Required jurisdiction check

How long might review take?

How are inspections scheduled?
Submit TCEQ Form 0235, proof of the legal description, soil/site evaluation, planning materials, and applicable fee to the Region 3 OSSF Program. Do not begin construction until TCEQ issues authorization to construct; coordinate the required installation inspection with Region 3 at 325-698-9674 and leave components available for inspection. The state application authorizes TCEQ entry for site evaluation and investigation.
Which codes and exemptions should I review?
For unincorporated Mitchell County, the verified permit authority is the TCEQ Region 3 OSSF Program under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. The county's official website does not publish a county building department, structural building-code edition, general development permit, or county floodplain program for 2026; incorporated places may impose municipal building codes. Under state OSSF rules, the conditional 10-acre exemption may apply only to one single-family dwelling on a tract of at least ten acres after a licensed site evaluator or engineer evaluates it, when every system component is at least 100 feet from the property line, all effluent remains on the tract, and the system creates no nuisance or groundwater pollution. Listed emergency repairs may proceed without a prior permit but must be reported in writing within 72 hours. Grandfathering is limited to qualifying older, unaltered, non-nuisance systems. No county minor structural-work exemption was published.
