Do I Need a Building Permit in Massachusetts?
Massachusetts building permit rules. One state building code adopted by a state board, cities and towns may only recommend stricter standards rather than impose them, and any person may petition to amend the code.
Yes, and the code is set at state level by a board rather than by your city or town. Under G.L. c. 143 the state board of building regulations and standards adopts and administers the state building code, and a municipality that wants stricter standards must recommend them to that board rather than enact them itself.
A state board adopts the code, and its seats are named in the statute
General Laws chapter 143, § 93 establishes “a board to be known as the state board of building regulations and standards” within the division of occupational licensure, and provides that “the board shall adopt and administer a state building code.” The composition is set by statute rather than left to appointment practice: fifteen members, including the state fire marshal, the commissioner of the division of occupational licensure and the commissioner of energy resources ex officio, plus twelve gubernatorial appointees filling named seats — among them a registered architect, mechanical and structural engineers, a representative of the building trades, a commercial general contractor, “a building contractor of one or two-family homes”, a head of a local fire department, and experts in commercial and residential building energy efficiency and in advanced building technology. If you are wondering who decides a Massachusetts code question, that list is the answer.
The code is written to be uniform and performance-based
Section 95 sets the objectives the board's powers must serve, and the first is “uniform standards and requirements for construction and construction materials”, compatible with accepted engineering and fire prevention practice, energy conservation and efficiency, reductions in greenhouse gas emissions and embodied carbon, and public safety. The section then fixes the test of compliance: “in the formulation of such standards and requirements, performance for the use intended shall be the test of acceptability, in accordance with accredited testing standards.” Section 95 also directs the board toward “elimination of restrictive, obsolete, conflicting and unnecessary building regulations and requirements” and toward methods that reduce construction and maintenance cost without affecting occupant health, safety and security. A performance standard can usually be met more than one way, which is worth remembering when an unfamiliar method meets resistance.
The state code absorbs the specialized codes, including the stretch energy code
Massachusetts folds a number of separately promulgated codes into the state building code rather than leaving them alongside it. Section 96 provides that the code “shall incorporate any specialized construction codes, rules or regulations pertaining to building construction, reconstruction, alteration, repair or demolition promulgated by and under the authority of the various boards” authorised by the legislature, and names examples: “the specialized stretch energy code developed and promulgated by the department of energy resources, the state plumbing code, electrical code, architectural barriers regulations, fire safety code, fire prevention regulations, sheet metal regulations and elevator regulations.” Two consequences. Those specialized codes are part of the state building code, so they are not optional extras. And under § 97 they “shall be amended only by the respective boards, commissions, departments or agencies authorized to do so by law” — the building board does not amend them.
Any person may petition to amend the code, on a published calendar
Amendment is unusually open in Massachusetts. Section 97 provides that, apart from the specialized codes, “any person may propose amendments to the state building code.” The process runs on a schedule you can plan around: “public hearings shall be held in the city of Boston in May and November of each year”, with petitions submitted “no less than sixty days prior to the public hearing”, and any significant change to a petition triggering a further hearing. Adoption “shall occur upon an affirmative vote by a majority of the members of the board at a regularly convened meeting within ninety days of the final public hearing”. The board must then send adopted amendments to every inspector of buildings or building commissioner within a set period. If you believe a code provision is wrong, the statute gives you standing to say so.
A city or town may recommend stricter standards, not impose them
This is the provision that most changes how you should read a local requirement. Under § 98, “the board of selectmen in a town or the mayor in a city may recommend to the board the adoption of rules and regulations imposing more restrictive standards than those established by the state building code”. The decision then belongs to the state board, which may adopt such rules if it finds they are “reasonably necessary because of special conditions prevailing within such city or town” and that they conform with accepted national and local engineering and fire prevention practice, with public safety, and “with the general purposes of a statewide building code”. The board may attach conditions and may terminate the rules later. One narrow exception runs the other way: a city or town “which is not served by a municipal water system may, with the approval of the board, adopt rules and regulations with regard to fire protection systems” that are more restrictive, and if the board issues no written decision within forty-five days those rules “shall be deemed to have been approved”.
Massachusetts answers the code question at state level. The state board of building regulations and standards adopts and administers the state building code under G.L. c. 143 § 93, writes it to be uniform and performance-based under § 95, and absorbs the specialized codes — including the department of energy resources' specialized stretch energy code, plumbing, electrical, fire safety and elevator regulations — into it under § 96. Local government's role is to recommend rather than to legislate: under § 98 a board of selectmen or a mayor may ask the state board to impose more restrictive standards, and the state board decides whether special conditions justify them, with a separate route for fire protection systems in communities without a municipal water system. And if you think the code itself is wrong, § 97 lets any person petition to amend it, with hearings each May and November and petitions due sixty days ahead.
