Free Illinois Repair and Deduct Letter

A repair-and-deduct letter is the written notice that starts a statutory clock: it tells the landlord a repair is required, that the tenant intends to have it done at the landlord’s expense, and it fixes the date everything afterwards is measured from. In Illinois that letter is not a courtesy or a negotiating position. It is a condition of the remedy. 765 ILCS 742 — the Residential Tenants’ Right to Repair Act — gives the tenant the right to have a repair made and take the cost off the rent, and it hangs that right on a specific notice, sent a specific way, followed by a specific wait, followed by a specific proof. Miss one of them and § 742/15 and § 742/20 take the remedy away entirely. This page walks the Act in the order it actually applies, starting with the two questions that decide whether it is available to you at all.

The letter carries more legal weight in Illinois than in most places, because § 742/5 specifies what it must do and how it must travel. It has to be in writing; it has to go by registered mail, certified mail or another restricted delivery service; it has to reach the address the lease gives for the landlord or the landlord’s agent, or failing that the landlord’s last known address; and its content has to convey “the tenant’s intention to have the repair made at the landlord’s expense.” That last point is the one tenants skip. A letter that merely reports a broken water heater is a maintenance request, not a § 742/5 notice, and the 14 days do not begin on a maintenance request. The generator above builds a letter that states the intention in terms, identifies the condition and the unit, records the date, and leaves room for the reasonable cost estimate that shows the entry test was applied before the notice went out. Keep the mailing receipt and the return card with your copy: the date of notice is the date every later step is measured from, and if the deduction is ever questioned it is the first thing anyone will ask you to prove.

• The tenant’s full name and the address of the unit, including the unit number.
• The landlord’s name and the notice address as the lease gives it — or, if the lease lists none, the landlord’s last known address, which is the fallback § 742/5 names.
• The date the letter is sent, because the 14 days in § 742/5 run from notification.
• A specific description of the condition and where it is, rather than a general complaint.
• The basis on which the repair is required — the lease, a law, an administrative rule, or a local ordinance or regulation.
• An express statement of the tenant’s intention to have the repair made at the landlord’s expense. This is the sentence that makes it a § 742/5 notice.
• The reasonable cost of the repair, which is what the entry test is applied to.
• A statement that the tenant will proceed if the repair is not made within 14 days, or sooner if the condition is an emergency as § 742/5 defines emergency.
• The delivery method used, so the file shows registered or certified mail or another restricted delivery service was chosen.
• A note that the paid bill and the tradesman’s name, address and telephone number will be submitted to the landlord before any deduction is taken.
• The tenant’s signature and the date, with a retained copy and the mailing receipt.

• Reading § 742/10(e) as “or”. It removes property that is owner-occupied and has 6 or fewer dwelling units. Tenants of small absentee-owned buildings are covered, and are told otherwise constantly.
• Hand-delivering or emailing the notice. § 742/5 names registered mail, certified mail or another restricted delivery service. A method the statute does not name is a gap the landlord can point at later.
• Sending a repair request instead of a notice of intention. The statute counts 14 days from a notice of “the tenant’s intention to have the repair made at the landlord’s expense.”
• Doing the work yourself. The deduction follows a paid bill “from an appropriate tradesman or supplier unrelated to the tenant.” Tenant labour produces no such bill, and neither does a relative’s.
• Using the Act for a condition you or your household caused. § 742/5 bars repair at the landlord’s expense where the condition was caused by the deliberate or negligent act or omission of the tenant, a family member, or another person on the premises with the tenant’s consent.

Yes. Illinois gives residential tenants a statutory repair-and-deduct remedy in 765 ILCS 742/5, part of the Residential Tenants’ Right to Repair Act. The Act was created by Public Act 93-891 and took effect on 1 January 2005. It is short — sections 1, 5, 10, 15, 20, 25 and 30 are the whole of it — and it is narrow. It applies to small repairs, it excludes six categories of property outright, it prescribes how the notice must travel, it sets a 14-day wait, it dictates who may do the work, and it makes the remedy conditional on the tenant complying with every one of those requirements.

One framing point before the detail. Repair and deduct is self-help. Nobody signs off on it in advance; no inspector certifies it; no court authorises it. The tenant acts, and the correctness of the tenant’s steps is tested afterwards, usually when the landlord treats the deduction as unpaid rent. That is why § 742/15 and § 742/20 matter as much as § 742/5 does, and why the paperwork you keep is not administrative tidiness but the evidence the remedy stands or falls on.

Here is the operative section as enacted, in full and unabridged. Section 5 is captioned “Repair; deduction from rent” and reads:

“If a repair is required under a residential lease agreement or required under a law, administrative rule, or local ordinance or regulation, and the reasonable cost of the repair does not exceed the lesser of $500 or one-half of the monthly rent, the tenant may notify the landlord in writing by registered or certified mail or other restricted delivery service to the address of the landlord or an agent of the landlord as indicated on the lease agreement; if an address is not listed, the tenant may send notice to the landlord’s last known address of the tenant’s intention to have the repair made at the landlord’s expense. If the landlord fails to make the repair within 14 days after being notified by the tenant as provided above or more promptly as conditions require in the case of an emergency, the tenant may have the repair made in a workmanlike manner and in compliance with the appropriate law, administrative rule, or local ordinance or regulation. Emergencies include conditions that will cause irreparable harm to the apartment or any fixture attached to the apartment if not immediately repaired or any condition that poses an immediate threat to the health or safety of any occupant of the dwelling or any common area. After submitting to the landlord a paid bill from an appropriate tradesman or supplier unrelated to the tenant, the tenant may deduct from his or her rent the amount of the bill, not to exceed the limits specified by this Section and not to exceed the reasonable price then customarily charged for the repair. If not clearly indicated on the bill submitted by the tenant, the tenant shall also provide to the landlord in writing, at the time of the submission of the bill, the name, address, and telephone number for the tradesman or supplier that provided the repair services. A tenant may not repair at the landlord’s expense if the condition was caused by the deliberate or negligent act or omission of the tenant, a member of the tenant’s family, or another person on the premises with the tenant’s consent.”

Nothing in that quotation has been shortened and no clause has been cut before its operative end. The threshold figure is $500, and the Act writes it as a numeral, exactly as reproduced above — along with “14 days” and, in § 742/10(e), “6 or fewer dwelling units”. It is still worth reading the figure at source before relying on it, because an amending Public Act can change a number without changing anything else on this page.

Read as a machine, the section is a chain of six links: a qualifying repair, a cost within the threshold, a notice in a prescribed form and by a prescribed method, a wait, qualifying work by a qualifying person, and a proof step before the money moves. Every link has its own H2 below. A seventh element sits outside the chain: the tenant-fault bar in the final sentence, which can defeat the remedy however well the other six are executed.

The short title, at 765 ILCS 742/1, is worth knowing because it is what you search for: “This Act may be cited as the Residential Tenants’ Right to Repair Act.” If you are looking the Act up yourself, the citation form is 765 ILCS 742 for the Act and 765 ILCS 742/5 for the section that contains the remedy.

It is a test of whether you can use the Act at all. The two readings look similar and behave completely differently.

Grammatically, the threshold lives in the conditional clause of § 742/5. The sentence is built as: if a repair is required, and the reasonable cost does not exceed the lesser of $500 or one-half of the monthly rent, then the tenant may notify the landlord. The consequence attached to satisfying the condition is the right to give notice under the Act. Nothing in that sentence describes a deduction being trimmed to a maximum. The deduction sentence arrives much later, and when it does it repeats the limit by reference — “not to exceed the limits specified by this Section” — rather than introducing a new one.

Behaviourally, the difference is the difference between a discount and a door. If the limit were a cap, a tenant facing an expensive repair could commission the work and recover the capped amount, absorbing the excess. Because it is an entry test, a tenant facing an expensive repair has no statutory remedy under this Act at all: the notice does not start a statutory clock, the landlord’s silence does not authorise anything, and money taken off the rent is simply rent that was not paid. The landlord’s response to that is not a dispute about quantum. It is a claim for unpaid rent, with the eviction machinery behind it.

The second half of the correction is the word lesser. The threshold is the lower of $500 and one-half of the monthly rent — 765 ILCS 742/5. Those two numbers cross over at a rent of one thousand dollars a month. Above that crossover $500 is always the binding number and the rent fraction is irrelevant; below it the rent fraction binds and $500 never comes into play. So a tenant paying fourteen hundred dollars a month is limited by § 742/5 to $500, not to seven hundred; a tenant paying six hundred is limited to three hundred, not to $500. In practice that means the great majority of Illinois tenancies are governed by the fixed $500 limb of the § 742/5 test, and any guide that describes the limit purely as “half your monthly rent” is describing a remedy that is larger than the one the statute wrote, for most readers. The formulation used throughout this page is the statute’s own: 765 ILCS 742/5 makes it the lesser of $500 or one-half of the monthly rent.

What is being measured is also worth noting: the statute tests “the reasonable cost of the repair”, not the amount a particular contractor happened to charge. A quotation well above the market rate does not disqualify a repair whose reasonable cost is inside the threshold, and equally a cheap quotation does not bring an inherently expensive job inside it. That is why the letter should record the cost you are relying on: it shows the test was applied at the time of the notice, on a figure you can defend, rather than reconstructed afterwards.

765 ILCS 742/10 is captioned “Exceptions” and contains six subsections, each removing a category of property or tenancy from the Act entirely. If your situation is inside any one of them, the whole of the analysis above stops applying — not just the deduction, but the notice, the clock and the eviction defence too. In full, and in order:

(a) Public housing. The subsection provides that the Act “does not apply to public housing as defined in Section 3(b) of the United States Housing Act of 1937, as amended from time to time, and any successor Act.” Two things follow. The definition is federal, not Illinois’, so the question of whether a particular property is public housing is answered by federal law and by the definition that is current at the time, because the subsection expressly incorporates amendments and successor Acts. And the exclusion is drawn by the statutory category rather than by whether the tenant receives a subsidy, which are not the same question.

(b) Condominiums. “This Act does not apply to condominiums.” A tenant renting a condominium unit from its owner is outside the Act, even though the arrangement is in every other respect an ordinary residential tenancy. This one catches people out because a rented condominium looks nothing like an institutional exclusion; the subsection is nonetheless flat and unqualified.

(c) Residential cooperatives. The Act “does not apply to not-for-profit corporations organized for the purpose of residential cooperative housing.” Note both limbs: the entity must be a not-for-profit corporation, and it must be organised for that purpose. The subsection is describing a form of housing organisation, not any building that happens to be run collectively.

(d) Non-residential tenancies. “This Act does not apply to tenancies other than residential tenancies.” Consistent with the Act’s own short title, this is a residential statute end to end. A commercial or industrial tenancy has no access to it, and the repair obligations in a commercial lease are a matter of that lease.

(e) Owner-occupied property with 6 or fewer dwelling units. The subsection that does the most work and is misreported the most often. It is analysed in its own section below, because getting it right changes the answer for a very large number of Illinois renters.

(f) Mobile home units. The Act “does not apply to any dwelling unit that is subject to the Mobile Home Landlord and Tenant Rights Act.” The exclusion is drawn by reference to that separate statute’s coverage, so the question is whether the unit falls under it, and that statute’s own scope provisions answer it. This page did not verify that Act and states nothing about what it provides.

A practical note on order of operations: check § 742/10 before you check the cost threshold, and check both before you post anything. The exclusions are structural facts about the property that will not change between now and the end of the 14 days, so establishing them first saves a notice that could never have worked.

Yes. This is the single most consequential reading question in the Act, so here is the subsection again, complete: “This Act does not apply to owner-occupied rental property containing 6 or fewer dwelling units.”

The exclusion describes one thing: rental property that is owner-occupied and that contains 6 or fewer dwelling units. Both descriptors attach to the same property, and the property has to answer to both of them before the exclusion bites. There is no literal “and” in the sentence, and none is needed — that is simply how a restrictive noun phrase works in English. “A licensed insured contractor” means one person who is both licensed and insured, not a choice between two kinds of person.

The alternative reading collapses on its consequences. If “or” were meant, the subsection would exclude every rental property with 6 or fewer units whoever owns it, and separately every owner-occupied rental property of any size — between them most of the residential rental stock in the state, which would leave a remedy the legislature deliberately enacted applying to a fraction of tenants and make the careful drafting of the other five subsections pointless.

So the line runs like this. A six-flat where the owner lives in one of the flats is excluded. The same six-flat where the owner lives elsewhere is covered. A three-flat with an absentee owner is covered. A duplex where the owner lives on the other side is excluded. A twelve-unit building where the owner lives on site is covered, because it fails the unit-count half of the description. The owner’s residence in the building is the pivot; the unit count alone never is. Establish both facts — the unit count and whether the owner occupies one of them — before you write anything, because the entire remedy turns on the answer.

The trigger clause is broad, and this is where the Act is more generous than its money threshold suggests. A repair qualifies if it is “required under a residential lease agreement or required under a law, administrative rule, or local ordinance or regulation.” Four independent sources of obligation, any one of which is enough.

The lease. If the written agreement puts the repair on the landlord, that is the end of the enquiry for this element — no code violation is needed and no threshold of severity applies. Leases routinely allocate responsibility for appliances, heating plant, plumbing fixtures, windows and common areas, and a clause of that kind is exactly what the first limb is describing. Read the agreement before you assume you need to find a code.

A law. Statutory duties on landlords qualify. This page verified only 765 ILCS 742 and so does not attempt to catalogue Illinois’ other landlord duties; the point is structural, that a statutory obligation to repair is a qualifying source.

An administrative rule. Rules made under statutory authority sit alongside statutes in the list, so a duty created by regulation counts on the same footing.

A local ordinance or regulation. In practice this is the most productive limb for most tenants. Municipal building, property maintenance and housing codes are where concrete standards usually live — working heat, hot water at a stated temperature, functioning plumbing, weather tightness, safe electrical service — and a violation of one of those is a repair “required under … local ordinance or regulation”. Which code applies and what it demands is a matter of the municipality you are in, and this page publishes no municipal standard.

Notice what the trigger does not contain. There is no requirement that the condition threaten habitability, no requirement that it be dangerous, no requirement that an inspector certify it and no requirement that the tenant obtain any official finding first. Illinois’ Act is comparatively easy to trigger and comparatively hard to use, because the constraint is on money and procedure rather than on severity. A modest but genuinely required repair is exactly the fact pattern the Act was drafted for.

One qualification cuts the other way. The final sentence of § 742/5 bars the remedy where the condition “was caused by the deliberate or negligent act or omission of the tenant, a member of the tenant’s family, or another person on the premises with the tenant’s consent.” That is wider than tenant fault: it reaches the household and it reaches guests, and it covers negligence as well as deliberate acts. A condition caused by a visitor you let in is within it. Establish the cause honestly before you rely on the Act, because a landlord defending a deduction will look here first. Our wider guide to Illinois habitability laws sets the repair duty in its broader context.

By registered mail, certified mail, or another restricted delivery service. The statute does not merely require writing; it names methods. The clause reads that the tenant “may notify the landlord in writing by registered or certified mail or other restricted delivery service to the address of the landlord or an agent of the landlord as indicated on the lease agreement; if an address is not listed, the tenant may send notice to the landlord’s last known address of the tenant’s intention to have the repair made at the landlord’s expense.”

Take that clause apart, because it is doing four jobs at once.

The form: in writing. A telephone call, a conversation at the door or a message to a building manager is not the instrument this section describes, however clearly it communicated the problem.

The method: registered, certified, or other restricted delivery. The common feature of the named methods is that delivery is restricted and recorded, so both the fact and the date of delivery can be proved. That is the function the statute is protecting, and it is why hand delivery, ordinary first-class mail, email and text are not among the methods named. If you have been communicating with the landlord by email all year, keep doing so — but send the statutory notice by a named method as well, and keep the receipt.

The address: the lease first, last known address second. The primary address is the one shown on the lease for the landlord or the landlord’s agent. The fallback applies only “if an address is not listed”. Do not treat the fallback as a free choice: if the lease gives an address, that is the address, even if you believe the landlord is more likely to read something sent somewhere else.

The content: an intention, not a request. What is being notified is “the tenant’s intention to have the repair made at the landlord’s expense.” A letter that describes a defect and asks for it to be fixed has not notified that intention. This is the most common defect in tenant letters and it is invisible until the deduction is challenged, because a repair request and a statutory notice look alike to everyone except the statute. Say it in terms: that you intend to have the repair made and to deduct the cost from the rent as 765 ILCS 742/5 permits.

14 days. The tenant may proceed if the landlord “fails to make the repair within 14 days after being notified by the tenant as provided above or more promptly as conditions require in the case of an emergency.”

Three details. First, the clock runs from notification, which is why the delivery record matters: the date you posted the letter and the date the landlord was notified are not necessarily the same date, and the statute measures from the latter. Second, the phrase “as provided above” ties the clock to a notice that complied with the delivery and content requirements — a defective notice does not start a valid 14 days, however long ago it was sent. Third, what ends the landlord’s period is making the repair, not responding to the letter. A landlord who writes back promising to attend and does nothing has not made the repair, and the fourteenth day arrives on schedule.

The emergency limb is a standard rather than a shorter fixed period. The Act does not say “48 hours” or “three days” for emergencies; it substitutes “more promptly as conditions require”, which means the permissible wait is whatever the condition itself dictates. That is deliberately flexible and it cuts both ways: it lets a tenant act quickly where waiting would be absurd, and it leaves the tenant to justify the compression afterwards.

The Act does define the category. “Emergencies include conditions that will cause irreparable harm to the apartment or any fixture attached to the apartment if not immediately repaired or any condition that poses an immediate threat to the health or safety of any occupant of the dwelling or any common area.” Two branches, then. One is property-directed: irreparable harm to the apartment or an attached fixture, if not repaired immediately. The other is person-directed: an immediate threat to health or safety, and note how far it reaches — to any occupant of the dwelling, and to conditions in any common area, not only inside the tenant’s own unit. Note also the word “include”: the definition is illustrative rather than exhaustive, so it sets out what certainly qualifies without closing the category.

765 ILCS 742/15 is captioned “Tenant liabilities and responsibilities” and it is where most of the risk in this remedy actually sits. In full:

“The tenant is responsible for ensuring that: (1) the repairs are performed in a workmanlike manner in compliance with the appropriate law, administrative rule, or local ordinance or regulation; (2) the tradesman or supplier that is hired by the tenant to perform the repairs holds the appropriate valid license or certificate required by State or municipal law to make the repair; and (3) the tradesman or supplier is adequately insured to cover any bodily harm or property damage that is caused by the negligence or substandard performance of the repairs by the tradesman or supplier. The tenant is responsible for any damages to the premises caused by a tradesman or supplier hired by the tenant. A tenant shall not be entitled to exercise the remedies provided for in this Act if the tenant does not comply with the requirements of this Section.”

Read that as four obligations and one sanction.

Workmanlike and compliant. The standard applies to the work itself, and the compliance limb points at the same sources as the trigger clause: law, administrative rule, local ordinance or regulation. Work that would itself violate a code is not work that satisfies § 742/15(1), and a repair done to a lower standard than the code requires can turn a remedy into a liability.

Licensed. The tradesman must hold “the appropriate valid license or certificate required by State or municipal law to make the repair”. Note the conditional: the requirement bites where a licence is required for that kind of work, which in practice means trades such as electrical and plumbing work are the ones to check first, and that municipal licensing counts alongside State licensing. Ask for the licence number before the work is booked, not after.

Adequately insured. The insurance must cover bodily harm or property damage caused by the tradesman’s negligence or substandard performance. A certificate of insurance is the ordinary proof and is not an unusual thing for a contractor to be asked for.

Unrelated to the tenant. This one comes from § 742/5 rather than § 742/15, but it belongs in the same list: the deduction follows a paid bill “from an appropriate tradesman or supplier unrelated to the tenant.” Illinois does not permit the tenant to do the work and bill for their own labour, and a bill from a relative is precisely what the words exclude. If you have the skills and the tools, the statute still wants a third party’s invoice.

The tenant carries the damage. “The tenant is responsible for any damages to the premises caused by a tradesman or supplier hired by the tenant.” That is an unqualified allocation of risk. If your plumber floods the flat below, the exposure is yours, which is exactly why subsection (3) insists on insurance and why you should verify it rather than take it on trust.

The sanction. The final sentence is absolute: a tenant who does not comply with § 742/15 “shall not be entitled to exercise the remedies provided for in this Act.” Not a reduced remedy. No remedy. Hiring an unlicensed tradesman for work that requires a licence can therefore cost a tenant the entire deduction even though the repair was necessary, the notice was perfect and the work was good.

The Act’s proof step is a precondition, and its wording is precise: “After submitting to the landlord a paid bill from an appropriate tradesman or supplier unrelated to the tenant, the tenant may deduct from his or her rent the amount of the bill, not to exceed the limits specified by this Section and not to exceed the reasonable price then customarily charged for the repair.”

The bill must be paid. The tenant fronts the cost and recovers it through the rent afterwards. An unpaid invoice is not what the section describes, so a tenant who arranges work on terms and tries to pass the invoice to the landlord has not performed this step.

Submission comes first. The word is “after”. Submitting the bill is the event that unlocks the deduction, not a courtesy that follows it. A tenant who withholds first and sends paperwork later has done the two steps in the order the statute does not allow.

Identify the tradesman if the bill does not. “If not clearly indicated on the bill submitted by the tenant, the tenant shall also provide to the landlord in writing, at the time of the submission of the bill, the name, address, and telephone number for the tradesman or supplier that provided the repair services.” Three specified particulars, in writing, at the same time. The purpose is obvious: the landlord is being asked to fund work they did not commission and is entitled to be able to contact whoever did it. The simplest compliance is a covering letter carrying all three details whether or not the invoice shows them.

Two separate ceilings apply to the amount. The first is the § 742/5 threshold itself, imported by reference. The second is independent and easy to overlook: the deduction may not exceed “the reasonable price then customarily charged for the repair.” So even a paid bill inside the threshold can be excessive if the tradesman charged well above the customary rate, and the excess is not deductible. Getting a second quotation before the work is booked is cheap protection against that, and it also gives you a contemporaneous record of what the customary price was.

Finally, deduct visibly. When the rent goes across, say in writing what was deducted, for what, and by reference to the bill already submitted. A silent short payment reads as a missed payment, and the distinction between the two is the whole of the argument if it ever becomes one.

The Act answers this twice, and both answers are severe.

765 ILCS 742/15 closes with: “A tenant shall not be entitled to exercise the remedies provided for in this Act if the tenant does not comply with the requirements of this Section.”

765 ILCS 742/20, captioned “Defense to eviction”, provides: “A tenant may not assert as a defense to an action for rent or eviction that rent was withheld under this Act unless the tenant meets all the requirements provided for in this Act.”

Read them together and the architecture is clear. Section 15 removes the remedy for failure to meet that section’s requirements. Section 20 goes further and removes the defence unless the tenant meets “all the requirements provided for in this Act” — the whole Act, not one section. So a tenant who satisfied § 742/15 perfectly but sent the notice by first-class mail has still not met all the requirements, and § 742/20 is what they will run into when the landlord files.

The consequences of a defective attempt are not proportional to the defect: what the Act gives, in exchange for exacting compliance, is the right to answer a claim for unpaid rent, and what it withholds from imperfect compliance is that same right. One further consequence follows from § 742/20’s wording — because it speaks to “an action for rent or eviction”, compliance matters even where possession is not at stake. Our guide to Illinois eviction notice laws explains what the landlord’s side of that process looks like.

765 ILCS 742/30, captioned “Home rule”, provides: “A home rule unit may not regulate residential lease agreements in a manner that diminishes the rights of tenants under this Act. This Section is a limitation under subsection (i) of Section 6 of Article VII of the Illinois Constitution on the concurrent exercise by home rule units of powers and functions exercised by the State.”

The operative word is diminishes. Section 30 is a floor, not a ceiling. A home rule municipality may not legislate tenants below the protection this Act gives them; the section says nothing at all about a municipality that chooses to give more. So the correct general statement is that the Act sets a statewide minimum and a local ordinance may sit above it.

So the check is two-step: the Act as described on this page, then whatever your own municipality has enacted, which may provide a different procedure, threshold or notice period. No ordinance was verified for this page, so no ordinance figure, deadline or procedure appears anywhere on it — publishing an ordinance threshold we had not read would be exactly the kind of plausible, unverified number that sends a reader to the wrong step. Municipal clerks and local legal aid organisations are the usual routes to an authoritative copy. And note the converse of § 742/30: if a local rule appears to give you less than 765 ILCS 742 does, the home rule limitation is the provision to raise.

765 ILCS 742/25 is a short section with a real-world consequence that neither party usually anticipates: “For purposes of mechanics lien laws, repairs performed or materials furnished pursuant to this Act shall not be construed as having been performed or furnished pursuant to authority of or with permission of the landlord.”

Mechanics lien law generally allows a contractor who improves real property with the owner’s authority or permission to assert a claim against the property itself if they are not paid. Section 25 closes that door for work done under this Act. The statute deems the work not to have been performed with the landlord’s authority or permission for lien purposes — which is coherent, because the whole premise of the remedy is that the tenant commissioned the work precisely because the landlord did not.

Two practical consequences. For the tenant, it is a reminder of where the money sits: you pay the tradesman, and your route to recovery is the rent deduction, not a claim the tradesman might otherwise have had against the building. For the tradesman, it is a reason to be paid in the ordinary way and on ordinary terms, because the property is not standing behind the invoice. If you tell a contractor the work is being done under 765 ILCS 742, telling them about § 742/25 as well is straightforward courtesy and avoids a misunderstanding later.

Plenty of Illinois tenants will read the two tests above and find they are outside the Act: the building is owner-occupied and small, the unit is a condominium, the tenancy is not residential, or the repair simply costs more than $500 or one-half of the monthly rent, whichever is lower. The honest answer is that 765 ILCS 742 then gives you nothing, and the single worst response is to use it anyway. A deduction taken without a statutory footing is unpaid rent, and § 742/20 will not help you defend it.

What remains is not nothing, but it is different in kind, and this page is careful about what it asserts. Only 765 ILCS 742 was verified for this page, so what follows is described as practical routes rather than as statements of Illinois law.

Put the problem in writing anyway. A dated, specific written record of the condition, sent by a method that proves delivery, is useful in every route that follows and costs you nothing. It is also the document that most often produces the repair without anything further, because it changes the landlord’s own risk calculation.

Ask the municipality to inspect. Where a local code applies, a code enforcement complaint puts an official finding behind the tenant’s description of the problem. That is valuable independently of this Act, and it is one of the few steps a tenant can take that produces evidence they did not write themselves.

Ask for a written agreement to the deduction. Nothing prevents a landlord and a tenant agreeing that the tenant will arrange a repair and set the cost against rent. Outside the Act, that arrangement is contractual, so it lives or dies on being recorded — the scope of the work, the cost, and the rent period it comes off. Get it in writing before the work is booked.

Take advice before withholding anything. Rent withholding, escrow arrangements, damages claims and lease termination all raise questions this page did not verify and all carry real downside if they are misjudged. Illinois legal aid organisations and local tenant advice services exist for exactly this, and a short conversation before a deduction is worth a great deal more than a long one after it. For the surrounding rules, our overview of Illinois landlord tenant laws is the place to start.

The letter is a statutory clock starting, and the landlord’s checks are the tenant’s steps read in reverse: § 742/10 coverage first, then the entry test, then whether the notice itself was in writing, sent by a named restricted-delivery method to the right address, and stated an intention to have the repair made at the landlord’s expense. What stops the clock is making the repair, not answering the letter — and where the repair is one the landlord is obliged to make, making it is almost always cheaper than the argument and forecloses the deduction entirely. One point deserves naming on this side specifically: an absentee-owned small building is inside the Act, and asserting otherwise is the mirror image of the tenant error described above. Keeping a current notice address in the lease is the cheapest preventive step of all, since it is where the statute sends the notice in the first place. Our guide to Illinois landlord entry laws covers access for the repair itself.

The statutory text quoted above was read on the Illinois General Assembly’s own site, ilga.gov, and cross-checked against a Wayback Machine capture of the same official page taken before the site’s redesign. The operative wording is identical on both. That cross-check proves the text survived the site redesign unchanged; it is not independent editorial corroboration, because both copies come from the same publisher. Three commercial statute publishers were attempted as a genuinely independent second source and returned bot-blocks for every request, so none of them is named here.

Two cautions belong with that. The Illinois General Assembly’s own database carries a warning that recent laws may not yet be included, so a very recent amendment may not be reflected; the $500 figure in § 742/5 in particular is printed here as the Act printed it when it was read for this page, and a figure is exactly the kind of thing an amending Public Act can move, so check it at source before relying on it. And the whole of 765 ILCS 742 runs to well under a thousand words, which is too small a body of text to support a negative claim about Illinois law generally.

So this page states what the Act says and stops there. The Act does not address the frequency with which the remedy may be used, does not address retaliation, does not address security deposits and does not address rent increases — but no other Illinois instrument was fetched for this page, so nothing here should be read as saying that Illinois law is silent on those subjects. It is not, and this page simply did not verify them. Nor was any municipal ordinance read, which is why no local threshold or procedure appears above. Where those questions matter to you, they are separate research, and the sensible order is to settle the Act first, because it is the only part answered here.

Three neighbouring questions are decided under different rules and are worth keeping separate from this one: the notice that ends a tenancy (Illinois eviction notice laws), what a landlord may keep out of a deposit and by when it must come back (Illinois security deposit laws), and the exposure a tenant takes on by leaving early (breaking a lease in Illinois).
