Written contract rules in Massachusetts

Contractors operating in Massachusetts are required by statute to provide a written contract for jobs valued over $1,000. The contract must include scope, total price, payment schedule, start and completion dates, and (where applicable) the contractor's license number.

Right-to-cancel notice

For home-improvement and door-to-door sales, Massachusetts requires the contract to include a written notice of the consumer\u2019s right to cancel within 72 hours. The notice must be conspicuously displayed and accompanied by a separate cancellation form.

Late fees on past-due invoices

The maximum late fee a contractor may charge in Massachusetts is 1.5% per month under Mass. Gen. Laws ch. 271, §49. The fee must be disclosed in the contract or on the invoice itself before it can be enforced. Civil usury cap 20%/yr; criminal usury 20%+ requires registration.
