What are the size limits on an ADU in Nevada?
Nevada permits ADUs up to approximately 900 square feet per AB 213 (2023). Individual municipalities may set lower caps; verify with your city or county planning department before ordering.
Do I need a permit for an ADU in Nevada?

Does Nevada require owner-occupancy on the primary residence when I have an ADU?
No — Nevada does not require owner-occupancy under state statute per AB 213 (2023). Local ordinances may still add owner-occupancy requirements in specific cities.
What zoning districts allow ADUs in Nevada?
Most Nevada municipalities permit ADUs in single-family residential zones (R-1, R-2 equivalent). Nevada AB 213 (2023) required cities over 100,000 population to permit at least one ADU pathway by right. Las Vegas and Reno lead adoption. Consult your city zoning code for the specific district table.
How long does an ADU permit take in Nevada?
Typical ADU permit timelines in Nevada run 45-110 days from application to approval. Fast-permitting counties can move in under 30 days; metro-core jurisdictions with discretionary review can extend to 150+ days.
Are there setback requirements for an ADU in Nevada?
Yes — most Nevada municipalities apply the same setback requirements to ADUs that apply to the primary structure (typically 5-10 feet rear and side, 15-25 feet front). Some cities apply reduced setbacks specifically for detached ADUs. Verify with your city zoning code.
Can I finance an ADU purchase in Nevada?
