The 2025 rendition of the “Worst Landlord Watchlist” in New York City was released on Wednesday by the Public Advocate’s Office.
Among the 100 landlords deemed the worst in the five boroughs by the number of housing violations given by the city’s Department of Housing Preservation and Development between December 2024 and November 2025, there were five with properties on the Upper West Side.
In total, those five landlords own seven buildings in the neighborhood.
“Each hazardous violation on the Worst Landlord Watchlist, each building in disrepair, each landlord putting profit over people, represents New Yorkers suffering in their homes,” said Public Advocate Jumaane D. Williams, in a news release.
There was one Upper West Side landlord featured in the 2025 ranking who owns multiple buildings on the Upper West Side.
Adam Jernow: 77th worst landlord in New York City for 2025
- 15 West 75th Street (between Columbus and Central Park West): 191 violations
- 47 West 74th Street (between Columbus and Central Park West): 84 violations
- 122 West 71st Street (between Columbus and Amsterdam): 75 violations
The 15 West 75th Street building has long been a troubled property, first appearing on the Worst Landlord List in 2014. There is currently a violation for “failure to certify correction of a Class 1 Violation” on the address, according to the New York City Department of Buildings’ portal.
A Class 1 Violation is the most severe of an “Immediately Hazardous” designation given out by the DOB, which requires immediate correction by the property’s owner, or be served with a fine or stop work order.
Complaints related to the property include the elevator not operating consistently and concerns about the building’s foundation shifting, according to the DOB portal.
Here are the four other landlords featured on the most recent Worst Landlord Watchlist with properties on the Upper West Side.
David Deutsch: 42nd worst landlord in New York City for 2025
- 250 West 72nd Street (between West End and Broadway): 67 violations on this building (641 violations across all buildings)
David Manheimer: 71st worst landlord in New York City for 2025
- 209 West 107th Street (between Broadway and Amsterdam): 45 violations on this building (546 violations across all buildings)
Alex Kaskel: 88th worst landlord in New York City for 2025
- 495 Amsterdam Avenue (near the corner of West 84th Street): 29 violations on this building (490 violations across all buildings)
Chris DeAngelis: 95th worst landlord in New York City for 2025
- 964 Amsterdam Avenue (between West 107th and 108th streets): 151 violations on this building (476 violations across all buildings)
The very worst landlord of this year’s list, or the No. 1 ranked, was Margaret Brunn, who has 4,872 open HPD violations across 24 New York City buildings.

A mere 5%, with the worst offender at only the 42nd position?
We must do better, UWS!
The problem with the list is there’s no reason for an owner to go through the process of clearing violations that have been cured unless they are refinancing or selling.
If you see an “open violation” of no hot water at a building on W75 St from 2021 do you think there’s no hot water there today? I can all but guarantee you that there is.
I am not saying these are good landlords or that the list is useless. But it is a rather lazy effort that should have limited impact.
I can think of a few more who should be on this list.
Of course, the worst of the worst is actually The City Of New York.
