Wyandotte County, KS Building Setbacks & Zoning: Setback Rules (2026)

The R-1 single-family district accommodates the bulk of single-family detached housing in the city, and Sec. 27-454(d) ties its setbacks to a 65-foot minimum lot width and a 7,150-square-foot minimum lot area per dwelling unit, plus an 864-square-foot minimum habitable floor area. Setback minimums are not uniform across the zoning code. The A-G agriculture and R rural residential districts require far deeper yards, 50 feet on the front, side-corner and rear lines and 20 feet on an interior side yard, reflecting their larger minimum lot sizes.

The older-neighborhood R-1(B) infill district loosens the standard: still 25 feet in front, but only 10 percent of the lot's width (minimum 3 feet) on an interior side yard and 25 feet rear. The R-2 two-family district requires an 8-foot interior side yard and 30-foot rear yard on a 75-foot-wide lot. Homes built on legally narrow lots along the eastern part of the city follow the separately incorporated Narrow Lot Design Guidelines referenced in Sec. 27-454(d)(3)b instead of the standard lot-width rule. Before construction begins, the property owner needs a building permit under Sec.

27-363 and a certificate of occupancy under Sec. 27-364, both administered by the building official who enforces the zoning article under Sec. 27-362; additional parking and design standards cross-reference division 8 and division 9 of the same article.
