What the record shows

Tf Cornerstone Inc holds 21 buildings with a current record and 22 open violations between them. The weight is not even: 33 Bond Street accounts for 55% of it, while 13 of the 21 have nothing open at all. Tenant complaints run the same way — 167 in the last 12 months, 34% of them from 33 Bond Street alone.

Where the buildings are 11 of the 21 buildings with a current record — 52% — are in Manhattan, with the rest spread across two other boroughs. Queens accounts for 8; Brooklyn accounts for 2.

How the violations are distributed Open violations are not spread evenly across these buildings. 33 Bond Street alone carries 12 of them — 55% of everything open across the buildings with a current record — and one building holds half of the total. Behind it sit 505 West 37 Street with 3 and 827 11 Avenue with 2.

Violations per apartment Across 9,192 apartments the portfolio runs 0.00 open violations per unit. No single building in the portfolio averages a full open violation per apartment.

The split inside the portfolio 13 of the 21 buildings with a current record have nothing open against them today, while 8 do. Portfolio-level averages hide that split, which is why the list is worth reading one row at a time.

What tenants called in Tenants filed 167 complaints against these buildings in the last 12 months, or 0.02 per apartment. The heaviest was 33 Bond Street with 56. Complaints and violations are separate records — a complaint that closed without an inspector getting inside leaves no violation behind it.

Age of the stock The median building here went up in 2007, and 2 of 21 predate 1960. Pre-1960 buildings carry lead-paint and window-guard obligations that newer stock does not, which shapes what turns up in an inspection.

How long things stay open The longest-standing open item in the portfolio is at 33 Bond Street and has been open 3.7 years. An old open violation is not a paperwork lag — it is a condition the city recorded and has not been shown to be corrected.

What has moved in the last two years 80 violations were written against these buildings in the last 24 months. 54 of them — 68% — have since been cleared, and 25 are still open. That ratio moves between city sweeps, which is why a standing total on its own says less than it looks like it does.

How buildings are linked: by HPD registration, deed, or a confirmed parent company. Being named as a head officer or managing agent is not the same as owning.
