300 Cortelyou Avenue, Staten Island, NY 10312
300 Cortelyou Avenue in Great Kills, owned by Becir Cosaj, is a 23-unit, 2-story building constructed in 1972 that has experienced several recurring maintenance issues over the past decade. Most notably, there has been a persistent rodent problem, with multiple inspections dating back to 2010 showing either failed inspections or documented rat activity, including recent bait applications in 2025, 2024, and 2023.
The building has also faced significant electrical issues recently, with two complaints in late 2024 regarding wiring and lighting problems that resulted in one emergency response from HPD, though they're now listed as closed. In terms of housing violations, there are several open Class A violations related to the annual bedbug report filings for the years 2019-2024.
Additionally, the property has a concerning history of mold-related complaints through 2021, when HPD was unable to complete inspections despite the emergency nature of these complaints. Security issues were documented in November 2019, with open violations regarding a broken entrance door lock and defective intercom system for all apartments. The building's management has demonstrated some compliance efforts, as evidenced by regular rat bait applications in 2024 and 2025, though the persistence of these issues suggests ongoing challenges with building maintenance and pest control in this 52-year-old structure.
