505 Mcdonald Avenue, Brooklyn, NY 11218
The three-story, six-unit residential building at 505 McDonald Avenue in Kensington, built in 1930 and currently owned by Mohammed Hassan, has experienced several recurring maintenance issues in recent years, particularly relating to heat and hot water systems. Between October 2023 and June 2025, there were four documented heat and hot water complaints requiring HPD intervention, including two in 2024 and one in early 2025, with most cases showing restoration of service during inspections.
The building has also faced pest-related challenges, with multiple unsanitary condition complaints regarding infestations in 2021 and 2022, including two violations issued in December 2021. More recent inspections from December 2024 revealed several open violations, including roach infestation issues specifically affecting apartment 3R, along with problems related to self-closing doors. The building's safety compliance history shows some concerning patterns, including a carbon monoxide detector inspection in 2022 that required attention, and multiple emergency complaints in early 2022 related to various safety issues including plumbing and door conditions.
While three Local Law 188/17 compliance inspections in 2023 and 2024 resulted in either no violations or inspectors being unable to gain access, there are current violations from December 2024 regarding requirements for posting safety notices, including carbon monoxide detector requirements and gas leak procedures. Historical data shows some attention to rodent control, with inspections showing both rat activity and compliance passes between 2015 and 2022, though with some concern about inspections showing initial rat activity in 2021 and 2022. The building's bedbug reporting history from 2017-2019 shows no reported infestations during the required filings.
