Unincorporated Cooke County

Verified county permits include OSSF (on-site sewage facility) permits and subdivision/development approvals. All septic permit applications must be submitted online through MGO. County subdivision regulations require applications through the Subdivision and Development Department and impose floodplain-related development limits. No countywide general building permit requirement for ordinary private building construction was verified.

Note: No public exempt-work list for a general county building permit program was found. The reviewed public record does not show a general countywide building permit program for ordinary construction in unincorporated Cooke County.

Building code

No public countywide adopted building code for ordinary construction was verified. Verified county controls involve subdivision regulations, floodplain development limits tied to subdivision rules, and OSSF regulation under Texas Health and Safety Code Chapter 366 and TCEQ authority.

Permit validity

No general county building permit validity rule found. Septic procedures and subdivision regulations contain program-specific rules.

Owner-builder

The county septic procedures allow owner-submitted conventional designs when the site evaluation supports a standard system. No county owner-builder rule for a general building permit program was found.

Contractor requirements

The reviewed county sources did not show a local county contractor registration program for general construction. Septic work follows state OSSF licensing and design rules.

1. 01
   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.
2. 02
   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.
3. 03
   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.
4. 04
   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.
5. 05
   If the project is ordinary building construction outside these verified county programs, confirm directly with the county whether any county approval applies.

Typical sequence: Septic permitting follows county OSSF procedures; subdivision approvals move through departmental review and Commissioners Court. No public sequence for a general building permit program was found because none was verified.
