Under 765 Ill. Comp. Stat. 742 § 9, mobile home park owners in Illinois must clearly spell out all rent and fee terms in the lease and itemize every charge in tenant billings. Rent increases are permitted only at lease renewal, and tenants must receive written notice at least 90 days before the lease expires. The law also prohibits park owners from passing along to tenants the costs of court-ordered fines, penalties, or attorney's fees levied against the owner — unless those costs arose from the tenant's own actions — and restricts when transfer fees and pet fees may be charged.
Plain English — not legal advice.
Operators of mobile home parks subject to 765 Ill. Comp. Stat. 742 § 9 generally ensure that every charge — including lot rent, unit rent, service fees, and any other costs — is individually listed in the lease agreement and in each billing statement sent to residents. Compliant park owners deliver written notice of any rent increase at least 90 days before the current lease term expires, rather than mid-term. Owners also avoid imposing transfer or selling fees unless an actual service is rendered, refrain from billing residents for court-assessed penalties or attorney's fees incurred by the park, and only charge pet fees to home-owning residents when a park service related to the pet is offered and accepted.

Residents of Illinois mobile home parks have rights under 765 Ill. Comp. Stat. 742 § 9 to receive a lease and billing statements that clearly itemize every charge, and to receive at least 90 days' advance written notice before any rent increase takes effect at renewal. If a park owner attempts to pass along costs from a court judgment, fine, or attorney's fee assessed against the owner — or charges a pet fee without offering a related service — those charges may conflict with this provision. Tenants who believe a fee or rent increase violates § 9 may consider documenting the charges, contacting a local tenant-rights organization, or exploring whether a complaint or legal defense is available under Illinois law.
