Use & Occupancy Filing Sets

Use and occupancy filing sets are the documentation submitted to the NYC Department of Buildings to establish or change a building's approved use and occupancy classification. Obtaining a Certificate of Occupancy (CO) or a Letter of No Objection is required before a space can be legally occupied for its intended purpose.
