Building permits, zoning and septic rules in Gregg County, Texas

#74 of 254 in Texas

Unincorporated Gregg County, Texas does not require a building permit or inspection for a house, because the county's own services listing has no building or inspection department1. There is also no countywide zoning ordinance, so the county sets no rule on setbacks, minimum home size, or living in an RV while you build23. The permit almost every rural buyer in Gregg County does need is for the septic system, handled by the Gregg County Health Department4.

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

Gregg County, Texas lists no building or inspection department among its official county services, and the county's services directory only lists Septic Systems under the Health Department for land-use permitting1. Texas gives counties only limited authority to require building permits or codes outside incorporated cities: fire-code permitting for certain large buildings applies only in counties over 250,000 people (or adjacent to one), and any residential building-code standard a county adopts applies only to new construction after September 1, 2009 and only if the commissioners court passes a resolution10. Whether Gregg County has adopted any such resolution was not confirmed on the county's official site, so if you plan to build, ask the County Judge's office directly before you assume no inspection will ever apply.

Who handles septic and permits in Gregg County, and how do you reach them?

There is no separate building department to call in unincorporated Gregg County; the office a rural land buyer needs is the Gregg County Health Department's Septic Systems (OSSF) program, reached at (903) 237-26284. That office reviews and approves on-site sewage facility applications, issues the Permit to Operate after inspection, and posts the application, checklist and site-evaluation forms on its page46. If your build involves a state highway driveway, that permit comes from the local TxDOT district office instead, using Form 105811.

Does Gregg County have zoning?

Gregg County has no countywide zoning ordinance2. Texas law only lets counties zone in a handful of narrowly defined situations — Padre Island in Cameron or Willacy County, the Amistad Recreation Area, certain lakes and a few other named places — none of which include Gregg County12. Because the county has no zoning authority here, it sets no minimum home size, no setbacks, no lot coverage limits and no zoning districts, and it does not restrict accessory dwellings, RVs, tiny homes, manufactured homes or temporary camping on unincorporated land3. That is a statement about county zoning only: it does not remove septic, floodplain or state-highway-access requirements that apply separately.

How do septic permits work in Gregg County?

Every on-site sewage facility (OSSF) in Texas needs a permit before it is built, altered, extended or repaired, and the Gregg County Health Department is the local authorized agent that issues them135. For a conventional system, the county requires at least a half-acre lot with community water or a full acre with a private well, though lots platted before January 1, 1988 that fall short can be reviewed case by case7. A professionally designed system costs $350 to permit for a single-family home ($450 for commercial), and the applicant must hire a Registered Sanitarian or Professional Engineer to evaluate the site and design the system before GCHD will authorize construction814. Only about 5.3% of Gregg County's soils lack severe limitations for a conventional drain field, so most rural lots here should budget for an engineered or aerobic system rather than assume a standard gravity system will pass15. The system cannot legally be used until GCHD inspects and approves it, and a state 10-acre exemption from permitting exists only if a licensed site evaluator confirms the tract, effluent and setbacks all meet the specific conditions, including keeping the OSSF at least 100 feet from every property line613.

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

Gregg County's lack of zoning authority means the county itself does not restrict RV, manufactured home or tiny-home occupancy on unincorporated land3. That does not exempt you from Texas's septic rules: any wastewater from an RV, tiny home or off-grid dwelling still has to go through an approved OSSF, and a holding tank is only allowed where other sewage disposal is not feasible, must have a high-level alarm at 75% capacity, and needs a pumping contract on file before installation16. Confirm with the Gregg County Health Department how your specific setup will be permitted before you move a camper or tiny home onto raw land4.

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

  1. Confirm your parcel is in unincorporated Gregg County rather than inside Longview, Kilgore or another city, since municipal codes are separate from the county rules described here1.
  2. Know that no county building permit is required for the residence itself in unincorporated Gregg County1.
  3. Apply for your septic (OSSF) permit through the Gregg County Health Department before you finalize a house site, since the approved septic layout constrains where the house and driveway can sit414.
  4. Hire a Registered Sanitarian or Professional Engineer for the required site evaluation and system design, and submit the checklist and plans to GCHD for authorization before construction begins14.
  5. If your driveway will connect to a state highway, contact the local TxDOT district office and file Form 1058 before building it11.
  6. Schedule your OSSF installation inspection with at least one working day's notice, and do not cover the system until GCHD approves it14.

What to check before you buy land in Gregg County

Budget for septic first: with only 5.3% of county soils free of severe limitations for a conventional drain field, get a site evaluation before you commit to a parcel15. Farmland in Gregg County has recently averaged about $6,992 an acre and a typical home is valued around $225,144, so weigh raw-land and septic costs together1718. The county sees severe drought in roughly 14.9% of years, which matters for a private well or pond19, and it sits about 29 miles from the nearest metro area20. Property taxes run about 1.2% of value21, with a median bill near $2,27122. Floodplain development rules and a countywide certificate-of-occupancy requirement were not confirmed on the county's official site as of this review, so ask the County Judge's office or Emergency Management directly if your parcel is anywhere near a floodplain.

Watch-outs

  • Whether Gregg County has adopted any residential building-code resolution under state law was not confirmed on the county's official site; call the County Judge's office before you assume no inspection will ever apply10.
  • Gregg County's official services listing names no floodplain department alongside its other services1, so floodplain development rules for unincorporated Gregg County were not confirmable; ask Emergency Management or the County Judge's office if your parcel is near a floodplain.
  • The owner-builder exemption in Texas law only excuses you from a penalty for failing to give construction-inspection notice under Chapter 233; it does not exempt you from septic permitting or any other requirement, and it only matters where the county enforces those inspection provisions in the first place9.
