Do you need a permit for mold remediation in Boston, MA?

It depends

It depends on scope. Like-for-like cosmetic work in Boston is often exempt, but a permit is required as soon as you change structure, plumbing, electrical or the building envelope.

Massachusetts amends the base code statewide and Boston's Inspectional Services adds its own review, so permitted labor runs well above the national median.

Frequently asked questions

Does Florida license mold remediation?

Yes. Florida requires separate licenses for mold assessors and mold remediators, and with limited exceptions the same company cannot both assess and remediate the same property — which protects you from inflated scope.
