In Massachusetts, most renovations that touch structure, plumbing, gas or electrical work need a permit from your city or town.
In Massachusetts, most renovations that touch structure, plumbing, gas or electrical work need a permit from your city or town. Cosmetic finish work such as painting, tiling, cabinets and countertops is exempt from the building permit. On a hired job, who pulls the building permit also matters, because it affects your Guaranty Fund protection.
The finish work exemption comes from the Massachusetts Residential Code (780 CMR Chapter 51). Plumbing, gas and electrical work are permitted separately, through their own inspectors. Under 201 CMR 14.21, a homeowner who hires a contractor and pulls the building permit themselves is generally excluded from the Massachusetts Home Improvement Contractor (HIC) Guaranty Fund for that work.
This guide cites the Code of Massachusetts Regulations (CMR) and the Massachusetts General Laws (M.G.L.) directly. It covers what needs a permit, what does not, the three kinds of permits a typical project involves, how the process runs, and the approvals that sit outside the building department.
Which renovations need a permit?
Under Section R105.1 of the Massachusetts Residential Code (780 CMR Chapter 51), it is unlawful to construct, alter, repair, remove or demolish a building, change its use, or install or alter regulated equipment without first applying to the building official and obtaining the required permit. Section R105.2 lists the work that is exempt, covered in the next section.
The Massachusetts Residential Code is part of the current (10th) edition of the Massachusetts State Building Code, 780 CMR. Under R105.2.2, ordinary repairs need no application or notice to the building official, but a permit is required for work that includes:
- substantially cutting away a wall, partition or part of one;
- removing or cutting a structural beam or load bearing support;
- removing or changing a required means of egress, or rearranging parts of the house in a way that affects egress;
- work affecting mechanical systems, or other work affecting public health or general safety.
In practice, opening a wall, moving a doorway, finishing a basement, reworking a kitchen layout or building an addition all fall on the permit side. Roof covering, replacement windows and siding are not on the exempt list in R105.2 either, and the Construction Supervisor License (CSL) under 780 CMR 110.R5 has specific categories for roof covering and for window and siding work, so plan on a building permit for those too.
Under R105.2.1, emergency repairs may proceed first, but the permit application must be submitted to the building official within the next working business day.
What work is exempt from a building permit?
Under Section R105.2 of the Massachusetts Residential Code, twelve categories of work on one- and two-family homes are exempt from a building permit, including sheds of 200 square feet or less, fences not over 7 feet high, and finish work such as painting, tiling, cabinets and countertops. Exempt from the building permit does not mean exempt from plumbing, gas, electrical or local zoning rules.
The thresholds in R105.2 are specific:
The finish work exemption covers the building permit only. Swapping a countertop is exempt from the building permit; moving the sink under it, or adding a circuit for new lighting, still needs the plumbing or electrical permit. A shed or fence that needs no building permit can still be subject to your town’s zoning and setback rules.
Which home remodeling permits does a project need?
A typical Massachusetts remodel can need up to three separate permits, each with its own inspector: a building permit from the local building official under 780 CMR, a plumbing or gas permit issued to a licensed plumber or gas fitter under 248 CMR 3.05, and an electrical permit filed with the local inspector of wires under M.G.L. c. 143, s. 3L.
The building permit
The local building official issues the building permit under 780 CMR. It covers structure, framing, egress, insulation and the overall scope of the job.
Plumbing and gas permits
Under 248 CMR 3.05, plumbing or gas fitting work cannot be installed, altered, removed, replaced or repaired until the inspector has issued a permit. Plumbing permits are issued only to properly licensed individuals, not to apprentices, and gas permits are likewise issued only to properly licensed individuals. In practice, your licensed plumber or gas fitter pulls these permits. Under the same rule, repairing a leaking faucet or clearing a stoppage does not need a permit.
Electrical permits
Under M.G.L. c. 143, s. 3L, anyone installing electrical wiring or fixtures for hire must give notice to the local inspector of wires, through a permit application, and must notify the inspector in writing when the work is complete. On a remodel, the licensed electrician doing the work normally handles this.
How does the permit process work?
Under the Massachusetts Residential Code, the building official must issue or deny a permit in writing within 30 days of filing (R105.3), the permit becomes invalid if work does not start within 180 days of issuance (R105.5), and permitted work must stay exposed until the inspector approves it (R110.1). Each city or town runs its own building department, but this framework is the same statewide.
- Application. The application describes the work, the location and the intended use, includes construction documents and the valuation of the work, and is signed by the owner or an authorized agent. Under R105.3 it must include the registration number of any home improvement contractor on the job, which gives you a simple way to confirm who is responsible for the work.
- Review and zoning check. Under R105.3, before a permit issues, the work has to comply with zoning, water supply, workers’ compensation insurance and flood hazard requirements.
- A written decision within 30 days. Under R105.3, the building official must issue or deny the permit, in writing, within 30 days of filing. That is the legal maximum. Actual review times vary from town to town and depend on how complete the application is.
- Fees. Under R109.1, a permit is not valid until the fees are paid. Each municipality sets its own fees, so the cost varies by town.
- Start within 180 days. Under R105.5, a permit becomes invalid if work does not start within 180 days of issuance, or if work stops for 180 days after it starts. The building official can grant written extensions when asked before the permit expires.
- Keep the permit on site. R105.7 requires the permit or a copy to stay at the job site until the project is finished.
- Inspections, with the work left exposed. Under R110.1, permitted work must stay accessible and exposed until the inspector approves it. In practice, walls are not closed up before the inspections that apply. Which inspections your project needs depends on the scope.
- Final inspection. The job closes with a final inspection sign off.
- Certificate of Occupancy, only in some cases. Under R111.1, a Certificate of Occupancy and Use is required for new buildings, a change of use, or work that increases occupancy. It is not required for exempt work or for alterations that do not change the occupancy, which covers most ordinary remodels.
Who should pull the permit, you or your contractor?
On a hired home improvement job in Massachusetts, obtaining the necessary permits is the contractor’s obligation under M.G.L. c. 142A, s. 2. Under 201 CMR 14.21, a homeowner who secures their own building permit for contracted work is excluded from Guaranty Fund payments for that work, unless the contractor failed to give the notice that c. 142A, s. 2 requires.
Home Improvement Contractor registration
Under M.G.L. c. 142A, s. 9, a contractor may not offer or perform residential contracting on an existing owner occupied home of one to four units unless registered with the Office of Consumer Affairs and Business Regulation (OCABR) under the Massachusetts Home Improvement Contractor (HIC) program. Some narrow categories are exempt, but for most remodeling, registration applies. You can check whether a contractor is a registered Home Improvement Contractor on the state’s public lookup.
What your contract has to tell you
M.G.L. c. 142A, s. 2 requires every contract between a contractor and a homeowner to tell the homeowner three things: which permits are necessary, that it is the contractor’s obligation to obtain them, and that homeowners who secure their own permits will be excluded from the Guaranty Fund. If your contract leaves any of this out, ask for it in writing before you sign.
The Guaranty Fund exclusion
The Home Improvement Contractor Guaranty Fund (the Guaranty Fund) is a state fund set up under M.G.L. c. 142A that can pay eligible homeowners for certain losses on jobs done by registered contractors. Under 201 CMR 14.21, payments from the fund may not go to an owner who secured their own building permit for the contracted work in dispute. The exception: if the contractor failed to give the notice that c. 142A, s. 2 requires, the exclusion does not apply. Under the same rule, awards are capped at $25,000 or the claimant’s actual loss, whichever is less.
If a contractor suggests you pull the permit yourself, you would generally be giving up Guaranty Fund access for that job, since a contract that follows c. 142A, s. 2 will already have told you about the exclusion.
Construction supervisor licensing and the homeowner exemption
Under 780 CMR 110.R5, anyone supervising regulated construction work must hold a Construction Supervisor License (CSL). Homeowners doing work on the one- or two-family home they live in, or intend to live in, are exempt from that license. The same section adds a condition: if a homeowner hires people to do the work, the homeowner acts as the supervisor. A licensed construction supervisor who contracts with a homeowner is still responsible for code compliance, whether or not they pulled the permit.
So a homeowner who pulls the permit on a hired job takes on two things at once: the supervisor role, and, in most cases, the loss of Guaranty Fund access for that contracted work. When the contractor pulls the permit, the contractor’s HIC registration number goes on the application (R105.3).
What other approvals might you need?
Beyond the building permit, a Massachusetts renovation may also need zoning compliance, a certificate from the local historic district commission, an order of conditions from the conservation commission, or lead-safe work practices in a home built before 1978. These approvals can come before or alongside the permit.
- Zoning. R105.3 requires zoning compliance before a building permit issues. Additions, decks and anything that changes the footprint are the usual triggers.
- Local historic districts. Under M.G.L. c. 40C, s. 6, exterior work that affects architectural features in a local historic district needs a certificate from the historic district commission first, and the building permit cannot issue until it does.
- Wetlands. Under M.G.L. c. 131, s. 40, altering a bank, riverfront area or wetland requires filing a notice of intent with the conservation commission and receiving an order of conditions. In plain terms, the town’s conservation commission has to review the plan and set the conditions for the work before it starts.
- Lead-safe renovation in older homes. Under the EPA Renovation, Repair and Painting Program, anyone paid to disturb painted surfaces in a home built before 1978 must be certified and follow lead-safe work practices. Massachusetts is authorized by the EPA to run its own program, so ask about it before work starts if your house predates 1978.

Frequently asked questions
How long does it take to get a building permit in Massachusetts?
Under R105.3 of the Massachusetts Residential Code (780 CMR Chapter 51), the building official must issue or deny a permit in writing within 30 days of filing. That is the legal maximum. Actual turnaround varies by town, by the size of the project, and by whether the application is complete when it goes in.
Can a homeowner pull their own building permit in Massachusetts?
Yes. Under 780 CMR 110.R5, a homeowner working on the one- or two-family home they live in is exempt from the Construction Supervisor License (CSL), but if you hire someone and pull the building permit yourself, you act as the supervisor of that work. Under 201 CMR 14.21 you are also generally excluded from the Home Improvement Contractor Guaranty Fund for the contracted work, unless the contractor failed to tell you about that exclusion as M.G.L. c. 142A, s. 2 requires. Plumbing and gas permits are a separate matter: they are issued to licensed plumbers and gas fitters.
Do replacement windows, roofing or siding need a permit?
Plan on a building permit for all three. Replacement windows, roof covering and siding are not on the exempt list in R105.2, and the Construction Supervisor License under 780 CMR 110.R5 has specific categories for roof covering and for windows and siding. Confirm the details with your local building department before work starts.
Do I need a Certificate of Occupancy after a renovation?
Usually not. Under R111.1, a Certificate of Occupancy and Use is required for new buildings, a change of use, or work that increases occupancy. Alterations that do not change the occupancy end with a final inspection sign off instead.
What happens if work starts without a required permit?
Building or altering a home in violation of 780 CMR is unlawful under R114.1, and under R115.1 the building official is authorized to issue a stop work order.
