Milford, Massachusetts Building Permit Guide

In Milford, the Department of Inspections issues building, plumbing, gas and electrical permits and also acts as the zoning office, with applications going through the town’s CitySquared online permitting system. Under the fee schedule the Select Board approved on June 9, 2025, residential building permits cost $9 per $1,000 of construction cost ($75 minimum) and commercial permits $10 per $1,000 ($100 minimum).

What requires a building permit in Milford?

Milford’s fee schedule shows the residential work the department permits: new houses, renovations, additions, decks, roofing, siding and windows, solar and energy storage, demolition, swimming pools, wood and pellet stoves and home occupations. Commercial work adds signs, and every job with wiring, plumbing or gas needs its own trade permit.

Zoning still applies to work that needs no permit. Fences may go right up to the lot line with either side facing in, but a fence that blocks the view is limited to 3 feet 6 inches within 20 feet of the street and 6 feet elsewhere. Sheds over 120 square feet must meet full side and rear setbacks: 10 and 15 feet in the RA district, 15 and 25 feet in RB and 20 and 30 feet in RC; sheds and pools of 120 square feet or less use half those distances, and a pool on a corner lot must be 30 feet from both streets.

What Milford decides and what the state holds

All construction follows 780 CMR, the State Building Code issued by the Board of Building Regulations and Standards. Milford sets its own permit fees by Select Board vote, its Zoning By-Law (amended through October 20, 2025) and its general by-laws, such as the rule that anyone digging in a street needs a written permit from the Highway Surveyor. The town’s by-law compilation and building pages record no Stretch or Specialized energy code vote; the residential application asks for energy code compliance as part of the plans.

Milford building department: who handles permitting

The Department of Inspections is led by John Erickson, who serves as both Building Commissioner and Zoning Officer, with local building inspectors and separate plumbing and electrical inspectors. It issues building, plumbing, gas and electrical permits, enforces the zoning by-laws and applies the state Architectural Access Board rules.

The town has warned of fake emails and texts that pose as Planning and Engineering staff and demand permit or zoning fees. Milford never asks for payment by wire, cryptocurrency or payment app, or by email alone; call 508-634-2317 to check a request.

Milford permit types

Besides the residential and commercial building permit applications, the department posts applications for a certificate of occupancy, a certificate of zoning compliance, a periodic safety certificate of inspection, a home occupation and sheet metal work, plus contractor affidavits for completed HVAC, roofing, siding and window, solar and weatherization jobs and initial and final construction control documents.

Residential permits

Homeowners may apply for work on property they own and occupy; all other permits are pulled by licensed contractors. An owner who files under the homeowner exemption signs the town’s eligibility affidavit (revised August 26, 2025), which repeats the state code’s definition: a person who builds more than one home in two years is not a homeowner, and an owner who hires help must supervise the work. A certified plot plan from a registered land surveyor or civil engineer is required for new construction, any vertical or horizontal addition and any new or replacement deck, stairs or porch, even when the replacement is smaller. Plans larger than 8.5 by 14 inches must be submitted electronically. Accessory dwelling units are allowed with Planning Board site plan review under section 3.19 of the Zoning By-Law, up to half the main house’s floor area or 900 square feet, whichever is smaller, with one extra parking space unless the lot is within half a mile of a transit station; short-term rental of an ADU is prohibited.

Commercial permits

Commercial building permits are $10 per $1,000 with a $100 minimum, and commercial wiring, plumbing and gas permits are each 2% of the job cost with a $100 minimum; the trade sheets treat multi-family buildings as commercial. Buildings that need periodic safety inspections apply for a certificate of inspection on the town form. Signs follow section 3.9 of the Zoning By-Law, summarized in a sign by-law handout on the Regulations page, and a business run from a home needs a $75 home occupation permit under the town’s home occupation regulations. Dividing land into lots that already have the required street frontage uses an Approval Not Required plan, at $200 plus $200 for each new lot.

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

What comes before the building permit

• Zoning and site plan review. New buildings or additions for uses listed as needing site plan review in section 2.3 must include a site plan by a registered land surveyor, engineer or architect for Planning Board review; approved site plans expire after three years. Under the Planning Board fee schedule effective January 20, 2026, site plan review costs $300 for up to one acre plus $100 for each added acre, a waiver of site plan review $200, an amendment $250 and a Planning Board special permit $500 plus the legal notice. Special permits and variances go to the Zoning Board of Appeals by petition, with a Planning Board recommendation.
• Sewer or septic. The building page asks for a sewer permit from the Sewer Commissioners or a septic system plan approved by the Town Engineer and Conservation Commission; septic design follows Title 5. The Board of Sewer Commissioners’ connection permit application lists the owner, building contractor, licensed drainlayer, building size, bedrooms and every plumbing fixture, and the owner must give the Sewer Department director at least 24 hours’ notice to inspect the connection before any of it is covered.
• Conservation Commission. Any land disturbance in a resource area under the Wetlands Protection Act or Rivers Protection Act needs a Notice of Intent or Request for Determination of Applicability; the legal ad fee is $100 for resident RDAs and $200 otherwise, and a certificate of compliance is $50.
• Streets. Digging in a street, sidewalk or public way needs a written permit from the Highway Surveyor, with a fee of $10 to $200.

Rental housing has one more local step: under Article 37 of the Board of Health rules, no unit may be rented until the owner registers it with the Board of Health, which sets how many people it may house and issues a certificate to post in the unit; owner-occupied units are exempt. The Historical Commission runs the town museum and records; no historic district review or demolition-delay by-law appears in the town’s by-law compilation.

Milford permit costs and fees

The Select Board approved separate building, wiring, plumbing and gas fee sheets on June 9, 2025, effective July 1, 2025. Building fees are charged on construction cost, and a certificate of occupancy is included in the permit fee.

For example, a $48,000 addition to a house costs $432 for the building permit (48 × $9). A bathroom remodel with three plumbing fixtures costs $125 for the plumbing permit ($75 plus two at $25). For the plumbing fee, a sewer connection, backflow preventer, boiler connection or piping repair each count as a fixture; for gas, a propane tank and its trench each count as one.

Trade permits and who may pull them

Only licensed plumbers may apply for plumbing or gas permits in Milford, and wiring permits go to licensed electricians for hire, with an exception for communications wiring that is exempt from licensing. The homeowner route applies only to the building permit.

• Electrical: 508-634-2323; underground, rough and final inspections.
• Plumbing and gas: 508-634-2314; underground, rough and final inspections, with permits counted per dwelling unit.
• Sheet metal: a separate sheet metal application for duct work by licensed sheet metal workers.

How to apply for a Milford building permit

Review, corrections and what causes delay

The town’s application says review averages about two weeks because of heavy volume and slows when files are incomplete. The state rule in 780 CMR 105.3.1 gives the building official 30 days from filing to act. The application treats a file as complete, and ready for review, only when the construction documents, specifications, fee and any other required items, such as the certified plot plan and the insurance certificate naming the town, are all included.

Inspections in Milford

Once a permit is issued, the permit holder is responsible for scheduling every required inspection. Building inspections cover the foundation where there is one, rough framing, insulation and a final; plumbing, gas and electrical work each need underground, rough and final inspections. A reinspection costs $50, and inspections after hours cost $75 an hour, scheduled and paid in advance.

At the end of the job, the owner applies for a certificate of zoning compliance and, where the work calls for one, a certificate of occupancy before occupying or continuing to occupy the building. The certificate of occupancy carries no separate charge.
