What is recorded here
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 1014387. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 63 alteration filing. Its latest status categories are 38 approved, 25 recorded as completed. Each filing page preserves its own status, dates, scope and source identifier.
Highest recorded values may come from different filings and must not be combined into one proposed project. Open the individual filings below for their exact scope. Values outside the publication's conservative data-quality bounds are withheld pending source review.
