Application Process

Determine whether the project is in unincorporated Cooke County and whether it triggers county subdivision review, septic permitting, or floodplain limitations rather than a general county building permit.
For on-site sewage facilities, obtain a current 911 address and property ID number, complete the site evaluation and system design steps required by the Rural Septic Department, and submit the application online through MGO.
For subdivisions, file the subdivision application with the Subdivision and Development Department in Courthouse Annex Room 216. Applications are reviewed by the Rural Septic Department and Commissioners Court.
If the site is affected by floodplain issues, follow the county subdivision regulations and floodplain mapping requirements. The county subdivision regulations prohibit building construction on certain floodplain land until the required drainage improvements and FEMA map revision steps are completed.
If the project is ordinary building construction outside these verified county programs, confirm directly with the county whether any county approval applies.
