Waukesha, WI Building Setbacks & Zoning: Setback Rules (2026)

Section 22.24's Setback and Yards subsection lays out the minimum distances a principal building must sit from property lines in Waukesha's base single-family district, RS-1, which allows up to 2.2 dwelling units per net acre. A home needs at least thirty-five feet between it and any street right-of-way, at least fifteen feet on each side yard, and at least fifty feet from the rear lot line. Where a lot borders a navigable lake, pond, stream, or flowage, an additional shoreyard setback of seventy-five feet from the ordinary high-water mark applies on top of the standard yards, tying into the separate Shoreland Regulations in Section 22.22.

These figures are specific to RS-1; Waukesha's other zoning districts, including RS-2 through RS-4, the RD and RM residential districts, and the various business and manufacturing districts, each carry their own Setback and Yards subsection in Chapter 22 with different street, side, and rear yard numbers suited to that district's density and use. As with lot area, height, and lot coverage, Section 22.24 allows these setback minimums to be reduced or increased only if the property is part of a Planned Unit Development Overlay District approved under Section 22.52; outside a PUD, a builder who needs relief from a setback must apply to the Board of Zoning Appeals for a variance under Section 22.68, which requires showing an exceptional or extraordinary condition tied to the specific property.
