If your Heath home runs on a septic or aerobic system, the buyer's inspector is not the only one who has to look at it before closing. The City of Heath requires its own compliance inspection of the on-site sewage facility before the title can change hands. That makes the system a city-permitted asset with its own paper trail, and the paper trail goes to the buyer along with the house.
For sellers, the system's history is something to put together before listing. It doesn't belong in the last week before closing.
The rule, in the city's own words
Chapter 53 of the Heath Code of Ordinances covers on-site sewage facilities, which the state shortens to OSSF. Section 53.02, subsection I, states the requirement plainly:
"A compliance inspection by the City Health Officer or Building Official shall be required prior to transfer of title ownership on all property within the city. A fee, established by the City Council, shall be charged for the inspection. In lieu of a city inspection, a certificate of inspection by a registered sanitarian authorized to perform the inspections may be accepted by the Building Official."
That gives a seller two ways to get it done. The city can do the inspection, or a registered sanitarian can provide a certificate that the Building Official may accept in its place. Either way, the inspection or the accepted certificate has to come before title transfers. You can read the full chapter in Heath's online code library.
The Building Official is the city's designated enforcement representative for these rules, and that person has to be approved and certified by the Texas Commission on Environmental Quality. In practice, a septic home's closing runs partly through Heath's Building & Inspections department.
Grandfathered systems are included
Many Heath homeowners assume an older system is exempt from current rules. For most of Chapter 53, that's true. Section 53.03 says facilities already in place when the chapter took effect don't have to meet its provisions, with two exceptions: the rules on public nuisances and the transfer-of-title provision.
So a system can be grandfathered on design and still need the compliance inspection at sale. One small wrinkle for anyone reading the code closely: Section 53.03 points to the transfer provision as subsection H, but in the current text the transfer requirement is subsection I. Subsection H covers the city's authority to decline plans. The online code host also warns that its text may not reflect the most recent legislation. Both are good reasons to confirm the current process directly with the city.
Why so many Heath systems are aerobic
Heath's soil explains why its systems tend to need ongoing upkeep. Under Section 53.02, any system with a pump has to include an aerobic treatment unit, low-pressure dosing included. The code gives the reason as protecting the public from surfacing waste "due to the soil conditions found in the City of Heath." The city can also reject a system plan it believes won't work, even one designed to minimum standards.
Heavy clay soil gives a sense of what the code is guarding against. The USDA's official description of the Houston Black soil series calls it "very slowly permeable," with 40 to 60 percent clay, cracking in dry seasons and high shrink-swell potential. That's a description of the soil type in general, not of any one lot. What a particular property sits on takes a site evaluation and the NRCS Web Soil Survey.
An aerobic system isn't a tank you can forget about. It comes with a contract, a service schedule and recorded documents, and all of those become part of the sale.
The paperwork that goes to the buyer
Heath's OSSF permit package includes a Rockwall County affidavit, the "Certification of OSSF Requiring Maintenance," which is filed in the county deed records. It says the system must be covered by a continuous service agreement for its first two years. After that, the owner of an aerobic system on a single-family home has to get a maintenance contract within 30 days. It also says that when the property is sold, the OSSF permit transfers to the buyer.
The ongoing requirement comes from TCEQ, which describes maintenance providers reporting at least every four months, or every six months for systems with qualifying electronic monitoring. Local rules can be stricter than the state minimum. TCEQ's maintenance guidance also covers pumping. Conventional tanks are generally pumped every three to five years, while aerobic units are pumped based on sludge depth and the manufacturer's guidance.
For a sense of scale, one septic provider that serves Heath advertises a $250 annual compliance contract with three inspections and reports to the authority and the homeowner. Repairs, chlorine and pumping cost extra. That's one company's posted price, not a market average, so buyers should get their own quotes.
A seller with a current contract, recent service reports and the permit file can show a buyer three things: the system has been maintained, the reporting is up to date, and the transfer should be routine. A seller without those records will be finding them while the closing clock runs.
Older small lots have their own rules
Section 53.09 covers a particular group of properties: lots under one acre that were platted before January 1, 1988. On those lots, a home is limited to three bedrooms if the lot is under 15,000 square feet, and to four bedrooms if it's over 15,000 square feet but under half an acre. No structure or impervious covering can sit over a septic tank. A sewer lateral has to run from the house to the street or property line, valved and capped so the septic system can be shut off once city service arrives.
The provision buyers most need to understand is subsection G. Once a city sewer lateral reaches any of the owner's property lines, the owner has three months to connect. If the owner doesn't connect, the city may connect the home itself and place a lien on the property for the cost.
On these lots, a future sewer connection is something the code anticipates, and a buyer should ask whether city service is nearby. These rules apply only to that platted category. For new systems, Heath won't issue an OSSF permit for property under one acre, and systems installed before the chapter was adopted are grandfathered on acreage.
What the disclosure has to say
Texas Property Code Section 5.008 requires sellers of covered residential property to give buyers a written disclosure. It's based on what the seller knows, and it doesn't replace inspections. The current TREC Seller's Disclosure Notice, effective May 28, 2026, asks whether the property has a septic system or public sewer and whether the seller knows of defects or malfunctions in plumbing, sewers or septics.
Timing matters. If the buyer receives the disclosure after signing the contract, the statute gives them up to seven days after receiving it to terminate. A late disclosure on a septic home reopens a buyer's option to walk away.
Texas REALTORS publishes a separate form, TXR 1407, for OSSF details: drain-field location, installer and age, maintenance contract, pumping history, known defects and planning materials. It isn't an inspection or a warranty. The association reported an update to the form in January 2026. Filling it out is easy for a seller who already has the maintenance records.
What the city charges
Heath's fee schedule for fiscal year 2026-2027 took effect October 1, 2026. These are its OSSF line items:
| Heath OSSF fee, FY2026-27 | Amount |
|---|---|
| New or replacement OSSF | $750 |
| Modification to an existing system | $400 |
| Extraordinary inspection after a third failed inspection | $100 each |
| After-hours or weekend inspection | $80 per hour, two-hour minimum |
The schedule doesn't list a separate fee for the pre-sale compliance inspection, even though the code says the City Council sets one. The OSSF application PDF posted on the city's site still carries an "UPDATED 10/07/2010" stamp with older, lower fees, so the current schedule is the one to use. To confirm the transfer inspection fee and how to schedule one, the city lists Building Official Leisa Price at 972-961-4891 or [email protected].
The fee schedule also shows why a failed inspection costs more than one fee. If the system needs a new unit, the replacement permit alone is $750, plus contractor work and whatever schedule slip comes with it.
A seller's order of operations
- Before listing, call Heath Building & Inspections to confirm the current transfer inspection process and fee, and ask whether a registered sanitarian's certificate would be accepted for your property.
- Pull the system's file. That means the OSSF permit, the recorded maintenance certification if the system is aerobic, the current maintenance contract and the last several service reports.
- Fix the easy things early. A missed service visit or a lapsed contract is easier to deal with before a buyer's inspector finds it.
- Complete the TREC Seller's Disclosure Notice before the contract is signed, and consider attaching the TXR 1407 OSSF information form.
- If your lot is under one acre and was platted before 1988, find out whether a city sewer lateral is at or near your property line, since that triggers the three-month connection rule.
- Schedule the compliance inspection early enough that a failed result leaves time for repair permits before the closing date.
This is general information, not legal advice. Your title company, a licensed septic professional and the City of Heath are the right sources for your specific property.
