How zoning works in Clark County
Zoning and permit authority in Nevada is mostly local. Incorporated cities like Las Vegas run their own zoning codes, planning departments, and building inspectors. The county's planning department typically only handles unincorporated parcels, but counties set the framework for Nevada state law compliance (ADU rules, wildfire hazard zones, flood plain overlays, subdivision requirements). The first question when screening any Clark County parcel is always whether it sits inside city limits — that determines who your permit authority is.
