The city values the typical one at $1,298,772. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
Owner of record
2014 52ND STREET, INC.
As the assessment roll records it. Only owners that read as a company are shown here; where the roll names an individual, nothing is published.

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 2 new building. Its latest status categories are 2 approved. Each filing page preserves its own status, dates, scope and source identifier.
