Do you need a building permit in Bullitt County, Kentucky?
Yes. Bullitt County requires a building permit for new construction and remodeling that includes structural changes, and Buildings & Safety also issues electrical and heating-cooling permits1. Kentucky has adopted statewide building and residential codes, while the statewide residential rule leaves single-family permits, inspections, and certificates of occupancy to local ordinance1011. Bullitt County's published permit practice therefore controls locally: Buildings & Safety reviews plans submitted by contractors, architects, or owners and performs field inspections for code compliance5. We could not confirm a general owner-builder exemption or Bullitt County's complete certificate-of-occupancy rules; ask Buildings & Safety what applies before starting work5.
Who is the Bullitt County building department, and how do you reach them?
Bullitt County Buildings & Safety, at 149 N. Walnut Street, 3rd Floor in Shepherdsville, issues building, electrical, and heating-cooling permits for new construction and structural remodeling5. Reach the division at 502-921-2970, Monday through Friday, 8:00 a.m. to 4:00 p.m.5. Buildings & Safety reviews plans and conducts field inspections, while Planning and Zoning handles zoning compliance, site plans, subdivision plats, rezoning, variances, and conditional-use applications512. Bullitt County's published information identifies those application categories but does not provide a complete submission sequence or building-permit fee schedule12. Ask the appropriate office for the current forms, required plan set, fees, and inspection schedule before filing.
Does Bullitt County have zoning?
Yes. Bullitt County Planning and Zoning administers zoning and floodplain determinations for the unincorporated county and investigates alleged zoning violations2. The office also handles zoning compliance, sign permits, site plans, subdivision plats, rezoning, variances, conditional uses, and most address assignments13. Bullitt County reviews subdivision plats for new development and processes subdivision-review applications14. Kentucky generally requires planning-commission approval before a subdivision plat may be recorded, but a qualifying division for agricultural use that creates no new street is not treated as a subdivision; ordinary agricultural or horticultural production generally requires at least 5 contiguous acres for that definition157. We could not confirm countywide numeric rules for minimum home size, lot size, setbacks, lot coverage, or building height, so request the parcel's zoning classification and dimensional standards from Planning and Zoning before designing13.
How do septic permits work in Bullitt County?
The Bullitt County Health Department performs septic site evaluations, issues permits, conducts inspections, and investigates complaints3. Reach Environmental Services at 502-955-7867 or [email protected], at 181 Lees Valley Road in Shepherdsville16. Obtain the construction permit before installing or altering any part of an onsite system; the permit follows a site evaluation and is valid for 1 year unless the state Cabinet grants an extension9. After installation, the installer must call for inspection, and the system must be inspected before backfilling417. An inspection of an established sewage system costs $75 and includes checking the tank, lateral field, and leakage; a leaking system will not be approved4. Only about 9.1% of Bullitt County soils are rated free of severe limitations for a conventional drain field, so complete the site evaluation before committing to a house location or system budget18.
Can you live in an RV or tiny home on your land in Bullitt County?
Kentucky law does not give you a general right to live in an RV on private land: it only protects sleeping temporarily in a vehicle parked lawfully on a public road, street, or parking lot for less than 12 hours, which is about roadside rest, not full-time occupancy6. Bullitt County's published materials don't set out a separate rule for RV or tiny-home occupancy on private rural land, so confirm any specific plan with Planning and Zoning, which handles zoning classifications and compliance for the unincorporated county13. Because Bullitt County requires a building permit for new construction and structural remodeling, a site-built tiny home large enough to serve as a dwelling will likely need the same building permit and Kentucky Building Code review as any other home1.
Building a home in Bullitt County: what are the steps, in order?
- Ask Planning and Zoning for the parcel's zoning classification, zoning-compliance requirements, and floodplain determination13.
- If dividing the tract, submit the site plan or subdivision plat for county review; qualifying agricultural divisions without a new street may fall outside the statutory subdivision definition147.
- Complete the Health Department's septic site evaluation and obtain the septic construction permit before system work begins39.
- For land in an identified floodplain, obtain both the state and local floodplain permits and design to the applicable floodplain construction criteria819.
- Submit plans to Buildings & Safety for code review and ask for the current fees and inspection sequence512.
- If connecting to a state highway, apply in writing to the Department of Highways District Engineer before constructing a farm or single-family driveway approach20.
What should you check before you buy land in Bullitt County?
Ask the Health Department for a septic site evaluation before you make an offer: only about 9.1% of Bullitt County's soils are rated free of severe limits for a conventional drain field, so many parcels will need an engineered or alternative system18. Check with Planning and Zoning on the parcel's zoning classification and whether it falls in a mapped floodplain, since floodplain development needs both a state and a local permit813. Confirm the parcel's road access and, if it connects to a state highway, whether an approach permit is already on file20. If you're counting on a private well, remember the driller needs a Kentucky-certified water well driller credential to do the work, though this doesn't require a separate homeowner construction permit for an ordinary well21. Bullitt County's median property tax bill runs about $1,994 a year at an effective rate near 0.9%2223.
Watch-outs
- Kentucky's statewide default lets a single-family home skip a building permit, inspection, and certificate of occupancy, but Bullitt County's fiscal court has adopted a local ordinance requiring one, so don't assume the state's no-permit rule applies here111.
- Since August 1, 2008, any construction-related land disturbance of more than one acre, or on a lot of any size that's part of a common development plan, needs its own stormwater permit from Buildings & Safety5.
- Whether Bullitt County recognizes an owner-builder exemption from its building-permit requirement is not established on the county's published pages; confirm your specific project with Buildings & Safety before relying on one5.
- Development in a mapped Kentucky floodplain needs both a state permit from the Division of Water and a local permit, so check with Planning and Zoning before you build near a creek or floodway813.
