Robertson County's OSSF Order effective September 1, 2025 administers septic permitting under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. The county's 9-1-1 Addressing/Floodplain Administration office handles floodplain and zoning permits, and county subdivision review separately requires OSSF approval, addressing/road-name coordination, plat documents, filing fees, and Commissioners Court action. No general county structural building-code edition or ordinary unincorporated residential building-permit program was published for 2026. No county minor-structure or cosmetic-work exemption list was published. State OSSF exceptions for a qualifying single-family system on a tract of at least 10 acres, specified emergency repairs reported within 72 hours, and qualifying grandfathered systems are narrow and remain subject to all conditions and any more stringent Robertson County rule; confirm an exemption with the county OSSF Designated Representative before work.
