Clark County, NV Building Setbacks & Zoning: Setback Rules (2026)

Clark County Title 30 (the Unified Development Code or UDC) establishes setback requirements for all zoning districts in unincorporated areas including Paradise, Spring Valley, Enterprise, Summerlin South, and Sunrise Manor. Standard R-1 (Single-Family Residential) requires a 20-foot front-yard setback measured from the property line to the primary structure, 5-foot side-yard setbacks, and a 15-foot rear-yard setback. R-E (Rural Estates) and R-D (Desert Rural) zones require larger setbacks, typically 30 feet front and 20 feet side for parcels of one or more acres. Corner lots must observe the front-yard setback on both street-facing sides. Flag lots, irregular parcels, and panhandle configurations follow alternative measurement rules in Title 30 Chapter 30.40. Master-planned communities like Summerlin South operate under Specific Plans that supersede base zoning, often imposing tighter setbacks plus CC and R requirements. Encroachments like eaves, bay windows, and mechanical equipment may project into setbacks a limited distance. Variances require hearing before the Board of County Commissioners or Planning Commission. Always verify with the Clark County Department of Comprehensive Planning before construction.
