Cambridge requires building and electrical permits for solar PV installations, with streamlined review for standard rooftop systems and additional review in historic districts.
Solar photovoltaic installations in Cambridge require building and electrical permits from Inspectional Services. Rooftop systems on existing residential structures generally receive expedited review under MA's streamlined solar permitting best practices. Licensed electricians and/or certified solar installers must perform the work. Roof structural capacity is verified, usually with an engineer's letter for larger systems. Electrical interconnection with Eversource requires a separate net-metering application. Historic districts (Harvard, Old Cambridge, etc.) require Historical Commission review to ensure panels are not prominently visible from the public way. The Net Zero Action Plan and Building Emissions Use Disclosure Ordinance incentivize solar, and roof-mounted solar is generally exempt from building height limits within limits.
