ADU builder · Dallas, TX

The ADUs we design, permit and build around Dallas.

Four ways to add a second home to a lot, and one service that gets it approved. Which one fits depends on your city, your zoning district and your HOA.

How do these ADU types stack up?

A general comparison, as of October 2026. Dallas and each suburb set their own size and approval rules; Texas has no statewide ADU law.

Type	Where it goes	Main constraint	Often a fit when
Detached ADU	New building in the rear yard	City size caps, setbacks and lot coverage	The yard is deep and you want a separate home
Garage conversion	Inside an existing garage	Replacing required parking, slab condition	The garage is sound and parking can be met elsewhere
Attached ADU	Addition to the house	Fire separation and how the city classifies it	The yard is small but there is room beside the house
Garage apartment	Over a new or rebuilt garage	Height limits and neighbor privacy	You need to keep parking and the lot has an alley

Which ADU type costs the least?

Converting space that already exists usually costs less than new construction, because the foundation and roof are there. In Dallas, though, the approval step is the same for every type, so the gap is smaller than the construction numbers suggest. See the Dallas ADU cost guide.
