Permit triggers and exempt work for Dimmit County
No public countywide general building permit program was documented. Verified county controls are narrower: floodplain review for mapped floodplain properties, OSSF/septic permitting through TCEQ (with Dimmit County as authorized agent), and burn-permit restrictions during burn-ban periods.
Note: No public countywide exempt-work list documented. Contact the county directly for guidance on your specific project.
Application process

- 01 Confirm the parcel is in unincorporated Dimmit County and not inside Asherton, Big Wells, or Carrizo Springs city limits.
