Chicago Garage Conversion — Coach House, ADU Pilot, Alley Access
Chicago garage conversion. Many Chicago garages front an alley and have coach-house potential under ADU pilot. Structural evaluation, insulation for cold climate, egress, CDOB Standard Plan. $85K-$240K typical for full conversion.
Chicago's alley-fronting garages are the classic coach-house candidates. Under the ADU Pilot Ordinance (in pilot zones only), garages convert to accessory dwelling units with separate entry off the alley. Structural evaluation is critical — many 1920s Chicago garages weren't built for 2-story loads.

Who is Baily?
Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.
He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.
That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.
Baily was a businessman before he was a scientist. That’s our vibe too.
