The Public Advocate's Worst Landlord Watchlist gets the headlines. It counts one agency's violations and weights building size, so a landlord holding hundreds of buildings and thousands of open violations can miss it entirely.
We did something simpler: ranked every landlord portfolio in our database by raw open violations across all agencies. A leak, a broken lock, no heat — each one counts once, in a walk-up or a tower.

A&E Real Estate Holdings
- open violations
- 22,345 open violations
- per building
- 93 per building
- buildings
- 240 Totalbuildings
A&E isn't just at the top of this list — they're in a category of their own. The nearest competitor carries nearly 10,000 fewer open violations. The city's $2.1 million settlement in January covered 14 of their 240 buildings, which leaves 226 properties — and thousands of tenants — outside the deal. We pulled the public record for every building in that settlement. It's grim reading.
Stellar Management
- open violations
- 12,384 open violations
- per building
- 27 per building
- buildings
- 465 Totalbuildings
The largest portfolio on this list. No single Stellar building dominates the headlines, and that's the point: spread across 465 buildings at 27 open violations apiece, it still adds up to the second-biggest pile of unresolved hazards in the city. Scale doesn't dilute a violation. It multiplies it.
Camber Property Group
- open violations
- 9,707 open violations
- per building
- 157 per building
- buildings
- 62 Totalbuildings
The density leader of the top three. Camber specializes in affordable-housing portfolios, which means the tenants living with those violations are the ones with the fewest alternatives.
Summit Properties USA
- open violations
- 7,805 open violations
- per building
- 99 per building
- buildings
- 79 Totalbuildings
Ninety-nine open violations per building, and nowhere on the city's watchlist. Summit is the first of four landlords in our top ten that the official list misses entirely.
M&T Real Estate
- open violations
- 7,300 open violations
- per building
- 20 per building
- buildings
- 359 Totalbuildings
Individually, each building reads as ordinary. Collectively, M&T is sitting on 7,300 unresolved hazards — more than several landlords the city does name. Also absent from the watchlist.
Progressive Management of NY
- open violations
- 6,472 open violations
- per building
- 39 per building
- buildings
- 164 Totalbuildings
Another scale story: the violations are spread just thinly enough to stay under the thresholds that get a landlord named.
DeMatteis Organization
- open violations
- 6,303 open violations
- per building
- 2,101 per building
- buildings
- 3 Totalbuildings
Three buildings. Nobody else on this list is close on density.
And it's really one building. 725 Lincoln Avenue, a sprawling Brooklyn complex, carries 6,002 open violations on its own — 95% of the entire portfolio. For the people living there, this isn't a portfolio statistic. It's the apartment.
Moshe Piller
- open violations
- 5,436 open violations
- per building
- 50 per building
- buildings
- 109 Totalbuildings
Like Summit, M&T, and Progressive, nowhere on the official list. Piller's buildings cluster in neighborhoods where tenants have the least leverage to organize.
Residential Management (NY) Inc
- open violations
- 5,414 open violations
- per building
- 61 per building
- buildings
- 89 Totalbuildings
On the city's watchlist — one of six in our top ten that are.
Alma Realty
- open violations
- 4,761 open violations
- per building
- 31 per building
- buildings
- 152 Totalbuildings
Alma rounds out a top ten where the gap to everyone else is measured in the thousands.
Dishonorable mentions
Just outside the top ten: Kew Gardens Hills LLC — 4,516 open violations across just 12 buildings, 376 per building, and invisible to the official list. Pistilli Realty Group (55 buildings, 4,695 open), Cafiero (50 buildings, 4,533 open), and Bronstein Properties (133 buildings, 3,757 open) all sit above 3,700.
What this list tells us
Size doesn't equal severity. Stellar has 465 buildings. DeMatteis has three. They're on the same list. Portfolio scale tells you nothing about what it's like to live in any one of the buildings.
Density is the lived experience. DeMatteis carries 2,101 open violations per building; M&T carries 20. Tenants don't experience the portfolio average — they experience their building. Always look at the per-building number, not the total.
The official list misses four of the ten. Summit, M&T, Progressive, and Piller hold over 27,000 open violations between them and appear on no official watchlist — the formula overlooks hazards spread thinly across many buildings. We found 44 such portfolios citywide.
One building can carry an entire portfolio. 95% of DeMatteis's open violations sit at a single Brooklyn address. Averages don't just hide bad buildings — they can hide a catastrophe.
Your landlord isn't "123 Main St LLC." It's a name on a list like this one — and the entity on your lease usually isn't the one that owns the building.
