You Need a Permit Before Installing a Septic System

Texas calls a septic system an OSSF. A permit is generally needed to build, change, extend, or repair one. Anderson County handles the local review outside city limits.

A ten-acre exception may apply to some single-family tracts. It requires a licensed site check, 100 feet from property lines, and no nuisance or water pollution. Some urgent repairs use separate notice rules.

The county can identify the permit, installer, and repair rules for the job. Keep the permit and final approval with the property records.
