Amite County, Mississippi requires a county development permit for work in regulated floodplain areas, but we could not confirm a general residential building-permit requirement outside that process1. We could not confirm countywide zoning either; the Town of Centreville has its own planning and zoning review23. Septic permits for every Amite County address go through the Mississippi State Department of Health, not the county or the town4.

Do you need a building permit in Amite County, Mississippi?
Amite County requires a development permit for work in or affecting a regulated floodplain1. Development includes buildings and structures as well as filling, grading, paving, excavating, drilling and permanent storage10. Floodway or flood-zone work may require engineering data, surveyed elevation certification and flood-proofing information11. We could not confirm whether Amite County requires a separate general residential building permit or general inspections outside the floodplain process, so ask county government before construction12. Mississippi law required counties and municipalities to enact uniform building codes unless they opted out before November 30, 2014, and the available material does not show whether Amite County adopted a code or opted out13. Septic permits are a separate state-run process, covered below4.
Who handles floodplain, building and septic permits in Amite County, Mississippi?
Amite County Emergency Management administers floodplain permitting and regulatory work; its office is at 185 Irene St. in Liberty and its phone number is 601-657-101114. The county directs applicants seeking a new 911 address to the Central Repair Facility at 720 Industrial Park Dr. in Liberty to complete the floodplain application15. The proposed driveway location must be marked so the county can locate it for addressing10. The floodplain application used to obtain a 911 address costs $20, payable by cash or check; that published amount is not a general building-permit fee schedule5. Septic permits are not issued by either county office; they come from the Mississippi State Department of Health, listed below16.
Does Amite County have zoning?
We could not confirm whether unincorporated Amite County has countywide zoning2. The Town of Centreville has a Planning and Zoning Commission that reviews zoning amendments, site plans and plat applications, so land in Centreville has a separate municipal review layer3. The town's Code Enforcement Division enforces its zoning and sanitation codes, though the town's zoning districts and dimensional standards were not published on the pages we could find17. Septic permits for a Centreville address still come through MSDH4. We could not confirm county rules for setbacks, minimum lot size, minimum dwelling size, building height or agricultural-building exemptions2. Ask county government about unincorporated parcels and the relevant town about land inside municipal limits18. MSDH also reviews wastewater for subdivisions, with its own lot-count and feasibility-study triggers19.
How do septic permits work in Amite County?
The Mississippi State Department of Health handles onsite wastewater permitting for Amite County through its South Region4. A complete application needs property documentation, a plot plan, a site and soil evaluation, and payment2021. Properties within one mile of a sewer line are referred to the sewer provider first, and MSDH may require a rejection letter before proceeding with septic20. An installation inspection can be requested and may be required by a lender, utility, municipality or another entity, but Mississippi does not require a septic inspection simply because property is being sold22. Only 7.8% of county soils are rated without severe limits for a conventional drain field, so settle wastewater feasibility before fixing the house site23.
Can you live in an RV or tiny home on land in Amite County?
We could not confirm an Amite County rule allowing or barring long-term RV living, tiny-home occupancy, temporary camping or a minimum dwelling size on private unincorporated land2. The county address application mentions proposed structure types, but the application is not an occupancy approval15. Mississippi does not treat gray water as a separate disposal category: wastewater must go to sewer or septic rather than onto the ground, into a ditch or into a body of water7. A local authority may allow a temporary portable toilet until septic is installed, but that does not answer whether residential RV or tiny-home occupancy is allowed7. A permanent water meter requires an available sewer or septic solution24.
Building a home in Amite County: what are the steps?
- Ask county government whether the parcel needs any general residential building approval in addition to the floodplain process12.
- Complete the county address/development-permit packet, mark the proposed driveway, and pay its published fee105.
- If the parcel is in Centreville, take zoning, site-plan or plat questions to the town's Planning and Zoning Commission3.
- Give MSDH the property documents and plot plan for its onsite wastewater site and soil evaluation21.
- Ask MSDH whether an installation inspection is requested or required for the project22.
What should you check before buying land in Amite County?
Check flood status with Amite County Emergency Management before choosing a homesite because regulated floodplain work can trigger engineering, elevation and flood-proofing documentation11. Arrange the MSDH site and soil evaluation early because only 7.8% of county soils are rated without severe limitations for a conventional drain field23. For a proposed well, ask the Mississippi Office of Land and Water Resources whether a Water Use Permit applies before drilling; permitted wells require completion information afterward and must be drilled by a state-licensed water-well contractor9. Confirm access separately because marking a driveway for addressing does not establish whether another access approval applies10. Budget for an effective property-tax rate of about 0.5% and a median annual bill of about $4352627.
Watch-outs
- A county floodplain development permit is documented, but a separate general home-permit, inspection or certificate-of-occupancy rule remains unconfirmed1.
- The county's published $20 fee applies to its floodplain application for a 911 address, not a published general building-permit fee schedule5.
- A permanent water connection requires a sewer or septic solution, and nearby sewer availability can affect whether MSDH proceeds with a septic application2420.
- Centreville has municipal planning and zoning review; do not treat the unconfirmed countywide zoning status as an answer for property inside town32.
- MSDH wastewater review applies to subdivisions, while Amite County's separate plat or land-division process remains unconfirmed19.
- Amite County's address packet asks for a $20 check or money order payable to "Amite county permit fee" mailed to P.O. Box 699, Liberty, MS 39645, while the FAQ describes paying in person by cash or check at the Central Repair Facility285.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
