Building permits, zoning and septic rules in Daviess County, Kentucky

Yes. New building construction, additions and certain remodeling in the Daviess County area administered by the Owensboro Metropolitan Planning Commission require construction-plan review after an application is received¹. The Building & Electrical Division issues building, electrical, HVAC, sign and parking-lot permits¹. Kentucky's residential code governs single-family homes, two-family homes and townhouses, with Kentucky amendments controlling where they conflict with the underlying code⁶. Project requirements depend on zoning, proposed use, building scale, land area, parking, landscaping and vehicular access, so begin with OMPC's preliminary review¹. Whitesville uses a separate process for residential construction of 12 units or fewer, so projects there should begin with the City Clerk¹.

The Owensboro Metropolitan Planning Commission's Building & Electrical Division handles building and electrical permits in the Daviess County area it administers¹. Reach the division at 270-687-8650 or visit 200 E. 3rd Street in Owensboro, Kentucky, Monday through Friday from 8:00 a.m. to 4:30 p.m¹.. The division issues building, electrical, low-voltage, HVAC, sign and parking-lot permits, and certificates of occupancy¹. New construction, additions and remodeling in the OMPC-administered area require at least three field inspections: footer-foundation, framing and final inspection for occupancy¹. Whitesville separately oversees residential construction of 12 units or fewer¹. Building permits and zoning approval stay with OMPC (or the Whitesville City Clerk), but septic permits do not move to either one: onsite sewage permits come from the Green River District Health Department, whichever office handles the building permit².

Yes. OMPC reviews development plans for compliance with the zoning ordinance in Owensboro and Daviess County, while the Whitesville City Clerk oversees the stated process in Whitesville¹. For a proposed home, confirm that the parcel is an appropriately zoned lot of record before applying; adopted subdivision rules can make some divisions of existing property impossible⁷. We could not confirm countywide minimum dwelling size, minimum lot size, setbacks, height, lot coverage, accessory-dwelling rules or an agricultural building exemption. Ask OMPC for the parcel's zoning district and current standards, or ask the Whitesville City Clerk when the property is in Whitesville¹.

Green River District Health Department administers onsite sewage in Daviess County under Kentucky requirements². First determine whether public sanitary sewer reaches the parcel; if onsite sewage is needed, complete the site evaluation before applying for the building permit⁷. A septic construction permit requires a detailed drawing, specifications and fees after the evaluation, and normally expires one year after issuance unless extended⁸. Every covered system must be inspected by a certified inspector, with the installation inspection completed before backfilling⁸. The state onsite sewage permit fee is $50, plus any additional fee set by the local board of health⁹. A homeowner may apply to build or alter the septic system for a qualifying personal-use residence, doing the work personally except for excavation and backfilling a certified installer may perform if disclosed, and is limited to one such permit per 5 years¹⁰. Only about 10% of Daviess County soils rate free of severe limitations for a conventional drain field, so the evaluation can materially affect the build plan and budget⁴. We could not confirm current health-department contact details; contact Green River District Health Department before relying on a timeline.

We could not confirm a Daviess County rule allowing or prohibiting residential RV occupancy, temporary camping or tiny-home occupancy on private land. Ask OMPC what the parcel's zoning district permits before buying land or moving a unit onto it¹. One placement rule is confirmed: in Daviess County outside Owensboro, a camping trailer or motor home on property of less than 1 acre may not sit on an unimproved surface for more than 7 consecutive days, unless it is inside a privacy fence or a garage or approved storage building¹¹. That rule governs parking, not whether anyone may live in the vehicle. In the agricultural zones, a manufactured home must connect to public water and sewer when available, otherwise the Daviess County Health Department must approve its sanitary sewer, and unsubdivided agricultural land is limited to one dwelling unit per 10 acres¹². Kentucky's rule for sleeping temporarily in a lawfully parked vehicle on a public road, street or parking lot applies only for less than 12 hours and does not answer whether someone may live in an RV on private property¹³. A site-built tiny home falls within Kentucky's residential-code framework, and new construction in the OMPC-administered area requires the applicable building permit^1,6. We also could not confirm a local minimum dwelling size, so obtain the parcel-specific zoning answer before choosing plans.

1. Ask OMPC for a preliminary review covering zoning, use, building scale, land area, parking, landscaping and vehicular access¹.
2. Determine whether public sewer, water and gas can serve the lot⁷.
3. Where public sewer is unavailable, complete Green River District Health Department's septic site evaluation and obtain the construction permit before the building-permit application^2,7,8.
4. Ask OMPC to confirm driveway requirements for the specific road because no current countywide rule was confirmed¹.
5. If the site is in a floodplain, obtain the OMPC permit before repair, development or construction and ask whether a Kentucky stream construction permit is also required⁵.
6. Submit the building-permit application and construction plans required for review¹.
7. Schedule the required footer-foundation, framing and final inspections with the Building & Electrical Division¹.

Confirm that the parcel is a buildable lot of record, because adopted regulations can prevent some divisions of existing land⁷. Verify the zoning district, utility service, sewage option, driveway access and floodplain status before making an offer^1,7. Floodplain repair, development or construction requires an OMPC permit before work starts; improvements exceeding 50% of value must meet additional code and permit requirements⁵. Test the soil before assuming a conventional septic system will work: only about 10% of Daviess County soils rate free of severe drain-field limitations⁴. Daviess County's effective property-tax rate is about 0.9%, with a median annual bill near $1,595⁴. For a private well, Kentucky requires a Kentucky Certified Water Well Driller to construct, modify or abandon it, and the driller must file the required documentation afterward; we could not confirm a separate county well permit, so ask the Green River District Health Department¹⁴.
