Full Breakdown
Under M.G.L. Chapter 40A Section 3, no zoning bylaw may prohibit or unreasonably regulate solar energy systems except where necessary to protect public health, safety, or welfare. Massachusetts adopted SolarAPP+ in many communities for streamlined residential rooftop solar permits. Building permits follow 780 CMR. Aesthetic restrictions cannot effectively prohibit solar. Net metering is governed by M.G.L. Chapter 164.
