Project questions
Frequently asked questions for Cass County
Who handles permitting for this jurisdiction?
Northeast Texas Municipal Water District (NETMWD) OSSF Program / Cass County Commissioners’ Court is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 903-639-7538 (NETMWD OSSF); 903-756-5181 ext. 0 (Cass County Judge).
How long might review take?
N/A for ordinary OSSF permits; NETMWD’s published subdivision-planning rule allows written approval or denial within 45 days of receipt. Confirm current permit review timing with NETMWD.
How are inspections scheduled?
Submit the completed NETMWD permit packet, fee, site/soil evaluation, planning materials, scaled design, and required affidavit/maintenance documents to NETMWD before construction or septic repair. Contact the OSSF program at 903-639-7538 for inspection coordination and current submission instructions. Subdivision planning materials must be approved in writing before an OSSF application; the published state planning rule allows up to 45 days for that decision.
Which codes and exemptions should I review?
Cass County’s official website publishes no general county building-code edition or building-permit program; incorporated municipalities handle their own building permits. NETMWD is the TCEQ-designated OSSF representative for Cass County and applies Texas Health and Safety Code Chapter 366, 30 TAC Chapter 285, required site/soil evaluations, planning materials, and system-design standards. NETMWD states that a permit is generally required for a new water-using structure or septic repair/replacement in Cass County, except that a single-family home on a single deeded tract of at least 10 acres may qualify for the state 10-acre exemption if it is the only dwelling, is noncommercial, has a licensed site/soil evaluation, and all OSSF components are at least 100 feet from property lines. State emergency-repair and grandfathering rules may also apply when their conditions are met.
