Solar installations in Somerville need ISD building and electrical permits. Most rooftop systems qualify for expedited review and are allowed by right.
Rooftop solar photovoltaic systems are allowed by right in all Somerville zoning districts under the state Green Communities mandate and MGL c.40A s.3, which prohibits local zoning from unreasonably restricting solar access. Installers must pull a building permit and an electrical permit from Somerville Inspectional Services; most residential systems up to 10 kW qualify for expedited review consistent with the MA Board of Building Regulations expedited solar checklist. Structural review is required if the array adds more than 5 psf of load. Utility interconnection with Eversource uses the standard Schedule Z application. Ground-mount arrays need a full zoning review and setback compliance. Historic district properties need Somerville Historic Preservation Commission approval, which typically requires rear or low-visibility placement.
