“A string of bright beads of sunlight, breaking through the valleys along the moon’s rim.”

— Francis Baily, 1836

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.

Questions LA homeowners actually ask

Carson exterior projects run $15.3K-$184K in ZIP 90745 — the LA median on the $15K-$180K LA baseline. Facade refresh with paint and hardware: $15.3K. Curb-appeal package with entry door plus stone veneer: $45.9K. Full exterior re-clad with windows: $122K. Material $/sqft: 3-coat stucco $8-$20, fiber cement Hardie $8-$25, wood lap $12-$28, steel siding $18-$35.
Carson Building & Safety permits Carson exterior work — independent jurisdiction, not LADBS. Like-for-like re-stucco, re-roof, and window swaps qualify for express review in ZIP 90745. New openings, structural, or re-clad with framing exposure go to full plan check at 3-6 weeks. Exterior cladding assembly details are often deferred submittal — the general permit issues first and the cladding shop drawings come back for review before install.
Carson ZIP 90745 sits outside the mapped Very High Fire Hazard Severity Zone, so Chapter 7A ignition-resistant assemblies are not code-required here. Insurance carriers have still started pricing premiums against hardened exteriors — Class A CRRC-rated roofing, ASTM E2886 ember-resistant vents, and fiber cement or 3-coat stucco cladding. Adjacent VHFHSZ-mapped parcels on the same block often do trigger full Chapter 7A, so check the CalFire FHSZ viewer before finalizing materials.
Title 24 2025 locks in prescriptive envelope targets for Carson — exterior wall U-factor 0.051, fenestration U-factor 0.30, SHGC 0.23 in ZIP 90745. Replacing 50%+ of windows triggers whole-house energy compliance; a re-clad that removes siding and exposes framing triggers continuous insulation (CI) at the wall cavity. Re-roofs 2,000+ sqft trigger cool-roof CRRC reflectance and solar-ready conduit. Retrofitting CI mid-project after framing is closed costs about $4.6K in rework.
If the exterior scope adds square footage — bumped-out facade, enlarged entry, pop-up second story — BMO caps residential FAR at 0.45-0.50 of lot area in most Carson R1 zones (ZIP 90745). On a typical 7K sqft lot, that ceiling shapes how much wall surface can actually grow. Pure re-clad over existing framing does not consume FAR, so most exterior design projects here stay under the cap by staying within the existing footprint.
Carson R1 front-yard setback is 20 feet in most of ZIP 90745, so exterior features that push past the facade plane — pergolas, entry porticos, bumped-out bays — have to stay inside the setback envelope or request a zoning variance. Side-yard setbacks are typically 5 feet, limiting how far siding can oversail to cover new continuous insulation thickness without a zoning adjustment. LADBS zoning review catches this during exterior permit intake.
Traditional 3-coat Portland stucco is the LADBS default for Carson ZIP 90745 — scratch, brown, finish coats over 2-layer weather-resistant barrier, galvanized weep screed 4 inches above grade, and a 7-day moist cure per LADBS Bulletin P/BC 2017-083. One-coat synthetic stucco (EIFS) needs ICC-ES report plus drainage plane detailing and is often rejected on VHFHSZ parcels because it fails ASTM E136 non-combustibility. Cure time below 50F extends to 14 days.
