Application Process

  1. Verify first whether the property is actually in unincorporated Dallam County and not inside Dalhart, Texline, or either city's ETJ. The county subdivision regulations require city sign-off if a subdivision is within the ETJ of Dalhart or Texline.
  2. If the project involves subdivision of land, submit the plat and required drainage, water, sanitary-sewer, utility, tax-certificate, and survey materials for Commissioners Court review and approval.
  3. If the project requires an on-site sewage facility outside city limits, arrange design and installation through certified installers licensed by TCEQ under Environmental Health Department supervision and county inspector approval.
  4. If the site is in floodplain, contact the county floodplain administrator before development.
  5. If utility work will occur in county rights-of-way, notify Dallam County before the work and again before backfilling so the county can inspect the line depth.
  6. No public countywide general building-permit workflow was found for ordinary vertical construction in unincorporated Dallam County. For residential work, Texas HB 2833 private-inspection rules may be relevant depending on project type and legal applicability.
