Unincorporated Campbell County, Kentucky requires a building permit before you erect, move, add to, or structurally alter a building1. Kentucky's residential code leaves single-family permits, inspections and certificates of occupancy to local ordinance, so ask Campbell County Planning, Zoning and Building Inspections which approvals and inspections your project needs2345. Septic permits and inspections go through the Northern Kentucky Health Department6.

Do you need a building permit in Campbell County, Kentucky?
Unincorporated Campbell County requires a building permit before a public or private building is erected, moved, added to or structurally altered1. Kentucky's residential code does not itself require permits, inspections or certificates of occupancy for a single-family dwelling unless local ordinance requires them234. The county requirement therefore controls the permit answer, but the available material does not establish the county's complete inspection schedule or whether it requires a certificate of occupancy for every single-family project; ask Planning, Zoning and Building Inspections before work begins5. Kentucky's statewide building and residential codes still govern covered construction12.
Who is the Campbell County building department, and how do you reach them?
Campbell County Planning, Zoning and Building Inspections provides building permits, planning, zoning and floodplain management for unincorporated Campbell County5. Reach the department at 1098 Monmouth St, Suite 343, Newport, KY 41071, call (859) 292-3880, or email [email protected]; the department says email may get a quicker response when call volume is high5. Ask for the permits, inspection stages and occupancy approval that apply to your specific project because Kentucky's single-family baseline makes those local-ordinance questions234. For work on a county-maintained road, the Campbell County Road Department has a separate road cut, utility and right-of-way permit13.
Does Campbell County have zoning?
Unincorporated Campbell County has zoning under Chapter 154 of the county code7. The available rules do not establish one countywide answer for RV living, tiny homes, accessory dwellings, minimum house size, lot size or setbacks, so have Planning, Zoning and Building Inspections identify the parcel's district and applicable use and dimensional standards before you buy5. Qualified manufactured homes receive a narrower protection: Campbell County cannot exclude them from a residential zone that permits single-family residences or impose compatibility standards more stringent than those for other single-family structures in that zone, but statutory qualification requirements and deed, covenant, subdivision and historic-property restrictions still apply10. Dividing land into lots generally needs planning-commission approval, with a conditional agricultural-use exception1415.
How do septic permits work in Campbell County?
The Northern Kentucky Health Department handles septic systems in Campbell County6. Start with a site-evaluation application and the $300 evaluation fee; after the site receives a suitable or provisionally suitable rating, a certified installer may submit the installation-permit paperwork and permit fee8. After installation, the installer must request a Health Department inspection before any work is covered16. Existing systems may also need inspection when the local building-code office requires one for building or remodeling, or when a buyer or seller requests one16. Only about 0.2% of Campbell County soils are rated without severe limits for a conventional drain field, so settle site suitability and system cost before finalizing a house location or land purchase17.
Can you live in an RV or tiny home on your land in Campbell County?
We could not confirm a Campbell County rule that generally allows long-term RV living or tiny-home occupancy on private land. Kentucky protects only temporary sleeping in a lawfully parked vehicle for less than 12 hours; that rule does not grant a right to use an RV as a residence18. Because unincorporated Campbell County has zoning, ask Planning, Zoning and Building Inspections whether the parcel's district permits the proposed use and what building, inspection and occupancy approvals apply7534. A qualified manufactured home is different from an RV or an unqualified tiny home and has state protection in residential zones that permit single-family residences, subject to qualification standards and private restrictions10.
Building a home in Campbell County: the steps, in order
- Ask Campbell County Planning, Zoning and Building Inspections to confirm the parcel's zoning district, allowed use, setbacks and required building, inspection and occupancy sequence534.
- If you need septic, submit a site-evaluation application and the $300 fee to the Northern Kentucky Health Department8.
- After a suitable or provisionally suitable site rating, have a certified installer apply for the septic installation permit, then request inspection before covering the work816.
- Obtain the county building permit before erecting, moving, adding to or structurally altering a building1.
- Obtain both state and local permits before developing in an identified floodplain11.
- Contact the Road Department before work in a county-road right-of-way13.
What to check before you buy land in Campbell County
Resolve septic suitability early because only about 0.2% of Campbell County soils are rated without severe limits for a conventional drain field17. Check mapped flood risk because identified-floodplain development needs both state and local permits11. If the property will use a private domestic, livestock or irrigation well, Kentucky does not require the owner to file a well-permit application or pay a well-permit fee, but construction, modification and abandonment must be performed by a Kentucky Certified Water Well Driller9. Confirm road access before closing: the county has a right-of-way process for county-maintained roads, while a new or additional farm or single-family driveway on a state highway requires written application to the state district engineer1319. Farmland value averages about $6,228 per acre, and the effective property-tax rate is about 1.1%2021.
Watch-outs
- Campbell County requires a building permit, but we could not confirm the complete local inspection schedule or certificate-of-occupancy rule; ask Planning, Zoning and Building Inspections before work begins1345.
- Do not cover a new septic installation before the Northern Kentucky Health Department inspects it16.
