Montgomery County — county ADU rules and overlays

County ADU ordinance

Montgomery County (the state-capital county; ~225,000 residents; encompasses the City of Montgomery, AL state government complex, Maxwell-Gunter Air Force Base, and rural unincorporated tracts north and east toward Wetumpka) regulates land use in unincorporated areas through the Montgomery County Subdivision Regulations and zoning is administered jointly with the City of Montgomery via the Montgomery City-County Planning Commission (Code of Alabama Title 11, Chapter 52). Alabama is a Dillon's Rule state with no statewide ADU preemption — Alabama's stateAduLaw is netEffect 'no-statewide-law' — so accessory dwelling units in unincorporated Montgomery County fall under whatever the Planning Commission's joint zoning resolution permits in each district. Historically the county has not maintained an ADU-specific ordinance distinct from the city's; accessory dwellings on unincorporated parcels are typically processed as 'guest houses' or 'accessory residential structures' under the same rural / agricultural zoning categories that allow farm-help housing and accessory living quarters by right on parcels of 1+ acres.

Alabama state — ADU law and programs

State financing programs

Alabama operates no ADU-specific statewide loan, grant, or forgivable-loan program. The Alabama Housing Finance Authority (AHFA) is the state's housing finance agency and administers first-time-homebuyer mortgages, down-payment assistance, mortgage credit certificates, and Low-Income Housing Tax Credit allocation, but none of its programs target ADU construction directly. The Alabama Department of Economic and Community Affairs (ADECA) administers the federal HOME Investment Partnerships Program; HOME funds can in principle support ADU construction by income-qualified households when paired with a participating local jurisdiction, but Alabama has no state-level ADU set-aside.

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.
