Public Advocate Bill de Blasio released on Tuesday his latest list of what he says are the worst landlords and buildings in the city.
Some 358 buildings are on the list, owned by 317 landlords.
At the top of the list of worst landlords is 1071 Home Corp, with 753 hazardous violations and five buildings on de Blasio's watchlist.
Three of the top five landlords have buildings in the Bronx, and two have buildings in Brooklyn.
Violations include lack of heat or hot water, lead paint, toxic mold or broken plumbing.
De Blasio launched the watchlist last year to publicly shame repeat offenders whose buildings don't meet city regulations.
Outing these owners, according to de Blasio, adds public pressure to have them make much-needed changes.
This year's worst building, 245 Sullivan Place in Crown Heights, Brooklyn, has 654 code violations.
Residents say the problems have gone on for years, from black mold to leaking ceilings and infestations of rats, mice and cockroaches.
