Zoning & HOA Considerations
Ground-mounted solar arrays are subject to zoning setback and height restrictions in most jurisdictions. Rooftop systems rarely trigger zoning review unless in a historic district. Check with your planning department for ground-mounted installations.
If you live in an HOA community: some HOAs restrict solar panel placement, visibility, and mounting style. Many states have solar access laws that limit HOA restrictions, but rules vary. Check both your CC&Rs and state solar rights laws before installing.
