Wauwatosa, Wisconsin Building Permit Guide

In the City of Wauwatosa, the Building & Safety Division of the Development Department issues building, electrical, plumbing, mechanical and occupancy permits from City Hall at 7725 West North Avenue ((414) 479-8907). The city holds its own Uniform Dwelling Code delegation from the state, so its inspectors review and inspect new houses too. You apply, upload plans, pay and follow review comments in the city’s self-service portal; a deck permit is a flat $80, and the city tells applicants to allow about two weeks for plan review.

What requires a building permit in Wauwatosa?

The city asks for a building permit for new construction, additions, alterations and structural repairs, and for changes to living space such as finished basements, kitchens and bathrooms. Its Building Permit Basics handout, updated in November 2025, lists the common cases, and the Building & Safety Division answers the doubtful ones at (414) 479-8907.

A permit exemption does not lift the code: the city says building, electrical, plumbing and zoning rules still apply, only without a permit or inspection. In a mapped floodplain even permit-free work, including a fence or a deck, needs a floodplain development permit.

What Wauwatosa decides and what the state holds

The construction standards are the state’s: the Uniform Dwelling Code for one- and two-family homes and the Commercial Building Code for everything else. Wauwatosa decides how the work is permitted and inspected, sets its permit fees, and runs its own zoning code (Title 24 of the municipal code), design review, historic preservation, floodplain ordinance and right-of-way permits. A water heater replacement needs a permit, and so does any underground pipe carrying downspout or sump pump water; solar projects need a permit, almost always an electrical one.

Wauwatosa building department: who handles permitting

The Building & Safety Division enforces the state codes and city ordinances for building construction, demolition, electrical work, plumbing, furnaces and air conditioning, signs, swimming pools, fences, erosion control and the moving of buildings. Building and electrical inspectors are assigned by district, east or west of 92nd Street. The DSPS list of Uniform Dwelling Code delegated agents (current as of 9/24/2026) shows the City of Wauwatosa as delegated in its own right, with its Building and Safety Manager as the contact, so no county or state inspector is involved in a new house here.

Wauwatosa permit types

Every permit type is requested through the same online portal, which prompts for the documents each one needs. When a job needs both a building permit and an occupancy permit, the city also wants its value of work form, describing the work in detail, with the building application.

Residential permits

• Additions, remodels and new houses need construction plans and often a land survey or site plan. Exterior changes to an existing house are reviewed by staff from photos of all sides of the home; new residential construction that needs design review goes to the Design Review Board.
• Decks need elevations and a cross section drawn at a scale of at least ¼ inch per foot, plus a survey. Attached decks need 4-foot frost footings, and no deck may cover a city easement.
• Garages and sheds need plans showing all four elevations, a survey with setbacks, and photos of the front of the home. Detached ones stay 18 inches from side and rear lines and 5 feet from an alley; accessory buildings may cover no more than 12% of the lot.
• Pools need the manufacturer’s specifications and a survey and sit at least 6 feet from lot lines; an in-ground pool needs a barrier at least 3½ feet high with self-closing, self-latching gates.
• Fences need a sketch or product sheet, the height and a survey; GIS and aerial maps are not accepted in place of a survey.

Commercial permits

Commercial projects that need design review must go before the Design Review Board, and work on non-building site features of a non-residential property, such as parking, sidewalks, lighting or landscaping, needs a Site Plan Parking Lot permit from Engineering. Commercial buildings of the sizes the state reviews need DSPS plan approval, or approval from a municipality holding SPS 361.60 delegation, before the local permit; the city’s permit page sets out the delegation levels. A new commercial building, an addition, a change of use, a new business or tenant, or a change of ownership each needs a certificate of occupancy.

For tenant improvements and new commercial builds, Alliance handles commercial building permits through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Zoning. The Plan Commission hears conditional uses, planned unit developments, land divisions and rezonings; a Certified Survey Map is needed to create a new parcel. The Board of Zoning Appeals decides variances, fence exceptions and appeals.
• Design and historic review. Owners of locally designated historic properties go to the Historic Preservation Commission, which acts as their design review board for exterior work needing a building permit.
• Floodplain. Building, filling, excavating or fencing in the 100-year floodplain needs a city Floodplain Development permit ($180 application fee).
• Site plan and right-of-way. Non-residential site work needs the Site Plan Parking Lot permit; a dumpster on a street or sidewalk needs an Engineering Services permit.
• Sewer lateral. Owners are responsible for the lateral up to and including its connection to the city main.

Wauwatosa permit costs and fees

Wauwatosa does not post a per-valuation rate table on its permit pages. Fees are set in the Fee Schedule book of the municipal code and calculated in the portal’s Fee Estimator; depending on the permit they are based on the number of units, the project value, the floor area or a flat amount, and the final figure is fixed during review. The fixed amounts the city does publish are below.

Application and plan review fees are not refunded, and the Inspection Services page notes that missed inspection appointments carry a fee. Legalizing unpermitted work adds a penalty fee to the permit fee. Engineering sets the site review escrow level by project size, from parking lot changes (Level 1) to new buildings of 20,000 square feet or more (Level 3).

Trade permits and who may pull them

Electrical, plumbing and mechanical permits are separate portal applications, and the city’s license page names the credential it expects for each trade.

• Building work on homes: every contractor working on a one- or two-family dwelling must hold the state Dwelling Contractor certification and a Dwelling Contractor Qualifier certification.
• Electrical: work that needs a permit must be done by a licensed electrical contractor with a master electrician. An owner living in the house may swap switches, receptacles, fixtures and appliances without a permit as long as the wiring system is not changed. A new dishwasher needs electrical and plumbing permits.
• Plumbing: performed by a state-licensed master or journeyman plumber; water heaters and underground storm or sump conductors are plumbing permits.
• Mechanical: furnaces, air conditioning, ductwork, gas piping, fireplaces, chimneys and exhaust systems need a mechanical permit, and HVAC work must be done by a state-registered HVAC contractor. An owner-occupant may do certain non-HVAC mechanical work after getting the permit.
• Owners doing licensed-type work: a homeowner who wants to do work normally reserved for a licensed contractor applies, with a fee, to the Board of Building and Fire Code Appeals, which decides case by case; the district inspector can meet the owner first and send the board a written recommendation.

How to apply for a Wauwatosa building permit

Review, corrections and what causes delay

The city asks for two weeks for plan review on a house project, and about one week for a complete garage or shed application that does not need Design Review. Incomplete uploads are the usual delay, and exterior changes that need Design Review Board or Historic Preservation Commission approval add time. An appeal of a Design Review Board or staff decision must be filed in the portal within 10 days, and goes to the next Board of Zoning Appeals meeting staff can schedule.

Inspections and occupancy in Wauwatosa

Ask for each inspection about three days ahead, and do not go past a stage until the inspector has given written approval. The city’s inspection guide, updated in November 2025, lists the usual stages:

• Footing: soil, forms, reinforcing and setbacks approved before any concrete is poured.
• Foundation: poured walls before the pour; block walls once cores are filled and damp-proofing, insulation and drain tile are visible, before backfill.
• Rough: after the roof, framing, fire-blocking and all trade rough-ins; no insulation or drywall before the building, electrical, plumbing and heating rough inspections pass.
• Insulation and above-ceiling: before walls and ceilings are covered.
• Final: before the building is used.

A new single-family house or duplex needs an occupancy permit, and so does a commercial space for a new building, owner, tenant or use. The occupancy inspection is done by every trade: building, plumbing, electrical and the fire department.

Wisconsin building code in Wauwatosa

Wauwatosa enforces the state’s Uniform Dwelling Code under its own DSPS delegation and applies the Commercial Building Code to other buildings, alongside its zoning code (Title 24) and property maintenance rules. FEMA’s Community Status Book lists Wauwatosa (community 550284) as participating in the National Flood Insurance Program with a current effective map dated October 24, 2024; the city’s own floodplain page still describes the FEMA maps it adopted in 2008, together with an April 2022 conditional map revision for the Menomonee River, so ask Planning which map governs your lot.

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

Wauwatosa building permit FAQs

Do I need a permit for a shed in Wauwatosa?

Only if it is larger than 100 square feet or taller than 12 feet; a smaller shed still has to sit 18 inches from side and rear lines and outside the front yard.

How much does a deck permit cost?

A flat $80. You need a permit if the deck is attached, serves an exterior door or is more than 2 feet above grade, and the city asks for about two weeks to review it.

Can I put up a fence without a permit?

Yes, a side-yard fence up to 4.5 feet or a rear-yard fence up to 6 feet away from streets, alleys and non-residential land. Front-yard fences are limited to 3 feet, need a permit and go to design review.

Do I need a permit to re-roof?

Not when the new roof matches the old style. Changing the material, for example from shingles to metal, needs a building permit and staff review of the exterior change.

Can I do my own electrical or plumbing work?

Permitted electrical and plumbing work must be done by licensed contractors. An owner-occupant may replace fixtures, switches and receptacles without changing the system, and can ask the Board of Building and Fire Code Appeals to allow more.

Does a new house need an occupancy permit?

Yes. A new house or duplex is inspected for occupancy by the building, plumbing and electrical inspectors and the fire department before anyone moves in.

What happens if work started without a permit?

The owner is responsible. Work started before the permit was issued may pay a double fee, and work done without one needs a permit, inspections and possibly opened walls.
