Kaufman County Septic Permits (OSSF): The Actual Process

What goes in a Kaufman County OSSF application package?

A complete package has four parts under 30 TAC 285.3(b): the county's application form, the planning materials (the design), the site evaluation, and the fee. Aerobic systems add a maintenance contract and a recorded certificate. The county form says it plainly at the top: incomplete applications will not be accepted for submission.^source

The form itself is short, but it asks for things people don't have on hand. You need the owner's driver's license or ID number, the Property ID from the Kaufman County Appraisal District, the subdivision, phase, and lot if there is one, the house type, square footage, and bedroom and bathroom counts, and the installer's name and TCEQ OSSF license number. Bedrooms matter most, because they set the design flow. Our septic system size guide shows the math.^source

If the parcel already has a septic system and you're adding a second one, the county wants a new address letter from Kaufman County 911/GIS attached, and the form repeats the rule that each septic needs one acre of usable space and its own address. That's the Kaufman County 1-acre rule showing up on paper.^source

Who signs the septic permit application, and what are you agreeing to?

The property owner signs page one, and that signature does two things. It certifies that everything on the form is true and that you own the land or have authority to build on it. It also gives the county's designated representative permission to enter the property to inspect. Don't sign a blank form and hand it to someone.

An agent can apply instead, but only a specific kind of agent. Page two asks for the agent's title, address, date of birth, and ID, then requires them to initial one of three boxes: a partner of an owner partnership, an officer of an owner corporation or LLC, or someone whose job gives them authority to set the entity's policy on this matter. The form says that if none apply, you're not the right person to be signing.

The design is the part homeowners can't do themselves. Statewide, 30 TAC 285.5 lets owners or installers prepare planning materials for some standard systems. Kaufman County's TCEQ-approved order is stricter: only a registered professional engineer or registered professional sanitarian with a current site evaluator certification may perform site evaluations and complete OSSF designs, as-builts, or system certifications. Our guide to how a soil and site evaluation works covers what happens on the lot, usually $350-$700.

So on most Kaufman County projects, the evaluator supplies the design, the licensed installer assembles and files the package, and you sign and pay. You can't swap yourself in as installer without a TCEQ installer license, even on your own land. Our article on installing your own septic in Texas explains the ban, and the TCEQ license guide covers who may do what. For a new build, our septic system installation page explains how to get independent quotes from licensed installers.^source

The Certificate of OSSF Requiring Maintenance for aerobic systems

Every aerobic system in Kaufman County needs a notarized Certificate of OSSF Requiring Maintenance recorded in the county deed records. State rule 30 TAC 285.3 says this affidavit has to be recorded before the authorization to construct is issued, so it's on the critical path, not a closing formality. With about 98% of 2024 Kaufman County permits being aerobic or surface irrigation, most new homes need one.^source

The county's process is simple: print the form, fill in the legal description and owner names, sign it in front of a notary, file it with the County Clerk, then email the recorded copy to publicworks@kaufmancounty.net. The county form states that the system must stay under a continuous maintenance contract, that a signed contract must be submitted within 30 days after the property transfers, and that the owner will request a permit transfer on any sale.^source

This is where Kaufman County parts ways with the state. Texas lets an owner maintain an aerobic system personally after the initial two-year service policy. Kaufman County's order requires a licensed maintenance provider and a contract for the life of the system. Our article on why Texas requires maintenance contracts on aerobic systems walks through the reasoning.^source

How long does a Kaufman County septic permit take? The deadlines

The county has 30 days to approve or deny a complete application, and most of the other clocks are set by 30 TAC 285.3. The slow parts are usually outside those rules: getting an evaluator out, wet Blackland Prairie clay that nobody can trench, and builder scheduling. Most new installs run roughly three to six weeks once the evaluator and installer are booked. For how the septic steps line up with the slab, framing, and final, see our septic timeline for building a house in Kaufman County.^source

What the county inspects and what fails a septic inspection

The inspector compares what's in the ground to the approved planning materials, so anything that doesn't match the design is a deficiency. Kaufman County also checks its own local rules on top of the state ones. The most common problems come from field changes nobody ran past the designer.

• Tank, treatment unit, or pump tank that differs in size or model from the plan
• Spray area or drip field moved, shrunk, or reshaped to fit a driveway, shop, or pool
• Setbacks shorter than drawn, especially to a private well, property lines, or water lines
• Spray heads that aren't the purple pop-up type, or a timer not set to spray between 12am and 5am, both required by the county order
• No maintenance contract or recorded certificate on file for an aerobic system^source
• Work covered up before the inspector saw it; ask your installer how the county wants it left for inspection

After approval: what to keep and what you still owe

The notice of approval is the document that proves your system is legal, and it's issued in the owner's name. Keep it with the design, the site evaluation, and the recorded certificate. A buyer, lender, or inspector will ask for all of it when you sell. Our guide to selling a Kaufman County home on septic explains what they check.

For aerobic systems, approval starts the ongoing obligations. Your provider inspects every four months and must file contracts, renewals, and cancellations with Development Services within seven days. You submit the renewal 30 days before the contract expires, and the county charges a $25 annual renewal fee. The permit itself transfers to a new owner automatically on sale, but the new owner still has to get a signed maintenance contract on file.^source

Repairs, maintenance, and emergencies: which need a permit?

Replacing a tank or drainfield needs a new permit for the whole system, while routine maintenance needs none. Anything that raises permitted flow or departs from the approved plan is an alteration, and that needs a permit too. Our article on whether you need a septic permit in Kaufman County has the full project-by-project table.^source

Emergencies sit in between. Under 30 TAC 285.35, a licensed installer can fix an immediate health hazard first (a broken lid, riser, inlet or outlet device, chlorinator, or solid line) and report it in writing within 72 hours. A failed drainfield is not on that list. See the 72-hour emergency repair rule for what the report should say, and our septic tank repair service page or septic system replacement page if you need a contractor.^source

Skipping a required permit isn't a paperwork shortcut. Texas Water Code 7.174 makes it a Class C misdemeanor for anyone to start building, altering, or repairing someone else's septic system before the owner has the permit, and the county can also sue for an injunction or civil penalties. The practical cost is worse: a system without a notice of approval can stall a sale or have to be dug up.^source

How to look up an existing septic permit in Kaufman County

Email Development Services at publicworks@kaufmancounty.net or call 469-376-4127 and ask for the OSSF file on the property. Give the site address, the owner's name, and the Property ID from the appraisal district. The office is at 101 N. Houston Street in Kaufman, open weekdays 8 a.m. to 4:30 p.m. with a noon to 1 p.m. lunch closure.

Ask for the permit, the notice of approval, the planning materials, and for aerobic systems, the maintenance contract history. The county's own certificate form says a copy of the planning materials can be obtained from the county. The office may ask you to put the request in writing.^source

Some properties won't have a file. Systems installed before permitting began (September 1, 1989 statewide, and possibly January 1, 1988 under the county's original order) may be grandfathered with no record. In Terrell or Oak Ridge, the city holds the records, not the county. A maintenance provider's service reports can also fill gaps on aerobic systems.^source

City of Kaufman permits vs county septic permits

The City of Kaufman issues building permits inside its city limits, but Kaufman County issues the septic permit. City Development Services (972-932-2216) handles building permits, plan review, inspections, zoning, and platting, with applications through its MyGov online portal. The septic side still goes to the county's Development Services on Houston Street. The same split applies in Forney and Crandall.^source

Two cities run their own septic programs: Terrell and Oak Ridge. The county FAQ sends residents of both to their city. TCEQ also lists the City of Heath and the Tarrant Regional Water District as authorized agents, so near Heath or Cedar Creek Lake, confirm with them before anyone designs anything. Our city vs county septic permit guide shows how to check your parcel, and the Kaufman town page covers local conditions.^source

Out in the unincorporated county, "Kaufman County permits" can mean two different offices. The Fire Marshal's Inspections Division handles fire code permits for commercial and public buildings (469-376-4122, kaufmancountypermits.com). Septic is Development Services, regardless of acreage, because the county order switches off the state's 10-acre exemption.^source
