What it takes to build here — permits, zoning, and septic — scouted from Johnson County’s own official sources.
Under Texas Local Government Code, counties lack authority to require residential building permits or perform building inspections in unincorporated areas; Johnson County issues development/floodplain and OSSF permits but not building permits, and cannot issue a Certificate of Occupancy.
Johnson County Development Services ↗Texas counties have no general zoning authority in unincorporated areas; Johnson County regulates land through subdivision platting and development permits rather than zoning districts.
Johnson County Land Development and Platting ↗OSSF (septic) permits are mandatory; a permit and approved plan are required to construct/alter/repair/operate an OSSF, administered by Johnson County as the TCEQ authorized agent with a required preconstruction site evaluation.

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 DFW-region Trinity/Woodbine 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.
