Seismic retrofit in Bonnie Brae

Bonnie Brae is Denver's 1930s-1950s tudor + ranch + mid-century submarket. Bonnie Brae is the 1922-platted curvilinear-street neighborhood south of Wash Park — its winding streets + larger lots distinguish it from the orthogonal Denver grid that surrounds it on three sides.

What a seismic retrofit project looks like here

Bonnie Brae is the 1922-platted curvilinear-street neighborhood south of Wash Park — its winding streets + larger lots distinguish it from the orthogonal Denver grid that surrounds it on three sides.

Bonnie Brae's 0.14-0.22 acre lots are 50-100% larger than Wash Park's typical 0.08-0.14 — drives a different remodel economics, with whole-home rebuilds rather than pop-top additions dominating since 2015.

The Bonnie Brae Tavern (closed 2017) anchored the neighborhood retail node at S University + Ohio — its replacement mixed-use redevelopment in 2020-2022 reset the area's land-value baseline.

Denver's late-1800s LoDo + Five Points + Curtis Park unreinforced-masonry stock — URM seismic upgrade triggers on adaptive-reuse + occupancy change; lower base hazard than the West Coast, but real on pre-1925 brick. In Bonnie Brae specifically, 1930s-1950s tudor + ranch + mid-century stock means seismic retrofit scope is shaped by the neighborhood's dominant construction typology. Baily's Denver scoping flow factors denver zoning code u-su-c + u-su-d and denver slot home regulation 2018 into the estimate before a contractor is involved.

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.
