Germantown, Wisconsin Building Permit Guide

In the Village of Germantown, Building Inspection Services in the Community Development Department at Village Hall, N112 W17001 Mequon Road (262-346-4460), issues every building, electrical, plumbing and HVAC permit; SAFEbuilt WI staff do the permit processing, plan review and inspections. A new house is charged $0.44 per square foot under the 2026 fee schedule plus fixed fees, the village’s 2026 impact and utility connection fees total $8,588 per home inside the water and sewer service areas, and work started before the permit costs triple.

What requires a building permit in Germantown?

The village’s rule is that every building, out-buildings and garages included, needs a permit before it is built, and that changes to or installations of electrical, plumbing, HVAC systems and driveways need a permit before work begins. Its residential handout lists the common projects.

Projects not on the list may still need a permit; the department asks owners to call 262-346-4460 when unsure. A subdivision’s architectural approval and a homeowners association’s approval are separate from the permit.

What the village decides and what the state holds

The village administers its own zoning code, its shoreland, wetland and floodplain zoning and its 2050 Comprehensive Plan, and its Community Development Department supports the Village Board, Plan Commission and Board of Zoning Appeals. The construction standards are the state’s: the Uniform Dwelling Code for one- and two-family homes and the commercial building code, which Germantown enforces itself because DSPS has delegated commercial building, HVAC, plumbing, fire suppression and fire sprinkler plan review and inspection to the village since February 25, 2021.

Germantown building department: who handles permitting

Building Inspection Services oversees new construction and alterations of homes and commercial buildings and the installation of plumbing, electrical and heating and air conditioning systems. The village contracts SAFEbuilt WI for permit processing, plan review and inspections, and the state’s Uniform Dwelling Code list, current as of September 24, 2026, shows the Village of Germantown as a delegated municipality. The Town of Germantown is a separate municipality with its own entry.

Card payments (Visa, Mastercard or Discover) are accepted at the inspection window in Village Hall, but not over the phone.

Germantown permit types and application documents

The 2026 building permit application covers one- and two-family, multi-family, commercial and agricultural work. It asks for the description of work, the size, height, zoning district, setbacks, estimated cost, the owner, and the contractor’s Dwelling Contractor and Qualifier numbers with expiration dates. By signing, the applicant agrees to get inspection results by email, as SPS 320.10(4) allows.

Residential permits

A new one- or two-family home needs a complete set of plans with elevations and a materials cross section, energy worksheets from the heating contractor or an energy consultant, the makeup and combustion air worksheet where open-combustion appliances are used, a lot survey with the house staked, setbacks, driveway location and elevations to the village datum including the curb stop, the state UDC permit application completed on the DSPS eSLA website, and an erosion control permit application. At submittal the village wants three sets of plans (one on 11-by-17 paper) with roof, siding and trim colors noted, five copies of the survey and two energy worksheets. There is no fee at submittal; the house permit includes the plumbing, HVAC and electrical permits but not the outside water and sewer permit. Additions and accessory buildings need two sets of plans and a survey.

Commercial permits

Commercial building and occupancy permits need sign-off from both Planning and Engineering, and buildings over 50,000 cubic feet need state-approved plans. The submittal is the building permit application, two sets of approved plans and one more for the Fire Department, an erosion control application with two erosion control plans, the sewer and water connection data form, a driveway permit application, a Fire Department inspection application and a $20,000 occupancy bond in cash or a letter of credit. Under its delegation the village can give the DSPS-authorized plan review itself.

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

• Planning approvals. Contact the Planning Department about village approval requirements; most subdivisions also require architectural approval.
• Septic. On a private system, a sanitary permit or approval from Washington County comes first, for new homes and for exterior projects.
• Driveway. An Engineering Department permit; in the A-1, A-2 and Rs districts a driveway is 12 to 25 feet wide at the road and at least 5 feet from the side lot line, and on new construction the curb stop must be at least 5 feet from it.
• Erosion control. An Engineering Department permit for every new home.
• Fences. Up to 6 feet in rear and side yards and 4 feet in front (up to 6 with Plan Commission approval), at least 2 feet from the right of way, and not on an easement without the Plan Commission.

Germantown permit fees (2026)

The village’s 2026 Building Inspection Fee Schedule, revised December 15, 2025, sets the fees below, and a $4.23 technology fee is added to every permit. More than one fee usually applies: the schedule says a new home is charged a base construction fee, plan review, property record maintenance, zoning compliance, occupancy, erosion control and the state building permit seal, plus the HVAC, electrical and plumbing fees.

For a new home the fixed charges on the schedule add up to $957.39 before any per-square-foot fee: plan review $238.02, property record maintenance $211.57, zoning permit $185.13, erosion control $185.13, the state seal $68.77 and one occupancy permit $68.77. The construction, HVAC, plumbing and electrical fees are then figured on the home’s area, and the technology fee is added to each permit.

Impact and utility connection fees for 2026 are separate: $1,003 water, $1,311 park and recreation, $171 fire, $148 police, $711 library and $5,244 sewer, $8,588 in all for a home. The water and sewer fees apply only inside the village’s water and sewer service areas, and the sewer fee rises 3.25% every January 1. Commercial buildings pay $1,003 water and $5,244 sewer per REC (the schedule’s connection unit), and fire and police impact fees of $0.63549 and $0.2809 per $1,000 of construction cost.

Trade permits and who may pull them

Germantown issues its own electrical, plumbing and HVAC permits, with separate application forms for each, and its inspectors check the work. On a new house those permits are rolled into the building permit cost; on other projects the building permit form warns that separate electrical, plumbing and heating permits may be required. Under the village’s DSPS delegation, commercial HVAC, plumbing, fire suppression and sprinkler plans are reviewed locally too.

• Contractors. A contractor pulling permits for work on one- and two-family homes must hold both the state Dwelling Contractor certification and the Dwelling Contractor Qualifier certification, and the village form records both numbers; an owner-occupant building their own home is exempt under state law.
• Electrical fees. $52.90 for a service up to 200 amps, $10.58 for each further 100 amps, $77.25 for a home vehicle charger and $105.79 for in-ground pool wiring.
• Plumbing fees. $10.58 a fixture for remodels and replacements, $52.90 for the first 100 feet of sewer or water line and $0.49 for each foot beyond.
• Plumbing tests. The forms list includes an affidavit of plumbing testing and a compliance statement.

How to apply for a Germantown building permit

Review, corrections and what causes delay

Applications are reviewed first come, first served, and review time depends on the project and the line of applications ahead of it. A new-home file is held up by missing pieces such as the energy worksheets, the staked survey with datum elevations and curb stop, or the eSLA state application with contractor credentials. Commercial permits wait for Planning and Engineering sign-off and the $20,000 occupancy bond. To talk a plan through with an inspector, come between 8 and 10 a.m. on a weekday.

Inspections and occupancy in Germantown

Inspections must be scheduled before 4 p.m. for the next day, at 262-346-4460. A new home goes through footing (with the surveyor’s recertification of the footings), foundation (before backfill, with waterproofing and drain tile done), an optional service inspection, rough electrical, rough under-floor and rough plumbing, drain tile, rough framing, insulation, exterior plumbing for the sewer and water laterals (the curb stop ending 6 inches above grade), final electrical, final plumbing and the final inspection.

The water meter and house numbers must be in before the final; the occupancy permit is issued at the final inspection, and moving in earlier brings the ordinance’s penalties. Inspectors will not enter a building that has belongings in it without an escort. The re-inspection fee, charged from the third inspection on, is $68.77, as is a missed call for a required inspection. Each inspection gets a written report, kept in the property file as a history for current and future owners.

The village has no certificate of compliance program, so it requires no compliance certificate before a property changes hands.
