Delaware has no statewide rent cap on how much you can raise the rent, but state law sets firm timing rules: a month-to-month tenancy needs at least 60 days’ written notice (25 Del. C. 5106), and a renewal with a rent change needs 60 days’ written notice before the term ends (25 Del. C. 5107). Generate a clean notice below.

This Delaware Rent Increase Notice raises the rent on a residential tenancy. Delaware sets no statewide cap on the amount, but it does fix the notice: a month-to-month tenancy needs at least 60 days’ written notice under 25 Del. C. 5106, and renewing a lease with a rent change needs at least 60 days’ written notice before the term expires under 25 Del. C. 5107 (the tenant then has until 45 days before the term ends to object). Keep the increase out of the retaliation bar in Section 5516. Our how to raise rent guide covers the timing, and the tenant screening laws by state hub helps you place reliable tenants in the first place.

Delaware note: Delaware has no statewide rent-control law and no statute that caps the amount of an increase, and there is no county or city rent control either. (A 2024 bill, HB 455, proposed a CPI-tied renewal cap but died in committee and was never enacted, so no cap is in force.) What the law constrains is timing and motive. Under 25 Del. C. 5106 a month-to-month tenancy requires at least 60 days’ written notice, counted from the first day of the month after actual notice, to change or end it. Under 25 Del. C. 5107, a landlord renewing a lease with modified terms – which includes a rent increase – must give at least 60 days’ written notice before the agreement expires, and the tenant has until 45 days before the term ends to give notice of an intent to terminate rather than accept the new terms. A fixed-term rent cannot change mid-term unless the lease allows it, and Section 5516 forbids raising rent in retaliation for a protected tenant action.

Delaware rent-increase rules at a glance

Delaware does not cap the amount of rent, but it fixes the notice. For a month-to-month tenancy, 25 Del. C. 5106 requires at least 60 days’ written notice (the 60-day period begins on the first day of the month after actual notice). To renew a lease with a rent change, 25 Del. C. 5107 requires at least 60 days’ written notice before the term expires, stating the new rent and effective date; unless the tenant gives notice to terminate at least 45 days before the last day of the term, the new terms are deemed accepted. Rent cannot change mid-term on a fixed lease unless the lease allows it, and an increase may not be retaliatory (25 Del. C. 5516).

How to Serve the Delaware Rent Increase Notice

Delaware Playbook

Determine the required notice period

Confirm the tenancy and the lease. On a written-lease fixed term the rent is locked unless the lease has an escalation clause, and a change rides at renewal under 25 Del. C. 5107; a month-to-month tenancy is changed prospectively with proper written notice under 25 Del. C. 5106.

Calculate the increase

Pick the right 60-day track. For a month-to-month tenancy, 25 Del. C. 5106 requires at least 60 days’ written notice, and that 60-day period begins on the first day of the month following actual notice. To raise the rent at renewal of a term lease, 25 Del. C. 5107 requires at least 60 days’ written notice before the agreement expires.

Prepare the written notice

On a renewal, state the modified terms in the notice – the new rent, any deposit change, and the effective date – and remember the tenant has until 45 days before the last day of the term to give notice of an intent to terminate (25 Del. C. 5107); if the tenant does not, the new terms are deemed accepted.

Serve the notice

Make sure the timing is not retaliatory. 25 Del. C. 5516 bars raising the rent in response to a tenant’s protected action, and an increase within 90 days of that action is presumed retaliatory; you can rebut only by showing the rent does not exceed what other tenants of similar units in the same complex pay.

Document and follow up

Put the increase in writing – the current rent, the new rent, and the effective date – and serve it by a method 25 Del. C. 5113 recognizes (personal delivery, a copy left at the unit with an adult, or registered/certified or first-class mail with a certificate of mailing), then keep a signed, dated copy with the return receipt or certificate of mailing as proof.

Generate the Delaware Notice

Complete the fields below to generate a Delaware rent increase notice. The new rent and effective date must give the tenant the full statutory notice period. Service should comply with 25 Del. C. 5113; retain proof of service.

Set the effective date correctly

Count the full 60-day notice period before the new rent takes effect. On a month-to-month tenancy (25 Del. C. 5106), the 60 days begin on the first day of the month after the tenant actually receives the notice – so an increase served mid-month does not start its clock until the first of the next month. On a renewal (25 Del. C. 5107), serve the 60-day notice before the term expires and remember the tenant can object up to 45 days before the term ends. An effective date that arrives before the 60-day period closes makes the increase unenforceable. Allow added days for receipt when you mail.

About This Delaware Notice

A Delaware rent increase notice is the written notice a landlord gives to raise the rent on a residential tenancy. Delaware is a market-rate state: there is no statewide rent control and no statutory cap on how much the rent can go up, and there is no county or city rent control either. A 2024 bill, House Bill 455, proposed a ten-year program tying renewal increases to a CPI-based 5 to 7 percent cap, but it died in the House Housing Committee and was never enacted – so for Delaware rentals there is still no cap on the amount of an increase. What the law regulates instead is the notice the tenant must get, when an increase can take effect, and why it is being made.

The controlling question is the type of tenancy. On a month-to-month tenancy, 25 Del. C. 5106 governs: the landlord (like the tenant) must give at least 60 days’ written notice to change or end the agreement, and that 60-day period begins on the first day of the month following the day of actual notice. So a notice handed to a tenant in the middle of June does not start its 60-day clock until July 1, and the new rent takes effect 60 days after that. Because raising the rent on a periodic tenancy is effectively offering new terms going forward, the landlord uses this 60-day notice, and a tenant who will not pay the new rent gives 60 days’ notice of their own to move out.

On a term lease, the rent is locked for the term and cannot be raised mid-lease unless the lease itself contains an escalation clause; a change rides at renewal. There, 25 Del. C. 5107 controls. When a landlord intends to renew a rental agreement subject to amended or modified provisions – and a rent increase is exactly that – the landlord must give the tenant at least 60 days’ written notice before the agreement expires, and the notice has to specify the modified provisions, the amount of any rent or security deposit, and the date the changes take effect. The tenant then has a window of their own: unless the tenant notifies the landlord of an intent to terminate the existing agreement at least 45 days before the last day of the term, the amended terms are deemed accepted. One carve-out applies under 5107 – where the tenant’s rent and security deposit are a function of the tenant’s income under HUD regulations, the HUD rules govern instead.

Even with proper timing and notice, an increase can still be unlawful because of its motive. 25 Del. C. 5516 prohibits a landlord from retaliating against a tenant – including by demanding increased rent, decreasing services, or seeking possession – after the tenant takes a protected action, such as complaining in good faith of a building, housing, or sanitary code violation to the landlord or a government authority, having a government authority cite a violation, organizing or serving as an officer of a tenants’ organization, or pursuing a legal right or remedy arising from the tenancy. If the landlord acts within 90 days of that protected act, the conduct is presumed retaliatory; for a rent increase, the landlord can rebut the presumption only by showing, with competent evidence, that the rent now demanded does not exceed the rent charged other tenants of similar units in the same complex. A tenant who proves an unlawful retaliatory dispossession can recover three months’ rent or treble the damages sustained, whichever is greater, plus the cost of suit. Federal and Delaware fair housing law independently bar an increase aimed at a tenant because of a protected characteristic.

Service of the notice follows 25 Del. C. 5113. The landlord may serve the tenant personally, leave a copy at the rental unit or usual place of abode with an adult residing there, or send it by registered or certified mail or by first-class mail with a certificate of mailing, addressed to the tenant at the leased premises. The return receipt – signed, refused, or unclaimed – or the certificate of mailing is prima facie evidence that the notice was served, which is why a provable written method matters. Whatever the method, the notice should state the current rent, the new rent, and the effective date, and the landlord should keep a signed, dated copy with the receipt or certificate. Our how to raise rent guide walks through the timing, and screening applicants with verified reports keeps tenancies stable so the increases you serve actually stick.

Put together, a clean Delaware increase is simple but exact: pick the right track – 60 days’ written notice on a month-to-month tenancy under 25 Del. C. 5106, counted from the first of the next month, or 60 days’ written notice before the term ends to renew with a rent change under 25 Del. C. 5107, with the tenant’s 45-day objection window – never raise rent mid-term on a fixed lease that does not allow it, keep the timing outside the 90-day retaliation presumption of Section 5516, serve the notice by a 25 Del. C. 5113 method with proof, and never let the increase track a tenant’s protected complaint. None of this replaces the screening you do at move-in – a tenant chosen for steady income and a clean payment history is the one most likely to absorb a lawful increase without a dispute.

Delaware Statutory Requirements

  • No statewide cap on the amount of a rent increase, and no state, county, or city rent control (HB 455’s proposed CPI cap died in committee and is not law).
  • At least 60 days’ written notice on a month-to-month tenancy — 25 Del. C. 5106, the 60 days starting the first day of the month after actual notice.
  • At least 60 days’ written notice before the term expires to renew with a rent change — 25 Del. C. 5107, stating the new rent and effective date.
  • Tenant’s 45-day objection window on a renewal — unless the tenant gives notice to terminate at least 45 days before the term ends, the new terms are deemed accepted (25 Del. C. 5107).
  • No mid-term increase on a fixed-term lease unless the lease expressly allows it.
  • No retaliatory increase — 25 Del. C. 5516, with an increase within 90 days of a protected act presumed retaliatory.
  • No discriminatory increase based on a protected class (federal Fair Housing Act and Delaware’s Fair Housing Act).

Service Methods Permitted

  • 25 Del. C. 5113 recognizes personal service on the tenant, or a copy left at the rental unit or usual abode with an adult residing there.
  • In the alternative, 25 Del. C. 5113(c) allows posting the notice on the rental unit combined with a return receipt or certificate of mailing, or personal service by a special process-server appointed by the Court.
  • Registered or certified mail, or first-class mail with a certificate of mailing, addressed to the tenant at the leased premises — the return receipt or certificate of mailing is prima facie evidence of service.
  • Allow added days for receipt when you mail, and on a month-to-month tenancy remember the 60 days do not start until the first of the next month.
  • Email or text works only if the lease or tenant authorizes electronic notice and you document it; keep the send record either way.

Common Mistakes

  • Giving less than 60 days’ written notice on a month-to-month tenancy (25 Del. C. 5106).
  • Missing the 60-day-before-expiration deadline to renew with a rent change (25 Del. C. 5107).
  • Forgetting that the 5106 clock starts on the first day of the month after the tenant actually gets the notice.
  • Raising the rent mid-term on a fixed-term lease that does not allow it.
  • Serving an increase within 90 days of a tenant’s habitability complaint or tenants’-association activity — 25 Del. C. 5516 presumes that retaliatory.
  • Relying on a verbal notice with no written record or proof of service.

Best Practices

  • Identify the track first — month-to-month (5106) or renewal-with-modifications (5107) — both need 60 days’ written notice.
  • State the current rent, the new rent, and the effective date plainly, and on a renewal name the modified terms.
  • Count the 60 days carefully, and on a month-to-month start the count from the first of the month after the tenant receives it.
  • Serve by a 25 Del. C. 5113 method you can prove, keep the return receipt or certificate of mailing, and avoid timing an increase right after a tenant complaint.

Manufactured & Mobile-Home Lot Rent Follows Different Rules

If you rent lot space in a manufactured-home (mobile-home) community rather than an ordinary house or apartment, the 25 Del. C. 5106 and 5107 timing above does not control the increase. Lot rent falls under the Manufactured Homes and Manufactured Home Communities Act (Delaware Code Title 25, Chapter 70), which sets a stricter, separate regime because a homeowner who owns the home but rents the ground cannot easily move it.

Under 25 Del. C. 7051, a community owner may not increase a tenant’s lot rent more than once in any 12-month period, and must give written notice of the increase at least 90 days, but no more than 120 days, before the new rent is first due – delivered to each affected homeowner, to the homeowners’ association if one exists, and to the Delaware Manufactured Home Relocation Authority (DEMHRA). The notice has to identify the affected homeowners by lot number, name, group, or phase.

Chapter 70 also imposes a rent-justification standard (25 Del. C. 7050, 7052, 7052A, and 7052B): a lot-rent increase must be tied to the factors the statute permits and can be challenged by the homeowners through DEMHRA’s arbitration process, and 25 Del. C. 7051A can block an increase while an uncorrected health-or-safety violation exists in the community. None of that applies to a standard apartment or single-family rental – for those, the 60-day rules above are what govern.

Does a bigger increase need more notice?

No. For an ordinary Delaware residential tenancy the notice is 60 days regardless of the dollar amount or percentage of the increase – 25 Del. C. 5106 and 5107 set no size threshold. Ignore any “increases under 20 percent only need 30 days” rule of thumb; that is not Delaware residential law. The one Delaware increase that carries a longer notice is manufactured-home lot rent, at 90 to 120 days under Chapter 70.

Subsidized Units, Commercial Leases & a Rejected Renewal

HUD and income-based housing. Where a tenant’s rent and security deposit are set as a function of the tenant’s income under U.S. Department of Housing and Urban Development (HUD) rules, 25 Del. C. 5107(d) hands the increase to the HUD regulations rather than the 60-day renewal mechanics, and 25 Del. C. 5106(e) provides that for a federally-subsidized unit federal law controls over any conflicting term of the state Code. If you manage a Section 8, LIHTC, or public-housing unit, follow the program’s rent-adjustment procedure instead of the general 60-day rule.

Commercial leases. The Residential Landlord-Tenant Code does not reach commercial space – 25 Del. C. 5101(b) excludes commercial rental units, which are governed by general contract law and the lease itself. The 60-day notice and the retaliation bar described here apply to residential tenancies only.

If the tenant rejects a renewal increase. On a 25 Del. C. 5107 renewal, the tenant accepts the new rent by staying past the 45-day objection deadline. Under 25 Del. C. 5107(c), a tenant who instead rejects the modified terms has, in effect, given an effective termination notice – the tenancy ends at the term rather than renewing at the old rent, so plan for a possible vacancy when you set an aggressive renewal number.

Where a tenant can push back. A tenant who believes an increase is retaliatory, discriminatory, or served without the required 60 days can raise it as a defense in a Justice of the Peace Court summary-possession case, and can contact the Delaware Department of Justice Consumer Protection Unit about a landlord-tenant complaint. That is why a clean, dated, provably-served notice at the lawful notice period is the landlord’s best protection.

Bottom line

In Delaware there is no statewide rent cap, but a lawful increase turns on timing and motive: at least 60 days’ written notice on a month-to-month tenancy (25 Del. C. 5106), at least 60 days’ written notice before the term ends to renew with a rent change (25 Del. C. 5107, with the tenant’s 45-day objection window), no mid-term change on a written-lease fixed term, and nothing inside the retaliation bar of Section 5516.

Frequently Asked Questions

How much notice is required for a Delaware rent increase?

At least 60 days. For a month-to-month tenancy, 25 Del. C. 5106 requires at least 60 days’ written notice, and the 60-day period begins on the first day of the month following the day the tenant actually receives the notice. To raise the rent at renewal of a term lease, 25 Del. C. 5107 requires at least 60 days’ written notice before the agreement expires. Either way, the notice must be in writing and state the new rent and effective date.

Is there a cap on rent increases in Delaware?

No. Delaware has no statewide rent control and no cap on the amount of an increase, and there is no county or city rent control. A 2024 bill (House Bill 455) proposed a CPI-tied renewal cap, but it died in committee and was never enacted. The real limits are the 60-day notice (25 Del. C. 5106 for month-to-month, 25 Del. C. 5107 for a renewal with modifications), no mid-term increase on a fixed lease, and the retaliation and fair-housing bars.

How often can a landlord raise rent in Delaware?

It depends on the tenancy. On a month-to-month tenancy, 25 Del. C. 5106 lets the landlord change the rent prospectively with at least 60 days’ written notice, starting the first of the month after actual notice. On a term lease, the rent is locked for the term and a change rides at renewal under 25 Del. C. 5107, which needs 60 days’ notice before the term ends. There is no fixed minimum interval between increases in the statute.

Can a landlord raise rent during a fixed-term Delaware lease?

Not during the fixed term. On a written-lease fixed term the rent is locked unless the lease has an escalation clause, and any increase takes effect at renewal under 25 Del. C. 5107 (60 days’ written notice before the term expires, with the tenant’s 45-day objection window). A month-to-month tenancy can be increased prospectively with at least 60 days’ written notice under 25 Del. C. 5106.

Can a rent increase be illegal in Delaware?

Yes, indirectly. 25 Del. C. 5516 bars a landlord from raising the rent in retaliation after a tenant complains in good faith of a code or sanitary violation, organizes or is an officer of a tenants’ organization, or pursues a legal right or remedy. An increase within 90 days of the protected act is presumed retaliatory, and the landlord can rebut only by showing the rent does not exceed what other tenants of similar units in the same complex pay. A tenant who proves unlawful retaliation can recover three months’ rent or treble damages, whichever is greater, plus costs. An increase that violates the 60-day notice rule is also unenforceable.

What happens if the tenant doesn’t pay the new rent?

If the increase is on a month-to-month tenancy served with at least 60 days’ written notice (or a renewal handled under 25 Del. C. 5107) and outside the retaliation bar, the tenant either pays the new rent or gives the required notice and moves out. If the tenant stays and pays only the old amount after a valid increase, the shortfall is unpaid rent the landlord can address with a demand for compliance or possession under Delaware’s landlord-tenant law.

What are common mistakes that invalidate the notice?

The usual errors are giving less than 60 days’ written notice on a month-to-month tenancy (25 Del. C. 5106), missing the 60-day-before-expiration deadline on a renewal (25 Del. C. 5107), forgetting that the month-to-month clock starts the first of the next month, raising rent mid-term on a fixed lease that does not allow it, timing the increase inside the 90-day retaliation presumption of 25 Del. C. 5516, and relying on a verbal notice with no proof of service. Any one of these can make the increase unenforceable.

How much notice is required to raise mobile-home lot rent in Delaware?

Longer than for a house or apartment. Lot rent in a manufactured-home community is governed by Delaware Code Title 25, Chapter 70, not by 25 Del. C. 5106 or 5107. Under 25 Del. C. 7051 the community owner may raise a tenant’s lot rent only once in any 12-month period and must give written notice at least 90 days, but no more than 120 days, before the increased rent is first due, sent to each affected homeowner, the homeowners’ association if there is one, and the Delaware Manufactured Home Relocation Authority (DEMHRA). Chapter 70 also lets homeowners challenge an unjustified increase through DEMHRA.

Does a larger rent increase require more notice in Delaware?

No. For an ordinary residential tenancy the notice is 60 days no matter how large the increase is – 25 Del. C. 5106 and 5107 set no percentage or dollar threshold, so a 3 percent increase and a 30 percent increase both need 60 days’ written notice. The idea that a smaller increase only needs 30 days is not Delaware residential law. The only Delaware rent increase that carries a longer notice is manufactured-home lot rent, at 90 to 120 days under Chapter 70.

Do Delaware’s rent increase rules apply to HUD or income-based housing?

Not in the same way. Under 25 Del. C. 5107(d), when the rent and security deposit are a function of the tenant’s income under HUD regulations, the HUD rules govern the adjustment instead of the 60-day renewal mechanics, and 25 Del. C. 5106(e) provides that federal law controls over a conflicting state provision for a federally-subsidized unit. For Section 8, LIHTC, or public-housing units, follow the program’s own rent-adjustment procedure.

Do Delaware rent increase rules apply to commercial leases?

No. 25 Del. C. 5101(b) excludes commercial rental units from the Residential Landlord-Tenant Code; a commercial rent increase is governed by general contract law and the terms of the lease itself. The 60-day notice, the retaliation bar, and the service rules on this page apply to residential tenancies only.

What happens if the tenant rejects a renewal rent increase?

Under 25 Del. C. 5107, a tenant accepts the modified terms by staying past the 45-day objection deadline. If the tenant instead rejects the modified terms, 25 Del. C. 5107(c) treats that rejection as an effective termination notice, so the tenancy ends when the term expires rather than renewing at the old rent. A landlord setting an aggressive renewal increase should plan for the possibility that the tenant leaves.

Where can a Delaware tenant complain about an unlawful rent increase?

A tenant can raise an unlawful increase – one that is retaliatory, discriminatory, or served with less than the required 60 days – as a defense in a Justice of the Peace Court summary-possession action, and can contact the Delaware Department of Justice Consumer Protection Unit about a landlord-tenant complaint. Because the tenant can challenge a defective notice, a landlord’s safest course is a written notice served by a provable method at the full statutory notice period.
