At-a-glance
- Licensing body: Massachusetts Board of Building Regulations and Standards (BBRS)
- License threshold: Home Improvement Contractor (HIC) registration required; Construction Supervisor License (CSL) required for structural work
- Permit authority: Municipal building department (town or city)
- Typical fees: $150–$500 for a bathroom remodel permit
HIC + CSL
Verify HIC registration at mass.gov/hic. For projects that touch load-bearing walls, verify the CSL. Bathroom remodels typically don't need CSL unless the layout changes structurally, but any tub-to-shower conversion in an older Boston-area home may trigger it if joists need reinforcement.
Older housing stock
Massachusetts has some of the country's oldest housing stock. Boston, Cambridge, Somerville, and North Shore towns commonly reveal cast-iron drains, lead solder in old copper, and plaster-over-lath walls during demo. Budget contingency for surprises.
