John Warren is listed in NYC building registrations or deeds for 77 buildings. Brix tracks 2,868 open violations across the buildings listed below, with an adjusted rating of concerning.
John Warren holds 77 buildings with a current record and 2,868 open violations between them. The weight is not even: 111 East 100 Street accounts for 8% of it, while six of the 77 have nothing open at all. Tenants filed 3,566 complaints against these buildings in the last 12 months, spread across the portfolio rather than sitting in one address.
Where the buildings are 29 of the 77 buildings with a current record — 38% — are in Bronx, with the rest spread across three other boroughs. Brooklyn accounts for 22; Manhattan accounts for 20.
How the violations are distributed Open violations are not spread evenly across these buildings. 111 East 100 Street alone carries 231 of them — 8% of everything open across the buildings with a current record — and 11 buildings hold half of the total. Behind it sit 114-05 170 Street with 193 and 920 Kelly Street with 181.
Violations per apartment Across 1,635 apartments the portfolio runs 1.75 open violations per unit. 48 buildings average at least one open violation for every apartment in them.
The split inside the portfolio 6 of the 77 buildings with a current record have nothing open against them today, while 71 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 3,566 complaints against these buildings in the last 12 months, or 2.18 per apartment. The heaviest was 111 East 100 Street with 332. 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 1914, and 66 of 77 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 22-45 Dix Avenue and has been open 4.0 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 3,820 violations were written against these buildings in the last 24 months. 1,840 of them — 48% — have since been cleared, and 1,979 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.
