HOA prevalence & preemption
Oklahoma has no statewide statute that voids HOA bans on ADUs. Common-interest communities in Oklahoma are governed primarily by the Oklahoma Real Estate Development Act (60 O.S. §§851-858) for HOAs and by the Unit Ownership Estate Act (60 O.S. §§501-530) for condominiums. Restrictive covenants in declarations and bylaws — including those prohibiting accessory structures or secondary kitchens — remain enforceable per their terms.

Oklahoma County — county ADU rules and overlays
County ADU ordinance
Oklahoma County (state-capital county; ~798,000 residents — Oklahoma's most populous county; encompassing Oklahoma City partial — most of OKC is in Oklahoma County, with portions in Cleveland, Canadian, and Pottawatomie counties — plus Edmond, Bethany, Warr Acres, Nichols Hills, The Village, Spencer, Forest Park, Lake Aluma, Choctaw, Harrah, Jones, Luther, Midwest City, Del City, Nicoma Park, Arcadia, and unincorporated tracts) regulates land use in unincorporated areas through the Oklahoma County Zoning Regulations, administered by the Oklahoma County Planning Commission. Oklahoma is generally a Dillon's Rule state with broad municipal home-rule for charter cities under Oklahoma Const. Art. 18; counties have limited zoning authority over unincorporated areas under 19 OS § 866.1 et seq. Oklahoma has no statewide ADU preemption — Oklahoma's stateAduLaw is netEffect 'no-statewide-law'. The Oklahoma County zoning regulations permit 'accessory residential structures' / 'guest houses' in agricultural and large-lot residential districts (AR, R-1, R-2) by right on parcels of typically 1+ acres subject to size limits and parking; smaller residential districts treat ADUs as conditional uses requiring Board of Adjustment approval.

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.
