Lowndes County, Mississippi requires building permits before construction begins, and the county Building Inspection Department reviews plans, conducts inspections and checks each permit for floodplain status1. We could not confirm any county zoning approval for unincorporated land, and the City of Columbus zones within its own limits2,3. Septic permits for every address come from the Mississippi State Department of Health, not the building office4,5.
Do you need a building permit in Lowndes County, Mississippi?
Yes.
Yes. Lowndes County requires permits before construction begins, and the Building Inspection Department issues building, mobile-home setup, mobile-home mover, electrical, plumbing and mechanical permits1. Lowndes County adopted the 2018 International Building Codes and the 2017 National Electrical Code, with exceptions, effective February 1, 20216. A later county agenda proposed newer codes, but the available record does not establish that the proposal became effective6. The department reviews plans and conducts inspections, but its published process does not provide a complete application checklist, building-permit fee schedule or review timeline1. Ask Building Inspection what plans, trade permits and fees apply to your project before ordering materials.
Building permits are the county’s to issue, but they do not cover septic: onsite wastewater permits stay with the state health department, and a county building permit does not replace city zoning approval inside Columbus3,5.
Who is the Lowndes County building department, and how do you reach them?
The Lowndes County Building Inspection Department is at 17 Airline Rd., Columbus, MS 39701, phone 662-329-5860.
The Lowndes County Building Inspection Department is at 17 Airline Rd., Columbus, MS 39701, phone 662-329-58601. The department reviews building plans, issues building and mobile-home permits, handles electrical, plumbing and mechanical permits, conducts inspections, and issues certificates of occupancy for construction1. The county page does not say that every project requires a certificate of occupancy, so ask the department when your particular building may be occupied1. Building Inspection also reviews permits for floodplain determination and provides information about properties in special flood hazard areas1. Lowndes County participates in the National Flood Insurance Program, but the available county material does not establish the complete floodplain-development standards1.
Does Lowndes County have zoning?
Lowndes County lists no county Planning or Zoning department, and the available county information indicates no countywide zoning ordinance for unincorporated land.
Lowndes County lists no county Planning or Zoning department, and the available county information indicates no countywide zoning ordinance for unincorporated land2. We could not confirm an explicit county statement or ordinance that settles zoning status, setbacks, minimum lot size, minimum dwelling size, lot coverage or building height. Ask Building Inspection to confirm the rules for the parcel before relying on the absence of a zoning department. Building permits, code review and floodplain review still apply even where a zoning restriction cannot be confirmed1. Inside the City of Columbus, zoning does exist: the city sorts land into residential, commercial and industrial districts under its Columbus Development Code3. Rules inside other municipalities can differ too, and we did not confirm them; the county Road Department's jurisdiction statement specifically distinguishes roads outside Columbus city limits10.
How do septic permits work in Lowndes County?
The Mississippi State Department of Health administers onsite wastewater permitting in Lowndes County, while the county health department is the local contact for inspection coordination.
The Mississippi State Department of Health administers onsite wastewater permitting in Lowndes County, while the county health department is the local contact for inspection coordination4,11. Apply for the state's soil and site evaluation and Permit/Recommendation before installing a septic system; that permit is also required to obtain a permanent water meter when septic is the sewage solution5. The current published fee for a Notice of Intent plus final approval is $197.50, subject to change and online processing costs5. Only about 3.3% of county soils rate free of severe limitations for a conventional drain field, so make septic feasibility a contract contingency7. Mississippi treats gray water as wastewater and requires it to discharge to sewer or septic, not onto the ground, into a ditch or into a body of water12.
Can you live in an RV or tiny home on your land in Lowndes County?
We could not confirm a Lowndes County rule that authorizes or prohibits long-term RV living, temporary camping or tiny-home occupancy on private land.
We could not confirm a Lowndes County rule that authorizes or prohibits long-term RV living, temporary camping or tiny-home occupancy on private land. The absence of a listed county zoning department is not enough to treat a parcel as unrestricted2. Ask Building Inspection about occupancy, utility and permit requirements before buying or moving a unit onto the property. Lowndes County issues mobile-home setup and mover permits, while Mississippi requires a factory-built home intended for habitation to pass the state installation inspection before occupation1,13. Any occupied setup also needs lawful wastewater disposal: Mississippi requires all wastewater, including gray water, to go to a central sewer or septic system12.
Building a home in Lowndes County: the steps, in order
Confirm whether the parcel is in unincorporated Lowndes County or a municipality, because local requirements can differ.
- Confirm whether the parcel is in unincorporated Lowndes County or a municipality, because local requirements can differ14.
- Ask Building Inspection to confirm zoning, setbacks, code requirements, plan documents, fees and inspection stages; the published county process is incomplete1.
- Obtain the building permit before construction and expect the county to review the permit for floodplain status1.
- Apply to the Mississippi State Department of Health for a septic soil and site evaluation and Permit/Recommendation before installation5.
- Confirm the water source. The available official material establishes permitting for public-supply wells but does not establish a blanket construction-permit rule for every private residential well9.
- If installing a manufactured home, obtain the county setup permit and complete the required state installation inspection before occupancy1,13.
- Get an MDOT permit for a new driveway connecting to a state highway; ask the Road Department about county-road access because no county driveway rule was confirmed10,15.
What to check before you buy land in Lowndes County

Make a satisfactory septic evaluation part of the purchase contract: only about 3.3% of Lowndes County soils rate free of severe limitations for a conventional drain field7. Check the floodplain before choosing a homesite because Building Inspection reviews permits for floodplain determination and provides information on special flood hazard areas1. The land is generally gentle but often wooded: about 95.7% lies at a slope of 15% or less, and roughly 59% is forested7. Farmland averages about $3,174 per acre, while the typical home value is about $187,5177. The median property-tax bill is about $1,008 per year at an effective rate near 0.6%, and typical annual home insurance is about $1,6687. Confirm legal access and any driveway approval before closing; MDOT regulates connections to state highways, while no county-road driveway rule was confirmed10,15.
Watch-outs
- Do not start construction before Lowndes County issues the required permit; the county also reviews permits for floodplain status1.
- Lowndes County does not publish a complete building-permit checklist, fee schedule or review timeline, so get project-specific requirements from Building Inspection before budgeting1.
- Do not discharge gray water on the ground: Mississippi classifies it as wastewater and requires disposal through sewer or septic12.
