730 Flatbush Avenue, Brooklyn, NY 11226

730 Flatbush Avenue, a 19-unit, 4-story New Law Tenement building constructed in 1905 in Prospect-Lefferts Gardens and currently owned by Julius Kairy, has experienced several recurring maintenance issues in recent years. The property has faced persistent heating and hot water problems, with multiple complaints between late 2024 and early 2025 affecting both individual apartments and common areas. Apartment 2C, in particular, has documented violations regarding inadequate heat, water leaks, and defective fixtures, while Apartment 3A has reported issues with pest infestations (including mice and roaches), water damage, and missing smoke detectors.

The building has also struggled with rodent and pest control, evidenced by multiple service requests and inspections in 2025 showing rodent activity, along with sanitary condition complaints concerning mold and pests. The Department of Buildings has active environmental control board violations related to unauthorized signage and occupancy issues, including a 2024 violation for multiple unauthorized signs with a penalty of $4,000 and a 2023 violation regarding illegal conversion increasing occupancy beyond the permitted limit. Previous investigations into possible illegal conversions occurred between 2018-2024, though inspectors were unable to gain access during these attempts.

History shows some structural and maintenance concerns, including water leakage affecting both residential and commercial spaces, particularly impacting a ground-floor store. The building has undergone several rodent inspections, with mixed results; while earlier inspections in 2019 and 2022 passed, more recent inspections in 2025 noted rat activity. It's important to note that many of these violations and complaints require the building owner to correct the conditions within specified timeframes, and some complaints were closed when inspectors were unable to gain access to the affected units.
