months’ rent, or one month’s rent where the tenant is sixty-two or older (47a-21(b)). The whole deposit goes into an escrow account at a financial institution, and the tenant must be told the amount held and the name and address of that bank within thirty days (47a-21(h)). Connecticut also requires interest on the deposit, and a lease clause waiving it is unenforceable (47a-4(a)(4)).

6. Utilities & Services

Assign each utility. Every selection below is written into the generated lease. Note that where heat or utilities is included in the rent, a surcharge clause is unenforceable under 47a-4(a)(10).

7. Connecticut Disclosures

Connecticut requires eight state disclosures, and three of them were created between 2023 and 2025. Lead paint is federal. Leave a box unchecked only where the requirement genuinely does not apply to this property.

8. Other Provisions

Connecticut’s attorney-fee rule is a ceiling, not a ban. 47a-4(a)(7) voids a clause making the tenant pay the landlord’s fees above fifteen per cent of a money judgment, and 42-150bb awards a fee to the tenant as a matter of law where the tenant wins. The option below generates only the capped, reciprocal version.

What Types of Connecticut Lease Agreement Are There?

Connecticut recognizes the standard range of residential arrangements. A fixed-term lease runs for a stated period and expires on its own terms. A periodic tenancy renews each period until one side ends it — and Conn. Gen. Stat. 47a-3b supplies the default: where the rental agreement fixes no definite term the tenancy is month to month, and where the tenant pays weekly rent it is week to week. A room or roommate agreement covers a tenant renting one room; the statute even has a word for the arrangement, defining a roomer at 47a-1 as someone whose unit lacks a refrigerator, stove, kitchen sink, toilet and shower or bathtub, one or more of which are shared. A sublease passes the tenant’s interest to a subtenant, and note that 47a-21 expressly treats a subletting tenant as a landlord for deposit purposes.

Several categories fall outside this form. A commercial lease is not governed by chapter 830. And Conn. Gen. Stat. 47a-2 exempts a longer list than most states: residence at an institution incidental to detention or to medical, geriatric, educational, counselling or religious service; occupancy under a contract of sale; occupancy by a member of a fraternal or social organization in its own structure; transient occupancy in a hotel, motel or similar lodging; occupancy by a condominium unit owner; and occupancy by a personal care assistant housed as a condition of employment. The transient test is unusually precise: under 47a-2(c) occupancy of under thirty days is transient unless the room is the occupant’s primary residence from the start, and occupancy of thirty days or more is not transient unless the room is not the primary residence and the stay runs under ninety days.

One drafting note that matters more in Connecticut than elsewhere. Nothing requires a residential lease to be notarized or witnessed. But 47a-3d provides that holding over is not evidence of any agreement for a further lease, and that a parol lease reserving a monthly rent whose termination date is not agreed is a lease for one month only. An unwritten arrangement in Connecticut is therefore not a long tenancy the parties forgot to paper — it is legally a series of one-month tenancies.

How Much Can a Connecticut Landlord Charge for a Security Deposit?

Two months’ rent — or one month’s rent if the tenant is sixty-two or older. Conn. Gen. Stat. 47a-21(b)(1) caps the deposit at two months’ rent for a tenant under sixty-two. Section 47a-21(b)(2) caps it at one month’s rent for a tenant sixty-two or older, and adds a rule most summaries miss entirely: a landlord who has already received more than one month’s rent from a tenant who becomes sixty-two during the tenancy shall return the excess on that tenant’s request.

What counts is as important as how much. Under 47a-21(a) a “security deposit” means any advance rental payment, except an advance payment for the first month’s rent and except a deposit for a key or any special equipment. So the customary first-month-plus-deposit arrangement does not breach the two-month cap, because the first month’s rent is not deposit money at all. It also means the first month’s rent does not carry the escrow duty or the interest duty — which is exactly why the form above keeps the three figures in separate fields.

The deposit also never becomes the landlord’s money. Section 47a-21(c) provides that it remains the property of the tenant, in which the landlord holds only a security interest, and that it is exempt from attachment and execution by the landlord’s creditors and is not part of the landlord’s estate in any legal proceeding. Where the building is sold, the transfer automatically assigns the landlord’s security interest in every tenant’s deposit to the buyer. The deeper treatment lives in our Connecticut security deposit laws guide.

Where Must a Connecticut Security Deposit Be Held?

In an escrow account at a financial institution, immediately. Conn. Gen. Stat. 47a-21(h)(1) requires each landlord to deposit the entire amount of every security deposit received into one or more escrow accounts established or maintained at a financial institution for the benefit of each tenant, to hold that account as escrow agent, and not to withdraw from it except for a reason listed in 47a-21(h)(2). Those reasons are narrow: paying the deposit and interest out at the end, paying interest during the tenancy, transferring deposits on a sale, retaining bank interest above what the tenant is owed, retaining what the tenant genuinely owes for damage after termination, returning money to the tenant during the tenancy, or moving the funds to another escrow account.

Then comes the disclosure that almost no lease template carries. Under 47a-21(h)(4)(A), within thirty days of receiving the deposit — or of moving it to another institution or account — the landlord must give the tenant written notice of the amount held for that tenant’s benefit and the name and address of the financial institution holding it. Under 47a-21(h)(4)(B), if the Banking Commissioner asks in writing for information about a tenant’s deposit, including the institution and the account number, the landlord has seven days to answer.

That reference to the Banking Commissioner is not decorative. Connecticut is unusual in putting a banking regulator, rather than a housing agency or the courts alone, behind its deposit rules. Under 47a-21(j) the commissioner may receive and investigate complaints about the cap, the return, the escrow duty and the interest duty, may subject a landlord to the department’s investigative powers, and may order a landlord to cease and desist and to comply. The commissioner’s jurisdiction stops at two points: a failure to pay the annual interest, and a refusal to return the deposit that rests on the landlord’s good-faith claim of damages — which the statute defines as a claim for actual damages of which written notice was given to the tenant in the itemized statement.

Does a Connecticut Landlord Have to Pay Interest on the Deposit?

Yes — and this is the Connecticut duty imported templates never carry. Conn. Gen. Stat. 47a-21(i) requires the landlord to pay interest on each security deposit at a rate of not less than the deposit index. Only student housing owned or controlled by an educational institution is carved out; mobile manufactured home owners and park operators are carved in.

The rate is not fixed in the lease and it is not fixed in the statute. Conn. Gen. Stat. 36a-26 tells you where to find it: “The Banking Commissioner shall determine the deposit index for each calendar year and publish such deposit index in the Department of Banking’s news bulletin and on the department’s Internet web site not later than December fifteenth of the prior year.” The index itself is the average of the national rates for savings deposits and money market deposits for the last week in November of the prior year, as the Federal Deposit Insurance Corporation publishes them under 12 C.F.R. 337.6. So the rate changes every January, and the only correct place to read it is the Department of Banking’s own deposit-index page. For calendar year 2026 the commissioner set it at 0.49 per cent; that figure is verified as of this page’s revision date and should be re-checked each year rather than assumed.

The mechanics are what landlords get wrong. Interest is paid to the tenant, or credited toward the next rent payment at the landlord’s election, on the anniversary date of the tenancy and annually thereafter — not held back and settled at move-out. Where the tenancy ends early, or the landlord returns the deposit early, the accrued interest is due within twenty-one days. No interest accrues for any month in which the tenant was delinquent more than ten days in paying monthly rent, unless the landlord imposed a late charge for that delinquency — a genuine trade-off, since charging the late fee preserves the tenant’s interest for that month. And the landlord may not increase the rent because of the duty to pay it.

Two more points close the loop. Conn. Gen. Stat. 47a-4(a)(4) makes a lease clause under which the tenant waives the right to that interest unenforceable, so the duty cannot be drafted away. And 47a-21(k)(3) makes a knowing and wilful failure to pay interest when due a finable offence in its own right.

How Long Does a Connecticut Landlord Have to Return the Deposit?

The later of twenty-one days after termination, or fifteen days after written notice of the forwarding address. Conn. Gen. Stat. 47a-21(d)(2) sets a two-limbed deadline that most summaries compress into a single number. The tenant may, on termination, notify the landlord in writing of a forwarding address. The landlord then has until 21 days after termination of the tenancy or fifteen days after receiving that written notice, whichever is later, to deliver to the tenant at that address either the full deposit plus accrued interest, or the balance plus accrued interest together with a written statement itemizing the nature and amount of each deduction.

The penalty is one of the sharpest in the country. A landlord who violates that subsection is liable for twice the amount of the security deposit — not twice the wrongly withheld portion, twice the deposit. There is a narrower rule for the narrower failure: where the only violation is failing to deliver the accrued interest, the landlord is liable for ten dollars or twice the accrued interest, whichever is greater. Section 47a-21(k) then adds criminal fines for a knowing and wilful failure to pay the deposit, for an escrow violation, and for an interest violation.

Practical consequence for both sides: the forwarding-address notice is worth putting in writing and worth keeping proof of, because it is what starts the fifteen-day limb running, and a tenant who never gives one leaves only the twenty-one-day limb to argue about. Build the itemization with our Connecticut security deposit itemization form and send the balance with a Connecticut security deposit return letter.

How Much Notice Must a Connecticut Landlord Give to Enter?

Reasonable notice — and Connecticut deliberately sets no number. Conn. Gen. Stat. 47a-16(c) requires the landlord to give the tenant “reasonable written or oral notice of his intent to enter” and to enter “only at reasonable times, except in case of emergency”, and in the same breath forbids the landlord to abuse the right of entry or use it to harass the tenant. There is no twenty-four-hour rule and no forty-eight-hour rule anywhere in the section. A lease that recites one for Connecticut has imported it from somewhere else.

Two things follow. What is reasonable depends on the purpose and the circumstances — a scheduled annual inspection and a plumber chasing a leak are not the same request — and oral notice genuinely suffices, though written notice is what either side can later prove. Section 47a-16(a) lists the permitted purposes the tenant may not unreasonably refuse: inspection, necessary or agreed repairs, alterations or improvements, necessary or agreed services, and showings to prospective or actual purchasers, mortgagees, tenants, workmen or contractors.

Section 47a-16(d) then closes the door on everything else. The landlord may not enter without the tenant’s consent except in an emergency, as 47a-16a permits, under a court order, or where the tenant has abandoned or surrendered the premises. Section 47a-16a is the extended-absence rule: the tenant must notify the landlord of an anticipated prolonged absence, and the landlord may then enter at reasonable times during it for the listed purposes.

Connecticut compensates for the absence of a number with an unusually concrete remedy. Under 47a-18a, where the landlord makes a prohibited entry, or makes repeated demands for entry that are lawful in themselves but have the effect of unreasonably harassing the tenant, the tenant may recover actual damages not less than an amount equal to one month’s rent plus reasonable attorney’s fees, and may obtain an injunction or terminate the lease. The floor is the point: the tenant does not have to prove a loss. The mirror provision, 47a-18, gives the landlord a declaratory judgment or injunction, actual damages and attorney’s fees where the tenant refuses lawful entry. A dated Connecticut notice to enter is how a landlord shows the notice was reasonable; see Connecticut landlord entry laws for the full picture.

What Is the Grace Period and the Late-Fee Cap in Connecticut?

Nine days of grace, and a late fee capped at the lesser of five dollars a day up to fifty dollars or five per cent of the rent. Conn. Gen. Stat. 47a-15a(a) provides that where rent is unpaid when due and the tenant fails to pay within nine days — or within four days on a one-week tenancy — the landlord may terminate under the summary-process sections. Those periods are the statutory “grace period”, and since January 1, 2026 they are extended a further five days where the landlord’s own online rental payment system prevents payment of rent when due, for the week or month in which the system failed.

The fee ceiling arrived in 2023 and is tighter than most landlords expect. Under 47a-15a(b) a late charge may be assessed only where the lease contains a valid written agreement to pay one, only on a payment made after the grace period, and may not exceed the lesser of five dollars per day up to a maximum of fifty dollars, or five per cent of the delinquent rent payment. Where the rent is paid in whole or in part by a governmental or charitable entity, the five per cent is measured against the tenant’s share. And the landlord may not assess more than one late charge on a delinquent payment, regardless of how long the rent stays unpaid — so a per-day charge stops accruing once the ceiling is hit and cannot be re-imposed the following month for the same arrears.

The prohibited-terms section backs both rules up. Section 47a-4(a)(8) makes unenforceable a clause under which the tenant agrees to pay a late charge before the grace period expires, and equally a clause offering reduced rent for paying early — Connecticut treats the discount and the penalty as the same thing wearing different hats. Section 47a-4(a)(9) makes unenforceable a clause charging more than 47a-15a allows. Section 47a-19 adds a trap on the other side: accepting rent with knowledge that it is overdue waives the right to terminate for that late payment. See Connecticut late fee laws, and serve nonpayment with our Connecticut nine-day notice to pay rent or quit.

How Much Notice Does a Connecticut Rent Increase Need?

Forty-five days — a rule that did not exist before October 2024. Conn. Gen. Stat. 47a-4e provides that no rent increase for a dwelling unit is effective unless the landlord has given the tenant written notice of the proposed increase not less than forty-five days before the day it is proposed to take effect. For a lease with a term of one month or less, the notice period equals a full term of that lease.

Three details are doing real work. The tenant’s failure to respond is not agreement to the increase, so silence cannot be treated as acceptance. The section does not allow a landlord to raise the rent during the term of an existing rental agreement — it governs the notice for an increase that is otherwise permitted, not a new power to impose one. And it does not displace any federal notice requirement for subsidized housing.

Where the tenant is protected under 47a-23c, a further limit applies: the rent may be increased only so far as the increase is fair and equitable judged against the criteria in 7-148c, and the tenant may take it to the local fair rent commission or, where none exists, to the Superior Court. Conn. Gen. Stat. 7-148b, as amended by Nov. Sp. Sess. Public Act 25-1 effective January 1, 2026, requires every Connecticut municipality with a population of fifteen thousand or more to create a fair rent commission, or join a joint or regional one, by ordinance on or before January 1, 2028; the earlier threshold was twenty-five thousand with a July 1, 2023 deadline, so most Connecticut renters already have one locally and more municipalities are being swept in. Our Connecticut rent increase laws guide covers the mechanics, and the Connecticut rent increase notice generates the document.

Which Fees Can a Connecticut Landlord Charge Before the Tenancy?

Almost none. Conn. Gen. Stat. 47a-4d, added in 2023, is one of the strictest pre-tenancy fee rules in the country. No landlord may demand from a prospective tenant any payment, fee or charge for the processing, review or acceptance of a rental application, or demand any other payment, fee or charge before or at the beginning of the tenancy, except four things: a security deposit under 47a-21, an advance payment of the first month’s rent, a deposit for a key or any special equipment, and a tenant screening report fee. The section then adds a flat prohibition in its own sentence: no landlord may charge a tenant a move-in or move-out fee.

The screening fee is regulated rather than banned. A landlord may charge a fee not exceeding fifty dollars plus an adjustment reflecting any increase in the consumer price index for urban consumers, as the Commissioner of Housing determines annually — so the ceiling drifts upward and, like the deposit index, has to be read from the agency rather than assumed. A landlord who charges it must give the prospective tenant a copy of the screening report, or the information needed to request it from the provider, and a copy of the receipt or invoice from the entity that produced it. “Tenant screening report” is defined broadly: a credit report, a criminal background report, an employment history report, a rental history report, or any combination.

The 2025 advertising rule tightens the same theme from the other end. Under 47a-7d a landlord may not advertise, display or offer a unit at a rent that excludes any fee, charge or cost the tenant must pay periodically; those must be prorated into the advertised figure, and that applies even to a monthly default charge the tenant could opt out of. Only a handful of things may sit outside: an actual-cost payment-processing fee where a free alternative exists, pet fees and deposits, submetered or directly billed variable utilities, damage charges beyond normal wear and tear, and one-off service fees such as a lockout or key replacement. See Connecticut tenant screening laws for the screening side.

Who Repairs What in a Connecticut Rental?

Conn. Gen. Stat. 47a-7(a) sets six landlord duties: comply with chapter 368o and all applicable building and housing codes materially affecting health and safety; make all repairs and do whatever is necessary to put and keep the premises in a fit and habitable condition; keep all common areas clean and safe; maintain in good and safe working order all electrical, plumbing, sanitary, heating, ventilating and other facilities and appliances and elevators supplied or required to be supplied; provide and maintain receptacles for ashes, garbage, rubbish and other waste and arrange for removal; and supply running water and reasonable amounts of hot water at all times and reasonable heat.

Two things stand out against other states. Connecticut names elevators expressly, which matters in a housing stock full of older walk-ups and mid-rises. And Connecticut imposes no cooling or air-conditioning duty at all — the heat duty is one-directional. The heat duty also has express carve-outs: it does not apply where the building is not required by law to be equipped for the purpose, or where the unit is built so that heat or hot water is generated by an installation within the tenant’s exclusive control or supplied by a direct public utility connection. Section 47a-7(b) then provides that where a municipal ordinance, building code or fire code imposes a greater duty, that provision takes precedence — so a Hartford or New Haven ordinance can raise the floor above the statute.

Duty-shifting is permitted but channelled. For a single-family residence — which 47a-1 defines with some care, so a unit sharing a wall still qualifies if it has its own street access and shares no heating, hot water or other essential facility — 47a-7(c) lets the parties agree in writing that the tenant performs the waste-removal and water and heat duties and specified repairs, maintenance, alterations or remodeling, provided the transaction is entered into in good faith and not to evade the landlord’s obligations. For any other unit, 47a-7(d) imposes four conditions: good faith, in writing, the work is not needed to cure a failure of the code or habitability duties, and the agreement does not diminish or affect the landlord’s obligations to other tenants.

The tenant’s side is 47a-11, in eight lettered duties: comply with code obligations imposed on tenants; keep the occupied part clean and safe; remove waste to the place the landlord provides; keep plumbing fixtures and appliances clean; use all facilities and appliances, including elevators, reasonably; not wilfully or negligently destroy, deface, damage, impair or remove any part of the premises or let anyone else do so; conduct themselves and require their guests to conduct themselves so as not to disturb neighbours’ peaceful enjoyment or create a nuisance or serious nuisance; and not readmit a household member evicted for using the premises for the illegal sale of drugs. Our Connecticut habitability laws guide covers the standard in more detail.

What Happens When the Heat or Hot Water Fails?

Connecticut gives the tenant a self-help ladder rather than a single remedy, and it is quicker than most. Under Conn. Gen. Stat. 47a-13, where the landlord is required to supply heat, running water, hot water, electricity, gas or another essential service and fails to do so for a reason not beyond the landlord’s control, the tenant may give notice specifying the breach and then elect one of three routes.

The first is repair and deduct for services: procure reasonable amounts of the missing service during the noncompliance and deduct the actual and reasonable cost from the rent. The second is substitute housing where the landlord has not supplied the service within forty-eight hours — and immediately, with no waiting period, where the same failure recurs within six months. Rent abates for the period of noncompliance and the tenant may recover the actual cost of the substitute housing, capped at the rent abated. The third applies where the failure is wilful: the tenant may terminate the lease and recover the greater of two months’ periodic rent or double the actual damages, with all security and prepaid rent and interest returned.

Section 47a-13(b) adds that in any action or defence under the section the tenant may recover reasonable attorney’s fees. The rights do not arise until the tenant has given reasonable written or oral notice, and do not arise at all where the tenant or the tenant’s household caused the condition wilfully or negligently. A separate provision, 47a-14, handles fire and other casualty: where the damage substantially impairs enjoyment through no fault of the tenant, no rent is owed while the impairment lasts, and the tenant may vacate immediately and terminate by written notice given within fourteen days thereafter. And 47a-4a underpins the lot — a rental agreement may not permit the receipt of rent for any period during which the landlord failed to comply with 47a-7(a).

What Notice Comes Before an Eviction in Connecticut?

Connecticut runs two notices, and the order confuses people because the shorter one comes second. For a material breach that is not nonpayment, Conn. Gen. Stat. 47a-15 requires a pretermination notice before any summary process action: written notice specifying the acts or omissions constituting the breach and stating that the rental agreement terminates on a date not less than fifteen days after receipt. If the breach can be remedied by repair or by payment of damages and the tenant adequately remedies it within those fifteen days, the lease does not terminate. Where substantially the same act or omission recurs within six months, the landlord may terminate without serving another pretermination notice. Generate it with our Connecticut notice to cure or quit.

Three situations skip the fifteen-day notice entirely: nonpayment of rent, conduct constituting a serious nuisance, and a violation of 47a-11(h). The statute defines serious nuisance narrowly and it is worth quoting in substance — inflicting bodily harm on another tenant or the landlord, or threatening it with the present ability to carry it out in circumstances a reasonable person would credit; substantial and wilful destruction of part of the unit or premises; conduct presenting an immediate and serious danger to the safety of other tenants or the landlord; or using or allowing the premises to be used for prostitution or the illegal sale of drugs. Serve it with our Connecticut unconditional quit notice.

Then comes the notice to quit possession under 47a-23, which must give at least three days before the date specified in it. The grounds are listed exhaustively: lapse of time; an express stipulation in the lease; violation of the lease or of rules adopted under 47a-9; nonpayment of rent within the grace period; violation of 47a-11; nuisance or serious nuisance; occupation by someone who never had a right to occupy; termination of a right that once existed; the 47a-23c protected-tenant grounds; and certain employment-linked occupancies. The 2025 amendment added an exception worth knowing: nonpayment does not ground a notice to quit where the landlord’s own online rental payment system prevented payment within the grace period.

Form matters. The notice must be in writing substantially in the statutory form set out in 47a-23(b), must state the reason using the statutory language or words of similar import, and an attested copy is served by a proper officer. Delivery may be made on any day of the week. On a month-to-month or week-to-week tenancy, a notice to quit for nonpayment terminates the agreement for that period on delivery and converts the tenancy to a tenancy at sufferance. See Connecticut eviction notice laws for the full sequence.

How Does a Connecticut Tenancy End?

Connecticut sets no periodic-termination notice period at all. This is the single most-repeated error about Connecticut leases. Chapter 830 contains no provision requiring thirty days, or any other number of days, to end a month-to-month tenancy. The requirement is the three-day notice to quit under 47a-23, on the ground of lapse of time or an express stipulation in the lease. If a Connecticut lease contains a longer notice clause, that clause binds the parties as a contract term — but it is the lease doing the work, not the statute.

What Connecticut does regulate on this axis is the rent increase, at forty-five days under 47a-4e, and the protected-tenant regime at 47a-23c. Confusing the two is how the “thirty days” folklore survives: landlords conflate a notice that ends a tenancy with a notice that changes its terms, and Connecticut treats them very differently. A tenant giving notice should use a Connecticut tenant notice to vacate, and a landlord declining to renew a fixed term a Connecticut notice of non-renewal.

Two special exits deserve their own mention. Under 47a-11e a tenant who is a victim of family violence or sexual assault, or whose dependent is, and who reasonably believes it necessary to vacate for fear of imminent harm, may terminate the lease without penalty or liability for the remaining term on at least thirty days’ written notice, supported by a statement made under oath and either a police or court record dated within ninety days or a signed statement from the Office of Victim Services or the Office of the Victim Advocate dated within thirty days. The tenant stays liable for arrears and for damage the tenant caused, and any co-tenant stays liable under the agreement. And under 47a-7b a tenant named as a protected person in a qualifying restraining order can require the locks to be changed — the landlord must answer within six hours and, if doing it, change them within forty-eight hours, charging no more than actual reasonable cost and no additional rent or deposit. See Connecticut lease termination laws and our Connecticut breaking-lease laws guide.

When Is a Connecticut Rental Considered Abandoned?

Conn. Gen. Stat. 47a-11b defines abandonment tightly, because getting it wrong exposes the landlord to an entry-and-detainer action. “Abandonment” means the occupants have vacated without notice to the landlord and do not intend to return — an intention that may be evidenced by removal of substantially all of their possessions and personal effects, together with either nonpayment of rent for more than two months or an express statement that they do not intend to occupy after a specified date.

The procedure is prescriptive. The landlord sends notice to each occupant at the last known address both by regular mail and by certified mail, return receipt requested, stating four things: that the landlord has reason to believe the unit is abandoned; that the landlord intends to reenter and take possession unless the occupant makes contact within ten days of receipt; that the landlord intends to remove any remaining possessions and rerent; and that possessions not reclaimed within thirty days after the notice will be disposed of. The notice must be in clear and simple language and must carry a telephone number and mailing address for the landlord. If the notices come back undeliverable, or the occupant does not make contact within ten days, the landlord may reenter, and any lease still in effect is deemed terminated at that moment.

The landlord must then inventory the occupant’s possessions and keep them not less than thirty days, during which the occupant may reclaim them; after that the landlord may dispose of them as the landlord sees fit. Section 47a-11b(c) is the payoff: no notice to quit and no summary process action are needed for a genuinely abandoned unit — but the same subsection preserves every ordinary obligation where the landlord knows or reasonably should know the unit was not abandoned. Separately, 47a-11a requires the landlord to make reasonable efforts to rerent at a fair rental in mitigation of damages, and provides that where the landlord does not, the agreement is deemed terminated by the landlord as of the date the landlord had notice of the abandonment.

Which Lease Clauses Are Prohibited in Connecticut?

Conn. Gen. Stat. 47a-4(a) lists ten, and several of them are Connecticut-specific enough that an out-of-state template will trip at least one. A rental agreement may not provide that the tenant:

  • Waives or forfeits rights or remedies under chapter 830 and the listed summary-process sections, or under any statute or municipal ordinance, unless that provision expressly says the right may be waived.
  • Authorizes the landlord to confess judgment on a claim arising out of the rental agreement.
  • Agrees to exculpation or limitation of the landlord’s liability arising under law, or to indemnify the landlord for that liability or the costs connected with it.
  • Waives the right to the interest on the security deposit under 47a-21.
  • Permits the landlord to dispossess the tenant without a court order.
  • Consents to distraint of the tenant’s property for rent.
  • Agrees to pay the landlord’s attorney’s fees in excess of fifteen per cent of any judgment against the tenant in an action in which money damages are awarded.
  • Agrees to pay a late charge before the grace period expires, or to pay a reduced rent if paid before the grace period expires.
  • Agrees to pay a late charge exceeding the amounts set out in 47a-15a.
  • Agrees to pay a heat or utilities surcharge where heat or utilities is included in the rental agreement.

The attorney-fee rule is a ceiling, not a ban, and this is the point coverage most often gets wrong in both directions. Connecticut has not prohibited landlord fee clauses; it has capped them. Section 47a-4(a)(7) voids only so much of a clause as exceeds fifteen per cent of a money judgment against the tenant. Conn. Gen. Stat. 42-150aa applies the same ceiling to any consumer contract or lease and adds two further limits: no fee may be received for an attorney who is a salaried employee of the holder, and none may be claimed before a lawsuit is commenced, which kills the customary demand-letter fee. Conn. Gen. Stat. 42-150bb then makes the arrangement reciprocal: where a consumer lease provides for the commercial party’s fee, an attorney’s fee is awarded as a matter of law to the consumer who successfully prosecutes or defends the action. A Connecticut fee clause therefore runs both ways whether the lease says so or not, and the optional clause in the form above generates only that capped, reciprocal version.

The consequence of including a prohibited clause is stated plainly and narrowly. Section 47a-4(b): a provision prohibited by subsection (a) and included in a rental agreement is unenforceable. Connecticut attaches no separate bounty to putting one in — unlike several states, there is no automatic multiple-of-rent penalty for the inclusion itself. The clause simply does not work, and the money remedies live in the individual sections instead: twice the deposit under 47a-21(d)(2), a one-month’s-rent floor under 47a-18a, one month’s rent under 47a-7d, and the greater of two months’ rent or double damages under 47a-13.

Which Disclosures Does Connecticut Actually Require?

Eight under state law, plus the federal lead-paint disclosure — and three of the eight were created between 2023 and 2025, which is why almost every template in circulation is short.

Landlord and manager identification — 47a-6. Written notice, on or before the tenancy begins, of the name and address of the person authorized to manage the premises and of the person authorized to receive all notices, demands and service of process, kept current thereafter. If the landlord does not comply, 47a-6(b) deems the person who entered into the lease for the landlord to be the landlord’s agent for service, for performing the landlord’s obligations under 47a-7 and 47a-13, and for spending collected rent to perform them.

Security deposit escrow and bank identification — 47a-21(h)(4)(A). Written notice within thirty days of the amount held and the name and address of the financial institution holding it.

Fire sprinkler notice — 47a-3f. Where the building is required to be equipped with a fire sprinkler system, the rental agreement itself must state whether an operative system exists, printed in not less than twelve-point boldface type of uniform font; and where one is operative, the agreement must further state the last date of maintenance and inspection, in the same type. This is a disclosure that has to live inside the lease, which is why the generator writes it into the document rather than offering an attachment.

Infestation status — 47a-7a(c). No landlord may offer for rent a unit the landlord knows or reasonably suspects is infested with bed bugs, and before renting the landlord must disclose whether that unit or any contiguous unit the landlord owns, leases or sublets is currently infested. On request the landlord must also disclose the last date the unit was inspected and found free of infestation. The rest of 47a-7a sets the response clock: five business days to inspect after the tenant reports a suspicion, two days to give written notice of the result where the landlord inspected, and five business days to take reasonable treatment measures. A landlord who fails to comply is liable for reasonable attorneys’ fees and the greater of two hundred fifty dollars or the tenant’s actual damages.

Protected tenant rights notice — 47a-23c(e). Since January 1, 2024, whenever a unit in a building or complex of five or more dwelling units, or in a mobile manufactured home park, is rented or the agreement is entered into or renewed, the landlord must give the tenant written notice of the good-cause eviction and fair-rent protections in 47a-23c(b) and (c), on the one-page plain-language form the Commissioner of Housing publishes in English and Spanish.

Pre-occupancy walk-through offer — 47a-7c. For agreements from January 1, 2024, the landlord must offer a joint walk-through before occupancy, on the Department of Housing’s standardized checklist, with both sides signing duplicate copies. The sting is in subsection (b): the landlord may not retain any part of the deposit, or seek payment, for any condition, defect or damage noted on that checklist. A landlord who skips the offer keeps the deduction rights but loses the best evidence of move-in condition.

Standardized rental terms summary form — 47a-7d. On and after April 1, 2026, no landlord may provide a written rental agreement unless a completed copy of the Department of Housing form is the first page of it.

Common interest community notice — 47a-3e. Where a unit in a common interest community is rented from a declarant, a successor declarant, or someone acting on their behalf, that person must give written notice that the unit is in a common interest community before entering into the rental agreement.

Lead-based paint — federal, 42 U.S.C. 4852d. Any dwelling built before 1978 requires the federal disclosure, the EPA pamphlet, and any known records or reports. Our Connecticut lead-based paint disclosure form handles it.

Connecticut does not require a radon, flood-risk, mold, asbestos, methamphetamine, military ordnance, demolition or sex-offender registry disclosure in a residential lease. Each of those comes from another state’s statute book.

Is There a Presumption of Retaliation in Connecticut?

In practice, yes. Conn. Gen. Stat. 47a-20 bars a landlord from maintaining an action to recover possession, demanding a rent increase, or decreasing the services to which the tenant has been entitled within six months after any of five things: the tenant in good faith attempted to remedy a code violation by lawful means, including contacting state or municipal officials or filing a complaint with a fair rent commission; a municipal agency or official filed a notice, complaint or order about such a violation; the tenant in good faith requested repairs; the tenant in good faith instituted an action under 47a-14h; or the tenant organized or became a member of a tenants’ union.

Section 47a-20a then lists the ways out, and Connecticut appellate authority has held that those grounds are exclusive: the tenant’s showing raises a rebuttable presumption of retaliation, and a landlord who does not prove at least one of the four listed grounds has not rebutted it. The four are that the tenant is using the unit for an illegal purpose or in violation of the agreement or is not paying rent; that the landlord seeks in good faith to recover the unit for immediate use as the landlord’s own abode; that the condition complained of was caused by the wilful actions of the tenant’s household or a guest; or that the landlord is proceeding on a notice terminating a periodic tenancy that was given before the tenant’s complaint. A parallel subsection permits a rent increase where the tenant’s household caused the condition through lack of due care, or where the landlord became liable for a substantial increase in property taxes or other operating costs at least four months before the demand and the increase does not exceed the prorated share of it.

Common Mistakes on Connecticut Lease Agreements

  • Charging two months’ deposit to a tenant who is sixty-two or older. The cap is one month under 47a-21(b)(2), and the excess must be refunded on request where a sitting tenant turns sixty-two.
  • Holding the deposit in the landlord’s own account. Section 47a-21(h) requires an escrow account at a financial institution, immediately, and the Banking Commissioner enforces it.
  • Never telling the tenant which bank holds the money. Section 47a-21(h)(4)(A) requires the amount and the bank’s name and address in writing within thirty days.
  • Forgetting the interest, or paying it only at move-out. Section 47a-21(i) requires payment or a rent credit on every anniversary of the tenancy.
  • Drafting a clause that waives deposit interest. Expressly unenforceable under 47a-4(a)(4).
  • Treating the return deadline as a flat number. It is the later of twenty-one days after termination or fifteen days after the forwarding address, and the penalty is twice the deposit.
  • Reciting a twenty-four-hour entry notice. Section 47a-16(c) says reasonable written or oral notice and sets no number; an unlawful entry costs at least one month’s rent under 47a-18a.
  • Charging a late fee on day two. Nine days of grace under 47a-15a(a), and 47a-4(a)(8) voids both an early late fee and an early-payment discount.
  • Charging a late fee every month on the same arrears. Only one charge per delinquent payment under 47a-15a(b).
  • Giving thirty days’ notice to end a month-to-month tenancy and thinking the statute required it. Chapter 830 has no such rule; 47a-23 requires three days to quit.
  • Giving thirty days’ notice of a rent increase. Section 47a-4e requires forty-five.
  • Skipping the fifteen-day pretermination notice for a curable breach. Section 47a-15 makes it a precondition of summary process except for nonpayment, serious nuisance and 47a-11(h).
  • Copying an uncapped attorney-fee clause. Void above fifteen per cent of a money judgment under 47a-4(a)(7), and reciprocal to the tenant under 42-150bb regardless.
  • Charging an application fee, or a move-in or move-out fee. All banned by 47a-4d.
  • Advertising a base rent with mandatory monthly add-ons kept out of it. Section 47a-7d requires the all-in figure.
  • Handing over a lease without the Department of Housing summary form as page one. Required from April 1, 2026, and worth one month’s rent plus the tenant’s fees if omitted.
  • Omitting the sprinkler notice, or putting it in an addendum in normal type. Section 47a-3f requires it in the lease, in twelve-point boldface.
  • Skipping the walk-through offer. Section 47a-7c requires it, and the checklist is the landlord’s own best evidence of move-in condition.
  • Accepting overdue rent and then serving a notice to quit for that same nonpayment. Section 47a-19 treats the acceptance as a waiver.
  • Disposing of an absent tenant’s belongings too early. Section 47a-11b requires dual mailing, a ten-day contact window, an inventory and a thirty-day hold.

Tenant Screening — the First Line of Defense

A well-drafted lease decides who wins a dispute; screening decides whether there is one. Connecticut’s remedies put real money on the outcome — twice the deposit for a botched return, a one-month’s-rent floor for an unlawful entry, one month’s rent for a missing summary form — and several of them turn on the landlord’s own compliance long before the tenant’s conduct is reached. Verifiable income, a clean payment history, and no prior eviction filings remain the strongest predictors of a quiet tenancy. Note that Connecticut regulates the screening step itself under 47a-4d: the fee is capped, and the applicant is owed a copy of the report and the receipt. Our tenant screening report covers credit, eviction filings, criminal background, and employment verification. Screen first, then paper the tenancy with this lease, and keep our Connecticut pet and assistance animal guide to hand before writing a pet clause.

Bottom line

A Connecticut lease is governed by Connecticut General Statutes chapter 830 at 47a-1 and following. The deposit is capped at two months’ rent, or one month where the tenant is sixty-two or older, must sit in an escrow account whose name and address the tenant is told within thirty days, and must earn interest paid or credited every anniversary at the rate the Banking Commissioner sets each year. It comes back within the later of 21 days from termination or fifteen days from the forwarding address, or the landlord owes twice it. Entry takes reasonable notice with no fixed hours, and an unlawful entry costs at least one month’s rent. Rent has nine days of grace and one capped late charge. Ending a month-to-month tenancy takes a three-day notice to quit; curing another breach takes fifteen; raising the rent takes forty-five. Disclose the landlord, the escrow bank, the sprinkler status, any infestation, protected-tenant rights and the walk-through offer — and from April 2026 put the Department of Housing summary form in front as page one.

Frequently Asked Questions

How much can a Connecticut landlord charge for a security deposit?

Two months’ rent, or one month’s rent where the tenant is sixty-two years of age or older. Conn. Gen. Stat. 47a-21(b) sets both tiers, and where a sitting tenant turns sixty-two after paying a larger deposit the landlord must return the excess on request. An advance payment of the first month’s rent, and a deposit for a key or special equipment, are not security deposits at all under 47a-21(a), so neither counts toward the cap.

Does a Connecticut landlord have to pay interest on a security deposit?

Yes. Conn. Gen. Stat. 47a-21(i) requires interest at not less than the deposit index. Under 36a-26 the Banking Commissioner determines that index for each calendar year and publishes it on the Department of Banking website by December fifteenth of the prior year, so the rate changes annually and must be read from the department rather than assumed. Interest is paid or credited toward the next rent on each anniversary of the tenancy, and a clause waiving it is unenforceable under 47a-4(a)(4).

How long does a Connecticut landlord have to return the security deposit?

The later of twenty-one days after termination of the tenancy or fifteen days after the landlord receives written notice of the tenant’s forwarding address, under 47a-21(d)(2). The landlord delivers the deposit plus accrued interest, or the balance plus a written statement itemizing each deduction. A landlord who gets it wrong is liable for twice the amount of the deposit, and for ten dollars or twice the accrued interest where the only failure was the interest.

Where must a Connecticut security deposit be held?

In an escrow account at a financial institution, immediately, for the benefit of the tenant, under 47a-21(h)(1). The deposit remains the tenant’s property in which the landlord holds only a security interest, is exempt from attachment by the landlord’s creditors, and is not part of the landlord’s estate. Within thirty days the landlord must give written notice of the amount held and the name and address of the institution holding it.

How much notice must a Connecticut landlord give before entering?

Reasonable written or oral notice, with entry only at reasonable times. Conn. Gen. Stat. 47a-16(c) sets no number of hours and no number of days, and forbids abusing the right of entry or using it to harass. A lease reciting a twenty-four-hour rule for Connecticut is reciting a rule the statute does not contain. Under 47a-18a an unlawful entry, or repeated harassing demands for entry, costs the landlord actual damages of not less than one month’s rent plus reasonable attorney’s fees.

What is the grace period for rent in Connecticut?

Nine days, or four days on a one-week tenancy, under 47a-15a(a). Since January 1, 2026 the grace period is extended a further five days where the landlord’s own online rental payment system prevents payment when due, and 47a-23 was amended so nonpayment in that situation does not ground a notice to quit. A clause charging a late fee before the grace period expires, or discounting rent paid before it expires, is unenforceable under 47a-4(a)(8).

How much can a Connecticut landlord charge as a late fee?

The lesser of five dollars per day up to a maximum of fifty dollars, or five per cent of the delinquent rent payment, under 47a-15a(b). Where rent is paid in whole or in part by a governmental or charitable entity, the five per cent is measured against the tenant’s share. Only one late charge may be assessed on a delinquent payment however long the rent stays unpaid, and a charge above these limits is unenforceable under 47a-4(a)(9).

How much notice does a Connecticut rent increase need?

Forty-five days. Conn. Gen. Stat. 47a-4e, effective October 2024, makes an increase ineffective unless the landlord gave written notice not less than forty-five days before it takes effect, with an equivalent shorter period for a term of one month or less. The tenant’s failure to respond is not agreement, and the section does not permit an increase during the term of an existing agreement.

Can a Connecticut lease make the tenant pay the landlord’s attorney’s fees?

Only up to fifteen per cent of a money judgment. Section 47a-4(a)(7) voids a clause requiring the tenant to pay the landlord’s attorney’s fees in excess of fifteen per cent of any judgment against the tenant in an action awarding money damages. Conn. Gen. Stat. 42-150aa adds that no fee is collectable for a salaried in-house attorney or before a lawsuit is commenced, and 42-150bb awards a fee to the tenant as a matter of law where the tenant successfully prosecutes or defends. The clause is lawful, capped and reciprocal.

How much notice ends a Connecticut month-to-month tenancy?

Three days. Connecticut sets no separate periodic-termination notice period anywhere in chapter 830; the requirement is the notice to quit possession under 47a-23, giving at least three days before the date specified in it. The widely repeated thirty-day figure is not in the statute book, though a lease may of course promise longer. What Connecticut does require, since October 2024, is forty-five days’ notice of a rent increase.

What is the fifteen-day notice in Connecticut?

The pretermination notice under 47a-15. Before starting a summary process action for a material noncompliance with 47a-11 or with the lease or the landlord’s rules, the landlord must deliver written notice specifying the acts or omissions and stating that the agreement terminates not less than fifteen days after receipt. If the breach is curable by repair or payment and the tenant cures it within those fifteen days, the lease does not terminate. It is not required for nonpayment of rent, for a serious nuisance, or for a violation of 47a-11(h).

Which tenants have good-cause eviction protection in Connecticut?

Under 47a-23c, a tenant who is sixty-two or older, or who has a qualifying physical or mental disability, or who lives with such a spouse, sibling, child, parent or grandparent, and who lives in a building or complex of five or more dwelling units or in a mobile manufactured home park. Such a tenant may be dispossessed only for one of the listed causes and the rent raised only so far as is fair and equitable. Since January 1, 2024 the landlord must hand that tenant the Department of Housing rights notice on every rental and renewal.

Can a Connecticut landlord charge an application fee?

No. Conn. Gen. Stat. 47a-4d bans any payment, fee or charge for processing, reviewing or accepting a rental application, and bans move-in and move-out fees outright. The only permitted pre-tenancy charges are the security deposit, an advance payment of the first month’s rent, a key or special-equipment deposit, and a tenant screening report fee capped at fifty dollars plus an annual consumer price index adjustment set by the Commissioner of Housing. A landlord charging it must give the applicant the report and a copy of the receipt.

What is the standardized rental terms summary form?

A one-page Department of Housing form that 47a-7d requires to be the first page of every written Connecticut rental agreement on and after April 1, 2026. It summarises the term, the landlord’s name, the property-management point of contact, each tenant’s name and the total periodic rent computed on the all-in basis the same section requires of advertised rent. Omitting it costs a civil penalty equal to one month’s rent plus the tenant’s reasonable attorney’s fees and costs.

Does a Connecticut lease need to be notarized?

No. Connecticut requires no subscribing witnesses and no notary for an ordinary residential lease. But 47a-3b makes a tenancy month to month where the agreement fixes no definite term, and 47a-3d provides that holding over is not evidence of any further lease and that a parol lease reserving a monthly rent with no agreed termination date is a lease for one month only. Anything longer than a month should be written down.

When is a Connecticut rental considered abandoned?

When the occupants have vacated without notice and do not intend to return, shown by removal of substantially all their possessions plus either nonpayment of rent for more than two months or an express statement that they will not occupy after a stated date, under 47a-11b. The landlord then notifies each occupant at the last known address by both regular and certified mail, waits ten days for contact, inventories the possessions and holds them not less than thirty days. No notice to quit is needed for a genuinely abandoned unit.

Is there a presumption of retaliation in Connecticut?

Yes in practice. Section 47a-20 bars a landlord from seeking possession, demanding a rent increase or decreasing services within six months after five protected tenant acts, including a good-faith repair request and joining a tenants’ union. Section 47a-20a supplies four grounds on which the landlord may rebut, and Connecticut appellate authority treats those grounds as exclusive, so a landlord who proves none of them has not rebutted the presumption.

Does a Connecticut landlord have to provide air conditioning?

No. Conn. Gen. Stat. 47a-7(a)(6) requires running water and reasonable amounts of hot water at all times and reasonable heat, and names no cooling duty. It does name elevators expressly in 47a-7(a)(4), which many states omit. Where a municipal ordinance or building or fire code imposes a greater duty, 47a-7(b) gives that provision precedence, so a local ordinance can raise the standard above the statute.

Legal Disclaimer: This Connecticut residential lease agreement generator is provided for general informational purposes only and is not legal advice. Connecticut’s landlord-tenant law changed substantially between 2023 and 2025, and several provisions on this page took effect in 2024, 2025 or 2026, so a lease drafted from an older template can be non-compliant on its face. A prohibited lease provision, a deposit held outside escrow, an unpaid year of deposit interest, or an itemized statement delivered late can each expose a landlord to statutory damages. The security deposit interest rate is reset every calendar year by the Banking Commissioner and must be read from the Department of Banking, never assumed.
