Permit authority in Westchester

Residential permits in Westchester route through the LADBS West LA branch. Plan-check typically runs 4–10 weeks for an addition and 8–14 weeks for a new build, with soft-story, hillside-grading and Title 24 sub-permits pulled alongside the master building permit.

Regulatory overlays that apply here

Westchester has no city-wide HPOZ, VHFHSZ, Coastal or hillside overlay flags that materially change the scoping conversation — standard LADBS or local-jurisdiction plan-check applies, with normal Title 24, structural, electrical and plumbing sub-permits.
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.
