Garage remodel — ADU garage conversion Cost in Houston, 2026

Why adu garage conversion × Houston produces this band

A adu garage conversion scope for a garage remodel in Houston combines two price levers: scope and metro labor rates. Converting a garage into a permitted ADU adds everything in the living-space conversion PLUS a full kitchen, full bath, independent entrance, and usually independent utility metering. Most common ADU path in many cities. Against the national median remodel labor rate, Houston runs 5% below the national median — so the adu garage conversion band comes in 65% above the mid-range, then scales 5% below the national median on top of that. Permit timelines for residential work in Houston typically run 3-8 weeks, which is the window you plan your design and decision sequence against. This page gives you the actual 2026 Houston bands for this exact combination, plus the three cost drivers Baily asks about first when scoping the project live.

• Material — Flood-zone construction requires elevated utilities and waterproof-rated materials within the AE and X-shaded areas.
