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

The RR Rural Residential District's Purpose clause states plainly that it "is intended for application in unincorporated Sedgwick County," so its property development standards at Sec. d govern most large-lot residential land outside city limits. Every RR site needs a minimum two-acre lot (larger where sewage lagoons serve the property, per Sec. e) and 200 feet of lot width. From there, the setbacks are numeric and specific: 30 feet minimum front setback, 25 feet minimum rear setback, 20 feet minimum interior side setback, and 20 feet minimum street side setback, all measured for the Principal Structure.

Accessory structures follow a separate, generally reduced setback and height table at Sec. e, and front setbacks on unplatted tracts or along major roadways can be adjusted under Secs. e(2) and (3). A compatibility setback under Secs. 5, triggered when RR-zoned land sits next to a different intensity of use, can override the base numbers and require additional separation. Maximum building height in the RR District is 35 feet, rising to 45 feet if the structure sits at least 25 feet from every lot line; there is no height cap at all for barns, silos and similar farm buildings.

Property owners who need relief from these numbers do not have to seek a formal rezoning: under the Zoning Adjustments procedure at Sec. V-I, the Planning Director, with the concurrence of the Director of the Metropolitan Area Building and Construction Department, can administratively approve reducing any Front, Side or Rear Setback by up to 20 percent, or by up to 50 percent when the yard being adjusted abuts a golf course, open space or reserve, or is 300 square feet or smaller. A formal Variance beyond that administrative cap goes to the Board of Zoning Appeals, which requires a complete application, a nonrefundable fee set by the Governing Body, and a noticed public hearing.
