4512 6th Avenue, Brooklyn, NY 11220

4512 6th Avenue is a 3-story, 6-unit New Law Tenement building constructed in 1914, currently owned by Daizhen Zhou and located in Sunset Park. The most pressing recent concern is a heat and hot water issue reported in late October 2024, though these services were reportedly restored during the inspection process. The building has experienced multiple maintenance challenges in recent months, particularly during October 2024, when multiple complaints were filed regarding various building systems including plumbing, electrical, ventilation, and door/window issues.

These complaints were notable for the pattern of inspectors being unable to gain access for proper evaluation, though they were ultimately closed. The building has several outstanding safety concerns as of October 2023-2024, including two open Class C violations from December 2023 related to self-closing doors (in Apartment 3R and the first story vestibule) and a missing heating system notice. Notable past issues include documented problems with excessive hot water temperatures in Apartments 2R and 3R, visible mold in Bathroom 3R, and concerns about a defective carbon monoxide detector in Apartment 2R.

The building's rodent history shows a mix of compliance and violations between 2018 and 2022, with multiple instances of rat activity followed by passed inspections. An annual bedbug report for 2022-2023 showed no infestations or treatments. While many violations have been addressed and closed in recent months, the pattern of complaints and inspection access issues suggests ongoing challenges with building maintenance and communication.
