2 rules for unincorporated Essex County, Massachusetts.
Verified from official government sources
Solar is legally protected across Essex County. Massachusetts zoning law bars any city or town from prohibiting or unreasonably regulating solar energy systems except to protect health, safety, or welfare. Installations still need a building permit, an electrical permit, and utility interconnection approval.
MGL c.40A §3
No zoning ordinance or by-law shall prohibit or unreasonably regulate the installation of solar energy systems or the building of structures that facilitate the collection of solar energy, except where necessary to protect the public health, safety or welfare.
Massachusetts protects solar from municipal zoning but not from private HOA covenants. Chapter 40A Section 3's ban on unreasonable regulation applies to cities and towns, not homeowner associations, so Essex County condo and subdivision associations may restrict panel placement through their recorded bylaws.
