780 CMR (Mass Building Code) requires a building permit for retaining walls over 4 feet from footing to top. Walls supporting surcharge or over 4 feet need engineered plans stamped by Mass-licensed PE. Setbacks per local zoning.
Under 780 CMR (Massachusetts State Building Code, 9th edition) R105.2, retaining walls not over 4 feet measured from the bottom of the footing to the top of the wall and not supporting a surcharge are permit-exempt. Walls over 4 feet, or any wall retaining a surcharge (driveway, structure, or sloped soil above), require a building permit and engineered design sealed by a Massachusetts-licensed Professional Engineer. Fall River, New Bedford, and Taunton require drainage details, soil-bearing assumptions, and often geotechnical input for taller walls. Zoning setbacks apply β typically walls cannot sit on the property line without written neighbor consent and must respect side-yard and front-yard requirements of the underlying district.
Unpermitted wall over 4 ft: stop-work order, engineered review required, fines $200 to $1,000 plus potential demolition. Failure to address drainage causing neighbor damage: civil liability plus code enforcement.
