Spring Valley is an unincorporated town, so Clark County, not the City of Las Vegas, governs casitas there under Title 30 of the county code. As of October 2026, the county's changes effective March 5, 2026 removed various lot-size limits for accessory living quarters, with a special use permit still required on lots under 4,000 sq ft.
