Why Cornice
Built by people who do this work every day.
Cornice was built by a practicing NYC construction project manager who manages a portfolio of 20+ buildings — the first user, the design partner, and the reference deployment are the same person's day job. We knew exactly what was missing because we'd lived without it.
Who do I call?
Know what specialist to hire.
Cornice doesn't perform inspections or repairs. For every violation we surface, we indicate the kind of licensed professional who does that exact kind of work — QEWIs for facade, master plumbers for LL152, QEIs for elevator, energy consultants for LL84 / LL87 / LL97, expediters for DOB. You contact them directly; Cornice points you in the right direction.
