Application Process
- Confirm the property is in unincorporated Hamilton County and not inside Hamilton, Hico, or Evant.
- Determine whether the project triggers one of the county's narrower permit or approval programs: septic/OSSF, subdivision regulations, or culvert/entry permits.
- For septic or OSSF matters, obtain the Hamilton County septic application from the county permit page and coordinate the submittal path with the county.
- For subdivisions, follow the county subdivision regulations, which require concept, preliminary, and final plat procedures and an initial $1,000 deposit to the County Clerk when the preliminary plat is submitted to Commissioners Court.
- For a new drive, ranch road entry, or culvert replacement at a county-road entry, obtain a permit from the County Clerk or the appropriate County Commissioner, then contact the Commissioner for sizing and placement review.
- Do not assume Hamilton County issues a general building permit for ordinary vertical construction in unincorporated areas. Confirm permit requirements directly.
