HOA Restrictions
State law, not Somerville's own code, decides this one: Massachusetts General Laws Chapter 40A, Section 3 bars any zoning ordinance or by-law from prohibiting or unreasonably regulating solar energy systems, unless a restriction is necessary to protect public health, safety or welfare. That sentence binds Somerville's Zoning Board of Appeals and Inspectional Services Department, but it does not reach a private condominium association's or HOA's own governing documents.
