Do I Need a Permit to Remodel in Massachusetts?

Massachusetts building code (780 CMR) specifically exempts painting, wallpapering, tiling, carpeting, cabinets and countertops from needing a permit. A permit is required for work that cuts into structural walls or beams, changes a required exit, or involves plumbing, electrical or mechanical systems. Most kitchen and bathroom remodels end up needing a permit because they touch plumbing or electrical, even when the visible work looks cosmetic.
"Do I need a permit for this?" is one of the first questions homeowners ask before a remodel, and the honest answer depends on the specific work, not the room. Do I need a permit to remodel in Massachusetts comes down to a specific list in the state building code. Under 780 CMR Section 105.2, the Massachusetts building code lists 15 categories of work exempt from a permit, and everything else falls under the general permit requirement.
We pull permits on real jobs across Central Massachusetts every month, so here is what the code actually says, translated into plain terms.
What Is Exempt From a Permit
Section 105.2 of the Massachusetts building code lists specific categories of work that do not require a permit. The one most relevant to a typical remodel: "painting, papering, tiling, carpeting, cabinets, counter tops" are explicitly exempt, as long as the work does not touch structural, electrical or plumbing systems. Other exempt categories cover things like small detached storage structures, fences under 7 feet, and small retaining walls, which rarely come up in an interior remodel.
This is why a straightforward cosmetic refresh, new paint, new tile on an existing subfloor, refaced cabinets, new countertops, often does not need a permit on its own.
What Actually Requires a Permit
The code draws a clear line once work goes past cosmetic. A permit is required for the substantial cutting away of any wall or partition, removal or cutting of any structural beam or load-bearing support, removal or change of any required means of egress, or any work affecting mechanical systems, plumbing, electrical, or general public health and safety.
In practice, that covers most of what makes a remodel a remodel rather than a refresh: moving a wall, relocating a sink or shower, adding a circuit, or changing a room's layout in any way that affects how people exit the space.
| Work | Permit Needed? |
|---|---|
| Painting, wallpapering | No |
| New tile, carpet or flooring on existing subfloor | No |
| New cabinets or countertops, same footprint | No |
| Moving or adding plumbing (sink, tub, shower) | Yes |
| Moving or adding electrical circuits | Yes |
| Removing or cutting a structural wall or beam | Yes |
| Changing a room's layout or footprint | Yes |
Kitchen and Bathroom Remodels Specifically
Most full kitchen and bathroom remodels end up requiring a permit, even when the homeowner thinks of the project as cosmetic, because moving a sink, adding a dishwasher line, relocating a shower, or adding an outlet all fall under the plumbing and electrical trigger. A tub-to-shower conversion that reuses the exact same drain and supply lines can sometimes avoid a permit, but the moment the shower pan moves or a new fixture location is added, the project needs one.

Separate from the building permit question, Massachusetts General Laws Chapter 142A requires any contractor doing more than $1,000 of work on an owner-occupied one-to-four family home to be registered as a Home Improvement Contractor (HIC). The law requires the contract to be in writing, name both parties and their registration numbers, and set a clear price and payment schedule. It also funds a Guaranty Fund that can compensate homeowners up to $25,000 if a registered contractor fails to complete a job or pay a judgment.
You can verify any contractor's HIC registration directly on Mass.gov before signing a contract. Ours is HIC Reg. #654604, alongside our MA Construction Supervisor License #CS-085498.
Why Skipping a Permit Is a Bad Trade
Unpermitted work that should have had a permit creates real problems later: it can complicate a home sale when a buyer's inspector or the title company asks for permit records, and insurance claims tied to unpermitted work can be denied. None of that savings is worth the risk on a project that increases your home's value and is meant to last for decades.
The Bottom Line
Cosmetic work like paint, tile and cabinets is exempt from a Massachusetts building permit, but plumbing, electrical, structural and layout changes are not, which is why most real kitchen and bathroom remodels need one. Confirm your contractor's HIC registration before signing anything. A licensed contractor should tell you upfront whether your project needs a permit, and pull it for you.
