Find your mechanics lien filing deadline and lien enforcement (foreclosure) deadline based on your state and last day of work. Missing a lien deadline can wipe out your right to get paid — this timeline tracker shows the dates and days remaining at a glance.
Mechanics lien filing & enforcement
A mechanics lien (also called a construction or materialman's lien) is the most powerful tool a contractor, subcontractor, or supplier has to get paid — it attaches a claim to the property itself. But it only works if you record it within your state's strict deadline, measured from your last day of work or last delivery of materials (or from project completion, depending on the state). Miss that window by even a day and your lien rights generally vanish, leaving you to chase payment through ordinary collections.
Deadlines range widely — from about 60–90 days in states like California, Florida, and Georgia to 6–8 months in states like Pennsylvania and New York. Many states also require a preliminary or pre-lien notice early in the project to preserve your rights, and a separate, later deadline to enforce (foreclose) the lien — often one year after recording. This calculator gives you the typical filing window, the enforcement deadline, and a clear countdown so nothing slips.
Counted from last furnishing or completion. The hard cutoff to record your lien — no extensions.
Many states require an early notice to the owner to keep your lien rights alive. Send it on time.
After recording, you have a limited time (often ~1 year) to sue to foreclose, or the lien expires.
GCs, subs, and suppliers can have different deadlines and notice rules in the same state.
Getting paid is the hardest part of construction, and the mechanics lien is the strongest tool American contractors, subcontractors, and material suppliers have to secure payment. Searches like "how long do I have to file a lien," "mechanics lien deadline by state," and "construction lien filing deadline" spike whenever an invoice goes unpaid. This calculator gives you the filing window and enforcement deadline for all 50 states based on your last day of work.
Many states — including California, Texas, Florida, and Arizona — require a preliminary or pre-lien notice early in the project to preserve your lien rights, and the filing deadline itself ranges from about 60 days to 8 months depending on the state. Miss either and you can lose the right to lien entirely. Enter your state and last work date to see every deadline on one timeline.
A subcontractor in California finishes work on June 1. With a 90-day filing window, the mechanics lien must be recorded by about August 30, and the lien must be enforced (foreclosed) within roughly three months after that. The timeline flags the dates and the days remaining so the deadline is never missed.
