Regulatory framework
The code baseline for Sabine County.
Sabine County's Emergency Manager is the current county Floodplain Administrator. The county site publishes no general 2026 structural building-code edition or ordinary unincorporated building-permit program. OSSFs outside a local authorized-agent area are governed by Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285 through TCEQ Region 10. Within 2,000 feet landward of the Toledo Bend Reservoir project boundary, the Sabine River Authority of Texas is the authorized OSSF agent; its Board-approved June 19, 2025 rules also govern construction and limited uses on SRA-TX property and require written permit approval where applicable.
