Every year, contractors and suppliers forfeit enormous sums not because their claims were weak, but because a date passed. Lien rights are the strongest payment security in construction — and the most perishable. This guide walks the full deadline chain, in the order the clocks actually start.
In many states, your lien rights begin dying the day you start work. California expects its 20-day preliminary notice within 20 days of first furnishing; Florida's Notice to Owner runs on a 45-day clock; Washington allows 60 days; Texas runs monthly notices due by the 15th of the third month after each month worked. Miss the window and — depending on the state — you lose lien rights for early work or for the entire claim.
The professional habit is boring and absolute: send the preliminary notice on every job, at mobilization, as routine paperwork. It is not aggressive; in notice states it's simply how the industry works, and notice-senders statistically get paid faster. See your state's exact window in the free deadline calculator.
The headline deadline. Most states give you a window measured from completion of the work — yours or the project's, and that distinction matters — commonly 60 to 180 days. Two traps dominate:
A recorded lien is not forever — you must file a foreclosure suit within the enforcement window or the lien silently dies. California allows just 90 days; some states allow a year or more. Owners' attorneys know sloppy claimants miss this one, and simply wait them out. Calendar the enforcement date the same day you record.
You can't lien a courthouse. Public work substitutes payment-bond claims — the federal Miller Act (notice within 90 days of last furnishing for second-tier claimants; suit within one year) and state Little Miller Acts with their own chains. Bonded private jobs work similarly. Different instrument, identical discipline.
Deadlines don't fail because contractors are careless; they fail because every project runs four clocks in parallel across different states with different triggers. The fix is systematic: compute every date from project facts the day the job opens, put them on one calendar, and alert long before the law's edge. That's literally what LienWarden does — computed deadlines, 60/30/7-day alerts, and the notice drafted when the window opens. Founding members get 50% off for a year with code FOUNDING50.
