Project questions
Frequently asked questions for Sauk County
Who handles permitting for this jurisdiction?
Sauk County Land Resources and Environment Department, Zoning Services Division is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 608-355-3245.
How long might review take?
N/A; Chapter 7 requires the Zoning Administrator to notify an owner within 10 working days when a land-use application is incomplete, but it does not publish a standard approval timeline.
How are inspections scheduled?
Contact Zoning Services at 608-355-3245 to arrange or confirm county zoning, shoreland, floodplain or sanitary inspections. A foundation within 10 feet of a required yard or setback, or whose compliance cannot otherwise be confidently determined, requires a registered survey and immediate filing after the footing, slab or foundation is completed. Arrange building and UDC inspections separately with the inspector serving the affected town; the county publishes a current town-inspector contact list.
Which codes and exemptions should I review?
Sauk County administers Chapter 7 zoning where a town has adopted county zoning, Chapter 8 shoreland protection, Chapter 9 floodplain zoning, Chapter 18 rural identification, Chapter 24 nonmetallic-mining reclamation and Chapter 25 private onsite wastewater treatment rules. Incorporated municipalities, extraterritorial areas and locally zoned towns retain their own general zoning authority. A county land-use permit is not a building permit; the affected town issues building permits and administers Wisconsin UDC/building-code requirements. A county land-use permit is not required for an accessory structure of 120 square feet or less or a wind tower under 25 feet when it meets all setbacks and other applicable standards and no other Sauk County ordinance requires approval. Fences and walls over 6 feet high and more than 50% opaque are treated as structures and remain subject to the applicable requirements.
