What can you build in Texas?

  • ADU rules vary significantly by city, and many jurisdictions prohibit ADUs outright.
  • Counties generally lack zoning authority, but other restrictions may still apply outside city limits.
  • Outside city limits, ADU feasibility often depends on subdivision rules, deed restrictions, and septic or fire requirements.
  • Building/fire codes are set statewide, but whether an ADU is allowed is local zoning.
