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 60,000 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 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 7 feet, decks, wood stoves, sheet metal, alterations and new construction.
Its inspection booking rule is tight. 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.
90 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?

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 90-minute morning inspection window and the conservation office the department routes wetland questions to.
Massachusetts has one State Building Code, 780 CMR, for every city and town; towns cannot rewrite it, though many opt into a stricter energy code. The trades run under their own state codes. Massachusetts rules
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.

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.
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 30 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 30-day clock
The approvals that run ahead of the building permit are the local ones: zoning sign-off under Weymouth's bylaw or ordinance, and, where the work is within 100 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.
Massachusetts has no general contractor licence: the supervising individual holds a Construction Supervisor Licence, and contractors working on existing owner-occupied homes register as Home Improvement Contractors. Massachusetts rules

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 | $10 per $1,000 of construction value on single-family permits (minimum $50); $20 per $1,000 on all others (minimum $100) |
| 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 7 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.

How to apply for a Weymouth building permit
Zoning sign-off under the local bylaw or ordinance, and any variance or special permit the project needs, must come before the building permit.
Work in or near wetlands, rivers or land that floods needs conservation commission approval under the Wetlands Protection Act, usually an order of conditions, before work starts.
The Construction Supervisor Licence of the supervising individual, and the Home Improvement Contractor registration where the work is on an existing owner-occupied home of one to four units.
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 a certificate of occupancy for a new building or change of use, or a certificate of completion for other work.
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 30 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 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.
