How To Sublet Legally In Illinois

Posted by Roger Graham | Checked for accuracy and updated

The Bottom Line: The Bottom Line: According to Illinois Law, you have the right to sublet as long as you get permission from your landlord.

The Chicago Residential Landlord Tenant Ordinance makes Chicago law especially tenant friendly and guarantees that you have the absolute the right to sublet your apartment at no additional cost. You need to follow the guidelines, but the landlord cannot “unreasonably refuse” the right to sublease.

  1. Check your lease. Most likely, your lease contains a clause which requires you to obtain your landlord’s approval prior to subletting.

  2. Mail a Letter. You should send a letter to your landlord via certified mail, return-receipt requested, and save a copy of the document for your own records. Certified mail is the only proof of delivery that most courts will accept and thus is the best way to protect yourself. The letter should clearly outline the terms of the agreement and include the following information:

    • The term (starting and end dates) of the sublet or the date of the proposed assignment (30 days from when you sent the letter)
    • The name of the proposed subtenant or assignee
    • The permanent home address of the proposed subtenant or assignee
    • Your reason for subletting or leaving permanently
    • Your new address during the sublease if applicable
    • The written consent of any co‑tenant
    • A copy of the proposed sublease

  3. Wait for approval. Within thirty days of mailing the initial notice your landlord must respond to your inquiry. If the landlord doesn’t respond then their consent is assumed and you are free to sublet.

    If your landlord rejects your request, know that they can only refuse proposed subtenants based on legitimate factors.

    Legal grounds for refusal may include:

    • The financial responsibility of the proposed assignee or subtenant.
    • Intended use of the property.
    • The legality of the proposed use.
    • The nature of the occupancy.
    • The compatibility of the tenant’s use with the uses of the other tenants.

  5. Stay Responsible. Remember just because you aren’t living in the place anymore, doesn’t mean that you aren’t held accountable to the terms of your lease. It is still up to you to make sure that the rent is paid on time and that none of the lease terms are broken.
