Evanston, Ill., City Code § 5 § 5-3-7-1

(A) If there is a material noncompliance by the housing provider with the rental agreement or with Section 5-3-5-1 or 5-3-5-3 , the tenant may deliver a written notice to the housing provider specifying the breach and that the rental agreement will terminate, and the notice will expire, on a date not less than ten (10) days after receipt of the notice, unless the breach is remedied by the housing provider prior to the expiration of the notice. If the breach is not remedied prior to the expiration of the notice, the rental agreement shall terminate as provided in the notice. The tenant may not terminate for a condition caused by the willful or negligent act or omission of the tenant, a member of the tenant's family, or other person on the premises with the tenant's consent. If the tenant does not vacate the property within thirty (30) days after the expiration of the ten-day period, then the tenant's written notice shall be deemed withdrawn and the rental agreement shall remain in full force and effect.
(B) Except as provided in this Chapter, the tenant may recover damages and obtain injunctive relief for any material noncompliance by the housing provider with the rental agreement or with Section 5-3-5-3 . If the housing provider's noncompliance is willful, the tenant may recover reasonable attorney fees. The housing provider shall have as an affirmative defense to this action that the condition was caused by a willful or negligent act or omission of the tenant, a member of the tenant's family, or other person on the premises with the tenant's consent.
(C) If the rental agreement is terminated, the housing provider shall return any security deposit recoverable by the tenant under Section 5-3-5-1 and all prepaid rent.
