What the record shows

David Tennenbaum holds 83 buildings with a current record and 2,858 open violations between them. The weight is not even: 1529 Dahill Road accounts for 5% of it, while two of the 83 have nothing open at all. Tenants filed 5,813 complaints against these buildings in the last 12 months, spread across the portfolio rather than sitting in one address.

Where the buildings are 52 of the 83 buildings with a current record — 63% — are in Bronx, with the rest spread across three other boroughs. Brooklyn accounts for 16; Manhattan accounts for 14.

How the violations are distributed Open violations are not spread evenly across these buildings. 1529 Dahill Road alone carries 132 of them — 5% of everything open across the buildings with a current record — and 19 buildings hold half of the total. Behind it sit 643 Southern Boulevard with 128 and 344 East 209 Street with 124.

Violations per apartment Across 2,773 apartments the portfolio runs 1.03 open violations per unit. 40 buildings average at least one open violation for every apartment in them.

The split inside the portfolio 2 of the 83 buildings with a current record have nothing open against them today, while 81 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 5,813 complaints against these buildings in the last 12 months, or 2.10 per apartment. The heaviest was 2485 Elm Place with 925. 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 1926, and 78 of 83 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 295 Ft Washington 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 8,341 violations were written against these buildings in the last 24 months. 6,825 of them — 82% — have since been cleared, and 1,515 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.
