2 county-level rules, plus city-specific rules for 1 city in Oakland County, Michigan.
Verified from official government sources
Residential rooftop solar in Oakland County is permitted at the city/township level under each jurisdiction's zoning ordinance plus state building code. A building permit (electrical and, often, structural) is required from the local building department. Most communities allow rooftop solar as an accessory use in all districts subject to height, setback, and screening standards; some require zoning review for ground-mount systems.
Effective April 1, 2025, Michigan's Homeowners' Energy Policy Act (2024 PA 68, codified at MCL 559.301 et seq.) forbids Oakland County HOAs and condominium associations from banning rooftop solar. Any HOA provision that prohibits — or has the effect of prohibiting — a solar energy system is 'invalid and unenforceable as contrary to public policy.' HOAs may still adopt reasonable placement and aesthetic rules through a written solar energy policy, but cannot increase system cost by more than $1,000 or reduce output by more than 10%.
