Do I need a permit for retaining wall construction in Brockton?
It depends. Whether retaining wall construction needs a permit in Brockton comes down to the details of your project.
Retaining walls not over 4 feet tall, measured from the bottom of the footing to the top of the wall, are exempt from a building permit unless supporting a surcharge (780 CMR 51.00 R105.2 item 3). Where a construction supervisor is required, the supervisor must be on site to approve construction of retaining walls over 4 feet in height above grade (780 CMR 110.R5.2.12). Altering a bank, wetland, or land subject to flooding requires a conservation commission filing and an order of conditions (M.G.L. c. 131, § 40).
