Do you need a permit to remodel a kitchen or bathroom in Massachusetts?

Which kitchen and bathroom work needs a building permit in Massachusetts?

Work that changes the structure or the walls generally needs a building permit under the Massachusetts State Building Code, 780 CMR. The state's own guidance chart, published by the Home Improvement Contractor program, lists structural carpentry, structural flooring, sheetrock, plastering, insulation, demolition, and window and door installation as work that requires a building permit.

In a real remodel that covers most of the job. Once you open a wall to move a sink, hang new drywall around a shower or swap a window, you are in permit territory. The state is clear that the chart is general guidance only and that the project's specifics decide it, so the building official in your town has the last word.

• Structural carpentry, framing and structural floors: permit
• Sheetrock (drywall) and plaster: permit
• Window or door installation: permit
• Demolition and insulation: permit

What remodeling work usually does not need a permit?

Interior painting needs no building permit, no Construction Supervisor License and no Home Improvement Contractor registration, according to the state chart. Exterior painting needs no permit either, though the contractor doing it must be HIC registered.

Kitchen cabinets and shelving on their own usually need no building permit, but the chart notes a permit may be required if they are part of a larger project. Finish flooring such as tile or carpet is listed as a maybe, mainly where a fire rating comes into play in three- and four-family buildings. Cabinet refacing, new hardware and paint are cosmetic, and in most cases that is all they are.

If all you want is a fresh look, that is worth knowing before you plan a bigger job than you need. Painted cabinets, new counters on sound boxes and a new backsplash can change a kitchen without touching the walls.

Who pulls plumbing and gas permits in Massachusetts?

Only a licensed plumber can get a plumbing permit in Massachusetts. The Board of State Examiners of Plumbers and Gas Fitters states that the local plumbing inspector must issue a permit before any plumbing is installed, altered, removed, replaced or repaired, and that permits for plumbing work are issued only to licensed plumbers.

Small repairs like fixing a leaky faucet or clearing a blocked drain need no permit. Replacing or relocating a faucet, valve or piping does. Gas piping works the same way through a licensed gas fitter, and a licensed master or journeyman plumber may also do gas fitting work.

That is why MR Construction Revolutions does not do plumbing or gas work itself. On a bathroom or kitchen remodel the licensed plumber pulls the plumbing permit and the plumbing inspector signs off on it.

Who handles the electrical permit?

The licensed electrician doing the work files the electrical permit with your town's inspector of wires. Massachusetts law, M.G.L. c. 143, section 3L, requires anyone installing electrical wiring for hire to give notice to the inspector of wires on the state permit application form before the work starts, or within five days of starting it.

When the work is finished, the electrician notifies the inspector, who approves or disapproves it. New lighting, outlets on a kitchen island or a fan in a bathroom all go through that process.

Does the permit need to show the contractor's HIC registration?

Yes. Under the state's Home Improvement Contractor rules, building permits, contracts and advertising for residential contracting must show the contractor's active HIC registration number. Building permits must also state that people who hire unregistered contractors do not have access to the state Guaranty Fund.

There is a second detail worth knowing. The state's homeowner guidance says that if you apply for the building permit yourself, you may not be eligible for the Guaranty Fund. A registered contractor should agree in the contract to pull the building permit, and a contractor who refuses may be unregistered.

Who decides what my project needs?

Your town's building department decides. Every Massachusetts city and town enforces the same state building code, but the local building official reviews the scope, issues the permit and does the inspections.

Ask about permits at the estimate and ask again before anything is ordered. A permit adds time for review and inspections, and that time belongs in the schedule you sign, not in a surprise delay halfway through the job.

• Building permit: issued by your town's building department under 780 CMR
• Plumbing and gas permits: issued by the local plumbing and gas inspector, only to licensed trades
• Electrical permit: filed with the local inspector of wires by the licensed electrician
• Permit card: posted at the job site until the work is complete

In Wakefield and nearby towns

In Wakefield, building permits come from the Inspectional Services & Zoning office at 1 Lafayette Street, which enforces the state building code and town zoning and issues permits for construction, alteration, repair and demolition. The same office has a wiring inspector and a plumbing and gas inspector, so all of the permits on a kitchen or bath remodel run through one building in town. Reading, Stoneham, Melrose and the other towns we serve each run their own building department, so check with the one where the house is. MR Construction Revolutions is based in Wakefield, and we talk through what your project is likely to need at the free estimate.
