Permit authority in Whittier

Whittier runs an independent building department separate from LADBS. City of Whittier (independent jurisdiction) enforces the California baseline code plus any locally-adopted amendments — allow 6–14 weeks for plan-check on a typical addition and 12–20 weeks for new construction.

Regulatory overlays that apply here

Very High Fire Hazard Severity Zone — Whittier parcels fall inside the state VHFHSZ map, which triggers California Building Code Chapter 7A (ignition-resistant construction). Class A fire-rated roofing, 1-hour exterior walls, ember-resistant vents, tempered-glass windows, and a 5-foot non-combustible perimeter (Zone 0) are mandatory on new builds and substantial remodels.
Hillside ordinance — sloped lots in Whittier trigger LA Municipal Code §12.21 C.10 (hillside ordinance) or the equivalent local ordinance: geotechnical review, haul-route permitting for soil export, ASCE 7 seismic design category re-analysis, and setback scaling by natural slope. For many additions this is the single biggest schedule driver.
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.
