Illinois Squatters Rights: Adverse Possession and How Removal Actually Works

Illinois requires 20 years of continuous, hostile, actual, open, notorious, and exclusive possession under 735 ILCS 5/13-101. Two 7-year shortcuts exist: possession under color of title made in good faith combined with payment of all taxes for 7 successive years (735 ILCS 5/13-109), and a parallel rule for vacant unoccupied land under 735 ILCS 5/13-110. Without a paper title and seven years of tax payments, a squatter faces the full 20-year period, and Illinois courts construe every element strictly against the claimant.

For years Illinois was notorious for treating settled squatters as de facto tenants: police would classify the occupation as a civil matter and owners had to file a full eviction case under the Eviction Act, 735 ILCS 5/9-101 et seq. Public Act 104-0029 (SB 1563), signed July 21, 2025 and effective January 1, 2026, closes that loophole by clarifying that the Eviction Act does not limit law enforcement's authority to enforce the criminal trespass laws against unauthorized occupants who have no colorable claim of tenancy, and by criminalizing the use of fraudulent leases or false claims of residency. Illinois did not create a Florida-style affidavit-to-sheriff procedure -- removal still runs through the responding officers' trespass determination, so documentation (deed, utility records, police report, photos of forced entry) is what converts a 'civil matter' shrug into an arrest. Where any genuine tenancy question exists, the owner still needs an eviction order and sheriff-executed removal.

Anyone who ever had lawful possession -- a holdover or non-paying tenant, an occupant under an oral agreement, a roommate the leaseholder invited, or a purchaser in a failed deal -- must be removed through an Eviction Act case with notice, judgment, and sheriff enforcement. SB 1563 expressly protects due process for lawful tenants and cannot be used to bypass eviction, so its police-removal clarification reaches only occupants whose presence is criminal trespass from the start.

Only the county sheriff acting on a court order may forcibly remove an occupant with any colorable right; changing locks, removing doors, or shutting off heat, water, gas, or electricity is an unlawful self-help eviction. The Rental Property Utility Service Act, 765 ILCS 735, adds full rent abatement for each month a utility was off, consequential damages, and statutory damages up to $300 per tenant for deliberate or reckless shutoffs, and Chicago's RLTO lets a locked-out tenant recover two months' rent or twice actual damages, whichever is greater, plus attorney's fees.

Public Act 104-0029 (SB 1563), signed July 21, 2025 and effective January 1, 2026, is Illinois's entry in the national anti-squatter wave: it amends the Eviction Act to make clear that police may remove criminal trespassers without the owner filing an eviction case, distinguishes unlawful squatters from tenants entitled to due process, and criminalizes fraudulent leases and false identity claims used to feign residency. A broader 'Stop Squatters Act' (SB 1985) did not advance. The adverse possession statutes were unchanged.

The classic Illinois mistake was assuming nothing could be done without a months-long eviction -- since January 1, 2026 that is no longer true for genuine trespassers, but owners must arrive with proof of ownership and of unlawful entry, because officers still will not adjudicate dueling stories. The opposite mistake is over-reading SB 1563: it is not a removal order against holdover tenants, ex-partners, or anyone with a colorable agreement, and self-help against those occupants remains as costly as ever, especially under Chicago's RLTO.
