Summary
Massachusetts law (MGL c.40A §9B) protects solar access rights and limits the ability of municipalities to restrict solar installations. While there is no explicit state solar access statute preempting HOA restrictions, Boston condominium associations face practical limits in prohibiting solar installations due to state zoning protections and net metering rights.
Section 9B. Zoning ordinances or by-laws adopted or amended pursuant to section five of this chapter may encourage the use of solar energy systems and protect solar access by regulation of the orientation of streets, lots and buildings, maximum building height limits, minimum building set back requirements, limitations on the type, height and placement of vegetation and other provisions. Zoning ordinances or by-laws may also establish buffer zones and additional districts that protect solar access which overlap existing zoning districts. Zoning ordinances or by-laws may further regulate the planting and trimming of vegetation on public property to protect the solar access of private and public solar energy systems and buildings. Solar energy systems may be exempted from set back, building height, and roof and lot coverage restrictions. Zoning ordinances or by-laws may also provide for special permits to protect access to direct sunlight for solar energy systems. Such ordinances or by-laws may provide that such solar access permits would create an easement to sunlight over neighboring property.
Full Breakdown
Massachusetts provides significant protections for solar energy access. MGL c.40A §3 prohibits municipalities from unreasonably regulating solar energy systems through zoning. MGL c.40A §9B authorizes municipalities to adopt solar access bylaws protecting sunlight to existing solar installations. However, Massachusetts does not have a specific statute that explicitly prohibits HOAs or condominium associations from restricting solar installations on common or individual-unit areas. Boston condominium associations may set rules regarding solar installations but must balance these against state energy policy and the practical protections of MGL c.40A. In practice, most Boston condo associations permit rooftop solar with conditions regarding installation quality, insurance, and roof maintenance. The state's SMART incentive program and net metering credits provide financial motivation for associations to approve solar. Community solar programs offer alternatives for residents in buildings where rooftop installation is impractical.
Violations & Fines
HOA restrictions that effectively prohibit solar installations may be challenged under state energy policy and MGL c.40A protections. Disputes typically go through condo association governance and civil courts. There are no municipal fines specific to HOA solar disputes.
