Why junior adu (jadu) × Austin produces this band

A junior adu (jadu) scope for a adu in Austin 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, Austin runs 5% above the national median — so the junior adu (jadu) band comes in 65% below the mid-range, then scales 5% above the national median on top of that. Permit timelines for residential work in Austin typically run 4-12 weeks, which is the window you plan your design and decision sequence against. This page gives you the actual 2026 Austin bands for this exact combination, plus the three cost drivers Baily asks about first when scoping the project live.

Labor — Tech-driven remodel demand has pushed labor rates above the Texas average; approaching national median.
Labor — Wet-season (spring) rain delays exterior trades.
Labor — Hill Country land demand fuels custom-home work which drains trade supply from remodel market.
Material — Limestone-heritage materials (Austin Stone, chopped limestone) carry local premium.
Material — High solar adoption (ERCOT grid economics) drives solar-ready electrical spec into remodel scopes.
