Full Breakdown
The accessory-use table at West Allis Revised Municipal Code § 19.35 lists 'Solar Energy System' with a 'P' (Permitted) designation across all thirteen zoning districts, from RA-1 to SF, meaning solar panels are allowed by right as an accessory use anywhere in the city, unlike a wind energy system, which the same table marks as a conditional use. Chapter 19 sets no separate criteria section for solar energy systems in § 19.36, so no additional zoning-level conditions apply beyond the underlying district's normal building and yard standards. A building permit is still required for the installation itself under the state-adopted building code.
Violations & Fines
Because solar energy systems are a by-right permitted use, the main zoning risk is skipping the required building permit for the installation, or mounting panels in a way that exceeds the district's building height or yard limits.
