Oak Creek, Wisconsin Building Permit Guide

In Oak Creek, building, electrical, plumbing and HVAC permits come from the city’s Inspection Services department at City Hall, 8040 South 6th Street (414-766-7002). DSPS lists the City of Oak Creek as a delegated Uniform Dwelling Code municipality, and the city can review commercial building plans as a DSPS agent. Under the fee resolution adopted December 2, 2025, a new house is $0.40 per square foot with a $250 plan review, and the city invoices a $3,996 impact fee for each new dwelling unit.

What requires a building permit in Oak Creek?

Oak Creek’s permit pages answer the common questions project by project. For an existing house, any renovation or remodel needs a building permit, with electrical, plumbing and HVAC work on separate permits. New homes, additions and attached garages, decks, sheds and garages, pools, fences, egress windows, foundation repairs, ramps, solar panels, demolition and mobile home placement all have their own permit pages.

Drywall or insulation replacement may or may not need a permit depending on the scope, so the city asks you to call the building inspector first.

What Oak Creek decides and what the state holds

Construction standards come from the state codes, which Oak Creek enforces as a delegated city. Oak Creek decides its fees, which it evaluates every year, its zoning code, including Section 17.0414 on accessory buildings, its impact fee, and the rule that homeowners pulling their own permits must live at the address. The Plan Commission must approve new non-residential buildings, additions and exterior alterations before a building permit can be filed.

Oak Creek building department: who handles permitting

Inspection Services issues the city’s building, electrical, plumbing, HVAC, occupancy, well and tent permits, while Community Development handles zoning items such as fences, signs, home occupations and Board of Zoning Appeals cases, and Engineering handles driveways, right-of-way work and stormwater permits. On DSPS’s list of Uniform Dwelling Code agents, current as of September 24, 2026, the City of Oak Creek is delegated. DSPS’s October 19, 2026 lists show Oak Creek with a special delegation for commercial building and HVAC plan review, done by city staff, and with commercial building inspection and commercial electrical inspection delegations. The city’s plumbing page says Oak Creek does not do plumbing plan reviews, and it is not on DSPS’s commercial plumbing plan review list, so plumbing plans that need review go to the state.

Oak Creek permit types

Oak Creek accepts a number of permit applications and Plan Commission submittals online through BSAonline. An applicant who already uses BSAonline elsewhere, or who creates a new account, calls 414-766-7002 to link it to Oak Creek before applying; anything not accepted online is filed in person or by mail. Fees are printed on each application, and the application packet is reviewed by several departments, which can take up to ten business days from a complete submittal before the city emails an invoice.

Residential permits

• New one- and two-family homes: a copy of the confirmation of the state’s online UDC application to DSPS, three sets of plans to scale, heat loss calculations, a wall bracing sheet if it is not on the plans, two plats of survey showing contours, elevations and the house and driveway footprint, and the erosion control and residential occupancy applications.
• Alterations: the building permit application with existing and proposed floor plans; homeowners filing their own permit add the cautionary statement for owners.
• Sheds and garages: the shed and garage application, plans for buildings of 120 square feet or more, and a plat of survey with setbacks; Engineering may call for an erosion control application. Section 17.0414 allows two accessory buildings per lot, together no larger than 1,000 square feet (1,200 on lots over half an acre) or 75% of the house’s livable area, whichever is less, and no taller than 20 feet or the house.
• Decks: the deck application with setbacks, construction plans to scale and a plat of survey.
• Owner applicants: homeowners may pull their own building, deck, driveway, electrical and plumbing permits only if they physically live at the address.

Commercial permits

New non-residential buildings, additions and exterior alterations need Plan Commission approval before the permit is submitted, and the building plans need DSPS review, either by Oak Creek acting as the state’s authorized agent on the city’s OCSBD-118 form or directly by the state. An agent review package includes three bound sets of plans signed and sealed by the design professional, structural, energy and lighting calculations, specifications, a stake-out survey by a Wisconsin land surveyor for new buildings and additions, life-safety and code analysis sheets, high-piled storage documentation where it applies, the DSPS disproportionality form for existing buildings, an erosion control application and civil plans, and the non-residential occupancy application, with PDF copies of everything.

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

What comes before the building permit

• Plan Commission. Required first for new non-residential buildings, additions, exterior alterations and accessory buildings on non-residential lots.
• Board of Zoning Appeals. Variances, appeals and interpretations go to the board through Community Development.
• Stormwater. Development or redevelopment covered by the city’s stormwater rules needs a Storm Water Management Permit from Engineering.
• Right-of-way. Any excavation in a street, alley or other public way needs an approved right-of-way permit first.
• Driveways. New, replaced or expanded driveways, approaches and parking pads need a permit with a plat of survey, and forms and subgrade are inspected before the pour.

Oak Creek permit costs and fees

Oak Creek sets its fees by resolution and re-evaluates them every year. The current schedule is Resolution 12637-120225, adopted by the Common Council on December 2, 2025, with 2026 additions in April and May that dealt with recycling penalties and farmers market fees. Square-foot fees count all floor areas, including crawl spaces, measured to the outside walls, totals are rounded up to the next dollar, and every permit has a $60 minimum.

Worked example using the resolution: a new house with 2,200 square feet of floor area, crawl space included, is 2,200 × $0.40, or $880, plus the $250 plan examination, the state seal charge plus $5 and a $50 occupancy permit, or $1,180 plus the seal before trade permits. The city’s new-home page adds that the impact fee for new residential construction is $3,996 per unit, invoiced with the building permit, and that water and sewer charges are set by the Water Utility. State-approved commercial plans reviewed by the city cost $250 under 100,000 square feet and $500 above.

Trade permits and who may pull them

Each trade has its own application and its own inspections, and rough electrical and plumbing inspections must be scheduled before the rough building inspection can be.

• Electrical: there are separate homeowner, low-voltage and contractor electrical applications, and several can be filed online. Contractors holding a DSPS master electrician number use the contractor form; a homeowner who lives in the house may pull a homeowner permit. The minimum is $60, a new or replacement service up to 200 amps $65, and a residential solar system $50.
• Plumbing: a permit is needed to install, alter or replace fixtures, outdoor and underground plumbing, private sewage systems and backflow devices. Homeowners filing their own plumbing permit sign a separate plumbing cautionary statement and may not install outside laterals. A private sewage system or holding tank is $250 and a sanitary permit $450, both including the state’s groundwater and sanitary permit fees.
• HVAC: residential HVAC covers furnaces, fireplaces, pool heaters and wood-burning stoves; heating units and air conditioners are $60 each, and duct systems $2.25 per 100 square feet with a $150 minimum.
• Dwelling contractors: on one- and two-family work the state’s Dwelling Contractor certification and Qualifier rules apply to anyone other than the resident owner.

How to apply for an Oak Creek building permit

Review, corrections and what causes delay

Review time is counted from a complete submittal, so send every plan, survey and calculation with the application. A homeowner who does not live at the address cannot pull the permit, and commercial plans need either the city’s agent review or state approval before a building permit issues. Water service must be shut off or turned on by the Water and Sewer Utility, not by the plumber.

Inspections and occupancy in Oak Creek

Call Inspection Services at 414-766-7002 at least 24 hours ahead, with the permit number. Inspections are block scheduled in a morning window from 9 a.m. to noon or an afternoon window from noon to 3 p.m. On a remodel or new house, the rough electrical and plumbing (and HVAC on an alteration) must be scheduled before the rough building inspection, and the same order applies to finals. A deck has three inspections: post holes before the posts are set, rough framing before the decking goes on, and a final.

Silt fence must stay in place throughout a new home project. The permit closes when the final inspection passes, and new homes need the residential occupancy permit ($50 per unit) before move-in; commercial occupancy, new or a change of use, is $150.
