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 matched set includes 8 alteration filing. Its latest status categories are 3 recorded as completed, 5 approved. Each filing page preserves its own status, dates, scope and source identifier.
