Solar PV requires a building and electrical permit under 780 CMR and 527 CMR 12. The MA Solar Access Law, MGL c.40A s.3, protects installations from zoning bans.
Rooftop and ground-mount solar projects in Middlesex County require a building permit under the MA State Building Code (780 CMR) and an electrical permit under the MA Electrical Code (527 CMR 12, which adopts NFPA 70 with amendments). Most cities and towns offer streamlined residential solar permitting aligned with the SolSmart and SolarAPP+ frameworks. Under MGL c.40A s.3, municipalities cannot prohibit or unreasonably regulate solar energy systems; restrictions must be necessary to protect public health, safety, or welfare. Interconnection to Eversource or National Grid follows the Massachusetts DPU interconnection tariff and SMART program rules.
