Illinois Mechanics Lien Deadline (2026): 4 Months after Completion for Remodelers
How long a remodeler hired by the homeowner has to record a mechanics lien in Illinois, what notice comes first, and the deadline to sue, worked on three dates.
Not legal advice. General information from each state's lien statute, checked Oct 29, 2026, for a contractor hired directly by the owner of an existing home. Dates are calendar arithmetic; some states move a deadline that lands on a weekend or holiday and some don't, and a recorded notice of completion or commencement can change the clock. Before you rely on a date, check with a construction attorney in your state.
The rule in Illinois

Record within 4 months after completion to bind third parties. Against the homeowner only, you have up to 2 years. Notify the homeowner within 10 days after recording.

Sue within 2 years after completing the contract. If the homeowner demands it, sue within 30 days or lose the lien.
