Outside city limits in Kerr County, you likely need a septic permit

Outside public sewer, a Kerr County home may need an on-site sewage facility, or septic system. Kerr County Environmental Health handles OSSF permits and checks that systems follow TCEQ rules.

The site matters. Soil, slope, lot size, wells, and creeks can shape what kind of system is allowed. Thin Hill Country soil can make a simple plan harder.

Before buying rural land, ask whether a working, permitted OSSF is already there. A bad or unpermitted system can become your problem at closing. Kerr County's OSSF page has the permit forms and local contact.
