240 Flatbush Avenue is a four-story, three-unit residential building located in Park Slope, Brooklyn, and managed by Derby Sloped 240, LLC. The 1920 Old Law Tenement building has experienced recurring maintenance issues in recent years, particularly related to heating and hot water systems. Between October 2023 and July 2025, there were multiple complaints about heat and hot water problems, with at least four instances requiring HPD intervention and subsequent violations being issued.

The building has also faced electrical challenges, including a power outage in February 2025, and ventilation concerns, with a recent indoor air quality complaint in April 2025. The property has been under continuous monitoring for various compliance requirements, including several active Local Law 188/17 Compliance Inspections, as evidenced by multiple complaints from 2023-2024. Notably, there was a period in 2023 when the building was cited for defective carbon monoxide and smoke detectors in Apartment 1, though these violations are now closed.

The building's mechanical systems have required attention, with emergency plumbing issues reported in April 2025, including radiator and water supply problems. While the building has generally maintained an active approach to pest control, recent bedbug reports (2021-2024) indicate no infestation cases. The property has passed rodent inspections in 2018 and 2024, suggesting basic pest management compliance. Other administrative matters include a currently active Environmental Control Board violation from 2024 regarding an unpermitted illuminated sign installation with a $4,000 penalty.
