Enter your project dates.
Pick your state, your role, and the project type, then enter the trigger date. The calculator applies the standard statutory period — it does not account for weekends/holidays, notices recorded by others, tolling, or your specific contract. Treat every result as a date to verify, not a date to rely on.
Enter your dates to see deadlines.
The deadlines, with citations.
Every period below is tied to the statute that creates it. These are the load-bearing dates in a private-works mechanics lien; missing one usually forfeits the remedy. Want the full walkthrough for one state? Read the California mechanics lien deadline guide.

Mechanics lien deadlines turn on facts this tool cannot know: your exact tier in the contract chain, whether others have recorded notices, weekends and holidays, contract terms, tolling and exceptions, and statutory amendments. Statutes change. The calculator performs plain calendar arithmetic on the standard period — it does not judge which rule applies to your situation.
Before you rely on any date, notice requirement, or strategy, verify it against the current statute and consult a licensed attorney in the relevant state. We make no warranty as to accuracy or completeness, and accept no liability for reliance on this information.
