Septic Systems Need a Guadalupe County OSSF Permit

Away from city sewer service, a home may use an on-site sewage facility, or OSSF. Guadalupe County's rule is broad: every OSSF needs a permit, no matter the lot size.

For a build, change, extension, or operation, you need a License to Operate from Environmental Health or TCEQ. The packet asks for items like a site and soil check, recorded deed, appraisal card, and subdivision plat if there is one. Use that packet early. The soil can decide what kind of system works.
