Regulatory framework
The code baseline for Jeff Davis County.
The current Texas Floodplain Administrator directory lists County Judge Curtis Evans as Jeff Davis County's floodplain administrator, so development in mapped special flood hazard areas is subject to the county's NFIP floodplain review. The county website does not publish a general unincorporated-area building-permit program, zoning ordinance, adopted ICC structural-code edition, or building-inspection department. The county's FY 2026 budget continues to fund septic-tank inspections, but no current local OSSF application or adopted local order is posted; applicants should confirm jurisdiction with the County Judge. Where no locally authorized OSSF program applies, TCEQ Region 6 administers Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285.
