Regulatory framework
The code baseline for Hardeman County.
Hardeman County’s official website lists county offices but does not publish a county building-permit or OSSF program. TCEQ’s regional directory places Hardeman County in Region 3 (Abilene), which is recorded as the state fallback for OSSF permitting under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. City jurisdictions may apply their own building and septic rules.
Inspection lane
Submit the current TCEQ-0235 application with the property legal description, site/soil evaluation, planning materials, and licensed evaluator/installer information to TCEQ Region 3. Do not begin work before Authorization to Construct. Complete OSSF planning materials must be approved or denied within 30 days; confirm local submission and inspection details with Region 3 because no Hardeman County online permit portal was verified.
