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

Whether unincorporated Greene County, Mississippi requires a residential building permit remains unconfirmed because the county publishes no permit office or process¹.

Septic permits go through the Mississippi State Department of Health³.

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

Greene County does not publish a residential building-permit office or process, so the permit requirement for a home in unincorporated Greene County remains unconfirmed.

Greene County does not publish a residential building-permit office or process, so the permit requirement for a home in unincorporated Greene County remains unconfirmed¹. Mississippi directs counties and municipalities to enact uniform building codes unless they opted out before November 30, 2014, but that statewide framework does not establish whether Greene County opted out or presently enforces a residential code². Ask the Greene County Board of Supervisors what building approval, code, inspection and occupancy steps apply before ordering plans or beginning work^1,9.

Who handles building permits in Greene County, and how do you reach them?

No dedicated Greene County building department, code office or residential permit process could be confirmed.

No dedicated Greene County building department, code office or residential permit process could be confirmed¹. Start with the Greene County Board of Supervisors at (601) 394-5922 and ask which county official handles construction approval for the parcel, whether Greene County opted out of the state code framework, what code applies, when inspections occur and whether occupancy approval is needed^2,9. Do not assume that the absence of a published department means no building permit is required¹. Wastewater is separate: the Mississippi State Department of Health handles on-site wastewater work in Greene County^3,10.

Does Greene County have zoning?

Greene County is recorded as having no general countywide zoning because its official department roster lists no planning, zoning or code-enforcement office, but no explicit county statement rejecting zoning was confirmed⁴. The county does regulate mobile home parks: a park must contain at least 2 acres, may have no more than 50 mobile homes and may not exceed 5 spaces per gross acre⁵. Park setbacks are 50 feet in front and at least 25 feet at the side and rear, increasing to 50 feet where a side or rear yard abuts a public street⁵. These park standards do not answer setbacks or lot size for one mobile home on a private parcel. Ask the Board of Supervisors about that parcel's minimum dwelling size, setbacks and permitted uses^4,9.

How do septic permits work in Greene County?

The Mississippi State Department of Health administers individual on-site wastewater systems in Greene County, which is in the agency's South Region.

The Mississippi State Department of Health administers individual on-site wastewater systems in Greene County, which is in the agency's South Region³. A permit is required to install an on-site wastewater system, and the application covering the Notice of Intent and Final Approval has a $197.50 fee, subject to change and processing charges⁶. MSDH environmentalists provide soil and site evaluations and issue a permit or recommendation needed for a water meter¹⁰. The certified installer must notify MSDH 24 hours before installation and schedule the inspection; MSDH cannot grant final approval when installation occurred without inspection¹¹. Only about 16.1% of county soils are rated without severe limitations for a conventional drain field, so secure the parcel evaluation before fixing the house site or system budget¹².

Can you live in an RV or tiny home on your land in Greene County?

Greene County's rules for long-term RV occupancy, temporary camping and tiny-home occupancy on private land could not be confirmed.

Greene County's rules for long-term RV occupancy, temporary camping and tiny-home occupancy on private land could not be confirmed⁴. Minimum home size and the dimensional rules for an individual private parcel also remain unconfirmed; the county's confirmed acreage, density and setback standards apply to mobile home parks, not automatically to a single mobile home or tiny home⁵. Ask the Greene County Board of Supervisors for the rule applying to the parcel and proposed occupancy before buying land or moving a unit onsite^4,9. Wastewater must go to a central sewer or septic system, and gray water may not be discharged on the ground, into a ditch or into a body of water⁶.

Building a home in Greene County: the steps, in order

Ask the Greene County Board of Supervisors which building approval, code, inspection and occupancy requirements apply to the unincorporated parcel.

Ask the Greene County Board of Supervisors which building approval, code, inspection and occupancy requirements apply to the unincorporated parcel^1,9.

Confirm county and any applicable municipal land-use rules; mobile home parks have specific acreage, density and setback standards, while general parcel rules remain unresolved⁵.

Apply to MSDH for the on-site wastewater evaluation and permit or recommendation before choosing the final house and drain-field locations^6,10.

If acting as your own general contractor, confirm the state licensing exemption fits the project's ownership and use; the relevant exemptions limit covered owners to no more than 2 permit applications or single residences in 1 year⁷.

Obtain an MDOT driveway permit for access to a state highway, and ask the county about access from a county road¹³.

For a well with surface casing at least 6 inches in diameter, obtain the state groundwater-withdrawal permit unless an exclusion applies⁸.

What should you check before buying land in Greene County?

Start with wastewater feasibility because only about 16.1% of Greene County soils are rated without severe limitations for a conventional drain field.

Start with wastewater feasibility because only about 16.1% of Greene County soils are rated without severe limitations for a conventional drain field¹². Greene County receives about 62.9 inches of precipitation annually, so inspect drainage and evaluate the proposed house and septic areas under wet conditions¹². About 90.7% of county land has a slope of 15% or less, while about 83.5% is wooded; verify the individual tract rather than relying on county averages¹². Farmland value averages about $4,071 per acre, and the typical home value is about $166,305¹². The effective property-tax rate is about 0.8%, with a median annual bill of about $767¹². Before closing, confirm legal access, floodplain requirements, wastewater feasibility and every applicable building or land-use approval with the responsible offices^1,3.

Watch-outs

Do not treat the lack of a published building office as a permit exemption; Greene County's residential building-permit process and uniform-code status remain unconfirmed^1,2.
Greene County's mobile home park standards do not establish the lot size or setbacks for one mobile home on an individual parcel⁵.
A permanent water connection requires an approved sewage-disposal solution, either sewer or septic³.
Gray water may not be discharged on the ground, into a ditch or into a body of water; it must go to central sewer or septic⁶.
