State ADU details

State insurance regimes

North Carolina runs two parallel residual property-insurance markets: the FAIR Plan (administered by the North Carolina Joint Underwriting Association, NCJUA) covers fire-and-extended-coverage perils for non-coastal properties, and the Coastal Property Insurance Pool (formerly the Beach Plan, administered by the North Carolina Insurance Underwriting Association, NCIUA) covers windstorm and hail in the 18 designated coastal counties east of the Intracoastal Waterway. Both are statutorily authorized under G.S. Chapter 58, Article 45. The Coastal Pool is statutorily defined as the 'market of last resort' for the coast. The NC Department of Insurance (NCDOI) regulates rates and forms; NC's rate-bureau system (the Rate Bureau files rates that NCDOI may approve, deny, or settle) is unique among states and produces the recurring multi-month rate hearings that have drawn national attention.

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.
