What the record shows
Where the buildings are 13 of the 23 buildings with a current record — 57% — are in Manhattan, with the rest spread across three other boroughs. Bronx accounts for 4; Brooklyn accounts for 4.
How the violations are distributed Open violations are not spread evenly across these buildings. 506 West 157 Street alone carries 12 of them — 16% of everything open across the buildings with a current record — and four buildings hold half of the total. Behind it sit 240 West 132 Street with 11 and 130 Adelphi Street with 10.
Violations per apartment Across 117 apartments the portfolio runs 0.65 open violations per unit. seven buildings average at least one open violation for every apartment in them.
The split inside the portfolio 9 of the 23 buildings with a current record have nothing open against them today, while 14 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 20 complaints against these buildings in the last 12 months, or 0.17 per apartment. The heaviest was 52 West 126 Street with 11. 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 1910, and 20 of 22 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 918 Summit Avenue and has been open 3.6 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 54 violations were written against these buildings in the last 24 months. 28 of them — 52% — have since been cleared, and 26 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.
