Weymouth's Department of Municipal Licenses and Inspections, at Town Hall on Middle Street, permits and inspects construction for the South Shore town of nearly sixty thousand people — one of the largest municipalities in the Commonwealth still governed as a town, though with a mayor and council rather than town meeting. The department publishes an unusually explicit list of what needs a building permit: tents, signs, roofing, demolition, additions, siding, tool sheds, above-ground and in-ground pools, window, door and trim replacement, fences above seven feet, decks, wood stoves, sheet metal, alterations and new construction.
Its inspection booking rule is the tightest in this band. Inspection requests go to the inspector directly, on weekdays between half past seven and nine in the morning, because the inspectors leave promptly at nine for their daily rounds. And the department is direct about wetlands: if there are wetlands near a project, or the applicant is unsure whether there are, it directs them to the conservation office on the third floor of Town Hall before going further.
This guide covers the Town of Weymouth. Braintree, Quincy, Hingham, Holbrook, Abington and Rockland run their own building departments under the same state code.
Ninety minutes to book an inspection. Weymouth asks that inspection requests be made by contacting the inspector directly on weekdays between 7:30 am and 9:00 am, and states plainly that inspectors leave promptly at 9:00 am for their daily inspections. Missing that window means missing the day — on a job with several trades to sequence, the morning call is the whole schedule.
What requires a building permit in Weymouth?
Massachusetts runs one statewide code and enforces it town by town. The Massachusetts State Building Code, 780 CMR, is written by the Board of Building Regulations and Standards and applies in every city and town without local amendment — there is no county layer at all, and Weymouth enforces the same code as every other municipality in the Commonwealth. The 10th edition took effect on October 11, 2024, ran concurrently with the 9th until June 30, 2025, and has been the only code in force since July 1, 2025. It is built on the 2021 International Codes — building, residential, existing building, mechanical, energy, swimming pool and fire — with Massachusetts amendments substantial enough that the model text alone will mislead. The residential provisions sit in Chapter 51, which adopts the 2021 IRC as amended. What is local in Weymouth is the building department, the fee schedule, zoning, and the zoning by-law and the department's published permit list.
The code draws the exemption line, and it is the same line everywhere in the Commonwealth. Ordinary repairs need no permit; anything that constructs, reconstructs, alters, repairs, removes or demolishes a building, or changes its use or occupancy, needs one from the building official. Electrical work runs under the Massachusetts Electrical Code, 527 CMR 12, and plumbing and gas under the Fuel Gas and Plumbing Code, 248 CMR, each permitted and inspected by Weymouth's own wiring and plumbing inspectors rather than the building inspector.
Typically permit required
- Tents, signs, roofing, demolition, additions, siding, tool sheds, pools above and in ground, window, door and trim replacement, decks, wood stoves, sheet metal, alterations and new construction
- Fences above seven feet in height
- Any work near wetlands, which goes to the conservation office before the building department
- New buildings, additions and any structural work on an existing building
- Alterations, repairs and reconstruction under the existing building provisions, and any change of use or occupancy
- Decks, sheds above the code threshold, swimming pools and solar installations
Often exempt
- Ordinary repairs that do not alter structure, egress or systems — but the department's published list reaches further than most, down to trim replacement
- Ordinary repairs that do not alter structure, egress or systems
- Painting, wallpapering, flooring, cabinets and similar finish work
- Like-for-like replacement that the code places below the permit threshold
- Work on a building owned by the Commonwealth, which the State Building Inspector enforces rather than the town
What is actually local, and what is not
The code is the Commonwealth's and cannot be amended locally. Weymouth's layer is the building department itself, its fee schedule and filing route, the zoning bylaw or ordinance and the zoning enforcement that precedes the permit, the conservation commission's wetlands jurisdiction under the Wetlands Protection Act, and the ninety-minute morning inspection window and the conservation office the department routes wetland questions to.
Who handles permitting in Weymouth?
The Department of Municipal Licenses and Inspections is the enforcing office, with the building commissioner or inspector of buildings as building official under the state code and the town's wiring and plumbing inspectors covering their own trades. The conservation office on the third floor of Town Hall administers the Wetlands Protection Act, the zoning board of appeals hears relief under the state Zoning Act, the planning board handles site plan review, and commercial projects are reviewed by several departments at once.

Permit types
Residential permits
A Weymouth house project checks the department's published permit list first — it reaches trim replacement, tool sheds and wood stoves — then files with the supervising individual's Construction Supervisor Licence and, on residential work for an owner-occupant, the contractor's Home Improvement Contractor registration. If wetlands are anywhere near the site, or their presence is uncertain, the conservation office is the first call rather than the building counter.
How Massachusetts contractor credentials work
Massachusetts issues no general contractor licence. It issues two separate and non-interchangeable credentials, and permit-required work usually needs both. The Construction Supervisor Licence, under M.G.L. c. 143 and 780 CMR, is an examined licence from the Office of Public Safety and Inspections held by the individual supervising the work — unrestricted for any building, restricted for one- and two-family dwellings up to 35,000 cubic feet, or one of the specialty classes. Home Improvement Contractor registration, under M.G.L. c. 142A, is a consumer-protection registration with the Office of Consumer Affairs and Business Regulation, required of anyone contracting residential work on an existing owner-occupied building of one to four units, with a written contract required above one thousand dollars and access to the state Guaranty Fund behind it. A homeowner may take out the permit on their own one- or two-family home under the supervisor licence exemption by signing the affidavit and warning notice — but doing so waives the Guaranty Fund protection a registered contractor's permit would carry. Electricians, plumbers and gas fitters hold their own state licences, and Weymouth verifies all of them at the counter.
Commercial permits
Commercial work in Weymouth is reviewed by several departments at the same time rather than in sequence, which shortens the path when the submission is complete; initial plan review runs to about thirty days, and the fire department has its own review period with extensions available on written request. Applications are checked for completeness before being assigned to a reviewer, so an incomplete file waits without being read.
Zoning, conservation and the thirty-day clock
A Massachusetts building permit application is filed with the building official, who reviews the construction documents and issues or refuses it — and under 780 CMR the official must act within thirty days of a complete application, with a written statement of the reasons for any refusal. The approvals that run ahead of it are the local ones: zoning sign-off under Weymouth's bylaw or ordinance, and, where the work is within a hundred feet of a wetland or within the riverfront or floodplain areas, an order of conditions from the conservation commission under the Wetlands Protection Act, which is a hearing rather than a counter transaction. In Weymouth the Back River, the Fore River and the town's ponds bring the conservation office's Wetlands Protection Act jurisdiction and coastal floodplain review into the file, and the former naval air station redevelopment carries its own approval history. Appeals from the building official go to the local zoning board of appeals on zoning matters and to the State Building Code Appeals Board on code matters.
Weymouth permit costs and fees
Fees follow the town's published schedule, alongside the applications, with the trades charged separately under the state codes.
| Item | Fee or rule |
|---|---|
| Building permit | Town schedule, published with the applications, by project type and value |
| Wiring permits | Filed with and inspected by the town's wiring inspector under the state electrical code |
| Plumbing and gas permits | Filed with and inspected by the town's plumbing inspector under the state code |
| Conservation | Wetlands Protection Act filing fees through the conservation office |
| Zoning relief | Zoning board of appeals application under the state Zoning Act |
| Certificate of occupancy | Issued after the final inspections on new buildings and changes of use |
The list reaches trim and tool sheds. Weymouth's published permit list includes window, door and trim replacement, tool sheds, wood stoves, siding, roofing and fences above seven feet — work that in some towns falls below the threshold. Reading the list before quoting a job is cheaper than discovering mid-project that the trim replacement needed a permit.
Trade permits and who may pull them
The trades are permitted separately from the building permit and inspected by the town's own wiring and plumbing inspectors, under the state codes and licences rather than any local one.
Permit required
- Work near wetlands — the conservation office before the building department
- Electrical — state-licensed electrician; separate wiring permit under 527 CMR 12
- Plumbing and gas — state-licensed plumber or gas fitter; separate permits under 248 CMR
- Sheet metal work — state sheet metal licence where the work falls under it
- Fire protection and alarms — fire department review under 527 CMR alongside the building permit
Typically exempt
- Like-for-like fixture and device replacement where the state codes allow it without a permit
- Work the licensing boards place outside their permit requirements
How to apply for a Weymouth building permit
Zoning sign-off under the local bylaw or ordinance, and any special permit or variance from the zoning board, precede the building permit.
Work near wetlands, rivers or floodplain needs an order of conditions under the Wetlands Protection Act before the permit.
The Construction Supervisor Licence of the supervising individual, and the Home Improvement Contractor registration where the work is residential.
The building official reviews the documents against 780 CMR and the energy code the town has adopted.
Fees are the town's own and are due before issuance; trade permits are filed separately.
Footing to final, with the wiring and plumbing inspectors on their own trades, then the certificate of occupancy.
Review, corrections and what actually causes delay
Weymouth checks applications for completeness before assigning them to a plan reviewer, so an incomplete file simply waits; initial plan review runs to about thirty days, and commercial projects are reviewed by several departments concurrently. What delays a file here is an inspection call made after nine in the morning and a wetlands question deferred to the permit stage.
Inspections in Weymouth
Inspections follow the code's sequence — footing and foundation, frame, insulation and final — with the wiring and plumbing inspectors covering their own trades, and are requested from the building department by permit number. Work that passes final receives a certificate of occupancy for new buildings and changes of use, or a certificate of inspection where the code requires one. Buildings in the use groups listed in 780 CMR Section 110 also carry periodic inspections, with proof of maintenance filed with the building official. Weymouth's inspectors take booking calls weekdays between 7:30 am and 9:00 am and then leave for their rounds; the town's wiring and plumbing inspectors carry their own trades, and the certificate of occupancy follows the finals.
