ADU Rules: Las Vegas vs Paradise

Does Las Vegas allow ADUs (casitas) on single-family lots?

Yes, but only with a Special Use Permit under LVMC Title 19. Class I accessory structures with cooking facilities are allowed on lots of at least 6,500 sq ft in the R-E, R-D, R-1, R-PD, R-CL, and R-MH zones.

Can I rent out a Las Vegas casita?

Only if the primary dwelling is owner-occupied. Title 19 prohibits rental of a Class I accessory structure unless the principal dwelling is owner-occupied, and short-term rentals are separately regulated under LVMC Title 6.

Is Las Vegas covered by California-style ADU streamlining?

No. Nevada has no statewide ADU mandate, so the city retains discretionary review through the Special Use Permit process. Las Vegas is not required to provide ministerial approval the way California cities are.

Are ADUs allowed in unincorporated Clark County?

Yes. Title 30 permits Accessory Apartments in the R-U, R-A, R-E, R-D, R-1, R-T, R-2, H-2, and H-1 zones. Recent amendments have removed the minimum lot size and one-bedroom cap, and basement ADUs are now explicitly allowed.

How big can an unincorporated Clark County ADU be?

Up to 1,200 sq ft for detached units, or 50% of the primary dwelling's floor area for attached units, under Title 30. Setbacks and lot coverage rules of the underlying zone still apply.

Is there a state ADU mandate in Nevada?

No. Nevada has no statewide ADU law equivalent to California's Gov Code §65852.2, so Clark County retains discretion on parking, owner-occupancy, and rental restrictions in Title 30.
