What a custom home design project looks like here

Sunnyside sits on the south slope of Mount Davidson — the 1925-1965 Marina-style + post-war stock layers onto rolling-hill topography unusual for SF's Sunset corridor.

Because hillside slopes exceed 15% on portions, DBI hillside-construction review applies on some parcels.

The 1925-1965 stucco-on-frame stock universally drives moisture-management + seismic stucco-band retrofit scope.

Ground-up residential — design through SFDBI permit through CFC. Article 10/11, view-corridor protections, hillside review, and §311 neighbor notification all stack on most parcels. In Sunnyside specifically, marina-style stucco bungalow (1925-1945) stock means custom home design scope is shaped by the neighborhood's dominant construction typology. Baily's San Francisco scoping flow factors hillside slope >15% on portions and stucco-on-frame marina-style construction 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.
