What is recorded here
Multiple filings, one stable building identifier.
New York City's Building Identification Number helps connect filings that may use different application numbers or describe different scopes of work. The records below are grouped because they publish BIN 1036462. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 10 alteration filing. Its latest status categories are 10 approved. Each filing page preserves its own status, dates, scope and source identifier.
