What it takes to build here — permits, zoning, and septic — scouted from Dallam County’s own official sources.
Dallam County's only land-use controls are subdivision platting and OSSF; consistent with Texas counties lacking authority to require building permits in unincorporated areas, no county residential building permit is imposed.
Dallam County Subdivision Regulations 2025 ↗The county regulates only subdivision platting and on-site sewage; Texas counties have no general zoning authority over unincorporated land and none is exercised here.
Dallam County Subdivision Regulations 2025 ↗The regulations state that in Dallam County OSSFs are permitted, inspected, and approved under TCEQ rules 'under the supervision of the Environmental Health Department,' i.e. the county acts as the local authorized agent.

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Texas’s water agency.
This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.
Texas groundwater is governed by the rule of capture; a Groundwater Conservation District must exempt qualifying domestic/livestock wells and may not restrict their production, but well registration and spacing rules can still apply and the exemption does not cover wells serving a platted subdivision.
Limit: Domestic/livestock well exempt from GCD production permitting if on a tract >10 acres AND incapable of producing >25,000 gal/day (Tex. Water Code §36.117)
Texas Water Code §36.117 / TWDB ↗TCEQ-designated northern-Panhandle Ogallala critical-groundwater area; drives GCD coverage. Domestic/livestock wells remain exempt but spacing/registration may apply.
TCEQ — Priority Groundwater Management Areas ↗Hybrid state (appropriation + riparian). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the Texas state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
