Jefferson County, WI Environmental Rules: Boat Dock Permits (2026)

The W Waterfront District exists to identify residential and commercial areas along the county's waterways (Sec. 22-408). Principal uses there are narrow: an existing single-family dwelling in the floodway, parks and conservancy areas, and non-structural open space or recreation (Sec. 22-409). Sec. 22-410 then lists accessory uses, and it is the only place docks and piers appear: boathouses if they meet the referenced structural standards, and boat docks and piers for private residential usage only. No accessory structure listed in this section, including a boat dock, may be used for human occupancy, and any unit placed during flood-stage periods must be removed from designated hazard areas.

Commercial water-related activity is handled separately and requires more than a zoning permit: marinas, boat and bait shops, taverns and restaurants tied to the water, boathouses on vacant lots, and public or commercial access ramps to navigable waters are conditional uses under Sec. 22-411, meaning an application to the planning and zoning department, review by the planning and zoning committee, a published Class 2 notice, and certified-mail notice to affected towns and nearby property owners at least ten days before a public hearing (Sec. 22-581).

Because this is a Chapter 22 zoning provision, it only reaches the unincorporated towns that have adopted Jefferson County zoning under Wis. Stat. 69; towns that run their own zoning are not covered. The Planning and Development Department issues the zoning permits and reviews conditional use applications.
