Green building in Somerville Davis Square

Somerville Davis Square is Somerville's triple-decker multifamily (1885-1920) — somerville is the densest triple-decker city in the united states — late-victorian single-family submarket. Somerville is the densest triple-decker city in the United States — roughly 6,000 triple-decker buildings on a 4.1-square-mile footprint — and its 1890-1920 framing convention is more standardized than even Dorchester, with predictable 2x10 joists at 16-inch on-center across a 24-foot span.

What a green building project looks like here

Somerville is the densest triple-decker city in the United States — roughly 6,000 triple-decker buildings on a 4.1-square-mile footprint — and its 1890-1920 framing convention is more standardized than even Dorchester, with predictable 2x10 joists at 16-inch on-center across a 24-foot span.

Because Somerville's Condominium Conversion Ordinance (originally adopted 1985, strengthened 2019) requires 1-5 year notice periods for tenant displacement and mandates right-of-first-refusal pricing, kitchen renovations on rental triple-decker units that prepare a unit for sale-as-condo trigger this notice clock and frequently delay the renovation by a full year.

Somerville's Climate Forward Plan (adopted 2018) offers utility rebates for kitchen renovations that include induction-cooking electrification + heat-pump HVAC retrofit — typical rebate stacking through Eversource + MassSave can offset 25-40% of the electrification scope on a kitchen project.

Boston Stretch Code (locally adopted 2010, opt-in Specialized Energy Code 2023), MassSave + Eversource rebate stacking, induction-cooking + heat-pump HVAC retrofits. In Somerville Davis Square specifically, triple-decker multifamily (1885-1920) — somerville is the densest triple-decker city in the united states — late-victorian single-family stock means green building scope is shaped by the neighborhood's dominant construction typology. Baily's Boston scoping flow factors mgl ch. 111 §197a delead on triple-decker stock (~92% pre-1978) and 780 cmr §722 fire-rated assemblies on triple-decker shared floors into the estimate before a contractor is involved.

Origin

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.
