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

Walthall County's general residential building-permit requirement, application process, fee schedule and inspection program could not be confirmed. Mississippi required counties and municipalities to enact uniform building codes unless they opted out, but the statewide rule does not establish whether Walthall County opted out or which code edition applies6. A local government may require and charge for a building permit before installation of a modular home or modular-home component2. Where the modular-home inspection rule applies, local officials may inspect site preparation, foundations and structural, mechanical, plumbing and electrical connections outside the state factory-built standards8. Ask the Walthall County Board of Supervisors which building permit and code rules apply before construction7. An owner-builder working on that person's own residence is exempt from residential-builder licensing, not from building permits, codes, inspections, septic permits or local approval; the statute also limits an owner to one permit application, or one single residence, within one year1113.

Who handles building permits in Walthall County?

No specialized Walthall County building department or building-permit office could be confirmed. Start with the Walthall County Board of Supervisors at 200 Ball Ave., Tylertown, MS 39667, or call (601) 876-4947 during its published weekday hours7. Ask whether the county requires a building permit for the proposed structure, whether it adopted or opted out of the statewide code framework, who receives the building-permit application, what fees apply, and which inspections or occupancy approval are required76. For a modular home, specifically ask whether the county requires an installation building permit and inspects site preparation, foundations or outside connections28. For property inside Tylertown, ask the town whether it issues the building permit or zoning approval; the Mississippi State Department of Health still administers the septic permit145.

Does Walthall County have zoning?

Available county information indicates that unincorporated Walthall County is not zoned, but no official zoning ordinance, zoning map or explicit county no-zoning statement was confirmed1. The rules for setbacks, minimum lot size, minimum dwelling size, building height, lot coverage, accessory dwellings and short-term rentals also could not be confirmed. Ask the Walthall County Board of Supervisors about zoning approval for the parcel and proposed use, then review deeds, easements and subdivision covenants in the land records7. State health review of wastewater systems for subdivisions does not establish a general Walthall County subdivision or plat-approval ordinance14. The Town of Tylertown lists planning and zoning among the services it provides, but we could not confirm its ordinance, districts or approval procedures3. For property inside Tylertown, ask the town about municipal zoning approval and building permits; septic permits remain with the Mississippi State Department of Health145.

How do septic permits work in Walthall County?

The Mississippi State Department of Health administers individual on-site wastewater systems in Walthall County, and its permit is required to install one45. Start with the Walthall County Health Department at 903 Union Road in Tylertown or 601-876-492415. A permanent water meter requires a permanent sewage-disposal solution, either sewer or septic; where public sewer is unavailable, apply to the health department for the required paperwork9. The residential application asks whether the applicant wants a department inspection, while financing, utilities or other authorities may separately require approval after installation16. The published Notice of Intent plus Final Approval fee is $197.50, subject to change and possible processing or other costs17. Only 19% of county soils are rated without severe limitations for a conventional drain field, so resolve the site and soil review early18.

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

Walthall County's rules for long-term RV living and tiny-home occupancy could not be confirmed. The indication that unincorporated Walthall County lacks countywide zoning does not by itself establish permission to occupy either type of dwelling1. Ask the Walthall County Board of Supervisors about occupancy, temporary use, setbacks, floodplain review and any structure-specific approval before buying land for that plan7. Wastewater rules still apply: all wastewater must go to a central sewer or septic system, and gray water may not be discharged onto the ground, into a ditch or into a body of water10. A permanent water meter also depends on an approved permanent sewage-disposal solution9. If the project is part of an RV campground or subdivision, state health review for the commercial development may apply14.

Building a home in Walthall County: steps in order

  1. Confirm whether the parcel is in unincorporated Walthall County or a municipality, then ask the Board of Supervisors what building-permit, building-code, inspection and occupancy rules apply76.
  1. For a modular home, ask whether a local installation building permit and limited local inspections apply28.
  1. Contact the Walthall County Health Department, determine whether sewer is available and complete the septic-permit process before requesting a permanent water meter159.
  1. Plan every wastewater stream for sewer or septic; ground discharge of gray water is prohibited10.
  1. If the driveway connects to a state highway, obtain the required driveway permit for a new drive or alteration12.
  1. An owner-builder working on that person's own residence is exempt from residential-builder licensing, but not from building permits, codes, inspections, septic permits or local approval11.

What should you check before buying land in Walthall County?

Resolve wastewater feasibility before closing because only 19% of Walthall County soils are rated without severe limitations for a conventional drain field18. If a sewer line is nearby, the applicant may be directed to connect and may need a rejection letter from the sewer provider before a septic application proceeds9. Confirm legal road access; a new or altered driveway onto a state highway requires a permit, while no county-road driveway requirement was established by the cited rule12. Ask the Board of Supervisors about building rules, floodplain administration, RV or tiny-home occupancy and parcel-specific land-use requirements7. Walthall County averages 63.2 inches of precipitation a year, so inspect drainage and usable building area19. About 65.8% of the county is wooded, making clearing and access costs parcel-specific20.

Watch-outs

  • Walthall County's general building-permit process and code-adoption status remain unconfirmed; the modular-home rule does not establish a building-permit requirement for every home26.
  • A permanent water meter requires an approved sewer or septic solution, and nearby sewer availability may affect whether a septic application can proceed9.
  • Only 19% of Walthall County soils lack severe limitations for a conventional drain field, so resolve septic feasibility before choosing a house site18.
