Septic Systems Need a Guadalupe County OSSF Permit

Out past the city sewer lines, a Guadalupe County home runs on an on-site sewage facility, a septic system. There's no acreage loophole here: the county requires an OSSF permit for every system, no matter how big the lot or how many acres surround it.

Before you build, alter, extend, or even operate one, you also need a License to Operate from Guadalupe County Environmental Health or TCEQ. The application packet is a real stack (a site and soil evaluation, the recorded deed, the subdivision plat if there is one, and other supporting documents), so it's not a same-day errand.

This is one of the first things to nail down on raw rural land, often before you've hired anyone. A quick call to Environmental Health for the current packet and inspection steps can save you from a soil test that fails after you've already paid an installer.
