Septic Systems in Galveston County Need an OSSF Permit

Galveston County Home & Property

A septic system is an on-site sewage facility, or OSSF. TCEQ says you usually need a permit and an approved plan before you build, repair, change, or operate one.

The design starts with a site check. Soil and drainage matter, so do not treat septic as a small add-on when you price land.

For Galveston County, TCEQ's 2024 authorized-agent report lists Galveston County Health District. If the land is not on public sewer, find the permit trail, ask what system type is allowed, and price repairs before closing.
