ADU details

ADU legality: unclear

Stateunclear (Kentucky Revised Statutes Chapter 100 (Planning and Zoning) and the Kentucky Building Code / Kentucky Residential Code) — Kentucky has no statewide ADU preemption. KRS 100 delegates planning and zoning to local cities, counties, and joint planning units. Kentucky Residential Code (KBC IRC 2018 with state amendments) Appendix Q is the floor for tiny / small dwellings. HB 576 (2025) would have legalized by-right ADUs in residential zones but stalled in committee, leaving Clinton entirely under local rule.
Countyunclear (Hickman County (no county-wide planning unit)) — Hickman County is one of the smaller western-Kentucky counties (pop. roughly 4,500) and does not maintain a stand-alone planning-and-zoning office; land-use issues are handled through the County Judge/Executive (Kenny Wilson, +1-270-653-4369) and the Purchase Area Development District. Outside Clinton city limits, residential construction in unincorporated Hickman County is generally governed only by the Kentucky Residential Code via the state Department of Housing, Buildings and Construction; there is no county zoning ordinance addressing ADUs specifically.
Cityunclear (City of Clinton, KY (home-rule class) - no published ADU ordinance) — Clinton (pop. ~1,300) is the Hickman County seat and a home-rule class city. The city's published materials (mayor's office, forms page) do not contain an ADU-specific ordinance, a zoning map, or a separate building permit form - construction permits are handled by walk-in intake at City Hall (112 S. Jefferson St.). Any second dwelling on a single residential lot is therefore evaluated as an accessory structure plus a Kentucky Residential Code dwelling permit issued by the state DHBC, not as a defined ADU.

Practical posture: Clinton has no ADU statute and no county zoning. A Clinton homeowner who wants a second dwelling files a Kentucky Residential Code permit through the state DHBC field office, plus a city utility-tap and occupational-license touchpoint at Clinton City Hall. Expect case-by-case review; outcomes depend on lot size, septic/sewer capacity (Clinton sewer or county health department septic), and informal council approval rather than codified ADU criteria.

Permitting process

Typical duration62 days
Backlog14 days
  1. Confirm parcel and locate floodplain (~5d)
    Pull deed and PVA card from Hickman County PVA (Amanda Ballantine, +1-270-653-5521). Mississippi River bluff terrain - check FEMA Zone X / Zone A maps for the parcel; Clinton sits inland of the river but Bayou de Chien crosses town and triggers flood-zone construction rules on adjacent lots.
  2. Visit Clinton City Hall - utility tap and zoning sanity check (~3d)
    Walk-in to 112 S. Jefferson St. (Mon-Fri 7:30-16:30). Clinton has no zoning code, so the city clerk confirms address, water/sewer service availability, and any neighborhood deed-restriction issues the council is aware of.
  3. Apply for KRC residential permit through Kentucky DHBC (~7d)
    File the Kentucky Department of Housing, Buildings and Construction one- and two-family residential permit (state-issued). Submit floor plan, elevations, foundation detail, energy compliance form (REScheck or KRC Ch. 11 prescriptive). DHBC West KY field office handles intake by mail or email.
  4. Septic or sewer review (~21d)
    If on Clinton sewer, request a tap permit at City Hall. If on septic, file an on-site sewage system application with the Hickman County Health Department; site evaluation required before slab pour.
  5. DHBC plan review (~21d)
    State plan reviewer issues approval or comment letter. Plan-review backlog 2-4 weeks at the Frankfort office; faster for small / Appendix Q dwellings.
  6. Construction inspections
    DHBC field inspector handles foundation, framing, MEP rough, insulation, final. Hickman County is in DHBC Region 1.
  7. Final / certificate of occupancy (~5d)
    Final inspection by DHBC; Clinton City Clerk issues a 911-address verification letter for utility hookup and rental registration where applicable.

Viability (permitted uses)

  • Long-term rental: yes (City of Clinton occupational license requirement for rental income) Long-term rental permitted; rental income subject to Clinton occupational license tax.
  • Short-term rental: unclear (No Clinton STR ordinance on record) Clinton has no STR registration ordinance; Airbnb-style rental falls under occupational-license / sales-tax registration with the city clerk and Kentucky Department of Revenue.
  • Office rental: unclear No defined home-occupation framework; city clerk and council review case-by-case.
  • Home office: yes Home-based business common; occupational license required.
  • Studio / workshop: yes Personal use is unrestricted.
  • Agriculture: yes Backyard chickens / small gardening common in Clinton; no city ban.

Kentucky state — ADU law and programs

State financing programs

Kentucky does not operate an ADU-specific statewide loan, grant, or forgivable-loan program. The Kentucky Housing Corporation (KHC) is the state housing finance agency and administers first-time-homebuyer mortgage products, the Welcome Home Grant (down-payment assistance), the KHC Down Payment Assistance Program (up to $12,500 second mortgage), and Mortgage Credit Certificates. None target ADU construction directly. ADU costs may be financed through standard renovation or construction-loan products under KHC programs when the ADU is part of a qualifying primary-residence transaction.

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.
