- 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.
- 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.
- If the site is in floodplain, contact the county floodplain administrator before development.
- 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.
- 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.
