This is an estimate, not legal advice. Day-counts are the general rule LienWarden tracks for each state; your role, the property type and the notice method can change them.
Save this project in LienWarden. LienWarden keeps every one of these dates for the project in one list and drafts the notice or demand letter when one comes due. Your first project is free and you can start without an account.
How the calculator counts
Each state's lien law sets its deadlines as a number of days counted from an event on the project. LienWarden tracks six of them per state and the calculator applies the same rules the app uses:
- Preliminary notice: counted from your first day of labor or materials on the job.
- Notice of intent to lien, lien recording and payment-bond claims: counted from completion or your last day of furnishing.
- Enforcement (foreclosure) suit: counted from the day the lien was recorded.
- Notice of completion response: counted from the owner's recorded notice of completion, which can shorten your window.
The count is calendar days, so weekends and holidays are included. The calculator flags a deadline that lands on a weekend; some states push those to the next business day and some don't, so plan to file before the weekend.
Across the rules LienWarden tracks, the shortest lien recording window is 45 days from completion (Hawaii) and the longest is 240 days (New York). The difference between states is why a subcontractor who works across state lines can't rely on one rule of thumb.
What it doesn't cover
Lien statutes carry exceptions the calculator can't see: residential and owner-occupied projects, different rules for subcontractors and suppliers than for the contractor hired by the owner, required delivery methods, and filing details such as the property description. Use the dates here to plan, then confirm the rule for your role with the statute (cited on each state page) or a construction attorney.
Questions
How long do you have to file a mechanics lien?
It depends on the state. In the rules LienWarden tracks, the lien recording window runs from 45 days after completion in Hawaii to 240 days in New York. Pick your state in the calculator above to see your date.
What counts as the last furnishing date?
Usually the last day you performed contract work or delivered materials for the project. Warranty work, punch-list corrections or a trip to pick up tools often do not restart the clock, so use the last day of real contract work.
Are the deadlines the same for subcontractors and general contractors?
Not always. Many states set different notice duties, and sometimes different lien windows, depending on whether you contracted with the owner or with someone below the owner. The calculator shows the general rule LienWarden tracks for the state; check the statute for your role.
What happens if I miss the lien deadline?
In most states the right to record a lien for that project is lost, and the unpaid amount becomes an ordinary unsecured debt. You may still be able to sue on the contract or make a bond claim if the project is bonded. See what to do after a missed deadline.
Is this calculator legal advice?
No. This is an estimate, not legal advice. It applies general day-counts and can’t account for every exception, so verify your deadline with the statute or a construction attorney before you rely on it.
