Illinois lien deadlines for contractors

Updated · Checked against primary sources

The short answer

In Illinois, a contractor must record the lien claim within 4 months after completion to hold it against third parties, and within 2 years as against the owner. Subcontractors must serve the owner written notice within 90 days after completing their work, plus a 60-day notice on owner-occupied single-family homes. Suit must be filed within 2 years after completion.

The deadlines

StepRule
Preliminary notice: whoContractors in direct contract with the owner give no preliminary notice. Subcontractors and suppliers must serve the owner (and known lender) a notice of claim. On an existing owner-occupied single-family residence, subcontractors must also notify the occupant early in the job.
Preliminary notice: whenSub 90-day notice: within 90 days after completion of the sub's work, or of extra work or final delivery of extra material (60/24). Residential sub notice: within 60 days after first furnishing (60/21(c)); later notice preserves the lien only to the extent the owner was not prejudiced by payments made before receiving it. (The 90-day notice is not needed where the contractor's sworn statement already gives the owner notice of the amount due and to whom. Serve by certified or registered mail, national tracked courier, or personal service; served when mailed or placed with the carrier.)
File or register the lienContractor: record a verified claim for lien with the county recorder within 4 months after completion (or completion of extra work) to enforce against other creditors, encumbrancers and purchasers; as to the owner, within 2 years after completion (60/7). Subcontractors: same time limits as the contractor (60/28), running from completion of their own work.
Enforce or perfect itSuit to enforce must be commenced (or counterclaim filed) within 2 years after completion of the contract or of extra work or material (60/9). If the owner or an interested party serves a written demand, suit must be filed within 30 days or the lien is forfeited (60/34).
Residential jobsOwner-occupied single-family residence: the contractor must give the owner the boldface sworn-statement notice before the first payment (60/5(b)), and must give the owner written notice within 10 days after recording a lien, or the lien is extinguished to the extent of the owner's resulting damages (60/7(d)). Subs must give the 60-day notice under 60/21(c).

General information from the statutes cited below, checked 2026-09-24; one or more details come from a secondary source and are noted. Lien law is strict and details depend on your role and contract. Confirm with a construction lawyer in Illinois before relying on a deadline. Read from ILGA official text. Sections 5, 21 and 24 were amended by P.A. 103-827, effective 1-1-2025 (adds tracked courier service for the 90-day notice). The 60-day residential notice is in 60/21(c), not 60/5.

Where Pavado comes in

How Pavado builds a CRM around your jobs

Lien rights are usually lost to a calendar, not a court. We build CRMs that start each job's notice and lien clocks from its real start and completion dates and remind you before every deadline, so the rights you earned by doing the work are still there when a customer stops paying.

Instead of bending your shop around someone else's software, we build the system around how your jobs actually move, and connect it to what you already use.

  • Your pipeline, your stages. From first call to paid invoice, set up the way your team already works.
  • Automations for the busywork. Follow-ups, reminders and handoffs that happen without anyone remembering.
  • One record per customer. Calls, quotes, jobs, photos and invoices in one place instead of five apps.
  • Connected to your stack. QuickBooks or Xero, Gmail or Outlook, payments and e-sign, plus thousands more through Zapier and an API.
