Milwaukee Solar Permit Guide

Milwaukee solar projects can use an expedited residential solar permit when the system meets specific size, dwelling, roof-mount, and load criteria.

Permit takeaway

Milwaukee says all solar projects require permits, and many residential PV systems may qualify for an expedited permit that replaces separate electrical and building permits.

Zoning and placement

Historic properties or districts require special consideration before solar permits are issued.

Building and trade review

Standard solar permitting can require electrical or plumbing permits, building permits, roof documentation, drawings, panel specs, and structural information.

Call before applying when

Call before applying if the system is not flush-mounted, is 10 kW or larger, is on a historic property, adds service upgrades, or includes solar thermal plumbing.
