Do you need a building permit in McCracken County, Kentucky?
McCracken County, Kentucky requires building permits for buildings outside the City of Paducah, including single-family homes.
McCracken County, Kentucky requires building permits for buildings outside the City of Paducah, including single-family homes1. The county has adopted Kentucky's building and residential codes and runs inspections in that jurisdiction; residential accessory storage buildings require a permit but are excepted from the inspection program1,3. Kentucky otherwise does not require a building permit for a single-family dwelling unless a local ordinance does, and McCracken County has enacted that local framework3,13. Inside Paducah, ask the city for the building permit and zoning approval; septic permits remain with the Purchase District Health Department2,3,4.
Who is the McCracken County building department and how do you reach them?
McCracken County's Inspection Department handles building and electrical permit applications, payments and inspection requests through Cloudpermit.
McCracken County's Inspection Department handles building and electrical permit applications, payments and inspection requests through Cloudpermit14. The county publishes a $25 electrical permit fee before electrical work begins; separate electrical plan-review, inspection, certificate-of-occupancy inspection and reinspection fees can also apply15. Inside Paducah, ask the city about building permits and zoning approval because the county building-code and zoning chapters exclude the city2,3. Purchase District Health Department still handles septic permits and inspections for McCracken County, including addresses inside Paducah4,5.
Does McCracken County have zoning?
McCracken County zoning applies to all land in the county except the City of Paducah, which has separate municipal rules.
McCracken County zoning applies to all land in the county except the City of Paducah, which has separate municipal rules2. The county code publishes Agricultural, Rural Residential, Urbanizing Residential, Mobile Home Park, Commercial, Light Industry and Heavy Industry districts16. In the Agricultural and Rural Residential districts, residential setbacks are 30 feet in front, 8 feet on the side and 25 feet at the rear; accessory-building side and rear setbacks are 4 feet and 8 feet17. Subdividing land requires planning-commission approval before a plat may be recorded, subject to Kentucky's statewide process18. Kentucky excludes a division made for agricultural use from the subdivision definition when no new street is involved, subject to the state claim's conditions19. Ask Planning & Zoning to confirm the parcel's district and allowed use before designing a home, RV setup or accessory building20.
How do septic permits work in McCracken County?
The Purchase District Health Department administers onsite sewage work in McCracken County.
The Purchase District Health Department administers onsite sewage work in McCracken County4. A homeowner installing a system must obtain a permit from the local health department, and local inspectors perform the site evaluation and inspections5. A residential subdivision lot served by a septic tank and field lines must be at least one acre and 75 feet wide at the building setback line; the County Health Officer may require a larger lot or greater width6. The department lists a $250 site-evaluation cost and a $250 permit cost21. Kentucky requires the permit before any part of a system is constructed, installed or altered, and the permit lasts one year unless extended22. Only about 2.8% of county soils are rated without severe limits for a conventional drain field, so make the site evaluation a purchase contingency23.
Can you live in an RV or tiny home on your land in McCracken County?
In McCracken County's zoning jurisdiction outside Paducah, a recreational vehicle community needs conditional-use approval in the Agricultural and Rural Residential districts and is permitted in the Commercial district.
In McCracken County's zoning jurisdiction outside Paducah, a recreational vehicle community needs conditional-use approval in the Agricultural and Rural Residential districts and is permitted in the Commercial district7. The rule covers two or more campers or RVs on one lot and certain lots combining a principal building with rental or lease RV spaces7. RVs in a regulated community must remain transient and cannot become permanent structures, have decks or skirting, lose their wheels or connect permanently to utilities7. A single RV on a private lot is a different question: we could not confirm whether McCracken County allows one to be lived in long-term, so ask Planning & Zoning about the parcel's district and the exact setup20. A tiny house is treated differently: Kentucky's residential code allows a tiny house as a single dwelling unit set on a permanent foundation, but McCracken County zoning, building-permit and septic requirements still apply to it outside Paducah8. Manufactured homes follow Kentucky's separate manufactured-home statutes rather than the standard residential code24.

- Schedule inspections and the applicable trade permits. A homeowner may pull a plumbing permit for a personal residence; a qualifying owner may personally perform HVAC work after obtaining the homeowner HVAC permit, submitting the required affidavit and plans, and meeting the rule's other conditions12,25.
