Summary
The county treats a fence as excluded from its "Structure" definition, so no county zoning permit is required for an ordinary fence in unincorporated towns. Fences within 75 feet of a lake or river are regulated under the Shoreland Ordinance. Cities and villages may require their own permit.
The term "structure" does not include flag poles, mailboxes, fences (unless located within 75 ft. of the ordinary high water mark of a navigable waterway)...
Full Breakdown
Because the Basic Zoning Ordinance excludes fences from "Structure," a standard fence in a consenting unincorporated town does not trigger a county zoning permit. However, the separate Waukesha County Shoreland & Floodland Protection Ordinance folds a fence back into "Structure" when it stands within 75 feet of the ordinary high water mark of a navigable waterway, which can require a shoreland zoning permit. Inside cities and villages such as Waukesha, Brookfield or Menomonee Falls, a municipal fence permit is often required. Always confirm with the Planner of the Day at (262) 896-8300 before building near water or a property line.
Violations & Fines
Building a regulated shoreland fence without the required permit can trigger a stop-work order, permit-after-the-fact fees, and zoning forfeitures.
