Regulatory framework
The code baseline for Hall County.
Hall County’s official website lists county offices but no county building-permit, OSSF, or ICC-code program was identified. TCEQ Region 1 includes Hall County and is the state fallback for OSSF permitting, applying Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. Municipal jurisdictions may impose their own building requirements.
Inspection lane
Submit the February 2026 TCEQ-0235 application with the legal description, site/soil evaluation, planning materials, and licensed site-evaluator/installer information to TCEQ Region 1. Do not begin construction before Authorization to Construct. TCEQ requires approval or denial of complete planning materials within 30 days; confirm inspection scheduling and submission routing with Region 1 because no Hall County online permitting portal was verified.
