Permit authority in Jefferson Park

Residential permits in Jefferson Park route through the LADBS Metro 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

HPOZ review — Jefferson Park sits inside or adjacent to a Historic Preservation Overlay Zone. Every exterior alteration (windows, roof, siding, front-door replacement, setback changes) requires a Certificate of Appropriateness (COA) from the LA Historic Preservation Board. Factor 4–8 extra weeks and rework-risk on any facade-facing scope.
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.
