Septic System Permitting for Houston-Area Counties

Septic permits can be confusing, and requirements change from county to county. We know the local regulations and guide you through the entire permitting process, so your system is approved the first time.

Overview

Septic permitting

01Why septic permits matter

In Texas, on-site sewage facilities (OSSFs), commonly called septic systems, are regulated by the Texas Commission on Environmental Quality (TCEQ) and by local authorized agents, usually the county. A system installed without the proper permit can be ordered removed, can delay a home sale, and can affect your ability to get a certificate of occupancy.

02How we help

  • Identify the permitting authority and requirements for your property
  • Prepare the design and supporting documents the county requires
  • Submit the application and respond to review comments
  • Coordinate required inspections during and after installation

03Counties we work in

We regularly work with Harris, Montgomery, Waller, Fort Bend and San Jacinto counties. You can find links to each county’s permit office on our county permit resources page.

FAQs

Septic permitting: common questions

Do I need a permit to install a septic system in Texas?

Yes. New and replacement septic systems generally need a permit and approved design before installation. Your county or authorized agent confirms the requirements for your property.

How long does septic permitting take?

Timelines depend on the county and how complete the application is. A correct, complete application prepared up front avoids most delays.

Can you handle design and permitting together?

Yes. Handling both ourselves means the design is prepared to match what your county needs to see.
