Septic Systems in Harrison County Require a Permit
Outside city sewer lines, a Harrison County home often uses a septic system. Texas calls it an on-site sewage facility, or OSSF. Get a permit before installing, changing, or repairing one. TCEQ sets the state rules. Harrison County Environmental Health issues local permits and sends inspectors.
If you are buying rural land, ask about septic early. A bad or unpermitted system can cost real money and may slow a loan. Some single-family homes on under ten acres use a different path. More homes, a business use, or a park can still trigger permits and licensed installers.
