Who issues septic permits in Texas?

TexasReviewed October 2026

In Texas, septic systems (called on-site sewage facilities, or OSSFs) are permitted either by a local authorized agent or by TCEQ itself. An authorized agent is a local government, such as a county, city or river authority, that TCEQ has delegated to review permits, inspect systems and investigate complaints. Where no local program exists, the TCEQ regional office acts as the permitting authority. Authorized agents can adopt rules stricter than the state minimum if TCEQ approves them. The permitting authority must approve or deny a complete application within 30 days, and a denial can be appealed to its supervising body, such as the county commissioners court.

Check your local rule. This varies by state, county or city. Your permitting office has the final word; the official lookup pages below show you who that is.
