Subletting Laws and Permissions for Illinois Renters

Thinking about subletting your apartment in Illinois? Understanding your legal rights and the specific rules around subleasing is essential before listing your place or accepting a new roommate. This article explains Illinois subletting laws, permission requirements, and your options—with steps, helpful tips, and links to government resources.

What Is Subletting and Is It Allowed in Illinois?

Subletting means that an original tenant (the "sublessor") rents out their unit, or part of it, to another person (the "sublessee") while remaining legally responsible under the original lease. In Illinois, subletting is generally permitted unless your lease specifically forbids it. It’s important to check your lease agreement for a sublet clause—some landlords require you to get written permission before subletting, while others may prohibit it altogether.

Key Facts About Subletting in Illinois

• No statewide law automatically allows subletting: Illinois law defers to your lease agreement's terms.
• Landlord permission may be required: Many leases have a clause that prohibits or restricts subleases.
• Written approval is safest: Even if your lease is silent, notify your landlord and seek written consent for transparency and protection.

What the Law Says: Illinois Lease and Subletting Legislation

Illinois residential tenant rights and duties, including subletting and shared housing, fall under the Illinois Compiled Statutes – Landlord and Tenant Act (765 ILCS 705) and the Illinois Security Deposit Return Act (765 ILCS 710). For renters in Chicago, the Chicago Residential Landlord and Tenant Ordinance (RLTO) also applies.^[1][2][3]

Common Lease Clauses About Subletting

• Permission required: Many Illinois leases require landlord written approval to sublet.
• Prohibited: Some leases explicitly ban subletting. Violating this can lead to lease termination.
• No mention: If your lease is silent, communicate your request in writing and keep records.

If unsure, ask your landlord or review your lease carefully. Always keep written documentation of any permissions or restrictions.

How to Legally Sublet Your Rental in Illinois: Step-By-Step Guide

If your lease allows subletting (or doesn’t mention it), here's how to approach it safely and legally:

• Read your lease thoroughly for terms around subletting.
• Draft a written sublet request to your landlord, including proposed dates and the new occupant’s details.
• Wait for your landlord’s response—written approval is best.
• If approved, create a sublease agreement (preferably in writing).
• Share all rules, rent terms, and expectations with your subtenant.

Official Forms Related to Subletting

There is no statewide “sublet request” form mandated by Illinois. Instead:

• Written Lease Assignment or Sublease Agreement: Used when subletting with landlord approval. You or your landlord may draft this; be sure to include all obligations from your original lease. For a template, you can review the sample Chicago Sublease Agreement (Sample PDF).
• Written Landlord Approval (Letter or Email): It's recommended to request this in writing and keep a copy for your records.

If a dispute arises, contact your local city or county housing department or the relevant tribunal or court. In Illinois, small claims court often handles such disputes.

Who Handles Rental Disputes in Illinois?

The Illinois Circuit Courts handle landlord-tenant disputes, including issues with subletting, eviction, and lease enforcement.^[4] If you are in Chicago, you may also consult the Chicago Department of Housing for city-specific help.^[5]

Your Subtenant's Rights and Responsibilities

If you sublet to someone else, you are still responsible for rent payments and any lease violations unless the landlord releases you from the lease. Be clear with your subtenant about expectations, and provide copies of your lease agreement and house rules.

Steps to Take If Your Landlord Denies Subletting

If your landlord refuses your sublet request and your lease requires approval, you must comply—even if you are facing hardship. Attempt to negotiate, or consider ending your lease early per its terms.

If you proceed with an unauthorized sublet, you risk eviction. Always follow the formal permission process and keep written records.
