Amherst, Massachusetts Building Permit Guide

Amherst’s Inspection Services department, part of Conservation & Development at Town Hall, 4 Boltwood Avenue (413-259-3030), issues building, electrical, plumbing and gas permits for the town, and all applications go through the Town’s OpenGov portal. A new house is charged $0.55 per square foot of living space on the posted fee schedule, and inspections are booked by calling the department.

Beyond construction permits, the same office runs Amherst’s residential rental permit program and the certificate of inspection cycle for multi-family, assembly and fraternity or sorority buildings, so landlords deal with it every year, not only when they build.

What work requires a building permit in Amherst?

Inspection Services’ fee schedule lists what it permits: new homes and multi-family buildings, new business, industrial, educational and dormitory buildings, alterations, renovations, additions, decks and canopies, detached sheds, carports and garages, farm buildings, fences, generators, mechanical and sheet metal work, minor site improvements such as parking lot repairs and walkways, satellite dishes, signs, solar panels, sprinkler systems, pools, temporary stages and tents, and woodstoves and chimneys. Demolition, including removing a pool, also needs a permit.

Amherst prices fences, signs and satellite dishes as their own permits, so a homeowner should not assume a small structure is free of a filing; the department’s Permit Administrator meets applicants to talk through current and upcoming projects before they apply.

What Amherst decides and what the state holds

Construction rules come from 780 CMR, the State Building Code issued by the Board of Building Regulations and Standards, which Amherst enforces but cannot amend. The Town’s own layer is its bylaws and boards: the zoning bylaw with its Zoning Board of Appeals and Planning Board, the wetlands bylaw and its regulations, the demolition delay (Preservation) bylaw, the Local Historic District bylaw, the Residential Rental Property bylaw, and the fee schedules. Section 3.48 of the General Bylaws (June 2026 compilation) still carries the Town’s original Stretch Energy Code adoption, worded around the older 780 CMR 115.AA appendix, and records no later energy-code vote; ask Inspection Services whether the Stretch or the Municipal Opt-in Specialized code applies before design. Section 3.51 holds Town-owned projects over $2,000,000 to a zero-energy standard.

Amherst building department: who handles permitting

Inspection Services administers state law and Town bylaws on land use and on the construction and occupancy of buildings. The Building Commissioner is Rob Morra, who is also Assistant Director of Conservation & Development. The department issues building, electrical, plumbing and gas permits, administers the land-use bylaws, and with the Fire, Police and Health departments enforces the rental property bylaw.

Amherst permit types and application documents

Every Inspection Services permit and license is applied for online on OpenGov, and the portal sends automatic emails from noreply@opengov.com whenever a permit changes or needs action, so applicants should add that address to their safe senders. The department’s page links lookups for checking a contractor’s Construction Supervisor License, Home Improvement Contractor registration, and electrical, plumbing, gas or sheet metal license before hiring.

Residential permits

A new one-family, two-family or multi-family building is charged by area: living space for the first unit (lower level included) at one rate, each further unit at a lower rate, and unfinished basements, garages, porches and decks at the lower rate too. Work on an existing house (alterations, renovations, additions and decks) is charged on the estimated construction cost. Rental owners need a separate rental permit, valid July 1 to June 30 and renewed by June 15 each year, with a parking plan showing every space at 9 by 18 feet on a paved surface; a late renewal adds a fee equal to the permit fee on June 16 and each month after.

Commercial permits

New business, industrial, educational and dormitory buildings are charged $0.65 per square foot. Fire alarm and sprinkler plans follow the Fire Department’s written submittal procedures, which differ for Town and UMass projects, and contractors upload the Amherst Certificate of Work Completion to OpenGov when the job is done. Places of assembly, schools, religious buildings, restaurants, day care centers, boarding houses, multi-family buildings and fraternity or sorority houses are inspected periodically under the certificate of inspection program.

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

How the demolition delay works

The applicant files a demolition application, preferably online, describing the work and giving a historical narrative of the building; Planning Department staff answer questions on this step. The Historical Commission or its designee first decides whether the building is historically significant. If it is not, no further review is needed and the demolition permit can be issued. If it is, the Commission holds a public hearing on whether the building should be preferably preserved, and either issues a Demolition Authorization or a Preservation Order that bars demolition for 12 months.

What comes before the building permit

• Zoning: uses, dimensions and parking under the zoning bylaw; special permits and variances go to the Zoning Board of Appeals and site plan review to the Planning Board.
• Wetlands: the Conservation Commission applies the state Wetlands Protection Act and Amherst’s wetlands bylaw and regulations (amended 2022). A wetland permit must arrive three weeks before the target meeting, with a separate request for a certified abutters list.
• Septic: Title 5 systems are permitted by the Board of Health: $300 per lot for perc testing, $150 per system for plan review, permit and one inspection, $125 for each later plan review, $150 per re-inspection and $200 for a Title 5 witness.
• Demolition delay: the Historical Commission reviews any proposed demolition of a building 75 years or older, including removing 25% or more of a front, back or side elevation.
• Local Historic Districts: the Local Historic District Commission, created by Town Meeting on May 21, 2012, reviews construction and exterior alterations visible from a public way inside the districts.

Amherst permit costs and fees

Inspection Services posts its fee schedules online; the building schedule is marked effective July 2014 and the plumbing schedule October 1, 2005.

Example: a new single-family house with 2,000 sq ft of living space and a 500 sq ft attached garage pays 2,000 × $0.55 = $1,100 plus 500 × $0.35 = $175, a building permit of $1,275 before trade permits.

A cancelled permit keeps a $20 fee for a basic permit or $35 for one with plans, and nothing is refunded on a permit from a previous fiscal year or more than six months old.

Trade permits and who may pull them

Electrical, plumbing and gas permits are separate OpenGov applications to Inspection Services. The plumbing fee page quotes the state rule that plumbing permits go only to licensed plumbers, and it voids a plumbing permit if work has not started within 90 days. A self-employed plumber or gas fitter must carry liability insurance with completed-operations cover, or a bond, unless the owner signs the application in its place.

An alteration touching more than 75% of a building is charged at the new-construction electrical rate.

How to apply for an Amherst building permit

Review, corrections and what causes delay

Under 780 CMR 105.3.1 the Building Commissioner has 30 days from filing to issue or refuse the permit in writing. The boards that act before it meet on fixed schedules: a wetland filing must be in three weeks before its meeting, with revisions by the prior Wednesday, and a demolition found historically significant goes to a public hearing that can end in a 12-month Preservation Order.

Amherst inspections and final approval

Book every building, electrical, plumbing and gas inspection by calling Inspection Services at 413-259-3030. Plumbing permits for new homes include up to three inspections, and further visits are charged; electrical and plumbing or gas re-inspections cost $35 and $30. The certificate of occupancy for new work follows the passed finals.

Existing buildings get their own inspections. Under the certificate of inspection program, Inspection Services periodically inspects assembly, school, religious, restaurant, day care, boarding house, multi-family and fraternity or sorority buildings, including exterior stairs and fire escapes. Rental dwellings are covered by the annual rental permit.
