Dodge County's Code Administration Division states the split as clearly as any county in Wisconsin: a land use permit and a building permit are two separate permits, each of which may be required. The county administers the first, ensuring compliance with the Land Use Code; each town administers the second, ensuring compliance with the state Uniform Dwelling Code.
The division manages the Land Use Code with its subdivision and comprehensive zoning district regulations and overlay districts covering environmental protection, highway setback, planned unit development, land spreading of petroleum contaminated soil, wireless communications, wind energy systems and non-metallic mining reclamation — plus the airport zoning, floodplain, shoreland protection and sanitary ordinances.
This guide covers unincorporated Dodge County. Beaver Dam, Watertown, Mayville, Horicon, Juneau, Waupun and Hartford permit their own construction. Juneau and Horicon residents must nonetheless contact the county about the airport ordinance.
Thirteen towns have adopted county zoning. Ashippun, Calamus, Elba, Emmet, Fox Lake, Hustisford, Lebanon, Leroy, Lomira, Oak Grove, Rubicon, Shields and Trenton are under the county's Land Use Code. In one recent year, the Code Administration Division oversaw the issuance and review of nearly one thousand permits.
What requires a building permit in Dodge County?
Wisconsin splits construction into two statewide instruments, and neither one is a city invention. One- and two-family homes run on the Wisconsin Uniform Dwelling Code (SPS 320 to 325), a code Wisconsin wrote for itself — the state never adopted the International Residential Code, so IRC chapter references from other states simply do not apply here. Everything that is a public building or a place of employment, including any residential building of three or more units, runs on the Wisconsin Commercial Building Code (SPS 361 to 366), which moved to the 2021 I-codes effective September 1, 2025; plans submitted on or after November 1, 2025 must comply with the 2021 editions. Under Wis. Stat. 101.65(1c) and 101.02(7r)(a), Dodge County may not enforce different technical standards — local ordinances must strictly conform to the state codes.
Typically permit required
- County land use permits, ensuring compliance with the Land Use Code
- Sanitary permits under the county sanitary ordinance
- Shoreland protection, floodplain and airport zoning approvals
- Land division approvals, including sale-to-adjacent-landowner applications
- New address assignment, based on where the driveway meets the road
- The town building permit, ensuring compliance with the Uniform Dwelling Code
Often exempt
- Projects where the county's permitting tool indicates no county permit is required — though town permits may still apply
- Anything inside a city or village, other than the airport ordinance question for Juneau and Horicon
- Buildings used for farming — exempt from the state code under Wis. Stat. 101.05(5), with farming defined by DSPS rule; a produce stand stays exempt only while the farmer raised substantially all of what it sells
- Primitive rural hunting cabins — carved out of municipal jurisdiction by Wis. Stat. 101.65(1g)
- Bed-and-breakfast establishments as defined by statute (Wis. Stat. 101.05(2))
What is actually local, and what is not
Building standards are statewide and enforced by the town. Dodge County's layer is the Land Use Code and its overlays — environmental protection, highway setback, wind energy, wireless facilities and petroleum-contaminated-soil land spreading among them — which is broader than the shoreland-and-septic role many Wisconsin counties keep.
Who handles permitting in Dodge County?
The Code Administration Division of Land Resources and Parks administers the Land Use Code, the airport, floodplain, shoreland and sanitary ordinances, and land division. Towns issue building permits. The Board of Adjustment decides appeals and variance applications, documenting the grounds for each decision to allow circuit court review.

Permit types
Residential permits
A rural house needs the county land use permit where the Land Use Code applies, the county sanitary permit on a private system, and the town's building permit under the Uniform Dwelling Code with state Dwelling Contractor credentials. The county recommends having the project staked out before submitting, since on-site inspections may be required.
How Wisconsin contractor licensing works
Wisconsin has no state general contractor license for commercial work — the city's own forms note that 2013 Wisconsin Act 20 ended state building-contractor registration on July 2, 2013. For one- and two-family work the state requires a Dwelling Contractor certification on the business and a Dwelling Contractor Qualifier on an individual, and under Wis. Stat. 101.65(1m) Dodge County may not issue a building permit to a contractor who cannot produce them; owner-occupants are exempt. Electricians and plumbers are licensed statewide by DSPS. HVAC contractors only register with the state — there is no state HVAC license — which is exactly where local rules step in. Dodge County licenses no trades; state credentials govern and the town inspector verifies them.
Commercial permits
Commercial development under the Land Use Code needs county land use approval, potentially with overlay district review. Building code plan review routes to the state or a delegated municipality; the county holds no commercial plan review delegation. The county has also considered moratoria on specific development types, including data centres in county-zoned areas.
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 sixteen or more fixtures. Overlay districts — wind energy systems, wireless communications facilities, highway setback and environmental protection among them — can attach requirements that ordinary zoning review would not surface.
Dodge County permit costs and fees
County land use fees are published with the applications; town building fees are set by the town. The county's online permitting tool is the fastest way to establish whether a county fee applies at all.
| Item | Fee or rule |
|---|---|
| Land use permit | Per the county schedule; the permitting tool identifies whether one is required |
| Sanitary permit | Under the county sanitary ordinance |
| Land division and sale to adjacent landowner | Separate county applications |
| Town building permit | Set by the town |
Even where no county permit is needed, check the town. The county advises that whether or not a land use permit is required, you should contact your town officials to see if town permits are required — the two systems are genuinely independent.
Trade permits and who may pull them
Trades are state-credentialed and permitted at town level; the county's role is land use, sanitary and land division.
Permit required
- Electrical, plumbing and HVAC — state credentials; town permits
- Private onsite wastewater systems — county sanitary permit
- Work in shoreland, floodplain or airport zones — county approvals
- One- and two-family general work — state Dwelling Contractor plus Qualifier
Typically exempt
- Projects the county permitting tool clears — subject to town requirements
- Work inside cities and villages, other than airport ordinance questions
How to apply for a Dodge County building permit
It identifies whether a county permit is required before construction starts.
Thirteen towns have; the rest zone themselves.
On-site inspections may be required as part of review.
Reviewed for compliance with the Land Use Code and any overlays.
Addresses are assigned from where the driveway meets the road.
Town permits may be required whether or not a county permit is.
Review, corrections and what actually causes delay
Dodge County's volume — close to a thousand permits a year through one division — means the process is well worn but queued. The overlays are the surprise factor: a parcel can be caught by highway setback, wind energy or environmental protection rules that a straightforward zoning check would miss.
Inspections in Dodge County
Building inspections are the town's. County activity includes on-site inspections during land use review, sanitary system oversight and code enforcement.
