Illinois Residential Lease Agreement Template

An Illinois residential lease is shaped as much by local ordinance as by state law — Chicago's Residential Landlord and Tenant Ordinance and Cook County's equivalent impose obligations that go well beyond the Illinois statutes. Confirm which ordinance covers your address before you sign.

What Is a Illinois Residential Lease Agreement?

Illinois state law sets a relatively modest baseline for residential tenancies, but the practical rules in much of the state come from local ordinances. The Chicago Residential Landlord and Tenant Ordinance is one of the most detailed municipal rental codes in the country, requiring a summary of the ordinance to be attached to every lease, mandating interest on security deposits at a city-published rate, and imposing short deposit return deadlines with significant penalties. Cook County adopted a similar ordinance covering much of the suburban area, and Evanston and other municipalities have their own. At the state level, Illinois requires deposit interest for larger buildings, regulates deposit return with itemization and receipts, and prohibits retaliatory conduct and lockouts. Illinois also preempts local rent control by statute, so rent increases are governed by the lease and notice rules rather than by a cap. Landlord obligations around radon and lead in the state's older housing stock deserve specific attention.

A residential lease agreement is a written contract in which a landlord grants a tenant the right to occupy a specific residential property for a fixed period in exchange for rent. It records the details that disputes are usually fought over: how much rent is due and when, how long the tenancy lasts, how large the security deposit is, who pays which utilities, and what each side must do to keep the property in livable condition.

When to Use This Template

  • You are renting out a house, apartment, condo, or duplex for a fixed term such as six or twelve months.

Illinois Residential Lease Agreement

  1. 1. 1. Parties

    This Residential Lease Agreement (the "Agreement") is entered into on [AGREEMENT DATE] between [LANDLORD NAME], with a notice address at [LANDLORD ADDRESS] ("Landlord"), and [TENANT NAME] ("Tenant"). Landlord and Tenant are each referred to as a "Party" and together as the "Parties." Every adult who will occupy the property must sign this Agreement, and each signer is jointly and severally liable for all obligations under it. Notices are effective when delivered in person, sent by certified mail, or emailed to [LANDLORD EMAIL] or [TENANT EMAIL].

  2. 2. 2. Premises

    Landlord leases to Tenant the residential property located at [PROPERTY ADDRESS], together with [PARKING SPACE / STORAGE UNIT / OTHER INCLUDED AREAS] (the "Premises"). The Premises are rented as [FURNISHED / UNFURNISHED / PARTIALLY FURNISHED] and include the appliances listed on the move-in checklist attached as Exhibit A. Tenant has inspected the Premises and accepts them in their present condition except for the items noted on that checklist. No more than [MAXIMUM OCCUPANTS] people may occupy the Premises without prior written consent from Landlord.

  3. 3. 3. Term

    The initial term of this Agreement begins on [START DATE] and ends at 11:59 p.m. on [END DATE] (the "Term"). Either Party may give written notice of intent not to renew at least [RENEWAL NOTICE DAYS] days before the end date. If Tenant remains in the Premises after the Term with the written consent of Landlord, the tenancy converts to a month-to-month tenancy on the same terms, except that rent may be adjusted on [RENT CHANGE NOTICE DAYS] days written notice. If Tenant remains without consent, Tenant owes holdover rent of [HOLDOVER DAILY RENT] per day plus any damages Landlord incurs.

  4. 4. 4. Rent

    Tenant agrees to pay rent of [MONTHLY RENT] per month, due in advance on the [RENT DUE DAY] day of each month without demand, offset, or deduction. Payment must be made by [PAYMENT METHOD] to [PAYEE NAME AND PAYMENT ADDRESS OR ACCOUNT]. If rent is not received within [GRACE PERIOD DAYS] days after the due date, Tenant owes a late fee of [LATE FEE AMOUNT], and any payment returned unpaid carries a fee of [RETURNED PAYMENT FEE]. Rent for a partial first or final month is prorated on a daily basis. Late fees are treated as additional rent, and accepting a late or partial payment does not waive any right of Landlord.

  5. 5. 5. Security Deposit

    On signing this Agreement, Tenant will deliver [SECURITY DEPOSIT AMOUNT] to Landlord as security for performance of the obligations of Tenant (the "Deposit"). The Deposit is not prepaid rent and may not be applied by Tenant toward the final month of the Term. Landlord may apply the Deposit to unpaid rent, unpaid utilities, cleaning beyond normal wear and tear, and damage caused by Tenant, occupants, or guests. Within [DEPOSIT RETURN DAYS] days after Tenant surrenders the Premises, Landlord will return any unused portion together with an itemized statement of deductions, sent to the forwarding address supplied by Tenant. Landlord will hold and return the Deposit in the manner and within the time limits required by applicable law.

  6. 6. 6. Utilities and Services

    Tenant is responsible for arranging and paying for the following: [TENANT-PAID UTILITIES, E.G. ELECTRICITY, GAS, INTERNET]. Landlord is responsible for [LANDLORD-PAID UTILITIES, E.G. WATER, SEWER, TRASH]. Tenant must open accounts for tenant-paid utilities in the name of Tenant on or before the start of the Term and keep them active until the Premises are surrendered. An interruption caused by a utility provider or by circumstances outside the reasonable control of Landlord does not entitle Tenant to withhold rent, but Landlord will act promptly to restore any service that Landlord controls.

  7. 7. 7. Use and Occupancy

    The Premises may be used only as a private residence by Tenant and the occupants named in this Agreement. Tenant may not use the Premises for any unlawful purpose or operate a business that draws customer traffic to the property. Tenant agrees not to create noise or conduct that unreasonably disturbs neighbors and to follow any community, condominium, or homeowners association rules that Landlord provides in writing. A guest may stay no longer than [GUEST STAY LIMIT DAYS] consecutive days without written consent from Landlord.

  8. 8. 8. Pets

    No animal may be kept on the Premises except as expressly permitted here: [PERMITTED PETS, INCLUDING TYPE, BREED, AND WEIGHT LIMITS]. If pets are permitted, Tenant will pay a pet deposit of [PET DEPOSIT AMOUNT] and monthly pet rent of [PET RENT AMOUNT], and remains fully liable for any damage, odor, or pest treatment caused by the animal. Tenant will keep animals leashed or contained in common areas and will remove waste promptly. This section does not apply to assistance animals that Landlord is required to accommodate under applicable law.

  9. 9. 9. Maintenance, Repairs, and Alterations

    Landlord will maintain the structure, roof, plumbing, electrical system, heating, and any appliances supplied by Landlord in safe and working order. Tenant will keep the Premises clean and sanitary, dispose of trash properly, avoid damage beyond normal wear and tear, and notify Landlord in writing as soon as a repair, leak, or unsafe condition appears. Tenant is responsible for the cost of repairs caused by the negligence or misuse of Tenant, occupants, or guests, including drain blockages and broken glass. Tenant may not paint, install fixtures, change locks, or make alterations without prior written consent from Landlord, and any approved alteration becomes part of the Premises unless Landlord requires its removal at the end of the Term. Tenant will keep smoke and carbon monoxide detectors in working order and will not disable them.

  10. 10. 10. Landlord Right of Entry

    Landlord may enter the Premises to inspect the property, make repairs, supply agreed services, or show the unit to prospective tenants, buyers, lenders, or contractors. Except in an emergency, Landlord will give Tenant at least [ENTRY NOTICE HOURS] hours advance notice and will enter only at reasonable times of day. In an emergency involving risk to persons or property, or where the Premises appear to have been abandoned, Landlord may enter without notice. Landlord will not use the right of entry to harass Tenant or to enter repeatedly without a legitimate purpose.

  11. 11. 11. Assignment and Subletting

    Tenant may not assign this Agreement, sublet all or part of the Premises, or list the Premises on a short-term rental platform without prior written consent from Landlord. Landlord will not unreasonably withhold consent but may require a written request, screening of the proposed occupant, and a signed sublease that incorporates this Agreement. Any assignment or sublease made without consent is void and is a material breach. Even where consent is granted, Tenant remains fully liable for rent and damage unless Landlord releases Tenant in writing.

  12. 12. 12. Default and Remedies

    Tenant is in default if rent is not paid when due, if Tenant breaches any other obligation and fails to cure it within [CURE PERIOD DAYS] days after written notice, or if Tenant abandons the Premises. On default, Landlord may pursue any remedy available under applicable law, including ending the tenancy, recovering possession, and recovering unpaid rent, late fees, and damages. Landlord will make reasonable efforts to re-rent the Premises and will credit rent actually collected against amounts owed by Tenant. The prevailing Party in any action to enforce this Agreement may recover reasonable attorney fees and costs to the extent permitted by law.

  13. 13. 13. Termination and Surrender

    This Agreement ends on the last day of the Term unless renewed in writing or converted to a month-to-month tenancy as described above. On or before the end date, Tenant will remove all personal property, return every key, remote, and access device, and leave the Premises clean and in the same condition as at move-in, excepting normal wear and tear. Tenant will give Landlord a written forwarding address so the deposit statement can be delivered. Early termination by Tenant requires [EARLY TERMINATION NOTICE DAYS] days written notice and payment of an early termination fee of [EARLY TERMINATION FEE], where such a fee is permitted by law. Personal property left behind after surrender may be handled by Landlord as applicable law allows, and Tenant may be charged for removal and storage.

  14. 14. 14. Governing Law

    This Agreement is governed by the laws of the state where the Premises are located, without regard to conflict of law rules. If any provision conflicts with a mandatory landlord-tenant statute or local ordinance, that statute or ordinance controls and the rest of the Agreement remains in effect. The Parties agree that any dispute will be brought in a court of competent jurisdiction in [COUNTY AND STATE]. Nothing in this Agreement waives a right that applicable law does not permit to be waived.

  15. 15. 15. Entire Agreement

    This Agreement, together with any exhibits and written addenda signed by both Parties, is the entire agreement between Landlord and Tenant and replaces all prior listings, emails, discussions, and promises about the Premises. No change is effective unless it is in writing and signed by both Parties. If a court finds any provision unenforceable, the remaining provisions stay in full force. A failure by either Party to enforce a provision on one occasion is not a waiver of that provision on any other occasion.

  16. 16. 16. Signatures

    The Parties have read this Agreement, understand it, and agree to be bound by it as of the dates written below. Landlord signature: ____________________ Print name: [LANDLORD NAME] Date: [DATE] Tenant signature: ____________________ Print name: [TENANT NAME] Date: [DATE] Additional tenant signature: ____________________ Print name: [ADDITIONAL TENANT NAME] Date: [DATE]

  17. 17. Illinois Landlord-Tenant Highlights

    Illinois state law does not impose a general statewide cap on security deposits, but it requires landlords of larger buildings to pay interest on deposits at a state-set rate and requires an itemized statement with paid receipts or estimates before deductions can be taken, commonly within [NUMBER] days after move-out, with the balance returned within a further statutory period. In Chicago and much of Cook County, local ordinances impose stricter deposit rules including city-published interest rates, short return deadlines, and damages for violations, so identify the governing ordinance before drafting. Illinois requires reasonable notice before entry and entry at reasonable times, and Chicago's ordinance sets a specific notice standard, commonly two days, with emergencies excepted. Illinois prohibits retaliatory eviction and self-help lockouts, and it preempts local rent control, so there is no rent cap anywhere in the state. Federal lead-based paint rules apply broadly given Illinois's older housing stock, and the state adds radon and, in some jurisdictions, bed bug disclosure obligations.

  18. 18. Required Disclosures in Illinois

    Illinois requires a radon disclosure for residential rentals where the landlord has knowledge of elevated radon levels or a radon hazard, along with the state radon pamphlet in defined circumstances. Federal law requires the lead-based paint disclosure, records of known hazards, and the EPA pamphlet for any dwelling built before 1978, which covers a large share of Illinois housing. Chicago requires a summary of the Residential Landlord and Tenant Ordinance to be attached to every covered lease, plus a separate bed bug information brochure, and Cook County requires a similar ordinance summary for covered properties. Landlords must disclose the owner or authorized agent for notices, and any utility arrangement where a tenant is billed for service that also covers common areas requires specific written disclosure. Verify state requirements with the Illinois General Assembly and check your municipality separately.

  19. 19. Illinois Official Resources

    For current statutes and official guidance, consult the Illinois General Assembly (Illinois Compiled Statutes) (https://www.ilga.gov). State law changes — verify any deadline, cap, or disclosure requirement against the current official text before relying on it.

Key Clauses Explained

What each important clause does — and what to watch out for before you sign.

Rent and Late Fees

Fixes the monthly amount, the due date, the accepted payment method, and what happens when a payment is late or returned unpaid.

Watch for a grace period of zero days combined with a flat late fee that hits on day one, and for language that stacks a daily fee on top of the flat fee. Also check that the payment method is one you can actually use every month, because a lease that only accepts a portal with a processing charge quietly raises your rent.

Security Deposit

Sets the deposit amount, the permitted deductions, and the deadline for returning the balance with an itemized statement.

Watch for open-ended deduction language such as cleaning and repainting on move-out, which turns routine wear into a charge against your money. Insist on a written move-in condition checklist with photos, and confirm the return deadline matches what your state requires rather than a longer window written into the form.

Term and Renewal

States the start and end dates and what happens when the term runs out, including automatic conversion to month-to-month.

Watch for automatic renewal that locks you into another full year unless you give notice months in advance. Put the notice deadline in your calendar the day you sign, and confirm whether holdover rent applies at a penalty rate if you stay even a few days past the end date.

Maintenance and Repairs

Splits responsibility between the structural and system repairs owed by the landlord and the day-to-day upkeep owed by the tenant.

Watch for clauses that push appliance replacement, HVAC servicing, or a fixed repair deductible onto you. Anything phrased as tenant is responsible for all repairs under a dollar amount can add up fast, and a clause requiring you to waive habitability rights is a red flag.

Landlord Right of Entry

Defines when and how the landlord may come into the home, and the advance notice required outside emergencies.

Watch for entry at any reasonable time with no stated notice period, or a broad emergency definition that swallows the rule. If the landlord plans to show the unit during your final months, ask for a fixed notice window and limits on showing hours before you sign.

Early Termination

Explains the notice and fee required if the tenant needs to leave before the term ends.

Watch for a clause making you liable for rent through the end of the term with no duty for the landlord to re-rent. A reasonable version caps your exposure at one to two months and confirms the landlord will actively look for a replacement tenant.

Joint and Several Liability

Makes each adult signer responsible for the entire rent, not just a personal share.

Watch for this when you are signing with people you do not know well, because if a co-tenant stops paying the landlord can pursue you for the full amount. A separate roommate agreement will not change what the landlord can collect, so only sign jointly with people you trust.

Assignment and Subletting

Controls whether the tenant can hand the lease to someone else or rent out part of the property.

Watch for an absolute ban with no consent standard, which removes your exit if your job or family situation changes. Ask for language saying consent will not be unreasonably withheld, and confirm short-term rental listings are addressed explicitly if that matters to you.

Frequently Asked Questions

Is there a security deposit limit in Illinois?
Illinois does not impose a general statewide cap on the deposit amount, but it heavily regulates handling and return, including required interest for larger buildings and an itemized statement with receipts before any deduction. Chicago and Cook County ordinances add stricter caps on timing, city-published interest rates, and meaningful damages for violations. Identify the ordinance that covers your address before setting the deposit, because the local rule usually controls.
How much notice must an Illinois landlord give to enter or to end a tenancy?
Illinois requires reasonable notice at a reasonable time for non-emergency entry, and Chicago's ordinance sets a specific standard commonly stated as two days. To end a month-to-month tenancy, written notice must be given a statutory period before the next rent date, and Chicago imposes longer notice for nonrenewal that scales with how long the tenant has occupied the unit. Confirm both the state figure and any local ordinance before serving notice.
Does a lease need to be notarized in Illinois?
No. An Illinois residential lease is enforceable once signed by the landlord and each adult tenant, and notarization is not required. Leases longer than one year must be in writing, and Chicago requires the ordinance summary to be attached — a far more consequential formality than notarization.
Does the Chicago RLTO apply to my rental?
The Chicago Residential Landlord and Tenant Ordinance covers most rental units within city limits, with recognized exemptions for owner-occupied buildings with a small number of units, hotels, and certain other arrangements. Where it applies, the landlord must attach the official ordinance summary to the lease, pay deposit interest at the city-published rate, and meet short deposit return deadlines with real penalties for noncompliance. Suburban Cook County has a comparable ordinance, so check both the city and county rules for your address.
Is a residential lease agreement legally binding?
Yes. Once both the landlord and the tenant sign, a residential lease is an enforceable contract in every US state. It becomes binding on signature and delivery, not on any government filing. A lease can even be oral in many states, but an oral lease is far harder to prove and most states require a writing for terms longer than one year.
Does a lease agreement need to be notarized?
Almost never. Standard residential leases of one year or less are valid with just the signatures of the parties. A handful of states require notarization or recording for long-term leases, typically those running several years, so check local rules if your term is unusually long. Notarizing is optional otherwise and simply adds proof that the signatures are genuine.
