West Allis is a fully built-out inner-ring city, and its permitting reflects a place where nearly every project touches an existing structure or the public right-of-way. The city reviews commercial plans of all sizes in-house, and it licenses the trades that work in its streets.
The Code Enforcement Department at 7525 West Greenfield Avenue regulates building and zoning codes, issues permits, schedules inspections and takes complaints, with permits available through the city's online portal alongside the counter.
This guide covers the City of West Allis. West Milwaukee, Milwaukee, Wauwatosa and Greenfield are separate authorities with their own rules — and the City of Milwaukee's trade licensing does not carry across the boundary.
Two city credentials the state does not issue. Anyone doing concrete work in the West Allis right-of-way must be licensed and bonded with the city before work begins, through the Concrete Contractor License and Bond application. Separately, any company placing facilities in the right-of-way — and any contractor installing them — must complete Utility Provider Registration before permits will issue.

Typically permit required
- New construction, additions, alterations and structural work on both tracks
- Modifications to a building or tenant space, including business build-outs
- Concrete work in the public right-of-way, by a city-licensed and bonded contractor
- Sidewalk construction, maintenance or replacement on the property
- Business occupancy — every business needs a Business Occupancy Permit, with inspections from several city departments, before opening
Often exempt
- Ordinary maintenance and finishes that do not alter structure or systems
- Work below the department's published thresholds — confirm with Code Enforcement before starting
- Buildings used for farming — exempt from the state commercial building code under Wis. Stat. 101.05(5), with farming defined by DSPS rule; a produce stand stays exempt only while at least 90 percent of what it sells was grown or produced on the farm
- Primitive rural hunting cabins — carved out of municipal jurisdiction by Wis. Stat. 101.65(1g)
- Bed-and-breakfast establishments as defined by statute — outside the commercial building code under Wis. Stat. 101.05(2), though a third floor in use or a new addition must meet the Uniform Dwelling Code
What is actually local, and what is not
The building codes are the state's and cannot be varied. West Allis's local layer sits around the edges of the building: the concrete license and bond for right-of-way work, utility provider registration, the sidewalk permit, and a business occupancy process that pulls in multiple departments before a tenant can open the doors.
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
Who handles permitting in West Allis?
Code Enforcement provides for building and zoning regulation, permits, inspections and complaints, with the building inspector determining structural soundness and compliance. West Allis holds second-class-city delegation covering commercial buildings of all sizes, and performs that plan review in-house rather than contracting it out.

Permit types
Residential permits
Houses run on the Uniform Dwelling Code, with state Dwelling Contractor and Qualifier certifications required to pull the permit. West Allis's housing stock is dense and largely pre-war, so setbacks, lot coverage and existing-structure conditions shape more projects here than in newer suburbs — check zoning limits before drawing.
How Wisconsin contractor licensing works
Wisconsin certifies dwelling contractors and licenses electricians and plumbers at state level (see Wisconsin rules). West Allis adds city credentials where work meets its streets: concrete contractors working in the right-of-way must be licensed and bonded with the city, and right-of-way facility installers must be registered before any permit issues.
Commercial permits
Commercial plans are reviewed in-house at every size under the city's delegation, submitted with the city's Plan Review Application. Tenant build-outs and space modifications need permits of their own, and the Business Occupancy Permit — with its multi-department inspections — is a separate requirement before the business opens.

Call 1-855-478-4290 →Mechanical work, and where the state reviews directly
Commercial plan review in Wisconsin is a two-step: under Wis. Stat. 101.12(3)(h) the plan approval comes first and the local permit cannot issue without it. The state review trigger is 25,000 cubic feet, plus categorical triggers at any size for schools, high-hazard occupancies and residential buildings of three or more units. At 50,000 cubic feet plans must be prepared, signed and sealed by a Wisconsin-registered design professional, with a supervising professional retained for construction observation. Commercial plumbing plans go to review at 16 or more fixtures.
West Allis permit costs and fees
Fees are published in the city's fee schedule and permits are available through the online portal. The costs that catch contractors are the ones attached to licensing and registration rather than the permit itself.
| Item | Fee or rule |
|---|---|
| Concrete contractor license and bond | Required before right-of-way concrete work commences |
| Utility provider and right-of-way contractor registration | Required before permits issue for facility placement |
| Business Occupancy Permit | Required for every business before opening; multi-department inspections |
| Building, trade and reinspection fees | Per the city's published fee schedule |
No business opens without the occupancy permit. Every business needs a Business Occupancy Permit before opening, and it triggers inspections from several city departments — start it early, because it runs on a longer clock than the build-out permit.

In-house review at every size keeps the correction dialogue local and fast. The delays in West Allis are usually licensing or occupancy: a concrete subcontractor who is not city-licensed, or a tenant who starts the occupancy permit the week they hoped to open.
