Building permits, zoning and land rules in Hinds County, Mississippi

Buildings, manufactured homes, additions, moves and structural alterations in unincorporated Hinds County require a permit from the Director of Permit and Zoning¹. Hinds County reviews permits for conformity with its zoning ordinance, the Southern Standard Building Code and other applicable laws, while the department's current home notice calls for the 2018 International Residential Code^1,6.

A county handout exempts a farm building on more than ten acres used for intensive agriculture as defined by the zoning ordinance⁴. County permits remain valid for two years, but work must begin within six months⁴. Hinds County checks construction and use conversions for compliance, issues the certificate of occupancy after final inspection, and bars occupancy of new structures and major alterations until that certificate is issued¹.

Mississippi's owner-builder exemption can remove the residential-builder licensing requirement when a person builds or improves that person's own residence, but it does not remove the county permit or inspection requirements⁸. Confirm the exemption's limits with Permit & Zoning before applying.

Inside Jackson, the city issues building permits; MSDH still handles individual on-site wastewater systems^3,9.

The Hinds County Permit & Zoning Department handles building permits and zoning for unincorporated Hinds County; call (601) 355-5424 or apply through the county's online portal after creating an account². A residential application requires two complete plan sets⁴. The published process calls for a completed application, plot diagram and supporting information; projects that need site-plan review must finish that review before the building permit is issued¹.

The county building and zoning guidance here applies to unincorporated land². MSDH handles on-site wastewater; its application-help line is 1-855-220-0192^3,10. Hinds County Public Works handles county roads, driveway culverts, utility permits and subdivision inspections at 900 East Main Street, Raymond, 601-857-8732¹¹. A driveway connecting to a Mississippi state highway needs an MDOT permit¹².

The Hinds County Zoning Ordinance governs unincorporated land, while incorporated municipalities may administer different rules². Hinds County divides unincorporated land into zoning districts with separate regulations². Jackson and Clinton set their own zoning; MSDH handles on-site wastewater paperwork, with Clinton also imposing local sewage restrictions^3,5,13,14.

Lot size, setbacks, height and coverage depend on the parcel's district and use. R-1A requires one acre per residential unit, with a 50-foot front yard, 20-foot side yards and a 50-foot rear yard¹. One district provision caps all buildings at 50% of gross lot area, and R-1A allows a height of 35 feet or two and one-half stories¹. The multifamily provision sets minimum floor area at 500 square feet for one bedroom, 700 square feet for two bedrooms and 900 square feet for three or more bedrooms; those figures are not a countywide minimum for every house¹. Ask Permit & Zoning for the parcel's district before sizing a home or positioning improvements.

The Mississippi State Department of Health administers on-site wastewater permits serving Hinds County³. A complete application and payment are required for a new individual system, and an MSDH permit is required for on-site wastewater installation and a permanent water meter^3,5. Call the wastewater application-help line at 1-855-220-0192¹⁰.

Where public sewer is unavailable, wastewater must go to an approved septic system; Mississippi treats gray water as wastewater and does not allow discharge onto the ground, into a ditch or into a body of water⁵. Only 9% of Hinds County soils avoid NRCS's very limited rating for a conventional drain field, so obtain the MSDH evaluation before fixing the house site^5,7.

Mississippi does not require an existing septic system to be inspected merely because real estate is changing hands, although MSDH recommends an inspection and a lender, buyer, seller, utility or local government may request one⁵. The MSDH residential application asks whether installation inspection is requested; financing, utilities or municipalities may require that inspection¹⁵. Advanced Treatment System tanks require inspection by a certified manufacturer's representative⁵.

Hinds County prohibits pre-constructed tiny homes and storage buildings meant for residential living in unincorporated areas, and it does not issue permits for pre-built buildings intended as dwellings⁶. A small house built on site must follow the 2018 International Residential Code and the ordinary county permit process^4,6.

The zoning ordinance prohibits using a travel trailer, camper or motor home for living, sleeping or housekeeping on a residential lot or anywhere not approved for that use¹. We could not confirm every circumstance in which temporary camping or RV occupancy might be approved, so ask Permit & Zoning about the parcel and proposed stay. Placing a travel trailer on property also requires a county permit¹.

Hinds County allows single-family manufactured homes in R-6 parks on an owner-occupied, rental or lease basis, with site-plan approval before a building permit and standards for foundations, tie-downs, utilities and setbacks¹. Manufactured-home parks require a building permit before utility connection; we could not confirm the placement rules for every parcel outside a park, so ask Permit & Zoning¹. A separate mobile-home permit costs $191 and requires utility and MSDH septic approval¹⁶.

1. Confirm that the parcel is unincorporated, then ask Permit & Zoning to identify its district and allowed use^1,2.
2. Confirm that the lot meets Hinds County subdivision rules; a family-subdivision preliminary plat must be approved before construction or a building permit¹.
3. Check flood status: Hinds County prohibits structures in designated floodways, and a flood-hazard parcel needs a professional engineer’s Flood Data Certificate with the building-permit application¹.
4. Apply to MSDH for the septic evaluation and permit if public sewer is unavailable⁵.
5. Secure written water approval, then prepare the plot plan, construction plans and supporting information^1,4.
6. Apply through the county portal; projects needing site-plan review must finish that process before the building permit issues^1,2.
7. Coordinate county-road access with Public Works or obtain state-highway access approval^11,12.
8. Complete the required inspections and obtain the certificate of occupancy before using the new structure¹.

Flooding: a building-permit application for property in a flood hazard area requires a Flood Data Certificate from a registered professional engineer¹. The county's procedure also requires two feet of freeboard and elevation certificates before construction-permit issuance, framing approval and final approval¹⁷.

Water: an MSDH Permit/Recommendation is required for a water meter when using on-site wastewater³. We could not confirm a general private-well construction permit rule; ask MSDH and Permit & Zoning before relying on a well.

Fit and access: verify the zoning district, allowed use, minimum lot area, setbacks, height, lot coverage and subdivision status rather than relying on one district's examples¹. Private family-subdivision roads do not qualify for county maintenance unless upgraded and accepted under county standards; conveying a lot outside the family triggers zoning and subdivision compliance before additional residence or manufactured-housing permits¹. Confirm road access with Public Works before closing¹¹.

Budget: farmland averages about $3,474 an acre and a typical home value is about $133,000⁷. The effective property-tax rate is about 0.9%, with a median annual bill of about $1,389⁷.
