Regulatory framework
The code baseline for Sterling County.
Sterling County's County Judge serves as the county floodplain 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. Septic permitting is administered through TCEQ Region 8 under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. Incorporated Sterling City has a separate municipal floodplain authority and may impose its own requirements inside city limits.
