City vs County Septic Permits in Kaufman County: Who Issues Yours

Who issues septic permits in Kaufman County?

Kaufman County Development Services issues septic permits for almost every property in the county. That includes unincorporated land, city ETJs, and most incorporated towns. The county's own FAQ puts it this way: if you are in Oak Ridge or Terrell, contact them, because those two cities are authorized agents, and all other city limits are handled by Development Services.^source

That surprises people. You might pull a building permit from the City of Forney or the City of Kaufman and still get your OSSF permit from the county building on North Houston Street. Two different offices, two different permits, one house.^source

Two other authorities show up in TCEQ's records for small pieces of the county: the City of Heath, for the part of Heath that sits in Kaufman County, and the Tarrant Regional Water District near Cedar Creek Lake. If your parcel is in either area, call them first.

Septic permit authority by town in Kaufman County

Use this table as a starting point, then confirm with the office named. City boundaries move with annexations and ETJ releases, and a mailing address like "Forney" or "Kaufman" tells you almost nothing about which side of a boundary a parcel sits on.

How to tell if you are inside city limits, ETJ, or unincorporated county

Check the parcel, not the address. The quickest free way is Kaufman County's GIS portal, which you can reach from the Development Services page. Search your full address or the property ID (PID), then turn on the layers for city limits and ETJ. The county says the map shows your city's ETJ along with flood zones and other jurisdictions.

Then cross-check it on Kaufman CAD's property search (esearch.kaufman-cad.org). Pull up the account and look at the taxing jurisdictions listed on the record. A city only taxes property inside its limits, so if a city shows up as a taxing unit, the parcel is almost certainly inside that city. If the only entities are the county, school district, and special districts, you are likely in an ETJ or unincorporated county.

If the two sources disagree, or the parcel was recently annexed or released from an ETJ, call. Maps lag behind city ordinances, and a parcel near Forney, Crandall, or Terrell can change status faster than the GIS layer updates.

• Open the county GIS portal and search your address or PID
• Turn on city limits and ETJ layers and note what the parcel sits in
• Look up the same parcel on Kaufman CAD and read the taxing jurisdictions
• If a city appears as a taxing unit, call that city and ask about sewer and OSSF
• If you are in Terrell, Oak Ridge, Heath, or near Cedar Creek Lake, call that authority before anything else
• Otherwise, confirm with Development Services at (469) 376-4127

Does the city or county handle septic in the ETJ?

In Kaufman County, the county handles septic permits in city ETJs. The county's TCEQ-approved order applies to all of Kaufman County except incorporated cities and areas already under another approved rule, and an ETJ is outside city limits.^source

Forney shows how the split works in practice. Its interlocal agreement with Kaufman County gives the city exclusive control of subdivision platting in its ETJ, while the county keeps exclusive jurisdiction over OSSF permits, floodplain permits, driveway culverts, and 911 addressing there. The same agreement says the county's OSSF authority extends inside Forney city limits wherever septic systems exist.^source

So if you are building on an ETJ lot outside Forney, expect the city to care about your plat and the county to care about your septic. If you are splitting land, both matter, and the county's 1-acre rule for lots on public water still applies to the septic side.^source

City of Kaufman permits vs Kaufman County permits

The City of Kaufman and Kaufman County are different governments with different permit offices, and both happen to be in the town of Kaufman. The city's Development Services department handles building permits, plan review, planning and zoning, and food and alcohol permits inside city limits. The county's Development Services handles permitting in unincorporated areas plus OSSF permits across most of the county.^source

If you are building inside City of Kaufman limits on septic, you will likely deal with both: the city for the house, the county for the septic system. Our Kaufman, TX service area page covers what building on septic around town usually looks like.

Terrell and Oak Ridge: when the city is your septic authority

Inside Terrell city limits, the City of Terrell issues and inspects septic permits. Kaufman County's own FAQ names Terrell as one of two cities that issue their own septic permits, so contact the City of Terrell directly for the application, fees, and inspection scheduling. A Terrell mailing address outside the city limits still goes to the county.^source

Oak Ridge is also its own authorized agent according to the county and TCEQ records. TCEQ's 2024 report shows Oak Ridge issued 43 authorizations to construct that year, so it runs an active program, not a paper one.

The state rules in 30 TAC Chapter 285 still apply in both cities, but fees, forms, inspection scheduling, and any stricter local rules come from the city. Do not assume the county's order, fee, or 1-acre language carries over.^source

Cedar Creek Lake and other special areas

Near Cedar Creek Lake, a parcel can fall under the Tarrant Regional Water District instead of the county. TCEQ's 2024 authorized agent report lists TRWD with activity in Kaufman County, and the county order carves out areas already regulated under an existing rule.

We could not confirm the exact boundary of TRWD's septic jurisdiction around the lake from a primary source, so we are not going to guess at a distance. Call TRWD and Development Services with the parcel ID before you design anything. Our Cedar Creek Lake septic guide covers the older lakeside systems you will run into down there.

What changes for you when the city is the authority

The biggest change is who you answer to. The city's designated representative inspects your system, the city sets the fee and the application form, and your aerobic maintenance provider files contracts and reports with the city instead of the county.^source

The licensing rules do not change. Installers, site evaluators, and maintenance providers still need TCEQ credentials anywhere in Texas. Our guide to who can work on your septic in Texas explains each license.^source

What to ask when you call about a septic permit

Call before you pay for a design, not after. Have the property address, the Kaufman CAD property ID, the owner's name, and a survey or plat if you have one. A five-minute call can save you a redesign.

Once you know the office, our Kaufman County septic permit process guide walks through the application, and do you need a septic permit covers repairs, replacements, and additions.^source
