Summary
Unincorporated Jackson County caps how much of a lot can be covered by buildings under UDC Sec. 120 and Table 2-2. The limit tracks zoning district: 35 percent in the R-1 single-family district, 40 percent in R-2 and R-3, and as high as 75 percent in the LI and GI industrial districts. Public Development reviews coverage at permitting; exceeding the cap is a UDC violation.

Full Breakdown
UDC Sec. 120 states that no lot may be developed to exceed the maximum building coverage specified for its zoning district under Article 2 of the Unified Development Code, unless another UDC provision specifically allows more. Table 2-2, Dimensional Requirements for Zoning Districts, sets the actual percentages for each of the 15 zoning districts. Building coverage, which includes both principal and accessory buildings and structures, is capped at 20 percent in the PCFD Planned Commercial Farm District; 25 percent in A-1, A-2, A-3, AR, and MH; 35 percent in R-1, the county's low-density single-family district; 40 percent in R-2, R-3, and CRC; 50 percent in NRC; 60 percent in HRC; and 75 percent in LI and GI, the light and general industrial districts, with HI capped at 40 percent.
The table separately sets a minimum landscaped open-space requirement for multi-family and nonresidential development, ranging from 20 percent in R-3, MH, NRC, and CRC down to 10 percent in LI and GI. Coverage is measured at the time of building permit review by the Public Development Department against the standard adopted for the district shown on the official zoning map. Because Sec. 120 folds the numeric limit into whichever standard Table 2-2 assigns to the parcel's district, a lot rezoned to a different district automatically takes on that district's coverage cap the next time it is developed.
Violations & Fines
Developing a lot beyond the building coverage percentage set for its zoning district in Table 2-2 violates UDC Sec. 120. The Public Development Department catches most violations at building permit or site plan review and can withhold approval until the plan is revised to meet the cap; a structure built over the limit is a nonconforming building or structure under UDC Sec. 131 and cannot be expanded further without meeting the district's coverage cap.
