Las Vegas, NV Building Setbacks & Zoning: Lot Coverage Limits (2026)

LVMC 19.06.070's Table 1 - Building Placement sets the maximum lot coverage for the R-1 Single Family Residential District at 50 percent, applied against the minimum 6,500-square-foot lot required in the district. Lot coverage measures the ground-floor footprint of all buildings on the lot, main dwelling and accessory structures together, against the total lot area, so a builder on a minimum-size R-1 lot has roughly 3,250 square feet of coverage to work with across the house, garage, casita and any sheds.

Accessory structures carry an additional, more specific coverage limit under Table 2. The size and coverage standard caps a detached accessory structure at no more than 50 percent of the floor area of the principal dwelling unit, and a companion footnote layers on a site-wide limit: the aggregate ground-floor area of all accessory buildings on the lot cannot cover more than 50 percent of the rear yard area. A Residential Accessory Dwelling Unit is subject to the same 50-percent-of-principal-dwelling cap.

LVMC 19.06.030 reinforces the coverage rule at the lot level: no lot can be reduced through further subdivision or conveyance if doing so would push its size, width, setbacks, yards, required open space or total lot area below what this Chapter requires, and unit density cannot be increased except in conformity with the Chapter's standards. Together, the two coverage figures mean a homeowner adding a shed, detached garage or ADU has to check both the overall 50 percent lot-coverage ceiling and the separate accessory-structure and rear-yard caps before applying for a building permit.
