Hanover, Massachusetts Building Permit Guide

In Hanover, the Building and Inspectional Services office on the second floor of Town Hall, 550 Hanover Street, issues building, electrical, plumbing and gas permits, and applications go in through the Town’s OpenGov portal. Under the fees in effect since July 1, 2025, a building permit costs $15 per $1,000 of construction cost, with a $50 minimum for one- and two-family homes and $100 for commercial work; a paper application adds a $35 administrative fee.

What requires a building permit in Hanover?

Hanover is a Plymouth County town of about 15,000 people. Its Building Department reviews construction, reconstruction, repair, alteration and demolition of buildings and structures and the installation of equipment, and it also controls the use and occupancy of every building and lot in town. The Town’s fee sheets and handouts show the kinds of work that come through the counter:

What Hanover decides and what the state holds

The construction rules themselves come from 780 CMR, written by the state Board of Building Regulations and Standards, and Hanover enforces them without local changes. The Town controls the pieces around the code: the fee schedules adopted for July 1, 2025, the Zoning Bylaw (last amended at the December 8, 2025 Town Meeting), and the General Bylaws as amended through the May 4–5, 2026 Annual Town Meeting, which include a pool fencing rule, a wetlands bylaw with fixed no-build distances and a 12-month demolition delay. Neither bylaw book contains a Stretch or Specialized energy code article, so ask the office which energy compliance path a new home or addition must show.

Hanover building department: who handles permitting

Building permits come from Building and Inspectional Services, the Municipal Inspections Division of Hanover’s Department of Community Development and Municipal Inspections. That department also houses Planning, Conservation, Licensing and Health, so most of the sign-offs a project needs sit on the same floor of Town Hall. Joseph Stack is the Municipal Inspections Manager, Building Commissioner and Town Planner; an electrical inspector, an alternate electrical inspector and a plumbing and gas inspector handle the trade work.

Town Hall stays open until 8 pm on Wednesdays, the one evening each week when owners can reach the office in person after a working day.

Hanover permit types and the approvals that come first

OpenGov PLC carries applications for the Building Office, the Health Office, Community Development, Conservation and the Fire Department. To start a building permit you open hanoverma.viewpointcloud.com, scroll to the Building Department, pick the permit type and click Start; an account made on any other town’s ViewPoint Cloud site works here too.

Residential permits

Owners who will run their own job sign the Town’s Homeowner License Exemption Agreement. It covers owner-occupied one- and two-family homes where the owner supervises the work, rules out anyone who builds more than one home in two years, and warns that an owner who pulls the permit, or hires an unregistered contractor, loses access to the state home improvement arbitration program and guaranty fund. Hired builders attach their license and registration, and every applicant files the workers’ compensation affidavit; a contractor without liability insurance needs the owner’s signed Liability Waiver Form.

Pools follow a separate checklist. The Conservation Commission and the Board of Health sign the application first, the electrical permit is filed at the same time, and the department’s handout asks for a site plan with the fence, gates and pool location and for 10 feet from a septic tank and 20 feet from a leaching field. General Bylaw 6-13 requires any pool with more than 24 inches of water to sit inside a chain-link fence with openings no wider than 2 inches, or a stockade fence, at least 4 feet tall with self-latching gates.

Commercial permits

Commercial and industrial jobs use the same $15 per $1,000 rate with a $100 minimum, and multi-family buildings add a $75 inspection fee per unit. Signs are charged at $6.50 per square foot, and a certificate of inspection for a place of assembly is $75. The Fire Department reviews its own permits in the same portal.

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

What comes before the building permit

• Zoning: garages, sheds and pools go in the side or rear yard only, on a lot that already has a principal use; an accessory building over 800 square feet needs a special permit and site plan review from the Planning Board. Variances go to the Zoning Board of Appeals.
• Conservation Commission: the local Wetlands Protection Bylaw sets a 35-foot no-build setback from most resource areas for houses, paved driveways, sheds, pools, garages and barns, and 50 feet for commercial and industrial projects; wetland lines must be flagged by a professional wetland scientist and expire after three years.
• Board of Health: septic plans, building additions and pools go to the Health Office (ext. 1077) for Board approval under Title 5 and the Board’s own septic and well regulations; the Board says approvals generally take 30 to 45 days.
• Flood Plain District: the Zoning Bylaw names the Town Planner as floodplain administrator.
• Historical Commission: demolition of an old building waits for its review, described under the code section below.

Hanover building permit fees

Hanover posts each department’s fees on one Fee Schedules page. The building sheet, effective July 1, 2025, bases the permit on construction cost at $15 per $1,000 and applies the same rate to mechanical work.

Worked example: an addition with an $80,000 construction cost is 80 × $15 = $1,200 for the building permit, plus $35 if it is filed on paper rather than online. OpenGov adds its own payment charges: $2.99 plus a $0.99 processing fee on a card, or a flat $5.50 by e-check. Paying by check or cash at the Building Department counter avoids them.

Electrical, plumbing and gas permits in Hanover

Wiring, plumbing and gas permits are separate OpenGov applications filed by the licensed electrician, plumber or gas fitter, and the trade inspectors work out of the same office. Their fee sheets also date from July 1, 2025. On gas work, any application covering more than one fixture must include the $20 pressure test.

The plumbing sheet also lists a $100 plumbing fee for demolition of any kind, and both the plumbing and gas sheets double the fee for work done without a permit. Septic alarms and pumps are wired under the electrical permit at $50 and $75.

Alliance handles electrical permit applications for contractors here. More on this: who pulls the electrical permit.

How to apply for a Hanover building permit

Review, corrections and what causes delay

Every application is reviewed before any fee is charged, and the portal’s inbox lists the tasks still waiting on you, such as a missing document or a correction. Under 780 CMR 105.3.1 the building official has 30 days from the filing of an application to grant or refuse it. The usual holdups sit outside the building review: a Notice of Intent hearing before the Conservation Commission, Board of Health approval that the Board itself puts at 30 to 45 days, a Planning Board special permit for a large accessory building, or a demolition held for Historical Commission review.

Inspections in Hanover

Once the permit is issued you can request inspections from your ViewPoint Cloud account or by calling the Building Department at 781-826-5000. Keep the posted permit protected from the weather; the Town suggests a sheet protector when it hangs outside. A pool needs a final inspection by both the building inspector and the wiring inspector, and an in-ground pool also needs rough inspections from both.

Failed or extra visits cost $75 on the building side and $50 to $75 for plumbing and gas. A new building or a change of use ends with an occupancy permit ($75), and a temporary occupancy permit is also $75. Where a building needs a certificate of inspection, such as a place of assembly, the fee is $75.

Building code and local bylaws in Hanover

Hanover builds to 780 CMR, 10th edition. Its General Bylaws, approved by the Attorney General in August 2026 with the May 2026 amendments, carry the local rules that most often touch a building permit. FEMA lists Hanover as a participating community in the National Flood Insurance Program, with flood maps effective July 3, 2024.

Section 6-26, Preservation of Historically Significant Buildings, covers any building 75 years old or more (an undated building is presumed to be). The Building Inspector sends the demolition application to the Historical Commission within 7 days; the Commission decides within 30 days whether the building is significant, holds a hearing within another 30 days if it is, and rules within 14 days of the hearing. A building found preferably preserved cannot get a demolition permit for 12 months. Demolishing without a permit risks a fine of up to $300 a day and a three-year bar on building permits for the lot.

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
