NYC Department of Buildings (DOB) The city agency that regulates building construction, licensing of tradespeople, and structures like canopies and scaffolds that extend over the sidewalk.
DOB's authority overlaps with DOT's on jobs where a sidewalk shed, hoisting operation, or vault reconstruction ties into a larger building project — issuing Special Rigger and Master Rigger licenses, reviewing scaffold plans, and running the DOB NOW online filing system. For most straightforward sidewalk flag replacements, DOB doesn't get involved at all; it becomes relevant mainly when facade work, a sidewalk vault, or a canopy installation is part of the scope. Property owners doing a combined building-and-sidewalk project should expect filings with both agencies.
