Westwood, Massachusetts Building Permit Guide

In Westwood the Building Division, part of the Community and Economic Development department and led by the Building Commissioner, issues the building permit and the trade permits and reviews plans against the State Building Code and the town’s Zoning Bylaw. All applications go through ViewPoint Cloud, the division says processing can take up to 30 days, and new work follows the Stretch energy code.

What requires a building permit in Westwood?

The Building Division describes its job as permitting new construction, repairs, renovations and demolition, for the building itself and for each trade, and issuing the certificate of occupancy at the end. Its published forms show the kinds of project it sees most often.

Demolition has its own paperwork in Westwood: a Demolition Application Checklist and a Pre-Demolition Asbestos Checklist, with an Asbestos Information Sheet explaining the asbestos step. Projects that move earth have a separate Earth Material Movement Bylaw affidavit. Construction or zoning violations can be reported on a complaint form, sent by email or handed in at 50 Carby Street.

Demolishing an older or historic building

Chapter 250A of the town code, Historic Structure Demolition, adopted by the May 2, 2016 Annual Town Meeting (Article 22), lets the Westwood Historical Commission advise the Building Commissioner on demolition permits. It covers buildings and structures listed on the National or State Register of Historic Places, including contributing properties in the Colburn School and Fisher School Historic Districts, and any building or structure built in whole or in part on or before December 31, 1910. Demolition here means pulling down or razing a structure, or destroying a substantial part of it, either half its volume or half its assessed value; replacing roofing, siding, stairs, railings, windows or similar features does not count, nor does demolishing a non-historic addition or an accessory structure.

The Commissioner sends a covered application to the Commission within seven days. The Commission holds a public hearing within 20 days of receiving it and closes the hearing within 10 days of opening it; if it misses those deadlines, the demolition is treated as approved. Notice is published at least five days before the hearing and sent to the applicant, the owner, the owners of all properties within 300 feet, the Westwood Historical Society and others. If the Commission finds the structure is not significant, or that demolishing it would not be detrimental, it tells the Commissioner within five days and the permit can issue. If it declares the building a preferably preserved historic or architecturally significant structure, taking into account any hardship the owner shows, no demolition permit is issued for up to six months from the date of the original application.

What Westwood decides and what the state holds

The building rules themselves are the state’s. The division lists the codes it enforces, from the 2021 International Residential, Building and Existing Building Codes with Massachusetts amendments to 521 CMR for accessibility, 248 CMR for plumbing and fuel gas, NFPA 70 for electrical work and 527 CMR for fire prevention, and notes that only the 10th edition of the Massachusetts building code has been in effect since July 1, 2025. Westwood’s own decisions are the Zoning Bylaw, the Wetlands Bylaw (Chapter 392), its stormwater rules, the Earth Material Movement Bylaw, the Historic Structure Demolition bylaw (Chapter 250A) and its energy code choice: the Stretch code (Chapter 251 of the town code, Stretch Energy Code), which every application submitted after January 1, 2023 must meet.

Westwood building department: who handles permitting

The Building Division issues all of the construction permits, from the building permit to sprinkler permits, and it also answers complaints and inspects public buildings periodically as the state code requires. Building Commissioner Mike Perkins heads it, with a building inspector, a wiring inspector, an assistant wiring inspector and a plumbing and gas inspector.

Two other offices are often on a project’s path: the Health Division, whose Board of Health staff at 50 Carby Street issue health permits and inspect permitted facilities, and the Conservation and Stormwater Management Division. Weights and measures inspections for Westwood are handled by Norfolk County (781-234-3377), not by the Building Division. The Zoning Division, also at 50 Carby Street, keeps the same hours.

Westwood permit types

Westwood handles permits online from start to finish: the division’s pages say in capitals that all permit applications must be submitted online through ViewPoint Cloud, and the Health Division and Conservation Commission use the same system. Payments made online through UniPay can take up to a week to clear the banks.

Residential permits

The town’s Residential Project Checklist lists what a house permit needs: a certificate of insurance; a Home Improvement Contractor registration for work on an existing one- or two-family home; the Construction Supervisor License of the person supervising; architectural plans, exterior elevations and structural drawings, with stamped or engineered plans where required; a certified plot plan; the homeowner form; and a preliminary HERS rater report. Because the preliminary HERS report is part of the application and a final HERS report is needed for the certificate of occupancy, a new house needs its HERS rater on board before the permit is filed. A homeowner who obtains their own permit files the Homeowner’s Affidavit. The estimated construction cost goes on the Affidavit for Estimated Cost of Construction, and subcontractors file a Sub Trade Affidavit for their share. The division’s accessory dwelling unit page and the Building Commissioner’s handout “ADUs and You” cover the by-right ADUs that state law has allowed since February 2, 2025.

Commercial permits

Commercial work has its own building permit checklist. Where the code requires a registered design professional, the Construction Control Document under 780 CMR 107.6 is part of the filing. Sprinkler permits (NFPA 13), fire alarm work and elevator work under 524 CMR all run through the division.

For tenant improvements and new commercial builds, Alliance handles commercial permit applications through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Zoning. The Building Commissioner reviews plans against the Zoning Bylaw. Under Chapter 40A and the bylaw, the Zoning Board of Appeals hears appeals of the Commissioner’s decisions and applications for special permits, variances and comprehensive permits, in quasi-judicial hearings with time limits set by state law. ZBA applications go through ViewPoint Cloud, with meeting materials on Diligent and a 2026 hearing schedule posted.
• Planning Board. Its applications are filed through the town’s OpenGov portal, westwoodma.portal.opengov.com, not through ViewPoint Cloud, so a project that needs both Planning Board and building approvals is filed on two different systems.
• Conservation Commission. Work in or near wetlands and river resource areas falls under the Wetlands Protection Act and the town’s Wetlands Bylaw, Chapter 392. All conservation filings have been online since May 10, 2019, and the commission posts its 2026 meeting dates with their filing deadlines.
• Stormwater. The Conservation Commission also acts as the Stormwater Management Authority, with its own Stormwater Management Application Form.
• Board of Health. Health permit applications are submitted online to the Health Division; septic systems are a Board of Health matter under the state’s Title 5 rules.
• Historical Commission. Its applications are listed on the town’s permitting and licensing hub, and it reviews demolition of covered older buildings under Chapter 250A.

Westwood permit costs and fees

The Building Division’s web pages do not post a schedule of permit fees, and the town code has no building permit fee chapter either. Permit fees are paid online through UniPay as part of the ViewPoint Cloud application, and the office at 781-320-1091 can give the figure for a planned job. What the town does publish about fees is listed below.

Because the town asks for both an estimated-cost and a final-cost affidavit, keep the construction budget and the final invoices together; the final figure is filed when the job closes out.

Trade permits and who may pull them

• Electrical. Issued by the Building Division and inspected by the wiring inspector or assistant wiring inspector; filed by a state-licensed electrician. The division warns that the Stretch code changes how service calculations are made on new houses and asks electricians to take care sizing services on new construction.
• Plumbing and gas. Filed by a licensed plumber or gas fitter under 248 CMR and inspected by the plumbing and gas inspector, who keeps office hours on Thursday mornings.
• Sprinkler and mechanical. Separate permits from the same division, under NFPA 13 and the 2021 International Mechanical Code; sheet metal work follows 271 CMR.

Every trade inspection is requested through the office line, not through the inspector who will do it.

How to apply for a Westwood building permit

Review, corrections and what causes delay

The division tells applicants that building permit processing can take up to 30 days, which matches the state code’s deadline in 780 CMR 105.3.1 for the building official to grant or refuse an application in writing, counted from the day it is filed. Things that can hold a Westwood file up include a missing checklist item (an insurance certificate, plot plan or HERS report), a zoning question that has to go to the ZBA with its statutory hearing timeline, a demolition of a pre-1911 or listed building that goes to the Historical Commission, and payments that have not yet cleared UniPay.

Inspections in Westwood

All inspections are booked by calling the office at 781-320-1091. The division asks applicants not to call or email inspectors with inspection requests and not to leave requests as messages on the online permit. Building inspectors are generally in the office before 10:00 am, the wiring inspector on Monday mornings and the plumbing and gas inspector on Thursday mornings, for questions rather than bookings.

Inspections follow the State Building Code’s stages for the permit type, with the electrical and plumbing and gas inspectors signing off their own work. For a new house, the certificate of occupancy at the end requires a final as-built plot plan and a final HERS report, and the Affidavit for Final Cost of Construction records what the job actually cost.

Massachusetts building code in Westwood

Westwood enforces the 10th edition of 780 CMR, the only edition in effect since July 1, 2025, and the Stretch energy code for applications submitted after January 1, 2023; the town code carries it as Chapter 251, Stretch Energy Code. FEMA’s Community Status Book lists the Town of Westwood (community 255225) as participating in the National Flood Insurance Program; its first flood insurance rate map dates from November 2, 1973 and the current effective map from July 8, 2025.

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

Westwood permit search and official resources

Each week the Building Division posts a PDF list of the residential building permit applications it has received, known as the Window Report. Applicants follow their own permits in ViewPoint Cloud; for older permits and plans, ask the Building Division or make a public records request to the town. Materials for Zoning Board of Appeals cases are published through Diligent, which helps when a past variance or special permit on a lot matters to a new project.
