Wrentham, Massachusetts Building Permit Guide

In Wrentham, the Department of Inspections at 350 Taunton Street (508-384-5421) issues building, electrical, plumbing, gas and sheet metal permits, and applications are made through the Town’s OpenGov portal. Work on a one- or two-family home is charged $13 per $1,000 of the contract with a $100 minimum, commercial work $18 per $1,000 with a $200 minimum, and new construction follows the Stretch Energy Code the Town adopted effective July 1, 2022.

What requires a building permit in Wrentham?

The department’s rule is short: a permit is required for any type of construction or for installing an accessory structure, and fines follow for work done without one. Its fee sheet for one- and two-family homes lists the usual jobs in this town of about 12,500 people (Census estimate, 2025): new homes, renovations, additions, roofing, siding, windows and doors, detached structures, solid-fuel stoves, pools and hot tubs, solar arrays, structure demolitions and fences over 6 feet. Heat pumps are charged per unit. Separate mechanical (sheet metal), wiring, plumbing and gas permits cover the trade work.

What Wrentham decides and what the state holds

The State Building Code, 780 CMR, comes from the Board of Building Regulations and Standards and is not something Wrentham can amend. Local choices are the fee sheets, the Zoning Bylaw (Chapter 390 of the Town Code), the wetlands bylaw (Chapter 375), the historic buildings demolition bylaw (Chapter 297) and the Stretch Energy Code (Chapter 360). The department also enforces zoning: the Building Commissioner is the Zoning Enforcement Officer.

Wrentham building department: who handles permitting

The Department of Inspections handles building inspections, code and zoning enforcement, electrical and plumbing inspections and the sealing of weights and measures. John Naff is the Building Commissioner and Certified Building Official. A plumbing and gas inspector and a wiring inspector, each with an assistant, handle the trades.

The scanned fee sheets’ letterhead gives 508-384-5521; the department’s web page and its demolition instructions give 508-384-5421, the number used here. The department’s permit sheet says permits are applied for by a licensed building contractor, plumbing contractor (including lawn irrigation), gas fitter or electrical contractor, and it also posts the homeowner license exemption form for owners who qualify under the state code.

Wrentham permit types and the approvals that come first

The department’s forms page lists a full residential application (construct, repair, renovate, demolish), a short form, a commercial application, an amendment form, and forms for pools, tents, signs, solid-fuel appliances, sheet metal, gas and electrical work. Its checklist spells out what must come in with a building permit, and many of the items are sign-offs from other departments. The same OpenGov portal has separate categories for the Fire Department, Health, Conservation and Public Works, so applications to those offices sit in the same portal, including the Fire Department’s request for a smoke and carbon monoxide detector inspection.

Residential permits

For a house project, the checklist asks for three sets of plans (one at 11 by 17 inches) plus a PDF copy, a Fire Department plan review request with a $50 fee, and a certified plot plan stamped by a land surveyor for any footprint change or new structure. Lots in a flood plain need certified elevations from a land surveyor. Board of Health approval is needed for any footprint change or added room, along with a water well report or a Water District approval letter, a Fire Department smoke detector permit, and DPW approval for water service or driveway work. The applicant adds the workers’ compensation affidavit, a certificate of disposal compliance, an insurance certificate, the contract signed by the owner and the Home Improvement Contractor, copies of the Construction Supervisor License and HIC registration, and the energy compliance report. Every permit needs the homeowner’s email address.

Commercial permits

Commercial, industrial and three-plus-unit residential buildings pay $18 per $1,000 of contract with a $200 minimum, the Fire Department review fee is $100, and projects that need professional design use the initial and final construction control documents. Existing buildings that need periodic inspection file a certificate of inspection application: three- and four-family houses pay $100 a year, apartment buildings and hotels $200, and liquor licensees $100 to $150 depending on occupant load.

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 Land Use Office (Office of Planning and Economic Development, 508-384-5441) at Town Hall, 79 South Street, serves the Zoning Board of Appeals, Planning Board, Conservation Commission and Community Preservation Committee. Town Hall is open Monday, Wednesday and Thursday from 8 am to 4:30 pm and Tuesday until 7:30 pm, and is closed on Fridays. Recorded copies of any variance or special permit go in with the building application.
• Conservation Commission: work near wetlands needs a Notice of Intent or other filing under the state Wetlands Protection Act and Chapter 375; the Conservation Agent works from the same Land Use Office.
• Board of Health (Title 5): septic design, repairs and Title 5 reports go through the Board of Health (508-384-5480), whose public health director is also its environmental health agent; its approval is needed for any footprint change or added room.
• Floodplain: the Town’s floodplain guide explains Special Flood Hazard Areas and how owners can seek a Letter of Map Change from FEMA.
• Historical Commission: buildings 50 years or older go to the Commission before demolition (see below).

Wrentham building permit fees

The fee sheets posted on the department’s Fee Schedule page carry no adoption date. They price residential work by the contract amount, so the department asks for the signed contract with the application.

For a commercial HVAC job with a $30,000 construction cost, the sheet metal permit is $200 plus 2% of $30,000, or $800. A trailer used as emergency temporary housing or as a construction office is $100 for 90 days, and the Building Commissioner may approve a further period for $50. A replacement permit card costs $100 and a permit renewal $150. The fee sheets also warn that every violation of 780 CMR can draw a fine of $1,000 per day under state law.

Trade permits and who may pull them

The wiring inspector and the plumbing and gas inspector issue and inspect their own permits; plumbing permits cover lawn irrigation, and a new LP gas service also needs a Fire Department permit. Wiring fees are set by the number of inspections a job needs.

A new bathroom and laundry with eight plumbing fixtures in a house would be $140 for the first six and $40 for the other two, or $180. Electricians, plumbers and gas fitters hold state licenses; building permits go to a CSL holder, with HIC registration and a signed contract for home improvement work.

How to apply for a Wrentham building permit

Review, corrections and what causes delay

780 CMR 105.3.1 requires a decision on a complete application within 30 days of filing, and Wrentham’s checklist says the same: the office has 30 days to review a full application and processes files in the order received. It names the three causes of delay itself: missing, inaccurate or illegible information; approvals still needed from other departments, boards or permit granting authorities; and the volume of work in the office when the application arrives.

Inspections in Wrentham

Building inspections are requested from the Department of Inspections; electrical inspections use the department’s electrical inspection request form. Wiring permits include a set number of visits (three for a new dwelling, two for an addition), and each extra visit costs $40. A failed inspection that must be repeated costs $75 in every trade. Pools and hot tubs need both a building permit and a $200 wiring permit, and the department posts swimming pool and deck requirement sheets alongside its ADU guidance. Final sign-off depends on the Fire Department’s smoke detector permit as well as the building and trade finals.

Wrentham building and energy code

Wrentham enforces the 10th edition of 780 CMR with the Stretch Energy Code, which the November 15, 2021 Special Town Meeting adopted as Chapter 360 of the Town Code with an effective date of July 1, 2022; the Building Commissioner enforces it. The Historic Buildings bylaw (Chapter 297) reaches buildings 50 years old or older. The Building Commissioner sends the demolition application to the Historical Commission within seven days, and the Commission has 30 days to decide whether the building is significant. If it is, no demolition permit issues for 12 months from the date of the application unless the Commission reports that the owner made a reasonable but unsuccessful effort to find a buyer or preserver, or agrees to conditions. Demolishing in disregard of the bylaw blocks building permits on the site for three years, and appeals go to the Zoning Board of Appeals. The department’s demolition process sheet also requires a utility release, one week’s written notice to adjoining owners, an asbestos report filed with MassDEP on form BWP AQ 06, a Conservation sign-off and a pest control report. FEMA lists Wrentham as a participating community in the National Flood Insurance Program, with flood maps effective 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
