Grant County combines conservation, sanitation and zoning in a single department, and its zoning permit process carries a rule that decides whether some rural parcels can be built on at all: a land-locked parcel needs an easement at least 66 feet wide, or one that existed before the town adopted comprehensive zoning.
The department administers the county's comprehensive zoning ordinance, the sanitary permit process and shoreland and floodplain regulation, and reports annually to the state agriculture department on acreage rezoned out of the farmland preservation district.
This guide covers unincorporated Grant County. Platteville, Lancaster, Boscobel, Fennimore, Cuba City and Dickeyville permit their own construction; in the towns, each town holds its own state Uniform Dwelling Code delegation and issues the building permit.
Access is a zoning question here. Before a zoning permit will issue on a land-locked parcel, the easement must be at least 66 feet wide, or must have existed before the town adopted comprehensive zoning. Separately, where a private road serves single-family dwellings, no zoning permits issue for additional dwellings until the private road has been converted.

Typically permit required
- County zoning permits under the comprehensive zoning ordinance
- Sanitary permits through the department's sanitary permit process
- Shoreland zoning approvals — applying to all land within 300 feet of a navigable waterway, measured from the ordinary high water mark
- Floodplain approvals, in zones defined by the federal flood mapping programme
- Farmland preservation rezoning where agricultural land is being converted
- The town building permit, where the town requires one
Often exempt
- Anything inside a city or village, which permits independently
- Projects the department confirms fall outside county permit requirements
- 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
Building standards are statewide. Grant County's layer is agricultural and access-focused: the A-1 agricultural district covers predominantly rural land where soil or site characteristics limit use, farmland preservation rezoning is tracked and reported annually to the state, and easement width can be decisive on a rural 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

Permit types
Residential permits
A rural house needs the county zoning permit, a sanitary permit where a private system is involved, and the town's building permit under the Uniform Dwelling Code with state Dwelling Contractor credentials. Access and easement questions should be settled first, since they can prevent the zoning permit entirely.
How Wisconsin contractor licensing works
Wisconsin certifies dwelling contractors and licenses electricians and plumbers at state level (see Wisconsin rules). Grant County licenses no trades; state credentials govern and the town verifies them.
Commercial permits
Commercial development under the comprehensive zoning ordinance may require a conditional use permit, heard at public hearing by the county committee. Building code plan review routes to the state or a delegated municipality; the county holds no commercial plan review delegation.

Call 1-855-478-4290 →Mechanical work, and where the state reviews directly
Commercial plans above set sizes go to the state for review first (see Wisconsin rules). In the A-1 agricultural district, permanent non-residence structures carry their own siting requirements, and conversions out of farmland preservation are tracked at state level.
Grant County permit costs and fees
County fees follow the department's published schedule and accompany the zoning permit application, which must be signed and dated on the front page.
| Item | Fee or rule |
|---|---|
| Zoning permit | Per the department schedule, submitted with the completed application |
| Sanitary permit | Through the department's sanitary permit process |
| Shoreland or floodplain application | Where the parcel falls in either zone |
| Town building permit | Set by the town where required |
Vertical distance does not matter for shoreland. Shoreland zoning applies to all land within 300 feet of a navigable waterway, measured from the ordinary high water mark — and the county notes expressly that vertical distance has no implication for whether a parcel is in or out of the shoreland zone.
Trade permits and who may pull them
Trades are state-credentialed and permitted at town level; the county handles zoning, sanitary and conservation.

Review, corrections and what actually causes delay
Grant County's decisive questions are asked before any drawing matters: does the parcel have legal access of sufficient width, and is it inside the shoreland belt. Both are answered by the department, and both can stop a project outright.
