Clark County — county ADU rules and overlays
County ADU ordinance
Title 30 permits one accessory dwelling unit (commonly referred to as a casita or guest house) on residential parcels in most R-D, R-E, R-1, R-2, and R-T zoning districts subject to size caps, setback compliance, and a minimum parcel size that varies by district. Owner-occupancy of either the primary or accessory unit is required, and short-term rental of the ADU is prohibited outside the county's STR licensing regime.
County regulatory overlays
- airport-noise-zone — An ADU permit inside the overlay typically triggers a one-time avigation easement recordation and may require enhanced glazing. Federal Part 150 noise compatibility rules are administered by the County, not the FAA directly.
- wui-fire-zone — Mt. Charleston Town Advisory Board has additional design-review authority over ADU exterior treatments.
- flood-zone — Clark County is a Class 5 CRS community, providing a 25% NFIP premium discount. The CCRFCD is a separate regional agency but enforces county floodplain ordinance.
- other — ADUs in RRDOD are permitted by right on conforming lots but must conform to the design palette; non-earth-tone exteriors will be denied.
Nevada state — ADU law and programs
State financing programs
Nevada Housing Division (NHD), under the Department of Business and Industry, does not operate an ADU-specific loan or grant product as of 2026-04-26. NHD's primary homeowner-facing program is Home Is Possible, providing first-time and qualifying homebuyers in Clark and Washoe counties up to 4% of the loan amount as a non-repayable grant for down payment and closing costs, paired with a 30-year fixed-rate first mortgage. The Home Is Possible For Heroes overlay serves teachers, military, first responders, and healthcare workers. NHD also issued $283.3 million of 2024 tax-exempt bonding authority for affordable-housing development (multi-family); separately, the Nevada Affordable Housing Assistance Corporation (NAHAC) administers federal Hardest Hit Fund and Homeowner Assistance Fund programs for delinquency relief. None of these is ADU-specific; ADU construction can be financed only as part of a qualifying primary-residence purchase or refinance.
Federal (United States) — ADU-relevant rules and programs
Federal ADU law
The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.
Federal financing programs
Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.
Federal tax credits
There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.
Federal housing programs
HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
