Nevada

Nevada's rapid population growth — particularly in the Las Vegas and Reno metros — has created strong demand for new housing. Accessory dwelling units offer homeowners a way to add supply on existing lots. ADU Pass helps Nevada property owners handle the permit paperwork.

State ADU details

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.

State insurance regimes

Nevada does NOT operate a FAIR Plan or any state residual property-insurance market as of 2026-04-26 — and uniquely, Nevada in 2025 enacted Assembly Bill 376 (AB 376, effective 2026-01-01) authorizing insurers to exclude wildfire losses from standard homeowners policies and offer wildfire-only coverage as separate stand-alone policies, plus a four-year regulatory sandbox for new product structures administered by the Nevada Division of Insurance. Critically, AB 376 has NO residual-market backstop — Nevada created no FAIR plan, wildfire pool, or insurer of last resort. Wildfire-related cancellations and non-renewals had grown 82% in the year prior; AB 376 is widely seen as accommodating insurer retreat rather than solving the underlying capacity problem. Nevada has the country's fastest WUI development rate (208% growth 1990-2020); ADUs in Lake Tahoe basin (Incline Village, Crystal Bay, Glenbrook, Zephyr Cove), Carson City foothills, Reno-Sparks west side, and rural Nevada / Elko WUI areas inherit that risk profile. Property insurance for owner-occupied dwellings is regulated by the Nevada Division of Insurance under NRS Title 57.

Known state issues (2)

  • policy-review (since 2025-06) — ADU economics in WUI Nevada (Lake Tahoe basin, Reno-Sparks west, Carson foothills, rural Nevada) will increasingly require a separate wildfire-only policy on top of the standard HO. Premiums for that combined coverage are not yet stable; some lenders may require wildfire endorsement as a condition of mortgage. Construction lenders and refinance underwriting affected. (source)
  • legislative-session (since 2025-06) — ADU permittability remains a local-only matter. Big-metro reforms (Reno October 2025 ordinance) drive most current ADU permit volume. (source)
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.
