Building permits, zoning and land rules in Lincoln County, Mississippi

Lincoln County does not publish a building department, building-permit office or county construction process, although Mississippi law directs counties to require permitting as a condition of construction in unincorporated areas¹. The practical answer is therefore unconfirmed, not an assumption that rural construction needs no building permit¹. Before ordering plans or starting site work, call the Lincoln County Administrator at 601-835-3421 and describe the parcel location, intended use and structure². Mississippi required counties and municipalities to enact uniform building codes unless they opted out before November 30, 2014, but the state source does not establish Lincoln County's choice or current code edition¹⁰. An owner working on their own residence may qualify for Mississippi's residential-builder licensing exemption, but that exemption does not waive a building permit or inspection requirement⁸.

For unincorporated Lincoln County, start with the County Administrator because that office administers any zoning and building-code ordinances adopted by the Board of Supervisors². The office is at 301 South First St., Room 202, Brookhaven, MS 39601, and the phone number is 601-835-3421². Inside Brookhaven, the city handles building permits and inspections; a building-permit application requires plans and a deed copy⁵. Brookhaven's Public Works Department and Building Inspector can be reached at 601-833-7766¹¹. Septic permits do not move to the city: MSDH administers onsite wastewater throughout Lincoln County⁶. For county-road culvert, ditch or right-of-way work, contact the Road Department¹². A driveway onto a state highway requires an MDOT driveway permit¹³.

Available county information describes unincorporated Lincoln County as unzoned, but we could not confirm a current county zoning ordinance³. Ask the County Administrator whether the Board of Supervisors has adopted any ordinance affecting the parcel, because that office administers county zoning and building-code ordinances when adopted². Do not treat the unzoned description as proof that a parcel has no setbacks, minimum lot size, building-height limit or minimum home size; those rules remain unconfirmed for unincorporated Lincoln County³. Inside Brookhaven, the city administers zoning and uses its zoning map to identify a parcel's district⁴. Brookhaven also requires building permits for specified work, and portable storage buildings must meet location and setback requirements⁵. MSDH, rather than the city zoning office, handles septic permits throughout the county⁶.

The Mississippi State Department of Health administers onsite wastewater systems throughout Lincoln County^6,14. A new septic system requires a complete application, documentation and fee, followed by a soil and site evaluation before MSDH issues the Permit/Recommendation⁷. The certified installer must contact MSDH 24 hours before construction to schedule the installation inspection⁷. Acreage exemptions can change whether Final Approval is required, but the application, evaluation, Permit/Recommendation and inspection steps still apply⁷. The current Notice of Intent plus Final Approval fee is $197.50; fees can change and online payment adds a processing fee¹⁵. Only 0% of mapped Lincoln County soils are rated free of severe limitations for a conventional drain field, so make the site evaluation a purchase contingency⁹.

Long-term RV occupancy and tiny-home occupancy on private land in unincorporated Lincoln County could not be confirmed from a county rule^1,3. The county's unzoned description does not answer sanitation, utility, building-code or occupancy questions³. Before buying land for either use, ask the County Administrator whether an ordinance applies to the parcel and proposed living arrangement². Mississippi treats gray water as wastewater: it must enter a central sewer or septic system and cannot be discharged onto the ground, into a ditch or into a body of water¹⁵. Inside Brookhaven, city zoning applies, so use the zoning map and ask the city how it classifies the proposed unit⁴. Septic permitting for an RV or tiny-home site remains with MSDH even inside Brookhaven⁶.

1. Call the County Administrator to confirm whether the unincorporated parcel needs a building permit, code review, inspection or fee^1,2.

1. Apply to MSDH for the septic site and soil evaluation before fixing the house, well and driveway locations⁷.

1. Obtain the septic Permit/Recommendation, then have the certified installer schedule the required installation inspection 24 hours before construction⁷.

1. If a planned well has a surface casing diameter of 6 inches or more, confirm and obtain the state groundwater-withdrawal permit unless an exclusion applies¹⁶.

1. Contact the Road Department before work on a county-road culvert, ditch or right-of-way; obtain an MDOT driveway permit for a connection to a state highway^12,13.

1. Inside Brookhaven, use the city's zoning map and building-permit process, but continue to use MSDH for the septic permit^4,5,6,11.

Make septic feasibility the first contingency: 0% of mapped soils are rated free of severe limitations for a conventional drain field, and MSDH recommends applying before other work because system placement can control the whole site plan^9,17. Verify whether public sewer is available, because a permanent water meter requires an approved permanent sewage solution and public sewer changes the application path¹⁵. Confirm whether access is from a county road or state highway, since county right-of-way work goes through the Road Department while a state-highway driveway needs an MDOT permit and an approved plan^12,13. Lincoln County's typical effective property-tax rate is about 0.7%, and the median annual bill is about $945⁹. The county receives about 60.4 inches of precipitation annually, while 83.5% of its land has slopes of 15% or less and 74.3% is wooded; inspect drainage, clearing needs and the actual homesite rather than relying on county averages⁹.
