The lot

What is already here?

The lot holds a 1-story store building built in 1931, on a 2,000 sq ft lot.

  1. Floor 1Street levelStreet level. The lot is recorded as mixed residential and commercial, so this floor is where the commercial space is.
  • Street levelMixed residential and commercial
  • Above the southern skylineFrom about floor 8 — the tallest thing within 60 m to the south is 22.4 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 3.7 m over 1 floor, as the city counts them. 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.

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.

Lot facts come from NYC Department of City Planning, Primary Land Use Tax Lot Output (PLUTO) (64uk-42ks), accessed Sep 14, 2026. They describe the tax lot, not any single filing. When the rest of New York went up

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 3191791. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 11 alteration filing. Its latest status categories are 6 recorded as completed, 5 approved. Each filing page preserves its own status, dates, scope and source identifier.
