A Tom Green County building permit is not issued by the county. Like most Texas counties it has no adopted residential building code and no building inspection program for unincorporated areas. What applies are the environmental and land records that govern rural construction: on-site sewage facility permitting, floodplain development, subdivision platting, addressing, and county road access — and we file and track all of them for you.

That is a statutory limit rather than a local choice. Texas counties may adopt narrow authority over new commercial, public-accessible, and multifamily buildings under Local Government Code ch. 233, but they generally cannot regulate residential construction, inspect it, or issue a residential certificate of occupancy outside city limits.

Tom Green County sits in the Concho Valley in West Central Texas with San Angelo as the seat. A large share of the county population lives inside San Angelo, which runs a conventional municipal building department — so the first question on any project is which side of the city limit the parcel falls on.

Covers unincorporated Tom Green County. San Angelo, Christoval, Wall, and Grape Creek-area communities — confirm whether the parcel is inside a city limit or an ETJ before assuming county rules apply, and note that Goodfellow Air Force Base is federal land outside both systems.

📍

No county building permit is not no requirements. A rural Tom Green County build still needs an OSSF permit before the septic goes in, floodplain compliance if the parcel touches a mapped hazard area, a plat if land is being divided, and an address before utilities connect. Confirm current requirements directly with the county before relying on any summary.

What requires a county permit in Tom Green County?

The question in unincorporated Tom Green County is not which building permit you need. It is which environmental and land records your project triggers, and whether the parcel is genuinely outside San Angelo city limits, its extraterritorial jurisdiction, and Goodfellow Air Force Base.

On-site sewage carries the clearest statewide requirement. 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.

Still required

  • On-site sewage facility permit — required statewide
  • 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
  • Municipal ETJ requirements where San Angelo’s extraterritorial jurisdiction reaches the parcel

Not required by the county

  • County building permit — not issued
  • County building code compliance — none adopted
  • County construction inspections across the trades
  • County certificate of occupancy
⚠️ The absence of a building code does not suspend state law. TDLR retains electrical and accessibility enforcement authority in unincorporated areas, and the State Fire Marshal’s Office holds primary fire code jurisdiction there. Lenders and insurers will look for documentation the county never created.

Tom Green County building department: who handles permitting

Tom Green County administers on-site sewage permitting through environmental health as the local authorized agent, with floodplain administration, subdivision platting, and road access handled through county offices and Commissioners Court at San Angelo.

Confirm requirements with the county directly. Tom Green publishes less permitting detail online than the larger Texas counties, and a phone call resolves in minutes what desk research leaves ambiguous.

Tom Green County permits: record types and what each covers

The permit-type question works differently in a Texas county. Tom Green County has no adopted building code for unincorporated areas and issues no residential building permits, so there is no record-type matrix of the kind San Angelo maintains. What exists is a set of environmental and land records, each administered by a different office.

Solar permits in Tom Green County

In unincorporated Tom Green 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 San Angelo city limits the picture changes completely: the city permits solar like any other municipality. The jurisdiction question is the first question.

Roofing permits in Tom Green County

A residential roof covering replacement in unincorporated Tom Green 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.

Tom Green County sits in the Concho Valley at roughly 105 to 115 mph ultimate design wind speed under the codes regional cities adopt, far from the designated catastrophe area and outside any TDI windstorm requirement. Hail is the governing risk, and West Central Texas storm cells can drop very large hail in concentrated areas.

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.

Record types, fees, and administering offices are set by Tom Green County and change without notice, and any ch. 233 commercial authority depends on what Commissioners Court has adopted. San Angelo and the smaller municipalities permit independently, and Goodfellow Air Force Base is federal property. Confirm jurisdiction before relying on any of this.

Tom Green County permit cost and fees

Tom Green County charges no building permit fees because it issues no building permits. Costs attach to OSSF permitting and its licensed site evaluation, floodplain permitting where applicable, platting, and road access.

The site evaluation is the line most often left out of an early budget. Concho Valley soils and shallow bedrock in places determine whether a conventional drain field works or an aerobic treatment system is required.

Tom Green County trade permits

There is no county trade permit program in unincorporated Tom Green 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.

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 environmental health 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 or on base

San Angelo permits and inspects normally. Goodfellow Air Force Base runs its own authorities entirely.

🧢 With no county trade inspection, nothing independently verifies the work and no permit history exists for a future buyer, appraiser, or insurer. Keeping your own documentation of licensed contractors and engineered plans is worth doing even though nobody requires it.

Tom Green County permit application: how to apply step by step

1. Confirm the jurisdiction — all three

Check whether the property is unincorporated, inside San Angelo or another municipality, or on Goodfellow Air Force Base land.

2. Call the county before designing

Tom Green publishes limited permitting detail online. Confirm current OSSF, floodplain, and platting requirements with county offices directly.

3. Engage a licensed site evaluator

Soil testing on the specific parcel is required for OSSF permitting and determines system type and house siting.

4. Apply for the OSSF permit

File with county environmental health. Aerobic systems carry a continuous maintenance contract and a recorded affidavit.

5. Handle floodplain, plat, and access

Determine flood hazard status, work platting through Commissioners Court if dividing land, obtain a 911 address, and permit driveway access.

6. Build to code voluntarily and document it

With no county code or inspection, build to a recognised code edition anyway and keep records of licensed trades and engineered plans.

Inspections in Tom Green County

Tom Green County performs no 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 permitting process, and aerobic and surface application systems carry continuing maintenance and inspection obligations under state rules after the permit issues.

Private third-party inspection is worth considering on a new build. In a county that generates no construction record, it is the only independent documentation a lender, insurer, or future buyer will have.

Frequently asked questions

Who issues building permits in Tom Green County?

No one, for general residential construction in unincorporated areas — Tom Green County has no adopted residential building code and no building inspection program. The records that do apply are administered separately: on-site sewage through Tom Green County Environmental Health, floodplain development through the county floodplain administrator, plats through Commissioners Court, and road access through the precincts. Inside San Angelo city limits, the city permits normally.

How do I get a permit in Tom Green 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 Tom Green County?

Texas has no statewide building code, and Tom Green 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 Tom Green County issue building permits?

No, not for general residential construction in unincorporated areas. The county has no adopted residential building code and no building inspection program, which is the standard Texas county position. On-site sewage permitting, floodplain requirements, subdivision platting, addressing, and county road access are the records that do apply. Confirm current requirements directly with the county before relying on any summary.

What about property inside San Angelo?

Then the county guidance does not apply. San Angelo runs a conventional municipal building department with plan review, trade permits, and inspections, and carries the medical, retail, and institutional construction for a wide surrounding area. It also exercises extraterritorial jurisdiction beyond its limits, so an unincorporated parcel near the city may still carry municipal obligations. Confirm the parcel against current city limits and ETJ.

What about construction on Goodfellow Air Force Base?

Neither county nor city permitting reaches it. Goodfellow Air Force Base is federal property with its own authorities and contracting processes, so construction there runs entirely outside the Tom Green County and City of San Angelo systems. That makes this a three-jurisdiction county — unincorporated, municipal, and federal — and establishing which one holds a parcel is the first question on any project near the base.

Do I need a permit to install solar panels in Tom Green County?

Yes. Photovoltaic installations in Tom Green 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 Tom Green County?

Yes, in most cases. A roof covering replacement requires a permit in most Texas municipalities including Tom Green 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 Tom Green County?

In a Texas county it is the difference between no county jurisdiction and possible county jurisdiction. Residential construction in unincorporated Tom Green 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 Tom Green County?

Not in unincorporated Tom Green 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 Tom Green County?

Because Tom Green 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 Tom Green County permit types online?

Largely no. Tom Green County administers its records through county offices at San Angelo rather than a unified permitting portal, and it publishes less permitting detail online than the larger Texas counties. Expect a manual, phone-and-counter process, and treat direct confirmation with the county as a necessary step rather than an optional one.
