What a Illinois lease should cover

  • Names of the landlord and every adult tenant, and the property address
  • The lease term (start and end) and the monthly rent and due date
  • The security deposit amount (within Illinois’s legal cap)
  • Late fees, utilities, pets, and maintenance responsibilities
  • Signatures of the landlord and each tenant

Know your Illinois rules

State law — not the lease — controls things like the maximum security deposit, how fast it must be returned, how much notice is required to enter or to end a month-to-month tenancy, and required disclosures. Check the current Illinois landlord-tenant rules so your lease lines up with them.

Frequently asked questions

Is this lease valid in Illinois?

A written lease that clearly identifies the parties, the property, the term, and the rent is generally enforceable in Illinois when both sides sign. This template covers those essentials. Illinois, like every state, has landlord-tenant rules (on deposits, entry, and notice) that override anything conflicting in a lease — so review your state’s rules and, for complex situations, have an attorney check it.

How much security deposit can a landlord charge in Illinois?

Illinois does not set a statutory cap on the security deposit, so the amount is negotiable — but it must be returned within 45 days after you move out (as of 2026). Source: 765 ILCS 710 (Security Deposit Return Act).

Do I need to notarize a lease in Illinois?

Most residential leases do not need to be notarized to be valid. Signatures from the landlord and each tenant are what matter. Longer leases (often over one year) can have extra formality requirements in some states — check Illinois’s rules if your term is long.
