TCEQ must approve or deny a complete OSSF application and planning materials within 30 days. An approved MHRC plan must be recorded within 30 days after approval, but the county does not publish a typical initial subdivision, MHRC, or floodplain review duration.
How are inspections scheduled?
Submit subdivision or MHRC applications, supporting plans, and cashier's-check or money-order fees to the Irion County Clerk at the courthouse for review by the County Judge. MHRC construction and occupancy may not begin before plan approval; the county may inspect infrastructure during or after construction and issues the Certificate of Compliance only after conformance, which is required before utility service. Coordinate floodplain review with the County Judge's office and listed county Floodplain Administrator. For an OSSF under state jurisdiction, submit the TCEQ application and planning package to Region 8 and call 325-655-9479 to arrange required construction inspection before covering or operating the system.
Which codes and exemptions should I review?
Irion County adopted new Subdivision and Manufactured Home Rental Community Regulations on June 24, 2025 for unincorporated territory. They regulate plats, MHRC infrastructure, roads, drainage, stormwater and floodplain identification, water and sewer service, septic/OSSF planning, and utility connections. The current Texas Floodplain Administrator directory lists Bradley Fletcher for Irion County. The county publishes no general ordinary-building permit program, zoning ordinance, or adopted countywide ICC structural-code edition. In areas without a locally authorized OSSF agent, TCEQ Region 8 administers Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. No county cosmetic-work exemption list or general building permit is published. The 2025 regulations apply to nonexempt land divisions and manufactured-home rental communities in unincorporated Irion County; an owner claiming a statutory plat exemption should obtain the county's determination before selling lots or requesting utility service. State OSSF exceptions are limited to qualifying 10-acre single-family systems meeting every condition, qualifying grandfathered systems, and defined emergency repairs reported in writing within 72 hours. City of Mertzon requirements apply inside municipal jurisdiction.
