Clark County allows accessory dwelling units on residential properties, and Nevada Assembly Bill 396 recently expanded homeowner rights to build casitas statewide. Specific regulations vary by zoning district, including setback requirements, maximum square footage, parking, and owner-occupancy rules. ADU permit fees in Clark County typically range from $200 to $800 for plan check and $500 to $2,500 for the building permit, with construction costs averaging $150 to $300 per square foot. The ROAD Act’s pre-approved design provisions could further simplify the permitting process. (FOX5 Vegas)
