Who is licensed to look at your system
A Site Evaluator, which is a TCEQ license, evaluates the soil and the site before a system is built, and an applicant needs an Installer II, Designated Representative, engineer, sanitarian, soil scientist or geoscientist credential plus the Soil Analysis Exam. A Maintenance Provider, licensed by TCEQ as an individual person, inspects aerobic systems under the maintenance contract. Ask which of the two the visitor holds.
Septic inspection costs in Texas: our range and the evidence
The model's figure for one inspection is $110 to $455 per inspection, an estimate, not a quote. Only one Texas company, in Collin County, publishes an inspection price we could count, which is below the five needed to set a range from company prices, so the national estimate stands.
EPA's maintenance figure bundles pumping and inspection over several years, so it doesn't price one inspection.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $110 to $455 per inspection | Built from one national published range, adjusted by the Texas septic tank servicer wage ratio (0.88). Eight Texas septic companies publish a price we could count on their own websites; where five or more price the same job, the range is the middle half of their prices, and where two to four do, the estimate is widened to take them in. Coupons, specials and figures a page gives as an average are not counted. Basis: no state company sample (one counted Texas company price for this job), national estimate only. |
| Septic tank servicer pay, Texas mean | $22.64 an hour | Texas mean pay for septic tank servicers (BLS, May 2025); it doesn't set what an inspection costs. |
| EPA's national maintenance fee, every three to five years | $250 to $500 | A national figure covering several years of upkeep, not a single Texas inspection. |
Estimated range. Built from national published ranges (1 source), adjusted by Texas's septic tank servicer wage ratio to the US (0.88, BLS May 2025). Not a quote. Eight Texas septic companies publish a price we could count on their own websites; where five or more price the same job, the range is the middle half of their prices, and where two to four do, the estimate is widened to take them in. Coupons, specials and figures a page gives as an average are not counted. Only one Texas company publishes a price we could count for this job, so the range is our national estimate alone. Full method. Prices as of Oct 23, 2026.
What the contract visit covers on an aerobic unit
The provider tags the system when the contract starts, punches or marks the tag at each visit, inspects every component and tests the system as 30 TAC 285.91(4) requires. Reports go to the permitting authority and to you within 14 days of each test. Some counties charge a yearly fee. Bell County's district lists $20 per contract year for a maintenance inspection or contract verification, and McLennan's $20 annual fee is sent in by the provider, or by the owner who maintains the system personally. A report that shows a malfunction goes to the local permitting authority, which must investigate a complaint within 30 days.
Inspection findings that can't wait
- Sewage is surfacing over the tank or field, or backing up indoors.
- A routine check on a system that drains normally and has no alarm.
Before the inspector comes
- Find out whether the system is conventional or aerobic.
- Ask the company which TCEQ license the person holds.
- Ask the county permitting office whether its order sets an inspection schedule.
- Get the report in writing.
Does an inspection need a permit?
TCEQ's pages list constructing, altering, repairing, extending and operating a system as permit work, and looking at an existing tank isn't on that list. A repair that follows the look is, and it goes through the county or the other authorized agent for your address.
Questions people ask
How often is a Texas aerobic system inspected?
At every visit under the maintenance contract, and the provider reports at least once every four months. Every six months is allowed where electronic monitoring or automatic alerts are used, and each report is due within 14 days of the test.
How much does a Texas septic inspection cost?
$110 to $455 per inspection in our model; one Texas company's price is all we counted. That's a national estimate adjusted by the Texas wage ratio, an estimate and not a quote. Ask for the company's price in writing.
Who is licensed to evaluate a septic site in Texas?
A TCEQ Site Evaluator, or a Professional Engineer. Site evaluators complete an approved course and pass the Soil Analysis Exam, and the application fee is $111. TCEQ's licensing staff take calls at (512) 239-6133.
