City permitting reference
How permitting works in Somerville
Somerville building permits are issued by the Inspectional Services Department (ISD) under the Massachusetts State Building Code (780 CMR), 9th Edition. The city has several active overlay districts — Union Square, Assembly Row, East Somerville, and Boynton Yards — where the SomerVision 2040 Plan and form-based rules add design and planning review steps. ADUs have been allowed city-wide since the 2022 state law. All permit applications flow through the Accela Citizen Access portal.
