Why junior adu (jadu) × Dallas produces this band

A junior adu (jadu) scope for a adu in Dallas combines two price levers: scope and metro labor rates. JADUs carve a ≤500 SF unit out of the existing primary structure with an efficiency kitchen (no range, induction cooktop allowed) and a shared or private bath. Cheapest ADU class when the jurisdiction recognizes it. Against the national median remodel labor rate, Dallas runs 8% below the national median — so the junior adu (jadu) band comes in 65% below the mid-range, then scales 8% below the national median on top of that. Permit timelines for residential work in Dallas typically run 3-8 weeks, which is the window you plan your design and decision sequence against. This page gives you the actual 2026 Dallas bands for this exact combination, plus the three cost drivers Baily asks about first when scoping the project live.

What drives cost for a junior adu (jadu) scope

What makes Dallas different

Labor — Non-union market with strong trade supply — labor rates 12-18% below national median.
Labor — Growing luxury remodel segment (Highland Park, University Park) drives premium-finish crew demand.
Labor — Foundation-repair demand is constant in North Texas (expansive clay soils) — pier-and-beam specialists busy year-round.
Material — Texas is a major distribution hub — most national brands have DFW warehouses, keeping lead times short.
Material — Summer thermal demand pushes HVAC sizing and spec higher than northern markets.

Dallas rules that affect this scope

City of Dallas Building Inspection Division handles permits; residential turnaround is typically 3-8 weeks.
Texas doesn't require state-level general-contractor licensing — vet GCs via BBB, references, and insurance certs.
Highland Park + University Park enforce independent municipal codes stricter than City of Dallas (setbacks, materials, height).
Flood-prone neighborhoods (Preston Hollow drainage, parts of Oak Cliff) trigger FEMA floodplain requirements.
