Who Permits Septic Systems in Fort Bend County
Which office handles your septic comes down to one question: is your land inside a city's limits? On unincorporated land, the answer is Fort Bend County Environmental Health.
The county also permits septic inside Beasley, Fairchilds, Fulshear, Simonton, Weston Lakes and Pleak, by agreement. Inside other cities, the state's Houston regional office (TCEQ) does.
Septic Inside Fort Bend City Limits
Own a home inside Sugar Land, Stafford, Missouri City or Katy? The county doesn't permit septic there, and most homes are on city or utility-district sewer. An older system still needs care, so call us if you have questions about your system. Just past Houston's southwest edge, Harris or Fort Bend County permits septic in Bluebonnet Acres and McIntyre Acres.
When the Mailing Address Says Richmond
A Richmond or Rosenberg mailing address doesn't tell you who permits your system, because many of those addresses sit on county land. West of Richmond off FM 359 and McCrary Rd, acreage homes run their own septic and wells. Not sure which side of the line you're on? Send us the address. We'll help you confirm which office permits your address.

The Permit Process
How a Fort Bend County OSSF Permit Works
Building new, replacing or changing a system? Each one needs a permit before the work starts. In the county's paperwork, your septic system is an on-site sewage facility (OSSF).
The county sets the permit fee and can change it, so check the county's current fee schedule before you budget. The steps below run in order.
Site Evaluation and System Design
Before anything is filed, a professional engineer or registered site evaluator looks at the lot and the soil, and an engineer or registered sanitarian draws the design from what they find. The design sets the type of system, its size and where it sits, so it's worth getting right the first time. Our septic design and permit drawings page explains how that part works.
Filing Online With the County
Applications go to the county online only. A new aerobic system also needs a signed two-year service contract and a recorded affidavit filed with the application, so have both ready before you submit. Maintenance contracts are filed online too, and on an Advantage Plan, we submit the correct renewal paperwork to the county.
County Sign-Off Before Use
Once the system is in, the county inspects it with the trenches still open, and nobody can use it until the county issues its approval. If you're planning a new septic system installation, build that last step into your move-in plans so it doesn't hold you up.
How We Handle Your Permit
You shouldn't have to learn the county's process to build a house or fix a system. We'll get your system designed and permitted. From the site evaluation and design to the application, we make sure your permits get submitted correctly. On our installs, the permit is usually included in the price of the job. It's part of our septic service across Fort Bend, Brazoria and nearby counties.
Aerobic Rules In Fort Bend
What Fort Bend Requires of an Aerobic System
Putting in a new system? Most ground in Fort Bend is clay or loam that soaks water in slowly, which makes a standard drain field a poor fit.
That's why most new systems in our area drip or spray instead. If yours is an aerobic system, the county has rules of its own for it, and we can keep up with them for you.
A Licensed Provider Every Four Months
Once an aerobic system is in, a licensed provider must check it every four months. It comes with a two-year contract, so the checks are set up from the day the system starts running. Each visit looks at the moving parts that keep the water clean. Our aerobic maintenance contracts that meet the county rule cover the four-month visits for you.
Renewals and the Yearly County Fee
When the first two years are up, the contract renews, and the county charges a yearly fee on renewals. The county requires the contract to stay current, so a lapse is worth sorting out quickly. If yours has run out or you're not sure who holds it, tell us, and we'll get it back on track.
WHERE WE WORK
Fort Bend Towns We Cover
Own acreage outside Richmond or Rosenberg? Past the city limits, the county permits septic, and that's where most of the tanks are. Inside both towns, homes are mostly on city sewer, and owners with an older system are welcome to call us.
Around Needville, the county permits septic outside the city limits, where homes on tracts of 5 to 8 acres run their own septic and wells. Simonton has no city sewer, so homes there run well and septic. In Fulshear, septic sits on estate lots like original Fulbrook and North Fulshear Estate.
Around Fresno, the county permits septic in the older acreage subdivisions off FM 521, such as Ridgewood Estates and Fresno Ranchos. Past Sugar Land's city limits, the county permits septic in places like Four Corners and Hidden Lake Estates. Wherever you are on this list, we'll make sure your permits are done right.

Acreage And Repairs
Lot Size, Wells and the 10-Acre Exemption
Buying land to build on, or planning a change to the system you already have? Fort Bend County's septic regulations on lot size and repairs are stricter than many owners expect.
Knowing the rules below before you buy, build or change anything saves you a redesign later. We check every plan against them from the start.
Why Acreage Does Not Exempt You Here
Some Texas counties let one home on a tract of ten acres or more go without a septic permit. Fort Bend isn't one of them: the 10-acre exemption doesn't apply here. A house on forty acres needs a permitted system just like a house on one, so build the permit into your plans from the start.
One Acre for a Well Plus Septic
A lot with both a private well and a septic system needs at least one acre. A smaller lot platted before 1988 can still work, but it needs a professional design. If you're looking at land, check the lot size and when it was platted before you buy. We're happy to look over a listing with you first.
Repairs and Changes Need a Permit Too
Fort Bend doesn't grandfather existing systems. Any change to a system here needs a new design and a permit, even when it's been working for years. Before you replace or add to any part, talk to us. We'll explain what's involved and handle permitted septic repairs from design to sign-off; the permit is usually included in the price, and we make sure it's handled correctly.
