Can you build an ADU in Dallas, TX?

Unclear — verify with the town

The provided ADU source is a 2020 proposal/study document and does not confirm current adopted citywide by-right ADU rules. Some ADUs were historically approved through Board of Adjustment processes, and an ADU overlay tool exists, but current permissibility must be verified parcel-by-parcel.

Accessory Dwelling Unit (ADU) rules

The provided ADU source is a 2020 staff/ZOAC case report considering whether ADUs should be allowed by right and whether an opt-out process should be created. It confirms that, at that time, there were existing processes to allow ADUs and that the Board of Adjustment had granted two ADUs for rent in January 2020, but it does not prove the current final adopted citywide rule in 2026.

  • Verify current adopted ADU rules directly in the current code and with city staff
  • Do not rely on the 2020 proposal document as proof that ADUs are now allowed by right citywide
  • ADU overlay is described in city educational materials as a zoning tool applicable in areas allowing single-family uses where ADUs are not expressly prohibited
