Summary
The joint Wichita-Sedgwick County Unified Zoning Code sets no blanket lot-coverage percentage for base districts like RR or SF-20. The one hard cap in the whole Code applies to Nonresidential Community Unit Plan (CUP) developments: buildings cannot cover more than 30 percent of the CUP site, in the city or the unincorporated county.
b.Nonresidential CUPs. The following nonresidential CUP regulations shall apply to development or construction on Sites with a Contiguous area of six acres or more that are held under unified control at the time of initial approval and that are now or hereafter zoned either LC or GC, or a combination thereof... (b)Maximum Lot coverage. Buildings shall not cover more than 30 percent of the land upon which the Development is proposed.

Full Breakdown
The Wichita-Sedgwick County Unified Zoning Code's base zoning districts (RR, SF-20, SF-10 and the rest) control building bulk through minimum lot area, lot width and setback numbers rather than a stated maximum-coverage percentage, so a lot-coverage search across the whole Code returns only one number: Sec. b(2)(b), inside the Community Unit Plan ("CUP") Overlay District. That rule governs nonresidential CUP developments on sites of six contiguous acres or more held under unified control and zoned LC or GC (or, at the owner's option, on smaller LC/GC sites or on land zoned NO, GO, NR, CBD, OW, IP, LI, GI or U).
Buildings on that CUP site cannot cover more than 30 percent of the land area. The same CUP section requires a 35-foot setback from all street rights-of-way or from a Contiguous residential district line, and a 30-foot rear yard, alley or service drive. Where the Development abuts a residential district, a six-to-eight-foot solid screening wall of brick, stone or masonry is also required (reduced to three feet within the setback area). The CUP District applies wherever it is mapped, in the City of Wichita or in unincorporated Sedgwick County, since the Purpose clause carries no city-only or county-only limitation (unlike, for example, the RR District, which the Code expressly reserves to unincorporated Sedgwick County).
The Planning Commission or Governing Body can waive or modify the 30 percent cap as part of approving or amending a CUP under Sec. d. Separately, under the Zoning Adjustments procedure at Sec. V-I, the Planning Director may administratively approve an increase in maximum lot coverage of up to ten percent without a full CUP amendment, provided the applicant shows the request meets the review criteria.
Violations & Fines
Building beyond the 30 percent CUP coverage cap without an approved waiver or Zoning Adjustment is a Code violation under UZC Article VIII. In the unincorporated county it is a class H violation prosecuted under Chapter 8 of the Sedgwick County Code, capped at a $500 fine, with each day of the violation a separate offense; the same conduct inside Wichita is a misdemeanor punishable by up to $500 and six months in jail. The City or County can also withhold permits, revoke an issued permit, stop work, or seek an injunction to force compliance.
