#116 of 120 in Kentucky

Unincorporated Boone County, Kentucky requires a building permit for a new home and work affecting structure, safety or mechanical systems, with a zoning permit obtained first1. Start construction only after the building permit is issued, and schedule required inspections during construction1. County zoning applies on unincorporated land; incorporated cities have separate zoning ordinances2. Septic permits throughout Boone County, cities included, go through the Northern Kentucky Health Department3.

Do you need a building permit in Boone County, Kentucky?

Unincorporated Boone County requires building permits and inspections for work affecting a home's structure, safety or mechanical systems, including new homes, additions, garages, pools, sheds and residential demolition1. Boone County uses Kentucky residential and building codes10. Fences under 7 feet and certain small detached structures not used as living space are exempt from building permits11. A qualifying farm dwelling and related farm buildings on at least 10 acres outside municipal limits may qualify for a farmstead exemption, subject to agricultural-use and PVA registration conditions6.

Inside Florence and Walton, city building-permit rules apply12,13. Erlanger, mainly in Kenton County but reaching into Boone County, requires a city building permit through its Building and Zoning Administrator14. Septic evaluation, permitting and inspection remain with the Northern Kentucky Health Department throughout Boone County3.

Who is the Boone County building department, and how do you reach them?

The Boone County Building Department is at 2950 Washington Street, 3rd Floor, Burlington, KY 41005, phone 859-334-2218, email bcbd@boonecountyky.org.

The Boone County Building Department is at 2950 Washington Street, 3rd Floor, Burlington, KY 41005, phone 859-334-2218, email bcbd@boonecountyky.org1. For unincorporated Boone County, obtain the Planning Commission's zoning permit before applying online for the building permit; begin work only after issuance and schedule required inspections during construction1. Report plan changes to the department15. We could not confirm general building-permit fees; ask the Building Department for the fee for your project1. Homeowner plumbing and HVAC permit paths require advance applications, supporting documents and personally performed work6,7.

Does Boone County have zoning?

Unincorporated Boone County has county zoning.

Unincorporated Boone County has county zoning2. Florence, Walton and Union have city zoning rules adopting Boone County regulations16,17,18. Erlanger, mainly in Kenton County but reaching into Boone County, maintains its own zoning ordinance19. Septic permits remain with the Northern Kentucky Health Department throughout Boone County3.

The Union Town Plan specifies front yards of 10–50 feet from the right-of-way, side yards of at least 5 feet and rear yards of at least 20 feet for principally permitted structures in UTC, UC and UNO districts—not unincorporated land generally20. Minimum lots in that plan are 4,000 square feet in Union Commercial and 20,000 square feet in Union Neighborhood Office20.

Ask the Boone County Planning Commission to identify the parcel's jurisdiction, district and applicable standards; reach the commission at 2950 Washington St, Burlington, KY 41005, (859) 334-2196 or plancom@boonecountyky.org21. We could not confirm unincorporated Boone County's minimum dwelling size, accessory-dwelling rules or individual manufactured-home placement rules; ask the commission before choosing a dwelling21.

How do septic permits work in Boone County?

The Northern Kentucky Health Department evaluates, permits and inspects onsite septic systems in Boone County.

The Northern Kentucky Health Department evaluates, permits and inspects onsite septic systems in Boone County3. Start with a $300 site evaluation; only a site rated suitable or provisionally suitable can move to an installation-permit application, and repairs or alterations require their own evaluation and permit3. After installation, the installer must request the Health Department inspection before any work is covered3. Local building-code offices also require a Health Department inspection of an existing septic system before issuing a building or remodeling permit; if the system is failing, request a site evaluation instead3. Only 0.2% of Boone County soils rate without severe limits for a conventional drain field, so make the site evaluation an early contingency9. The Health Department is at 8001 Veterans Memorial Drive, Florence, KY 41042, phone 859-341-42643.

Can you live in an RV or tiny home on your land in Boone County?

We could not confirm a general rule allowing long-term RV or tiny-home occupancy on private land in unincorporated Boone County.

We could not confirm a general rule allowing long-term RV or tiny-home occupancy on private land in unincorporated Boone County. Unincorporated Boone County expressly prohibits operating a short-term rental in an RV, tent, garage, boat or other area that is not a primary dwelling8. A short-term rental in a qualifying dwelling in unincorporated Boone County requires a county permit and occupational license, zoning approval, paved off-street parking and at least 1,000 feet from another approved short-term rental22. Mobile-home and RV parks require health permits and are inspected, but that rule does not answer whether an individual RV or manufactured home may be occupied on a private parcel23. Give the Planning Commission the parcel address and ask about the proposed dwelling, temporary construction occupancy, setbacks and minimum dimensions21,24.

What are the steps to build a home in Boone County?

For unincorporated Boone County, ask the Planning Commission to confirm the zoning district and proposed use.

  1. For unincorporated Boone County, ask the Planning Commission to confirm the zoning district and proposed use2,21.
  2. If public sewer is unavailable, obtain the Northern Kentucky Health Department's septic site evaluation and installation permit before construction; an existing septic system needs inspection before a building or remodeling permit is issued3.
  3. Arrange driveway approval through Boone County Public Works for work on county-owned rights-of-way, or the KYTC District Engineer for a state-highway driveway4,5.
  4. Obtain the Planning Commission's zoning permit before applying online to the Boone County Building Department1.
  5. Wait for building-permit issuance before starting work, report plan changes and schedule required inspections during construction1,15.
  6. Have the septic installation inspected before backfilling25.

What should you check before buying land in Boone County?

Check the flood map first because development in an identified Kentucky floodplain requires state and local permits.

Check the flood map first because development in an identified Kentucky floodplain requires state and local permits26. An accessory-structure application also requires specified flood or stream approval when any of the parcel lies in the designated floodplain or near a qualifying blue-line stream without mapped flood elevations27. Order the septic site evaluation before treating a homesite as buildable: only 0.2% of Boone County soils rate without severe limits for a conventional drain field9. Confirm legal road access and road ownership because county and state approaches use different approval paths5,27. Boone County is 58.7% wooded, while 37.3% of its land has a slope of 15% or less, so verify clearing, grade and drainage on the parcel9. Confirm sewer or water availability directly with the serving utility; we could not confirm one countywide connection rule.

Watch-outs

  • Kentucky's owner-builder paths are narrow: qualifying plumbing and HVAC work must be personally performed, with advance applications and required supporting documents6,7.
  • A new septic installation must be inspected before work is covered, while an existing system must be inspected before a Boone County building or remodeling permit is issued3.
  • A driveway approval depends on road ownership: county-owned rights-of-way go through Boone County Public Works' encroachment permit, while state-highway driveways go through the KYTC District Engineer4,5.
