Adding someone to your lease in Illinois is easy if you follow the steps and rules. Whether you want to add a roommate or a romantic partner, let’s go through a guide to help you.

Key Takeaways:

  • Review Your Lease and Talk to Your Landlord – Before adding a new tenant, check your lease for any restrictions and get your landlord’s written approval.
  • Submit Required Info and Paperwork – Be ready to provide applications, background checks, and proof of income for the new tenant if required.
  • Complete and Sign a Lease Addendum – Finalize the change by signing an addendum with all tenants and your landlord, and keep a copy for your records.
    • Review Your Lease

    Before you make any changes, review your current lease. Many leases have clauses about subleasing or adding tenants. Look for terms that mention permission requirements. Some landlords require written consent to add tenants. You’ll also want to look for restrictions. There may be limits on the number of occupants or specific criteria for new tenants.

    • Talk to Your Landlord

    Once you’ve reviewed your lease, talk to your landlord or property management. You can ask for permission. You can formally ask if you can add a new tenant. Provide details about the person, including their background and financial stability. You’ll also want to know about the fees or requirements. Start by asking if there are any fees for the change or requirements for background checks.

    • Gather Info

    If your landlord approves the addition, you may need to provide some paperwork. This can be an application. Some landlords require a formal application from the new tenant. A background check may also be required, so be prepared for your landlord to run a credit or background check on the new tenant. They’ll also ask the new tenant to provide proof of income. Documentation showing that the new tenant can pay rent is often requested.

    • Complete an Addendum to the Lease

    Once you get the okay, you may need to fill out an addendum to your lease. This should include the names of all tenants. You need to list all current and new tenants in your addendum or amendment. You’ll also need to reiterate any lease terms that apply to all tenants and have all parties sign the addendum to make it legal.

    • Give the Addendum to the Landlord

    Once you’ve completed the addendum, give it to your landlord to sign. This step makes the new tenant official and protects everyone’s rights.

    • Notify Utility Companies, if needed

    If the new tenant will be responsible for utilities, you’ll need to notify the companies to update the account information.   * Keep All Papers

    Once it’s all done, be sure to keep a copy of the amended lease and any correspondence. This will be your record in case of future issues.

    In Summary

    Adding someone to your lease in Illinois requires communication with your landlord and following your lease. Follow these steps and you’ll be on smooth sailing and good with your landlord and new roommate. Always consult a lawyer if you have questions or run into problems.
