Waukesha publishes the two-step more plainly than most Wisconsin cities: new construction and alterations above 50,000 cubic feet need a state plan review and a city permit, and the state review must be applied for first. Below that line, the city handles the review itself.
Building Inspection sits within City Hall at 201 Delafield Street and manages permits, inspections and violations through the eTrakit portal, with fire system plans routed separately through the Fire Department for local approval.
This guide covers the City of Waukesha. The separate Village of Waukesha, along with Brookfield, New Berlin, Pewaukee and Muskego, permits on its own — and Waukesha County issues no general building permits, so the municipality decides the counter.
The volume line decides the order of operations. The city's commercial page is explicit: new construction and alterations to buildings over 50,000 cubic feet require a state plan review and a city permit, and the state review must be applied for before city permits and plan reviews. HVAC systems in buildings over that volume follow the same path; plumbing crosses over at more than 16 fixtures. Under the line, the city reviews and permits directly.

What is actually local, and what is not
The technical code is the state's throughout; what Waukesha controls is routing. The city is a delegated agent authorized to grant state plan approval, and it channels those submittals through E-Plan Exam, a private firm authorized to review building, HVAC, plumbing, fire alarm, fire sprinkler and structural engineering plans on the city's behalf.
Wisconsin's Uniform Dwelling Code covers one- and two-family homes. Its Commercial Building Code covers public buildings, workplaces and buildings of three or more units. Local ordinances must conform to both. Wisconsin rules

Permit types
Residential permits
One- and two-family work runs on the Uniform Dwelling Code, with the state Dwelling Contractor certification and Qualifier verified before the permit issues. Inspections run footing and foundation, residential erosion control, rough framing, electrical and plumbing rough, insulation and final occupancy.
How Wisconsin contractor licensing works
Wisconsin certifies dwelling contractors and licenses electricians and plumbers at state level (see Wisconsin rules). Waukesha adds no municipal trade license of its own; the city's leverage is in review routing rather than credentials.
Commercial permits
Under 50,000 cubic feet, the city reviews and permits commercial work directly. Over that line, apply to the state first — then to the city. Plans for buildings over 50,000 cubic feet must be prepared, signed, sealed and dated by a Wisconsin-registered engineer, architect or designer under SPS 361.31(1), with a supervising professional retained under SPS 361.40 who files a written compliance statement with the department and the city at completion.

Call 1-855-478-4290 →Mechanical work, and where the state reviews directly
Commercial plans above set sizes go to the state for review first (see Wisconsin rules). Waukesha's own application materials carry the supervising-professional certification language, including the requirement to file form SBD-9720 if the professional leaves the project mid-construction.
Waukesha permit costs and fees
Fees follow the city's adopted schedule and are paid through eTrakit alongside the application. The cost that matters most on commercial work is sequencing: a state review applied for late delays everything behind it.
| Item | Fee or rule |
|---|---|
| Commercial under the volume line | City permit and city plan review |
| Commercial over 50,000 cubic feet | State plan review first, then city permit and review |
| Plumbing over 16 fixtures | State plan review plus city permit |
| Building, trade and reinspection fees | Per the current adopted schedule at filing |
Fire systems have a second address. Fire alarm and fire suppression plans must be submitted and approved locally through the Fire Department in addition to the building review — plan the two tracks in parallel rather than in sequence.
