The lot

What is already here?

  1. Floors 2–4Nothing on record
  2. Floor 1Street levelStreet level.
  • Street levelThe way in
  • Above the southern skylineFrom about floor 7 — the tallest thing within 60 m to the south is 20.4 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 12.2 m over about 4 floors, counted at three metres each because the city publishes the height and not the number. 1 run of floors has something on record. The city publishes a roof height and a storey count for the lot, and nothing at all about any individual floor. What stands to the south is measured from the city’s own footprints and roof heights; it is a statement about the skyline, not a calculation of sunlight.

The apartments

70 condominium apartments are assessed on this block, and the typical one is 1,070 sq ft (99 m²). They run from 45 to 214 m².

The city values the typical one at $346,475. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.

What it sold for

4 apartments on this tax block changed hands in the year the city last published, at a median of $1,205,000, from 748,000 to 1,450,000.

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.

Owner of record

MZK MANAGEMENT GROUP LLC

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.

Violation record

Are there open violations here?

No open violations are recorded for this building.

Open means the agency has not recorded a resolution, which is not the same as the problem still existing. What a violation is, and what it is not. From NYC Department of Buildings, DOB Violations (3h2n-5cm9), accessed Sep 14, 2026.

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 3017526. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 8 alteration filing. Its latest status categories are 7 recorded as completed, 1 approved. Each filing page preserves its own status, dates, scope and source identifier.
