Gregg County has no identified general building permit department. No county-issued general building permit requirement has been identified for unincorporated Gregg County from official county materials, which places it firmly in the standard Texas county pattern — no residential building code, no inspection program, no residential certificate of occupancy.
What is clearly established is septic. For on-site sewage facilities, the Gregg County Health Department at (903) 237-2628 administers the published septic-system permit process as the local authorized agent under state rules.
For general building construction, verify directly with the county or your city before assuming a county-issued building permit is available. Gregg is a small, heavily urbanised East Texas county built around Longview and Kilgore, so a large share of parcels sit inside a city limit where a full municipal process applies.
Covers unincorporated Gregg County. Longview, Kilgore, White Oak, Gladewater, and Easton permit their own territory — and because Gregg is one of the smaller Texas counties by area with two substantial cities in it, confirming city limits is the essential first step.
Confirm the property is actually unincorporated. Gregg County is compact and heavily urbanised around Longview and Kilgore, so a parcel that feels rural may well sit inside a city limit or ETJ where a full municipal building permit process applies. That single check determines whether any of this guidance is relevant.
What requires a county permit in Gregg County?
The question in unincorporated Gregg County is not which building permit you need, because no county general building permit office has been identified. It is which environmental and land records your project triggers, and whether the parcel is genuinely outside Longview, Kilgore, and the other municipalities.
On-site sewage is the record with clear published process. Texas requires a permit for any OSSF under Texas Health and Safety Code Chapter 366 and TCEQ rules at 30 TAC 285, administered locally by an authorized agent — here, the county health department.
Still required
- On-site sewage facility permit — through the Gregg County Health Department
- Licensed site evaluation as part of the OSSF application
- Continuous maintenance contract on aerobic and surface application systems
- Floodplain development where the parcel touches a mapped hazard area
- Subdivision plat when land is divided
- 911 address assignment for new structures
- Driveway or culvert access onto a county road
Not identified at county level
- County general building permit — no county department identified
- County building code compliance — none adopted
- County construction inspections across the trades
- County certificate of occupancy
Gregg County building department: who handles permitting
The Gregg County Health Department administers on-site sewage facility permitting as the local authorized agent and can be reached at (903) 237-2628. Floodplain administration, subdivision platting, and road access sit with county offices and Commissioners Court in Longview.
For anything touching general building construction, the practical route is to confirm the jurisdiction first and then contact either the relevant city building department or the county directly — rather than assuming a county process exists.
| Detail | Information |
|---|---|
| General building permits | No county building department identified in official county materials |
| OSSF / septic | Gregg County Health Department — (903) 237-2628 |
| Governing rules | Tex. Health & Safety Code ch. 366 and TCEQ rules at 30 TAC 285 |
| County seat | Longview |
| Other principal city | Kilgore |
| Floodplain, plats, roads | Gregg County offices and Commissioners Court |
| State oversight | TDLR for electrical and accessibility; State Fire Marshal for fire code |
| Inside city limits | Longview, Kilgore, White Oak, Gladewater, Easton |
Start with the septic call. The health department at (903) 237-2628 is the clearest published county contact for construction-related permitting, and the OSSF process will constrain house siting regardless of what else applies.
Gregg County permits: record types and what each covers
The permit-type question works differently in a Texas county, and Gregg is at the sparse end. No county general building permit office has been identified from official county materials, so there is no record-type matrix of the municipal kind. What exists is on-site sewage permitting through the health department plus the standard land records.
What Gregg County actually issues
| Record | What triggers it | Who administers it | Notes |
|---|---|---|---|
| OSSF permit to construct | Installing, altering, repairing, or extending an on-site sewage facility where no public sewer is available | Gregg County Health Department | Required statewide; soil evaluation by a licensed site evaluator is part of the application |
| OSSF license to operate | Issued after the permit to construct requirements are met and the system passes inspection | Gregg County Health Department | Also triggered on transfer of ownership of an existing system |
| Floodplain development permit | Placing fill, setting a structure, or developing in or near a mapped special flood hazard area | County floodplain administrator | Substantial improvement and substantial damage rules attach to existing structures |
| Subdivision plat | Dividing land in the unincorporated county | Commissioners Court and county engineering | Road, drainage, and access standards apply |
| 911 address assignment | New structures and new access points needing an address | County addressing / emergency management | Usually a prerequisite for utility service |
| Right-of-way and driveway culvert | New or modified access onto a county road | County road and bridge / precinct | Culvert sizing set by drainage conditions |
| Water well registration | Drilling a water well | the applicable groundwater conservation district | Groundwater districts operate independently of the county |
| Ch. 233 commercial / multifamily | New commercial, public-accessible, or multifamily buildings, and substantial improvements, where the county has adopted the authority | Commissioners Court | Scope is set by county order; confirm adoption before assuming it applies |
County reaches this
- On-site sewage facilities, everywhere in the state
- Floodplain development and substantial improvement
- Subdivision of land and county road access
- Addressing, and fire code where separately adopted
County generally does not
- Issue residential building permits in unincorporated areas
- Conduct residential construction inspections
- Issue a residential certificate of occupancy
- Enforce a residential building code absent a county order adopting one
Solar permits in Gregg County
In unincorporated Gregg County there is generally no county building permit for a residential rooftop or ground-mount photovoltaic system, because the county does not regulate residential construction. That is a jurisdictional fact rather than a green light: the electrical work still has to be performed by a TDLR-licensed electrician to code, and the utility still governs interconnection.
Utility interconnection is the real gate. The interconnecting utility — the wires company in deregulated territory, or the electric cooperative serving the parcel in much of rural East Texas — runs its own application, engineering review, and Permission to Operate process, and it is not waived by the absence of a county permit.
Under Tex. Prop. Code §202.010 a property owners' association cannot prohibit a solar energy device outright, and any dedicatory provision that does is void — but the statute preserves the association's right to require prior architectural approval and to impose placement and appearance conditions. Approval cannot be unreasonably withheld.
Inside Longview city limits the picture changes completely: the city permits solar like any other municipality. The jurisdiction question is the first question.
Roofing permits in Gregg County
A residential roof covering replacement in unincorporated Gregg County generally does not require a county permit, for the same reason: Texas counties have no general authority over residential construction outside city limits.
Two things still apply. If the structure sits in a mapped special flood hazard area, the county floodplain ordinance can reach the work through substantial improvement rules — and cumulative improvement value is what triggers them, so a reroof after other recent work can cross the threshold on its own. And commercial or multifamily buildings can fall under the county's Ch. 233 authority where it has been adopted.
Texas has no statewide product approval system and no central listing to check a roofing product against. Hail is the governing risk across East Texas, and impact-resistant Class 3 and Class 4 shingles carry insurance premium credits from most carriers. Under Tex. Prop. Code §202.011 a property owners' association cannot prohibit wind or hail resistant shingles, or shingles that improve energy efficiency.
Gregg County sits in the East Texas Piney Woods at roughly 105 mph ultimate design wind speed under the codes regional cities adopt, with no coastal exposure and no TDI windstorm requirement. Hail and falling timber during storm events drive claims here more than sustained wind does.
Texas has no statewide building code and no statewide general contractor license. In the unincorporated county the practical compliance surface is the trades — TDLR for electrical and mechanical, the TSBPE for plumbing — plus the county's environmental and floodplain records, rather than a building department.
Gregg County permit cost and fees
Gregg County charges no general building permit fees because no county building permit department has been identified. Costs attach to OSSF permitting and its site evaluation, floodplain permitting where applicable, platting, and road access.
The site evaluation and system design are the professional costs that matter most. East Texas soils vary considerably across short distances, and the result determines whether a conventional drain field works or an aerobic system is required.
| Fee component | How it works |
|---|---|
| General building permit | None identified at county level |
| OSSF permit | Health department fee plus licensed site evaluation and design |
| Aerobic system | Adds a continuous maintenance contract and a recorded affidavit |
| Floodplain development | County fee where applicable |
| Subdivision plat | Filing and review fees, plus survey and engineering |
| Road access / culvert | County fee plus materials and installation |

Gregg County trade permits
There is no county trade permit program in unincorporated Gregg County. Electrical, plumbing, and mechanical work is neither permitted nor inspected by the county. On-site sewage is the exception and it is permitted and inspected through the health department.
Electrical
No county permit or inspection. A TDLR-licensed electrician remains the standard, and TDLR retains enforcement authority in unincorporated areas.
Plumbing
No county permit for interior plumbing. The septic system is permitted through the county health department with a licensed design behind it.
Mechanical / HVAC
No county permit or inspection. TDLR licensure applies to the contractor regardless of whether a permit exists.
Inside a city limit
Longview, Kilgore, White Oak, and Gladewater permit and inspect trades normally. Jurisdiction determines everything.
Gregg County permit application: how to apply step by step
Gregg County is compact and urbanised. Check against Longview, Kilgore, White Oak, Gladewater, and Easton, and their ETJs.
For general building construction, confirm with the county or your city rather than assuming a county-issued permit is or is not available.
Contact the Gregg County Health Department at (903) 237-2628 and use the published septic-system permit process. Engage a licensed site evaluator.
Determine whether the parcel touches a mapped special flood hazard area before designing.
Work subdivision requirements through Commissioners Court if dividing land, obtain a 911 address, and permit driveway access onto county roads.
With no county code or inspection, build to a recognised code edition anyway and keep records of licensed trades and engineered plans.
Inspections in Gregg County
Gregg County does not conduct residential construction inspections in unincorporated areas. There is no foundation, framing, rough-in, or final building inspection, and no county certificate of occupancy.
On-site sewage installations are inspected as part of the health department permitting process, and aerobic and surface application systems carry continuing maintenance and inspection obligations under state rules.
Private third-party inspection is worth considering on a new build. In a county that performs no building inspection, it is the only independent construction record a lender, insurer, or future buyer will have.

Frequently asked questions
Who issues building permits in Gregg County?
No one, for general residential construction in unincorporated areas — Gregg County has no adopted residential building code and no building inspection program. The records that do apply are administered separately: on-site sewage through Gregg County Health Department, floodplain development through the county floodplain administrator, plats through Commissioners Court, and road access through the precincts. Inside Longview city limits, the city permits normally.
How do I get a permit in Gregg County?
Start by confirming the parcel is actually unincorporated, because that single question changes everything and a mailing address will not answer it. If it is, work the records the county does issue rather than looking for a building permit: septic first, since it constrains siting and carries the longest lead time, then floodplain, plat, addressing, and road access as the project triggers them.
What codes apply in Gregg County?
Texas has no statewide building code, and Gregg County has not adopted one for unincorporated areas, so no building code is enforced there. State rules still govern on-site sewage facilities, and the county’s floodplain ordinance governs development in mapped flood hazard areas. Trade work remains subject to state licensing through TDLR and the TSBPE. Inside city limits, the municipality’s adopted codes apply in full.
Does Gregg County issue building permits?
No county general building permit requirement has been identified for unincorporated Gregg County from official county materials, and no county general building-permit office was identified. For general building construction, verify directly with the county or your city before assuming a county-issued building permit is available. What is clearly established is on-site sewage permitting through the Gregg County Health Department.
Who handles septic permits in Gregg County?
The Gregg County Health Department, reachable at (903) 237-2628, which administers the published septic-system permit process as the local authorized agent under Texas Health and Safety Code Chapter 366 and TCEQ rules at 30 TAC 285. A licensed site evaluator, registered sanitarian, or professional engineer prepares the design based on soil conditions on your parcel, and aerobic systems carry a continuous maintenance contract plus a deed-recorded affidavit.
What about property inside Longview or Kilgore?
Then the county guidance does not apply. Longview is the county seat and Kilgore the other principal city, and both permit and inspect construction inside their limits as normal municipal building departments — as do White Oak, Gladewater, and Easton. Gregg is one of the smaller Texas counties by area with a high share of its population inside city limits, so this check matters more here than in a large rural county.
Do I need a permit to install solar panels in Gregg County?
Yes. Photovoltaic installations in Gregg County are permitted under a dedicated solar record type reviewed on both a structural and an electrical track. Solar thermal — passive water and pool heating — is a separate record. Under Tex. Prop. Code §202.010 a homeowners' association cannot ban a solar energy device outright, but it may still require prior architectural approval and impose reasonable placement conditions, so run the HOA submittal alongside the permit. Since September 1, 2025, Tex. Local Gov't Code §247.0025 (SB 1202) also permits third-party plan review and inspection of home backup power installations — generators and energy storage for one- and two-family dwellings at 600 volts or less — in place of jurisdiction review. Utility interconnection and Permission to Operate still run in parallel.
Does a roof replacement require a permit in Gregg County?
Yes, in most cases. A roof covering replacement requires a permit in most Texas municipalities including Gregg County, though minor repairs can fall below the local threshold. Texas has no statewide product approval system and no central product listing, so compliance runs against the locally adopted code edition and its local amendments. Hail rather than wind is the governing risk inland, and Tex. Prop. Code §202.011 bars an HOA from prohibiting wind or hail resistant shingles.
What is the difference between a residential and a commercial permit in Gregg County?
In a Texas county it is the difference between no county jurisdiction and possible county jurisdiction. Residential construction in unincorporated Gregg County is largely outside county authority. New commercial, public-accessible, and multifamily buildings, plus substantial improvements, are the categories Local Government Code ch. 233 lets a county reach — but only where Commissioners Court has adopted that authority, so confirm it rather than assuming.
Do trade permits need to be pulled separately in Gregg County?
Not in unincorporated Gregg County — there is no county trade permit program and no county trade inspection. Electrical, plumbing, and mechanical work should still be performed by contractors licensed through TDLR and the TSBPE, and the septic connection is permitted and inspected separately. Inside city limits, trade permits work normally.
What happens if I file under the wrong permit type in Gregg County?
Because Gregg County does not run a building permit program, the more common failure is filing nothing at all — assuming that no building permit means no requirements, and missing the septic, floodplain, plat, or addressing record the project actually triggered. Those are enforced, and unwinding them after construction is materially harder than filing them in order.
Can I apply for all Gregg County permit types online?
Largely no. Gregg County administers septic permitting through the health department and other records through county offices in Longview rather than a unified permitting portal, and it publishes less permitting detail online than the larger Texas counties. Expect a phone-and-counter process, and treat direct confirmation with the county or the relevant city as a necessary step.
