Do you need a building permit in Perry County, Mississippi?
Perry County's residential building-permit requirement and local application process could not be confirmed1. The Mississippi Insurance Department says all counties and municipalities must enact uniform building codes unless they opted out before the 2014 deadline, but that source does not show whether Perry County opted out or what code it enforces.1011 Do not market rural land as permit-free or code-free. Before ordering plans or starting site work in unincorporated Perry County, ask the Board of Supervisors who accepts residential permit applications, which code applies, what inspections are required, what the fees are and whether a certificate of occupancy is issued2. Incorporated places may administer their own requirements, so contact the relevant city when a parcel is inside municipal limits12.
Who handles Perry County building permits, and how do you reach them?
Perry County does not publish a dedicated building department, application, fee schedule or inspection process, so the local construction path could not be confirmed1. Start with the Perry County Board of Supervisors at 101 Main St. in New Augusta, by phone at 601.964.8370 or email at contact@perrycountyms.gov2. Ask the Board office to identify the current building and floodplain officials, then get parcel-specific requirements in writing. For an entrance on a county road, the Perry County Engineer is the public-infrastructure contact and handles questions involving county roads, bridges and drainage13. A driveway connecting to a state highway requires an MDOT permit14.
Does Perry County have zoning?
Unincorporated Perry County does not have county-level zoning3. That does not settle every parcel question: county standards for setbacks, minimum lot size, minimum dwelling size, building height and lot coverage could not be confirmed. Ask the Board of Supervisors for a parcel-specific written answer before relying on a seller's description2. If the land lies inside an incorporated municipality, contact that city because Mississippi permit and zoning requirements vary by local government12. The county's floodplain-development permit requirement and current administrator also could not be confirmed, so ask the Board office before placing improvements in a mapped flood area2.
How do septic permits work in Perry County?
The Mississippi State Department of Health administers individual on-site wastewater systems in Perry County4. A permanent sewer or septic solution is required before a permanent water meter can be connected, and an MSDH permit is required for an onsite system155. MSDH reviews the application before invoicing, emails the invoice within one business day and requires payment before visiting the property16. Current online fees are $197.50 for Notice of Intent plus Final Approval or $100 for Notice of Intent plus Exemption; processing fees may apply and charges can change17. The exemption route does not include an MSDH approval visit after installation18. Start with the Perry County Health Department at 601-964-328819. Only about 33.3% of county soils lack severe limitations for a conventional drain field, so evaluate the site before fixing the house location or wastewater budget8.
Can you live in an RV or tiny home on your land in Perry County?
Perry County does not have county-level zoning in unincorporated areas, but long-term RV occupancy, temporary camping and tiny-home occupancy still could not be confirmed3. Ask the Board of Supervisors about residential occupancy, construction, address assignment and floodplain review before moving onto the parcel2. For wastewater purposes, MSDH treats a hunting camp as a residential application; a hunting-camp property with three or more trailers, cabins or RVs requires a commercial-development application7. Mississippi does not recognize gray water as a separate waste stream: all wastewater must discharge to sewer or septic, not onto the ground, into a ditch or into water20. The owner-builder exemption removes a state residential-builder licensing requirement for work on your own residence, but it does not waive permits or other rules6.
Building a home in Perry County: the steps, in order
- Ask the Perry County Board of Supervisors to identify the current building, inspection and floodplain authorities for the parcel2.
- If the parcel is inside a municipality, confirm that city's separate requirements before design work12.
- Confirm entrance approval with the County Engineer for a county road or obtain an MDOT permit for a state-highway connection1314.
- Submit the residential permit documents the county identifies and schedule required inspections; Perry County's exact process remains unconfirmed1.
- If acting as your own general contractor on your own residence, document the state licensing exemption while following every applicable permit rule6.
What should you check before buying land in Perry County?
Start with wastewater: only about 33.3% of Perry County soils lack severe limitations for a conventional drain field, so obtain the state site evaluation before assuming a standard system will fit85. If land will be divided, MSDH reviews onsite-wastewater designs for subdivisions, but that does not establish whether Perry County separately regulates plats or subdivision layout21. Check access next: the County Engineer handles county-road infrastructure questions, while a new driveway onto a state highway requires an MDOT permit1314. Confirm setbacks, dwelling type, RV use and floodplain review with the Board of Supervisors even though unincorporated Perry County lacks county zoning32. Perry County is about 88.1% wooded and about 41.8% federally owned, so verify surveyed boundaries and legal access2223.
