Massachusetts Remodeler Legislation, Codes, and Guidelines

Massachusetts Building Codes for Remodelers and Residential Renovations

Massachusetts adopts and amends the International Code Council (ICC) codes, with specific editions and state-specific amendments. The primary codes governing building and residential renovations are based on the International Building Code (IBC) and the International Residential Code (IRC). Massachusetts has also adopted the International Existing Building Code (IEBC), which is particularly relevant for renovations and alterations to existing structures.

The specific codes currently in effect are the 2020 Massachusetts Building Code (10th edition) and the 2020 Massachusetts Residential Code (9th edition), which are based on the 2018 IBC and 2018 IRC, respectively, with state-specific amendments. The 2020 IEBC is also adopted and amended for existing buildings.

The primary state agency responsible for setting and enforcing building codes in Massachusetts is the Massachusetts Board of Building Regulations and Standards (BBRS), which operates under the Division of Professional Licensure within the Massachusetts Executive Office of Housing and Economic Development.

The Massachusetts State Building Code generally distinguishes between cosmetic remodels and structural alterations based on the scope of work and its impact on the building's structural integrity, egress, fire safety, and occupancy. Cosmetic remodels, such as painting or replacing flooring, typically do not require permits or extensive code compliance beyond basic safety. However, structural alterations, including but not limited to, converting attics or basements into habitable living spaces, moving walls, altering load-bearing elements, or changing the occupancy of a space, generally require building permits, plan reviews, and inspections to ensure compliance with the adopted codes.

Demolition guidelines apply when structures or parts of structures are being removed. The specific requirements for demolition, including safety precautions, environmental considerations, and notification procedures, are outlined within the Massachusetts State Building Code and may also be subject to local municipal ordinances. Demolition permits are typically required before any demolition work can commence.
