ADU Rules

What can you build in Santa Fe, TX?

Santa Fe, TX follows state and local rules for Accessory Dwelling Units. Here is a concise overview of the local rules.

Max Units

  • AR: 2 accessory apartments per lot (in addition to 1 principal dwelling); R-1: 1 accessory apartment per lot (in addition to 1 principal dwelling). R-2: 0; MH: 0.

ADU State Law

What can you build in Texas?

  • Texas does not have a statewide ADU law. ADUs are regulated entirely at the local level.
  • 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.
