Contributor vs Non-Contributor

Dentro de cada HPOZ, cada property tiene un status — Contributor (historically significant to the character del neighborhood) o Non-Contributor (built later, or substantially altered). Contributors tienen MÁS strict review; propuestas para alterar original features requieren strong justification. Non-Contributors tienen más flexibility; pueden demolished o substantially renovated sin la same preservation scrutiny. Pregunta a tu real estate agent o check el HPOZ preservation plan para confirmar el status de tu casa.

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.
