Apartment layouts and floorplans
A verified floor-by-floor apartment map and reusable floorplan library are not yet available for this guide. Apartment labels in the sales table are record identifiers; they do not establish floor, bedroom count or a consistent layout across a line. We have not divided the unit total by the number of floors or guessed apartment sizes.
The matched DOB NOW occupancy dataset includes application CO-000101438, submitted 2026-09-25, with status CO Issued and 602 dwelling units in that record. This may cover a different scope than PLUTO; it does not certify today's bedroom mix or layouts. Review the actual certificate and amendments.

Façade filings to review
| Filed | BIN / cycle | Filing classification |
|---|---|---|
| 2023-02-02 | 1040460 / 9 | SAFE |
Latest dated filing per matched BIN in this extract. A filing classification is not a fresh inspection or a guarantee about present conditions. SWARMP means Safe With a Repair and Maintenance Program. Ask management for the latest accepted report, required work, contracts, budget and funding; a filing alone does not establish an assessment.

Housing maintenance record snapshot
3 records marked Open in the matched HPD extract: Class A: 1, Class B: 2. Matched by tax lot or building identifier; records may include other components of the property. This is a record snapshot, not a building quality score. An open record may concern a corrected condition awaiting administrative clearance, and no records returned is not a clean bill of health.
