NH Solar HOA & Zoning Guide 2026

Yes — New Hampshire has no solar access law protecting homeowners from HOA solar bans. Unlike states such as California (which prohibits HOA solar bans) or Massachusetts (which limits restrictions), NH does not have any statute overriding HOA deed restrictions on solar panels. An NH HOA can legally prohibit rooftop solar if the prohibition is in the governing documents (CC&Rs or Declaration of Covenants). However, if the documents do not explicitly prohibit solar, an HOA board typically cannot unilaterally ban it without amending the governing documents through a homeowner vote.

Read your Declaration of Covenants, Conditions, and Restrictions (CC&Rs) and any Architectural Guidelines carefully. Look specifically for language about "rooftop alterations," "exterior modifications," "energy equipment," or "satellite/antenna restrictions." If solar is not explicitly prohibited, request approval through the HOA's Architectural Review Committee (ARC) with a detailed proposal including panel specs, color (black-on-black preferred in most NH HOAs), and impact on neighbors' views. Document everything in writing.

You have three main options: (1) Ground-mount solar on your lot if your lot permits it and local zoning allows (most NH rural and suburban lots can accommodate a side or rear yard ground mount outside the solar zone HOAs typically restrict); (2) Community solar through CPCNH Community Power programs — you subscribe to a share of a larger solar installation and receive bill credits without any equipment on your property; (3) Propose changes to your HOA governing documents — most NH HOAs can be amended with a supermajority vote (typically 67-75%) at an annual or special meeting.

Historic districts in NH (including parts of Portsmouth, Exeter, Concord, and others) have Heritage or Historic District Commissions that review exterior modifications. Solar panels are generally classified as exterior alterations requiring commission approval. Standards vary: the Portsmouth Historic District Commission has approved solar panels on rear and non-street-facing roof pitches but has been more restrictive on front-facing installations visible from public ways. The State Historic Preservation Office (NHSHPO) provides guidance for NH homeowners in nationally registered historic districts.

NH RSA 477:49-51 allows homeowners to create voluntary solar easements — legal agreements between neighboring property owners that guarantee solar access (i.e., the neighbor cannot plant trees or build structures that shade your panels). These are negotiated privately and recorded with the county registry of deeds. Unlike states with mandatory solar access rights, NH solar easements require mutual agreement. An easement can be valuable on heavily wooded NH lots where neighbor trees pose a shading risk.

Yes. NH towns regulate solar under local zoning, typically as a component of accessory structure rules or as a specific solar energy system permit. Most NH towns allow rooftop solar by right (no special review needed) for residential systems. Ground-mount systems often require a building permit and sometimes a zoning board of adjustment hearing. Historic districts impose additional review. New NH towns are increasingly adopting solar-friendly zoning language as part of master plan updates — check your town's current ordinance on the town website.
