If you build in Massachusetts, the rules that govern your business sit in three places: the state licensing authority, the state lien statute, and the state prevailing-wage law. Cost bands, permit timelines, and common project types layer on top. Get any of these wrong and you bid the wrong number, miss the lien deadline, or lose the certificate of occupancy. Here’s what Massachusettscontractors need to know in 2026, plus how BuildCrux fits into your daily workflow.
BuildCrux runs AI estimating, scheduling, change-order management, lien-aware invoicing, mileage tracking, and customer communication in one place. Every screen is built for the field, not the back office. The numbers below come from current state law, published cost references, and 2026 market data. Verify specific project rules with your AHJ before bidding.

Mechanics liens in Massachusetts
Filing deadline: 90 days after recording of Notice of Substantial Completion or Notice of Termination (whichever earlier); 120 days after last work if no notice recorded. Lien is filed with the registry of deeds.
Preliminary notice: Massachusetts requires a Notice of Contract recorded with the registry of deeds at the start of work to anchor lien rights. Sub-tier claimants must also file a Notice of Identification within strict deadlines.
Lien rights are how you actually get paid when an owner stops paying. Missing the deadline forfeits the security entirely. The mechanics lien is the contractor’s primary security; the preliminary notice is the prerequisite that protects it. Read the lien waiver entry too — that’s the document you’ll exchange for every progress payment.
BuildCrux tracks your last-work date per project and surfaces lien-deadline reminders so the math doesn’t happen on the back of an envelope at month-end.
Prevailing wage in Massachusetts
Massachusetts has one of the strongest state prevailing-wage laws in the US, covering all public works regardless of project value. The Division of Occupational Safety publishes wage rates. Project Labor Agreements (PLAs) are common on large public projects.
For background on how prevailing-wage rules work, see our prevailing wage glossary entry and the Davis-Bacon Act explainer. The federal U.S. Department of Labor wage determinations site publishes prevailing rates on federally funded projects.
