Clark County caps lot coverage under Title 30 UDC. R-1 zones typically allow 50 percent building coverage. Impervious surface limits apply in FEMA flood zones and sensitive watershed areas.
Clark County Title 30 UDC restricts how much of a residential lot may be covered by buildings. Standard R-1 zoning typically limits total building coverage (primary plus accessory structures) to about 50 percent of the lot area, though specific figures vary by district and lot size. Larger lots in R-E (Rural Estates) and R-D (Desert Rural) zones have lower coverage percentages, often 20 to 30 percent, to preserve the low-density rural character. Master-planned communities like Summerlin South, Mountains Edge, and Inspirada set their own coverage limits through Specific Plans, often aligning with HOA design guidelines. Because of Las Vegas Valley flash flood risk, some parcels in designated FEMA Special Flood Hazard Areas have additional impervious surface caps that include pools, decks, patios, and driveways, measured under Clark County Regional Flood Control District rules. Accessory dwelling units added under Nevada AB 372 must still comply with lot coverage and setback standards. Pool decks and sheds count toward coverage calculations.
Exceeding lot coverage results in permit denial or stop-work orders. Structures built above permitted coverage must be removed or reduced. Flood control violations can trigger separate drainage-district enforcement and FEMA mapping consequences.
