Chelsea-Hudson Yards, Manhattan
A consolidated public-record view · updated Oct 8, 2026
A building-level summary of matched filings, active-status records and published identifiers.
The lot
The lot holds a 12-story care home built in 1973, with 210 homes, on a 21,231 sq ft lot.
The apartments
40 condominium apartments are assessed on this block, and the typical one is 1,178 sq ft (109 m²). They run from 101 to 156 m².
The city values the typical one at $391,398. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
3 apartments on this tax block changed hands in the year the city last published, at a median of $1,385,000, from 1,150,000 to 1,740,000.
Recorded sale prices from the Department of Finance’s rolling file, covering the year to Aug 31, 2026. Transfers under $10,000 are left out: New York records deed transfers between relatives at a dollar, and those are not sales. No apartment number and no name is carried from either side.

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 matched set includes 2 alteration filing. Its latest status categories are 2 approved. 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.
