What homeowners miss that costs them money
- ⚠SFV costs run 10-15% below LA metro average - overlooked value opportunity
- ⚠Geotech report cost varies 3x ($1.5K flat lot vs $3K-$8K+ hillside) - budget accordingly before design
- ⚠LA all-electric mandate for new construction means no gas stub-outs - design all-electric from start to avoid retrofit
- ⚠Title 24 2025 is stricter than 2022 cycle - plans permitted before Jan 1, 2026 may still be buildable under 2022 but verify with LADBS
- ⚠Pacific Palisades and Malibu Coastal Commission review adds 3-6 months to permit timeline regardless of zoning

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.
