Garage remodel — ADU garage conversion Cost in Chicago, 2026

Why adu garage conversion × Chicago produces this band

A adu garage conversion scope for a garage remodel in Chicago 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, Chicago runs 15% above the national median — so the adu garage conversion band comes in 65% above the mid-range, then scales 15% above the national median on top of that. Permit timelines for residential work in Chicago typically run 6-14 weeks, which is the window you plan your design and decision sequence against. This page gives you the actual 2026 Chicago bands for this exact combination, plus the three cost drivers Baily asks about first when scoping the project live.

• Material — Masonry restoration (common in pre-war Chicago brick) uses specialty materials with long lead times.
