HOA prevalence & preemption
North Carolina has no statute that voids HOA bans on ADUs. The North Carolina Planned Community Act (G.S. Chapter 47F) governs planned communities created on or after January 1, 1999 and the NC Condominium Act (Chapter 47C) governs condominiums; neither contains an ADU carve-out. Restrictive covenants in declarations and bylaws — including those prohibiting accessory structures, secondary kitchens, or short-term rentals — remain enforceable per their terms. SB 495 / HB 627 (pending) is silent on HOA preemption; even if enacted as currently drafted it would preempt local-government zoning but not private restrictive covenants.

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.
