Do you need a building permit in Harrison County, Texas?

An ordinary single-family home on unincorporated Harrison County land does not need a general county building permit1. Construction or substantial improvements in a flood hazard area require a floodplain development permit before work or structure placement begins2. Harrison County publishes a $20 application fee for residential and commercial floodplain development; residential application fees are non-refundable1314. The residential packet requires plans, proof of ownership, directions and a FEMA Elevation Certificate prepared by a professional engineer or land surveyor15. Floodplain inspections occur before construction and after completion; give at least 2 working days’ notice for the initial inspection, and submit approved as-built plans if the permitted design changes16. These inspections do not establish a general countywide home-inspection program16.

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

For floodplain development permits, contact Harrison County Road & Bridge at 3800 Five Notch Road in Marshall, (903) 935-486817. For county septic permits and subdivision, mobile-home, RV or tiny-home park applications, contact Harrison County Environmental Health at 2005 Warren Drive in Marshall, (903) 935-4870, Ext. 136211. The county’s ordinary-home building-permit answer applies to unincorporated Harrison County1. Inside Marshall and Hallsville, city zoning applies34. County Environmental Health administers OSSF permitting, but Marshall’s ordinance also requires a septic permit from the city plumbing inspector; ask both offices how the approvals fit together for a Marshall address56.

Does Harrison County have zoning?

Unincorporated Harrison County has no county zoning rule setting minimum dwelling size, minimum lot size, setbacks, lot coverage or building height9. Septic, floodplain and subdivision requirements still apply10187. Marshall and Hallsville administer city zoning inside their limits34. Marshall’s Zoning Board of Adjustment handles zoning appeals, exceptions and variances, while its Planning and Zoning Commission considers zoning changes and special-use permits1920. Marshall also reviews subdivision plats inside the city and within one mile of its limits21. County Environmental Health remains the county OSSF office, and Marshall separately requires a city plumbing-inspector septic permit56.

How do septic permits work in Harrison County?

Harrison County Environmental Health requires a septic permit to construct, install, alter, extend or repair an OSSF unless an exception applies, and requires a site evaluation by a TCEQ-licensed Site Evaluator or professional engineer10. The acreage-based exception requires a tract of at least 10 acres with only a single-family dwelling, all system parts at least 100 feet from property lines, effluent disposal on the property, no nuisance or groundwater pollution, and compliance with other construction standards10. Homeowner installation has separate ownership, skill and no-sale-or-lease conditions; commercial and multifamily systems require permits and licensed installers12. County OSSF applications require planning materials, site and soil evaluation, directions, any applicable recorded affidavit and a two-year service contract; Authorization to Construct lasts 1 year, and the system must be inspected before covering22. Only 6.5% of county soils lack severe conventional-drain-field limitations, so evaluate wastewater feasibility early23. Ask Environmental Health for the current septic-permit fee: the published consumer-health schedule covers food businesses, day care and related inspections, not OSSF permits24.

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

Unincorporated Harrison County has no county zoning rule restricting RV or tiny-home occupancy or imposing a minimum dwelling size9. A subdivision, mobile-home park, RV park or tiny-home park has a county development application, and its roadway must admit the largest EMS vehicles1125. Off-grid living still requires compliance with septic rules, including a county OSSF permit unless an exception applies10. We could not confirm every acceptable off-grid sanitation arrangement; ask Environmental Health about the proposed system. Inside Marshall and Hallsville, city zoning applies34. County Environmental Health handles county OSSF approvals, and Marshall’s plumbing inspector also has a septic-permit requirement56.

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

  1. Establish the parcel’s city-limit status; Marshall and Hallsville have municipal zoning, while the county ordinary-home building-permit answer applies to unincorporated land341.
  1. Check flood status with Road & Bridge and obtain any required floodplain development permit before work or structure placement1718.
  1. Arrange the septic site evaluation and county OSSF application unless an exception applies; inside Marshall, address the plumbing inspector’s septic permit too106.
  1. Obtain a TxDOT driveway permit before state-highway right-of-way work26.
  1. Before subdividing outside city limits, resolve county plat approval or the conditional agricultural exemption78.
  1. Schedule floodplain final inspection and OSSF inspection before covering the septic system1622.

What should you check before buying land in Harrison County?

Resolve wastewater feasibility and floodplain status before buying: only 6.5% of Harrison County soils lack severe conventional-drain-field limitations, and floodplain development needs county approval2318. Dividing unincorporated land into 2 or more parts can trigger county subdivision regulations even with metes-and-bounds descriptions; covered plats require Commissioners Court approval before recording7. Preliminary plat filing costs $100 and requires submission at least 15 days before a regular court meeting27. Qualifying agricultural, farm, ranch, wildlife-management or timber divisions may be exempt if no streets or other shared/public-use areas are laid out; losing the qualifying use brings platting requirements back, and the exemption does not remove septic or floodplain rules8. The effective property-tax rate is about 1%, with a median annual bill of $1,8112829. We could not confirm private-well permit or mandatory utility-connection rules; ask the water provider or groundwater authority serving the parcel.

Watch-outs

  • The $20 residential floodplain development permit is required before covered construction begins, despite the absence of a general county permit for ordinary unincorporated homes141.
  • Marshall requires a city plumbing-inspector septic permit; ask the inspector and Harrison County Environmental Health which approvals your address needs65.
  • The published consumer-health fees are not septic-permit prices; ask Environmental Health for the current OSSF fee2411.

  • Who permits septicCounty

    OSSF permitting and administration in Harrison County, Texas, through Harrison County Environmental Health.

    • The county page identifies Harrison County Environmental Health as the permitting authority for the system in the multifamily case and states that commercial and multifamily properties require a permit.
    “THE PROPERTY OWNER MUST HAVE A PERMIT FROM HARRISON COUNTY ENVIRONMENTAL HEALTH FOR THE SYSTEM”
  • Septic permitLimited

    On-site sewage facilities, including septic systems, in Harrison County, Texas, administered locally by Harrison County Environmental Health.

    • A permit is required to construct, install, alter, extend, or repair an OSSF unless an applicable exception applies.
    • The Harrison County page states that the ten-acre rule applies only to single-family residences; commercial properties and multifamily residences require a permit and must be installed by a licensed installer.
    • The ten-acre permitting exemption requires compliance with all other planning, construction, and installation standards in 30 TAC Chapter 285.
    • The property must receive a site evaluation by a TCEQ-licensed Site Evaluator or Professional Engineer.
    • The system must serve a single-family dwelling on a tract of land of 10 acres or larger.
    • The OSSF must not cause a nuisance or pollute groundwater.
    • All parts of the OSSF must be at least 100 feet from the property line.
    • Effluent must be disposed of on the property.
    • The single-family dwelling must be the only dwelling on the tract.
