Sauk County's Land Resources and Environment Department has taken land use and sanitary permitting fully online, and its Zoning Services Division handles permitting, inspections and enforcement for the county's zoning, shoreland protection, floodplain, rural identification, non-metallic mining reclamation and private wastewater ordinances.
The department's Planning Division provides long-range, recreational, agricultural and preservation planning for the county's rural and urban communities, while Zoning Services delivers technical assistance to the public, town officials and county board supervisors.
This guide covers unincorporated Sauk County. Baraboo, Reedsburg, Wisconsin Dells, Lake Delton, Prairie du Sac and Sauk City permit their own construction; town building inspectors issue building permits in the towns.
Three overlays the application asks about by name. Sauk County's permit guidance directs applicants to note whether the property lies in the floodplain, wetland, shoreland, extraterritorial or sanitary district, and whether it is in the Lower Wisconsin Riverway or the Farmland Preservation Program — each of which can change what is permitted before ordinary zoning is even considered.

- Shoreland protection and floodplain approvals
- Rural identification system numbers
- Non-metallic mining reclamation permits

What is actually local, and what is not
Building standards are statewide. Sauk County's Chapter 7 zoning code carries an unusually detailed use structure — agricultural, community, education, food business, home business, industrial, recreational, residential, resource, retail, storage and waste use categories, each with secondary standards — plus density policy and density credit exchange provisions.
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 land use permit and, on a private system, the sanitary permit — both submitted through the online portal — and then the town building permit under the Uniform Dwelling Code with state Dwelling Contractor credentials. Applications require complete setback distances and a signed, dated form.
How Wisconsin contractor licensing works
Wisconsin certifies dwelling contractors and licenses electricians and plumbers at state level (see Wisconsin rules). Sauk County licenses no trades; state credentials govern, and the county publishes reference lists of plumbers, soil testers and septic maintainers.
Rather talk it over?
Call 1-855-478-4290 →Commercial permits
Commercial development under the county's Chapter 7 zoning code falls into defined land use categories with their own secondary standards, and density provisions may apply. Building code plan review routes to the state or a delegated municipality; the county holds no commercial plan review delegation.
Mechanical work, and where the state reviews directly
Commercial plans above set sizes go to the state for review first (see Wisconsin rules). The county has amended its Chapter 7 zoning code in response to changes in state law and requests from towns, so verify current standards rather than relying on an older copy.
Sauk County permit costs and fees
Fees follow the Land Resources and Environment fee schedule and are paid through the online portal alongside the application.
| Item | Fee or rule |
|---|---|
| Land use permit | Per the department fee schedule, submitted online |
| Sanitary permit | Also online, through the same portal |
| Non-metallic mining reclamation | Under the county's reclamation ordinance |
| Town building permit | Set by the town |
Call before you dig, develop or build. The county states that several uses may require a land use permit and suggests contacting the office prior to any construction, development or excavation — the permit list published online is described as a sampling, not an exhaustive account.
