Required jurisdiction check

Project questions
Frequently asked questions for Marion County
Who handles permitting for this jurisdiction?
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
How should I begin an application?
No verified online portal was located in the reviewed public materials. Contact City of Jefferson: 903-665-3922; NETMWD OSSF Program: 903-639-7538; Marion County courthouse: 903-665-3261 and request the current application route before preparing a final submittal.
How long might review take?
Jefferson requires approved construction to begin within 90 days and be completed within 270 days; only City Council may grant an extension or amendment. NETMWD publishes no standard review duration, warns that complex nonstandard systems may require additional TCEQ review, and makes an OSSF Authorization to Construct valid for one year from issuance.
How are inspections scheduled?
Submit Jefferson building applications and plans to City Hall at 305 E. Austin Street or call 903-665-3922. The application authorizes inspections during construction, including plumbing rough-in, before concrete placement, after framing, before closing interior walls, and at final; completed plumbing connected to city water or sewer also requires a Customer Service Inspection. For OSSF work, submit NETMWD's complete packet with the site/soil evaluation, scaled planning materials and design, applicable aerobic affidavit and maintenance contract, fee, and directions. After Authorization to Construct, call 903-639-7538 for inspection before covering any part of the system; stop work and submit any design changes for review. Approval to Operate follows a compliant inspection and complete documentation.
Which codes and exemptions should I review?
Marion County's current hazard plan states that the unincorporated county does not participate in the NFIP, lacks current FEMA flood mapping, and the county site publishes no structural building-permit or ICC-code program. The municipal fallback, City of Jefferson, confirms the 2000 International Building Code as its last clearly adopted building code. A 2026 ordinance proposing the 2021 IBC, IEBC, IFGC, IRC, IMC, IPC, ISPSC, private sewage disposal, and fire codes plus the 2023 NEC received first- and second-reading agenda consideration, but the city's ordinance page still lists it as a draft rather than an adopted ordinance, so those editions are not represented here as effective. NETMWD administers Marion County OSSF permits under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. No unincorporated-county cosmetic-work exemption list was found. The City of Jefferson application exempts relocation of a structure to another location on the same or adjoining property from the $100 moving fee, but not from review, and requires sprinkler/irrigation approval before installation. For OSSF, confirm any state-law 10-acre single-family exception with NETMWD; the exception requires at least 10 acres, all disposal lines at least 100 feet from property lines, retained effluent, and no nuisance or groundwater pollution.
