What a adu / dadu project looks like here

Beacon Hill sits on a distinct geographic ridge south of downtown — many homes have downtown skyline + Puget Sound views.

Because Beacon Hill Light Rail (2009) opened the neighborhood to TOD, residential value has risen sharply.

Jefferson Park Golf Course-adjacent parcels face specific fence-height and tree-protection rules.

Seattle's 2019 MHA rezone legalized DADUs (detached ADUs) + AADUs (attached) citywide — SDCI residential permit on standard path; MUP if ECA overlay. In Beacon Hill specifically, craftsman stock means adu / dadu scope is shaped by the neighborhood's dominant construction typology. Baily's Seattle scoping flow factors north beacon hill residential urban village and dadu + aadu by-right 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.
