Read from DOB License Info, published by the NYC Department of Buildings; our copy is from 2026-10-31. The name, address and phone are those the company filed with the regulator, reproduced as published. A permit shows the licence was on file the day it was filed. These rows show what the regulator holds now. The record is matched to Keystone Builders Group by company name, and only where that name resolves to exactly one licence in the register — a rule measured at 99.4% correct against permits whose licence number we already know. Verify with the authority before acting on it.
