Milwaukee Solar Permits - Resident Requirements
Milwaukee, Wisconsin residents installing rooftop or ground-mounted solar photovoltaic (PV) systems must comply with city building and electrical permit rules and state trade regulations.

Use the city permit office for submission, follow state electrical trade rules where required, and confirm fees and timelines with the Department of Neighborhood Services before starting work.
Permit triggers and basic requirements

Permit requirements commonly depend on array size, roof alterations, structural changes, and whether the installation is grid-tied or includes battery storage. Obtain zoning clearance if the project alters rooflines or setbacks.
- Permits required: building permit, electrical permit, and any applicable zoning approval.
- Plans: site plan, roof plan, panel layout, racking and attachment details, and electrical single-line diagram.
- Timing: submit plans before work begins; do not conceal wiring or attachments until inspected.
