You Need a Permit for a Septic System in Comal County

A septic system is also called an on-site sewage facility, or OSSF. Before you build, change, extend, or use one, you need a permit and an approved plan. TCEQ or its local agent, Comal County, handles that step.

First, a trained person checks the site and soil. The results help set the system type. They also help place it away from the home, lot lines, wells, and other features.

Comal County reviews the design and checks the work. Start before you pick the house site or close on a hard tract. Thin soil, slope, a floodplain, or the Edwards recharge zone can change the plan.
