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.
No matching entry was returned from the DOB NOW occupancy dataset. This is not evidence that the building lacks a certificate; older documents may be in BIS.

Façade filings to review
| Filed | BIN / cycle | Filing classification |
|---|---|---|
| 2021-06-15 | 1046957 / 9 | SWARMP |
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
0 records marked Open in the matched HPD extract: none returned. 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.
