Room additions in Arlington Center
Arlington Center is Arlington's late-19th-century single-family + 2-family (1880-1910) submarket. Arlington Center sits along the Massachusetts Avenue corridor between Cambridge Porter Square and Lexington Center — the corridor's 1900-1930 commercial-residential character produces a mixed permitting environment where kitchen and bathroom remodels in the side-street single-family blocks move through Arlington ISD on baseline timelines but corridor-fronting parcels engage zoning review.
What a room additions project looks like here
Arlington Center sits along the Massachusetts Avenue corridor between Cambridge Porter Square and Lexington Center — the corridor's 1900-1930 commercial-residential character produces a mixed permitting environment where kitchen and bathroom remodels in the side-street single-family blocks move through Arlington ISD on baseline timelines but corridor-fronting parcels engage zoning review.
Because Arlington adopted a town-meeting-form government and operates without a city manager, its Inspectional Services Department has historically run faster permit-review timelines than comparable city-government departments — kitchen permits here typically clear in 3-5 weeks versus 6-10 weeks in Cambridge.
Arlington's Wetlands Protection Bylaw imposes stricter buffers than the state default — 100-foot riverfront buffer expanded to 200 feet on parcels adjacent to Mill Brook and Spy Pond — and the Conservation Commission filing requirement adds 4-8 weeks to a kitchen-relocation permit when foundation work is involved.
Rear-yard additions on pre-war row houses, dormer expansions on triple-deckers, rooftop bulkheads on flat-roof buildings — ISD long-form permit on envelope expansion. In Arlington Center specifically, late-19th-century single-family + 2-family (1880-1910) stock means room additions scope is shaped by the neighborhood's dominant construction typology. Baily's Boston scoping flow factors arlington historical commission and mgl ch. 111 §197a delead on pre-1978 stock (~80%) 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.
