Mechanics Lien Deadline Calculator
Every state runs its own clock on notice, lien, and bond claim rights, and most of those clocks start from your own dates on the job. Select your state, enter your project facts, and get your deadlines calculated under that state's statute, with a free follow-up from our attorney network. All 50 states and D.C.
How the calculator works
Tell us about the project
Select your state, your role (GC, subcontractor, or supplier), the project type, and your first and last dates on the job. That is everything the calculator needs.
Deadlines counted to the statute
Your notice, lien filing, bond claim, and enforcement deadlines are calculated under the selected state's statute, from the correct trigger dates for your role.
An attorney-network review
A member of our team reviews your project details and contacts you within one business day to confirm the deadlines and walk through your options.
Lien rights are won or lost on the calendar
A mechanics lien is one of the strongest collection tools in construction, but it only exists if every notice and filing lands inside its statutory window. Miss a preliminary notice and the lien may never attach. Record the lien late and it is unenforceable no matter how clearly you are owed the money. The windows differ by state, by your role on the project, and by whether the project is private or public, so the only safe starting point is counting your own deadlines from your own dates.
If a date has already passed, you may still have options. See what to do after a missed lien deadline, review preliminary notice requirements by state, or start with how a mechanics lien works.
Deadline rules by state
Every state page covers who can lien, the notice requirements, the filing and enforcement deadlines, and the bond claim rules for public work in that state.
Deadline calculator FAQs
How does the mechanics lien deadline calculator work?
Pick your state, choose your role on the project and the type of project, and enter your first and last dates furnishing labor or materials. The calculator applies that state's lien and notice rules to your dates, and a member of our team reviews the results with you within one business day.
Which deadlines does it cover?
The deadlines that decide whether you keep your payment rights: preliminary notice and notice to owner windows, the mechanics lien recording deadline, payment bond claim deadlines on public projects, and the deadline to file suit to enforce.
Why do the dates I enter matter so much?
Most lien and notice deadlines are measured from your own dates on the job, usually your first or last date furnishing labor or materials. The same project can produce different deadlines for a general contractor, a subcontractor, and a supplier, which is why the calculator asks for your role before it counts anything.
Is the calculator free, and is it legal advice?
It is free. The results are estimates for informational purposes only and are not legal advice. Deadlines can shift with project-specific facts, contract terms, and how courts read the statute, which is why an attorney in our network verifies your deadlines before you rely on them.
This calculator provides estimated deadlines for informational purposes only. It does not constitute legal advice and does not create an attorney-client relationship.
