Do You Need a Septic Permit in Kaufman County? Rules, Cost, Timing

When is a septic permit required in Kaufman County?

A septic permit is required in Kaufman County any time you build, replace, alter, extend, or repair an on-site sewage facility (OSSF). That's the state rule in 30 TAC 285.3(a), and the county's own page says septic systems must be permitted before they are put into operation.^source

Kaufman County adds two local twists that matter. Its TCEQ-approved order, Section 10(A), requires a permit for every single-family dwelling regardless of acreage, which switches off the statewide 10-acre exemption. And the county says you must hold a TCEQ license to install or repair any portion of a septic system, sprinklers included.^source

This page answers whether you need a permit. For the step-by-step filing, see our Kaufman County septic permit process guide.^source

Which septic work needs a permit and which doesn't

The answer depends on which of four buckets the work falls into: new construction, alteration, repair, or maintenance. The definitions in 30 TAC 285.2 draw the lines, and they're more specific than most people expect.

Alter means any change that increases permitted flow, changes the kind of wastewater, departs from the approved plans, changes the construction, or lengthens or expands the treatment or disposal system. Repair means replacing any component outside the emergency list, and the rule says replacing a tank or drainfield requires a permit for the entire system. Maintenance, by contrast, includes routine checks, cleaning, adjustments, and replacing pumps, filters, aerator lines, valves, or electrical components, and does not include alterations.^source

The emergency repair 72-hour rule

An emergency repair can be made without a permit first, but it has to be reported in writing to the permitting authority within 72 hours after the work starts. In unincorporated Kaufman County that's Development Services.^source

The rule, 30 TAC 285.35, only covers repairs that abate an immediate, serious, and dangerous health hazard and that don't change the system's approved plans or function. Its examples are replacing tank lids, inlet and outlet devices, risers and riser caps, disinfection devices, damaged drip tubing, and solid lines.

The written notice must describe the methods and materials used, and the county can choose to inspect the repair. A cracked lid over a full tank qualifies. A new drainfield because the old one failed does not, no matter how urgent it feels. Our article on emergency septic repairs and the 72-hour reporting rule covers what the report should say.

What doesn't need a septic permit

Routine maintenance doesn't need a permit, and neither does an old system that has been left alone and is working. Everything else on this list comes with a condition.^source

• Maintenance: checks, cleaning, adjustments, and replacing pumps, filters, aerator lines, valves, or electrical parts. On aerobic systems in Kaufman County, a TCEQ-registered maintenance provider has to do it.
• Grandfathered systems: an OSSF installed before the cutoff date (September 1, 1989 statewide, possibly January 1, 1988 under Kaufman County's original order) that has never been altered, doesn't need repair, and isn't causing a nuisance
• Emergency repairs on the 285.35 list, if you file the 72-hour written report^source
• Connecting an RV or manufactured home to an existing rental space, if the existing system is not altered (285.3(f)(3))
• A change of ownership, because the permit transfers automatically^source

Who applies for a septic permit in Kaufman County?

The property owner or the owner's agent applies, and in practice your licensed installer usually assembles and files the package. The county's OSSF application has an owner signature block and a separate agent page, and an agent has to be someone with real authority to act for the owner.^source

Under 30 TAC 285.3(b), the application has to include the county form, the planning materials, the site evaluation, and the fee. Kaufman County's order is stricter about who produces the design: 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.^source

Aerobic systems add paperwork. The county's rules call for a two-year maintenance contract before the permit issues, and the state rule requires the owner to record an affidavit in the county deed records that the property has a system requiring continuous maintenance. Kaufman County's form for that is the Certificate of OSSF Requiring Maintenance.^source

Homeowners can't install their own system in Kaufman County unless they hold the proper TCEQ installer license. Our guide to who can legally work on a septic system in Texas covers the license types.^source

How the Kaufman County septic permit process works

The permit comes in two parts: an authorization to construct before work starts, and a notice of approval after the system passes inspection. Here's the sequence and the time limits the state rule sets at each step.^source

• Confirm jurisdiction: unincorporated county, or a city with its own program
• Soil and site evaluation and system design by a PE or RS with site evaluator certification
• Submit the application to Development Services at 101 N. Houston Street in Kaufman or by email to publicworks@kaufmancounty.net; incomplete applications are not accepted^source
• The county approves or denies within 30 days; a denial must be explained in writing
• The authorization to construct is valid for one calendar year; if no inspection is requested in that year, it expires and you reapply and repay
• The installer notifies the county at least five working days before the system is ready for inspection
• The county's designated representative inspects; if it fails, the county issues a deficiency letter within seven days, and Kaufman County charges a reinspection fee to the installer of record^source
• Within seven calendar days of passing, the county issues the notice of approval in the owner's name
• For aerobic systems, the maintenance contract and four-month inspections begin^source

How much does a septic permit cost in Kaufman County?

Plan on $400-$550 for the county OSSF permit and inspection, based on the ranges we track for Kaufman County projects. The county's OSSF page doesn't post a fee schedule, so confirm the current amount with Development Services at (469) 376-4127 before you budget.^source

The permit is rarely the expensive part. The site evaluation and design come first and usually run $350-$700, and the system itself is $6,000-$10,000 for conventional or $12,000-$18,000 for aerobic on most Kaufman County clay lots. Our septic cost guide for Kaufman County breaks those down.^source

How long does it take to get a septic permit?

The county has 30 days to approve or deny a complete application, and many projects move faster than that. The bigger time variables are getting the site evaluator out, weather on clay soil, and inspection scheduling.^source

Most new installs in Kaufman County take roughly three to six weeks once the evaluator and installer are scheduled. A wet spring can stretch that, because nobody wants to trench or set tanks in saturated Blackland Prairie clay.

Kaufman County issues a lot of these. TCEQ's historical data shows roughly 510 OSSF permits a year here in 2023-2025, and about 98% of 2024's reported permits were aerobic or surface irrigation systems. Your application is joining a steady stream, so a complete package matters more than calling every day.^source

City vs. county: who issues your septic permit?

Kaufman County issues septic permits for unincorporated areas and for any city that has an intergovernmental contract with the county. Areas inside incorporated cities with their own programs are outside the county order.^source

The county's FAQ tells Terrell and Oak Ridge residents to contact their cities about septic. A Forney, Crandall, or Kaufman mailing address doesn't settle it, because plenty of those addresses sit outside city limits. Check the parcel, not the mailbox. Our city vs. county septic permit guide shows how.^source

What happens if you skip the septic permit?

Skipping the permit can mean criminal charges, a civil suit, and a system you have to dig up. The penalties are modest on paper. The practical costs usually aren't.^source

Texas Water Code 7.174 makes it a Class C misdemeanor for anyone to begin constructing, altering, repairing, or extending a septic system owned by someone else before the owner gets the permit. That's aimed at the installer who says 'we'll get to the paperwork later.' Water Code 7.173 makes violating the state OSSF rules or a county order a Class C misdemeanor too, and repeat convictions carry heavier penalties. A Class C misdemeanor carries a fine of up to $500 under Penal Code 12.23.^source

Separately, Health and Safety Code 366.092 lets the county sue for an injunction, a civil penalty, or both. Kaufman County's order adopts the enforcement provisions in state law, and under 30 TAC 285.71 the county has to investigate complaints within 30 days. Nuisance complaints go to violations@kaufmancounty.net.

The bigger hit usually comes at sale. A buyer's inspector or lender asks for the permit and notice of approval, and there isn't one. Our guide to selling a home on septic explains why that matters.^source
