What a adu / accessory dwelling project looks like here

Mount Holly is a Catawba River-front mill-town (founded 1875) — developed primarily 1900-1925 with textile mill-village cottage stock plus modern riverfront infill.

Catawba River waterfront parcels require Duke Energy shoreline management permits — separate process from City and Gaston County permits with 4-8 week added review.

Original mill-cottage construction is balloon-framed pine on post-and-pier foundations — almost every full remodel needs structural beam reinforcement and modern moisture remediation.

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.
