ADU / accessory dwelling in Downtown
Downtown is Downtown's late-19th-century commercial + early-20th-century steel-frame high-rise submarket. Downtown Pittsburgh sits on the Golden Triangle peninsula at the confluence of the Allegheny and Monongahela rivers — most loft conversions originated as 1890-1925 steel-frame office buildings.
What a adu / accessory dwelling project looks like here
Downtown Pittsburgh sits on the Golden Triangle peninsula at the confluence of the Allegheny and Monongahela rivers — most loft conversions originated as 1890-1925 steel-frame office buildings.
Adaptive-reuse residential conversions in the Penn-Liberty corridor commonly retain original cast-iron columns and terra-cotta partitions, which trigger structural review under Title 10.
Because Downtown is in the PWSA combined-sewer overlay, any addition or change of fixture count over the threshold requires a stormwater management plan filing.
Pittsburgh ADUs — detached, attached, and conversion paths — scoped against Pittsburgh PLI + PA HICPA + 2018 IBC setback + height + parking variances. In Downtown specifically, late-19th-century commercial + early-20th-century steel-frame high-rise stock means adu / accessory dwelling scope is shaped by the neighborhood's dominant construction typology. Baily's Pittsburgh scoping flow factors penn-liberty historic district and 2018 ibc + pittsburgh amendments for adaptive-reuse change of occupancy into the estimate before a contractor is involved.

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.
