Free Illinois Repair and Deduct Letter

Illinois gives tenants a narrow statutory repair-and-deduct remedy under the Residential Tenants’ Right to Repair Act, 765 ILCS 742. The cost limit decides whether you may use the Act at all, the notice has to go by registered or certified mail or another restricted delivery service, and the landlord then has 14 days.

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 exclusion in § 742/10(e) is conjunctive, and most summaries get it backwards

765 ILCS 742/10(e) reads, in its entirety: “This Act does not apply to owner-occupied rental property containing 6 or fewer dwelling units.” That is one restrictive phrase describing one kind of property, and it takes both features to match it. The property has to be owner-occupied, and it has to contain 6 or fewer dwelling units. So: a four-unit building whose owner lives across town is covered by the Act. The identical four-unit building whose owner lives in unit one is not. The owner’s own residence is the pivot, not the unit count on its own. The grammar of the subsection, and what follows if it is read as though it said “or”, are worked through in full further down this page.

Illinois repair and deduct remedy at a glance

Does Illinois have repair and deduct

Yes, but narrowly — 765 ILCS 742/5

The cost limit is an ENTRY TEST, not a cap

If the reasonable cost exceeds $500 or one-half of the monthly rent, whichever is lower — 765 ILCS 742/5 — the Act is not available at all

The clock

14 days after the landlord is notified — or sooner if the condition is an emergency as § 742/5 defines it

Who is excluded by § 742/10(e)

Property that is owner-occupied AND has 6 or fewer dwelling units. Small building, absentee owner: still covered

Illinois note: Cells two and four are the two facts competing guides get wrong, and both are analysed below. The threshold in 765 ILCS 742/5 is the lesser of $500 or one-half of the monthly rent — so on any rent above one thousand dollars a month the $500 limb is the lower of the two and governs.

How the Illinois repair-and-deduct procedure runs

The five-step sequence

Check that the Act reaches you, and that the cost clears the entry test

§ 742/10 removes six categories, including property that is both owner-occupied and has 6 or fewer dwelling units. Then apply the § 742/5 entry test: the reasonable cost of the repair must not exceed $500 or one-half of the monthly rent, whichever is lower. Fail either check and the Act is not your route.

Send the notice by registered or certified mail or another restricted delivery service

§ 742/5 names the delivery method, not merely writing. Address it as the lease indicates for the landlord or the landlord’s agent; if the lease lists no address, use the landlord’s last known address. The notice must state the tenant’s intention to have the repair made at the landlord’s expense.

Wait 14 days, or move faster if the statute’s emergency definition is met

The tenant may proceed if the landlord “fails to make the repair within 14 days after being notified … or more promptly as conditions require in the case of an emergency.” The Act sets no shorter fixed emergency clock; it substitutes a standard for the 14 days.

Have a licensed, insured tradesman unrelated to you do the work

§ 742/15 makes the tenant responsible for ensuring the work is workmanlike and compliant, that the tradesman holds any licence State or municipal law requires, and that the tradesman is adequately insured. § 742/5 requires the tradesman or supplier to be unrelated to the tenant, so your own labour does not produce a deductible bill.

Pay the bill, submit it to the landlord, and only then deduct

The deduction follows “after submitting to the landlord a paid bill.” Add the tradesman’s name, address and telephone number in writing if the bill does not show them clearly. The amount is limited by § 742/5 and separately by “the reasonable price then customarily charged for the repair.”

About the Illinois repair and deduct letter

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.

What an Illinois repair-and-deduct letter should record

  • 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.

Common Illinois repair and deduct mistakes

  • 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.

Does Illinois have a repair and deduct law?

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.

What does 765 ILCS 742/5 actually say?

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
