Union Square is undergoing the most dramatic redevelopment of any Somerville neighborhood — the Green Line Extension station opened 2022 catalyzed the Union Square Master Plan zoning overlay that imposes step-back massing, ground-floor commercial, and inclusionary housing on parcels within a 600-foot station radius.
The Prospect Hill Historic District (designated 1989 by the Somerville Historic Preservation Commission) covers the flag-raising site of the first Grand Union Flag in 1776 — kitchen and bathroom renovations on contributing buildings here trigger HPC design review on visible work, parallel to the Cambridge Historical Commission posture in Mid-Cambridge.
Because Union Square's industrial-conversion loft stock (roughly 200 units in former 1890-1920 brick warehouses) operates under Somerville's Industrial Loft conversion overlay, kitchen renovations on these units must comply with 780 CMR §1003 egress rules originally designed for commercial occupancy — a frequent permitting friction point.

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.
