Clark County's rural residential districts (R-20, R-10, R-5) set no numeric maximum lot coverage in Table 40.210.020-3 (listed as N/A). Coverage is effectively controlled by large minimum lot sizes and the required setbacks. Urban zones have their own coverage limits.
In Table 40.210.020-3 of Clark County Code 40.210.020, the Maximum Lot Coverage column for the rural R-20, R-10, and R-5 districts is listed as N/A, meaning the rural districts rely on very large minimum lot areas (20, 10, and 5 acres respectively) and the 50/25/20-foot setbacks rather than a percentage cap. Urban low-density residential zones in CCC Chapter 40.220 and cluster-development standards (Table 40.210.020-5) do apply specific coverage and dimensional limits. Impervious-surface and stormwater standards under CCC Chapter 40.386 can further constrain how much of a lot may be developed.
Where a coverage or impervious-surface limit applies, exceeding it can block permit approval and require redesign or stormwater mitigation.
