Owner-builders may build or oversee work on their own residence without a residential-builder license, but that does not waive local permits4.

Do you need a building permit in Prentiss County, Mississippi?
Whether Prentiss County requires a building permit is unconfirmed by this guide: Mississippi law directs every county to require permitting as a condition of construction in unincorporated areas, but Prentiss County's own government site lists no building or permitting department among the departments under its Board of Supervisors18. Separately, a 2014 state law required every county and municipality to enact a uniform building code unless it opted out before November 30, 2014, though the source describing that framework does not confirm which counties currently have an adopted code9. If you plan to build your own home, Mississippi's residential builder and remodeler licensing law does not apply to a person building or acting as general contractor on their own residence, though that licensing exemption does not by itself waive any building permit or inspection a local government requires4. Call the Prentiss County Board of Supervisors directly before you assume either answer8.
Who handles permits, roads and floodplain questions in Prentiss County, and how do you reach them?
Prentiss County's general government contact is the Board of Supervisors at 100 North Main Street, PO Box 477, Booneville, MS 38829, phone 662-728-46108. The published county department list has no building, planning, zoning or floodplain department, so start permit questions with the Board of Supervisors8. The Prentiss County 911 Office issues new addresses to people building or placing mobile homes; it is at 101 N College ST, Booneville, MS 38829, phone 662-728-178410. County-road, bridge, drainage, culvert and right-of-way questions go to the Road Department at 100 North Main Street, phone 662-728-461011. For flood-related concerns, contact Prentiss County Emergency Management at PO Box 477, Booneville, MS 38829, phone 662-728-8198 or [email protected]; we could not confirm a separate county floodplain administrator12.
Does Prentiss County have zoning?
Whether Prentiss County has adopted zoning for unincorporated land is unconfirmed: no planning or zoning office appears among the county's departments, and no authoritative county page confirms or denies a county zoning ordinance28. Zoning in this part of Mississippi is more clearly established inside cities such as Booneville, the county seat, but municipal zoning does not extend to unincorporated land2. Mississippi's own guidance to new businesses says permits and requirements for construction or land development "may be required from city or county governments" and differ by location, which is consistent with needing to check directly rather than assume either a zoned or unzoned answer13. Because this guide could not confirm a zoning rule, don't assume you have a setback, minimum-lot-size, or RV/tiny-home answer either way; call the Board of Supervisors8.
How do septic permits work in Prentiss County?
Septic permitting in Prentiss County is handled by the Mississippi State Department of Health, which performs the site and soil evaluation3. The Division of On-Site Wastewater is at 570 East Woodrow Wilson Drive, Jackson, MS 39216, phone 601-576-7150, and accepts documents at [email protected]14. State rules require installers to arrange inspection with the appropriate county Department of Health15. Only about 5.1% of Prentiss County soils are rated without severe limitations for a conventional septic drain field, so get the site evaluation before assuming a standard system will work16. A permanent water connection requires permanent sewage disposal; if public sewer is unavailable, apply to MSDH, while an application within one mile of a sewer line is referred to that sewer provider first17. Mississippi does not treat gray water as a separate disposal category: wastewater must enter a central sewer or septic system and cannot be discharged onto the ground, into a ditch or into water7.
Can you live in an RV or tiny home on your land in Prentiss County?
We could not confirm a Prentiss County rule allowing or prohibiting residential RV use, temporary camping or tiny-home occupancy on unincorporated land2. Ask the Prentiss County Board of Supervisors about land use, setbacks and any dwelling-size rule before buying or moving a unit onto a parcel8. A tiny home still needs an approved wastewater plan: Prentiss County's onsite systems go through the Mississippi State Department of Health3. An RV also cannot rely on outdoor gray-water discharge, because Mississippi requires wastewater to enter a central sewer or septic system and does not recognize gray water as a separate disposal category7. If you are placing a mobile home rather than an RV, obtain the new address from the Prentiss County 911 Office10.
Building a home in Prentiss County: the steps, in order
- Call the Prentiss County Board of Supervisors to ask whether your parcel needs a building permit, zoning approval or floodplain review; we could not confirm those county processes812.
- Get a new address from the Prentiss County 911 Office if you are building or placing a mobile home10.
- Apply to the Mississippi State Department of Health for the septic permit and site evaluation314.
- Obtain a state groundwater-withdrawal permit if the well has surface casing at least 6 inches in diameter, subject to exclusions5.
- Get an MDOT permit for a new or altered driveway connecting to a state highway; coordinate county-road drainage and culverts with the Prentiss County Road Department611.
- Owner-builders may oversee work on their own residence without a residential-builder license, but that exemption does not cancel required permits4.
