Commercial construction in Harlem
Harlem is Manhattan's brownstone/limestone row houses (1880-1915) submarket. Harlem has 5 separate LPC historic districts covering ~1,100 buildings — the highest number of distinct LPC districts in any single Manhattan neighborhood, each with its own design guidelines.
What a commercial construction project looks like here
Harlem has 5 separate LPC historic districts covering ~1,100 buildings — the highest number of distinct LPC districts in any single Manhattan neighborhood, each with its own design guidelines.
A disproportionate share of Harlem brownstones (~18%) carry HDFC (Housing Development Fund Corporation) deed restrictions that cap resale price and require income-level compliance — these properties also require HPD pre-approval for any renovation exceeding $25K.
Because much of Harlem's brownstone stock was built on filled-in wetlands, foundation waterproofing inspections frequently surface during renovations — a $15K-$45K French drain installation is often a prerequisite to DOB structural sign-off.
Retail, office, TI, mixed-use — DOB commercial filing stack plus ADA / NYC AC 28-309 compliance. In Harlem specifically, brownstone/limestone row houses (1880-1915) stock means commercial construction scope is shaped by the neighborhood's dominant construction typology.

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
Harlem commercial construction projects typically run $180K–$2.8M. Harlem's brownstone/limestone row houses (1880-1915) stock, combined with mount morris park + hamilton heights + sugar hill + astor row + st. nicholas — five lpc districts, puts most mid-complexity projects in the $1.5M range. Baily scopes the exact band once you describe the work.
