The Comal County Engineer's Office lists what you need when building in the unincorporated county. A single-family house does not get a county building permit: Fire Marshal permits apply to commercial and public buildings and to multifamily buildings of four or more units. Property owners associations may add their own rules, so read your deed restrictions too. The full list is on the county permits page.

Canyon Lake septic permits

State and county law require a Comal County OSSF permit before anyone builds or makes a non-emergency repair to a septic system, and the application goes in with a design from a registered engineer or sanitarian. A homeowner may maintain their own aerobic system if it serves a single-family home.
