Winston County, MS: No Zoning, Owner-Builder Allowed

Winston County, Mississippi does not publish a building-permit office or process, so we could not confirm how residential permitting is handled in unincorporated areas¹. The county department list also does not establish whether a county zoning ordinance applies, although the City of Louisville has its own zoning ordinance for land inside the city^2,3. Septic permits and site evaluations go through the Mississippi State Department of Health^4,5.

Do you need a building permit in Winston County, Mississippi?

Winston County does not publish a residential building-permit office, application or inspection process, so a permit requirement for a particular unincorporated parcel could not be confirmed.

Winston County does not publish a residential building-permit office, application or inspection process, so a permit requirement for a particular unincorporated parcel could not be confirmed¹. Mississippi's statewide framework says counties and municipalities had to enact uniform building codes unless they opted out before November 30, 2014, but that framework does not establish Winston County's current code status⁸. Before ordering plans or starting site work, give the Winston County Board of Supervisors the parcel number, project type and intended use and ask whether a county permit, inspection or approval applies; the Board is the county body that adopts ordinances and regulations⁶. A project inside Louisville or another municipality needs a separate check with that city because a city rule does not answer what applies in unincorporated Winston County². Mississippi's owner-builder licensing exemption lets an owner who builds or supervises work on property for the owner's own use skip contractor licensing, but it is a licensing rule and does not by itself waive a locally required building permit or inspection⁹.

Who handles building permits in Winston County?

No dedicated Winston County building or planning office could be confirmed from the county's published department information.

No dedicated Winston County building or planning office could be confirmed from the county's published department information^1,2. The practical local starting point is the Winston County Board of Supervisors, which adopts county ordinances and regulations and oversees county roads and bridges⁶. Ask the office to identify any permit authority, adopted building code, required inspections, floodplain contact and county-road driveway approval for the exact parcel. For wastewater, contact the Mississippi State Department of Health's Division of On-Site Wastewater; Winston County is listed in its North Region, and the division accepts applications and provides soil and site evaluations^4,10. Keep written answers with the deed and construction records, especially if the county says no local building approval is needed.

Does Winston County have zoning?

We could not confirm a countywide zoning ordinance, zoning map or zoning districts for unincorporated Winston County from an official source.

We could not confirm a countywide zoning ordinance, zoning map or zoning districts for unincorporated Winston County from an official source². That gap is not proof that every rural parcel is unrestricted. The same review did not confirm county rules for minimum lot size, setbacks, building height, manufactured homes or accessory dwellings. Ask the Winston County Board of Supervisors what ordinance applies to the parcel and whether another authority has jurisdiction⁶. The City of Louisville has adopted a zoning ordinance with 11 districts and an official zoning map, but that ordinance covers only land inside the city and does not set rules for unincorporated Winston County³. Land inside Louisville or another incorporated municipality may be governed by that municipality rather than the county, so confirm the parcel's jurisdiction before relying on an answer about unincorporated land². Septic siting remains regulated even where zoning is not confirmed, and wastewater must go to a central sewer or septic system rather than being discharged as gray water⁵.

How do septic permits work in Winston County?

The Mississippi State Department of Health administers onsite wastewater permitting for Winston County.

The Mississippi State Department of Health administers onsite wastewater permitting for Winston County⁴. A permit is required for installation of an onsite wastewater system and for obtaining a permanent water meter⁵. Properties within one mile of a sewer line may be referred to connect, and the septic application may require a rejection letter from the sewer provider⁵. File the application, submit the requested documents, pay the applicable fee and prepare for a property visit⁴. The published charge for a Notice of Intent plus Final Approval is $197.50, while fees and online-processing costs can change⁵. A certified installer must contact the department 24 hours before construction begins to schedule an inspection¹¹. Only 5.2% of Winston County soils lack severe limitations for a conventional drain field, so complete the evaluation before fixing a house site or purchase budget⁷.

Can you live in an RV or tiny home in Winston County?

We could not confirm an official Winston County rule that allows or prohibits full-time RV living, temporary camping or tiny-home occupancy on private land.

We could not confirm an official Winston County rule that allows or prohibits full-time RV living, temporary camping or tiny-home occupancy on private land. Ask the Winston County Board of Supervisors about the specific parcel, intended duration, structure type and utility plan before buying or moving a unit onto the site⁶. If the parcel is inside a municipality, ask that municipality as well because county information does not establish city land-use rules². Regardless of the dwelling type, Mississippi treats gray water as wastewater: household wastewater cannot be released onto the ground, into a ditch or into a body of water and must be piped to a central sewer or septic system⁵. An RV-park or campground rule does not answer whether one RV may be occupied on private rural land, so get a parcel-specific answer in writing.

What are the steps to build a home in Winston County, in order?

Confirm whether the parcel is inside a municipality or in unincorporated Winston County, because the county's published information does not establish one zoning answer for every location.

Confirm whether the parcel is inside a municipality or in unincorporated Winston County, because the county's published information does not establish one zoning answer for every location².

Give the Winston County Board of Supervisors your parcel and project details, then ask for the applicable building, inspection, floodplain and county-road access requirements^1,6.

Contact the sewer provider if a line is nearby; applications within one mile of a sewer line may be referred for connection before septic review continues⁵.

Apply to the Mississippi State Department of Health for the onsite wastewater permit and site evaluation before locking in the house location^5,10.

Hire a certified installer and have the installer give the department 24 hours' notice before construction for the required inspection¹¹.

If the driveway connects to a state highway, obtain the required Mississippi Department of Transportation permit before building or altering the drive¹².

What should you check before buying land in Winston County?

Start with septic feasibility.

Start with septic feasibility. Only 5.2% of Winston County soils lack severe limitations for a conventional drain field, so a low purchase price can be offset by a difficult system design⁷. Confirm whether sewer is available because a property within one mile of a line may be directed toward connection⁵. Verify legal access and ask the Board of Supervisors about a driveway onto a county road; the Board oversees county roads and bridges⁶. A new or altered driveway onto a state highway requires a state permit¹². If you plan a well, state law requires a groundwater withdrawal permit for water wells with a surface casing diameter of 6 inches or more, with some exclusions, so ask the Mississippi State Department of Health or the Board of Supervisors what applies to a household well¹³. Check flood maps and ask the Board to identify the local floodplain contact because a Winston County floodplain permit process was not confirmed. Finally, price clearing and drainage: 83.2% of the county is wooded, 78.2% of the land has a slope of 15% or less, and annual precipitation is about 57 inches⁷.

Watch-outs

Do not treat the absence of a published county permit office as permission to build; ask the Winston County Board of Supervisors for a parcel-specific answer^1,6.
A permanent water meter depends on an approved sewage-disposal path, and a nearby sewer line can change whether a septic application proceeds⁵.
Winston County's RV, tiny-home, setback and minimum-size rules could not be confirmed; ask the county or the municipality with jurisdiction before purchase².

SetbacksSpecified
Individual on-site wastewater disposal systems using aggregate disposal systems in Mississippi.
- The 50-foot measurement is the minimum distance from the water edge for all listed non-gravel soil textural classes and for slopes both less than and more than 8 percent.
- Gravel is marked "NOT APPLICABLE."
- The regulation states that these setbacks apply to all individual on-site wastewater disposal systems except spray-irrigation disposal and overland discharge.
- This is an on-site-wastewater setback, not a statewide zoning setback for the dwelling or other structures.
minimum distance from water edge: 50 feet (Aggregate systems in coarse sand, medium sand, fine sand, loamy sand, sandy loam, light loam, heavy loam, silt loam, sandy clay loam, light clay loam, heavy clay loam, light silty clay loam, heavy silty clay loam, sandy clay, silty clay, and clay; both slope categories shown in Table 1.)

A tiny house or home intended for use as a residential dwelling that is within the State Fire Marshal's factory-built-home regulation.
- The defined tiny house or home ranges from 80 to less than 400 square feet and may or may not be constructed on a chassis with or without axles or wheels.
- If intended as a residential dwelling, it is treated as a modular home for design and construction requirements and must comply with the most current residential building code adopted by the Mississippi Building Codes Council.
- When designed for permanent installation at its final destination, it must be installed on an approved foundation complying with the manufacturer's installation guidelines concerning manufacturing-facility and retail-entity licensure and occupant-safety installation standards.
- The amended regulation superseded prior versions and became effective July 1, 2026.
