Regulatory framework
The code baseline for Terrell County.
Terrell County identifies the County Judge as its floodplain administrator/contact for development in unincorporated flood-hazard areas. The county publishes no general building department and no adopted countywide IRC, IBC, electrical, plumbing, mechanical, or fire-code edition. Terrell does not appear in TCEQ's current report of OSSF programs authorized through a local permitting agent; septic permitting therefore falls to TCEQ Region 7 under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285 unless the state confirms a newer local delegation.
