Nevada ADU Eligibility Checker
Nevada has no statewide ADU mandate. Whether you can build on your Nevada property depends on your city's or county's zoning rules AND — crucially — your HOA's CC&Rs. The majority of Las Vegas-area residential lots sit in planned communities with active HOAs, and those CC&Rs often prohibit accessory dwellings outright.

How Nevada ADU Eligibility Works
Nevada has no state-level ADU mandate. Whether you can build on your Nevada property depends on: (1) your city's zoning code or your unincorporated county's rules; (2) any applicable planned-community or master-planned-community restrictions; and (3) your HOA's CC&Rs, which Nevada courts enforce under NRS 116. Las Vegas and Clark County have historically been more restrictive on ADUs than the major Western cities, though local rules are evolving. Reno and Washoe County are similarly varied. The calculator reads Nevada properties as yellow for most configurations because the correct answer is 'check locally and check your HOA.'
Las Vegas Metro, Reno, and Unincorporated Areas
City of Las Vegas allows ADUs in specific residential zones with a conditional use permit, subject to lot-size, setback, and parking rules. Henderson has a narrower ADU allowance tied to specific districts. North Las Vegas has limited provisions. Unincorporated Clark County's ADU rules vary by residential district and generally require a conditional use permit. Reno updated its zoning code in recent years to allow ADUs in several residential districts subject to standard setback and height rules; the Reno path is generally more permissive than Las Vegas metro. Sparks has similar rules to Reno. Washoe County covers unincorporated areas including Incline Village and portions of Lake Tahoe — Lake Tahoe-area rules layer TRPA (Tahoe Regional Planning Agency) requirements on top of county zoning, making the eligibility picture materially more complex. Carson City, as a consolidated city-county, has its own rules.
The Nevada HOA Reality
This is the single most important eligibility factor for Nevada ADUs. An overwhelming share of post-1990 Las Vegas-area residential lots sit in planned communities with active HOAs, and those HOAs' CC&Rs often prohibit accessory dwellings, second residences, rental activity, or all three. Nevada HOAs derive enforcement authority from NRS 116 (Common-Interest Ownership Act), and Nevada courts have consistently upheld CC&R restrictions on ADUs. There is no state-level preemption analogous to California's or Washington's. Practically, this means: Summerlin, Anthem, Mountains Edge, Southern Highlands, Inspirada, Green Valley, Seven Hills, and most other named planned communities have CC&Rs that you need to check before assuming an ADU is possible. Many homeowners start ADU projects and discover only during design review that the HOA's CC&Rs block the path. Read your CC&Rs before any architect engagement.
