502 Clinton Avenue, Brooklyn, NY 11238

502 Clinton Avenue is a 4-story, 7-unit old law tenement building located in Clinton Hill and owned by Marc Katz. The building has experienced several significant maintenance issues in recent years, with the most pressing concerns centered around water management, ventilation, and building security systems. Most notably, in June 2021, the building underwent inspections revealing violations related to heavy water flow and door issues.

There have been recurring ventilation problems documented between 2019-2021, with multiple indoor air quality complaints filed with both HPD and DOHMH. The building has an open bedbug violation from April 2024, though previous years' filings indicated no infestations. The property has faced multiple compliance challenges regarding its cellar space, including an active violation from January 2020 concerning unauthorized occupancy of the cellar level, which was allegedly converted into a commercial laundry room contrary to its Certificate of Occupancy.

Additional violations from 2018-2020 remain open, involving requirements to post various safety notices in the common areas. The building's recent history shows regular maintenance issues being addressed, with several closed violations from 2021 related to repairs needed in Apartment 1, including work on the intercom system and various interior surfaces. While there have been multiple complaints about ventilation and air quality, inspections by the Department of Buildings have generally found no violations warranting penalties for these issues, though some complaints remain unresolved. The building's rodent inspections show mixed results, with a failure noted in November 2019, though a prior inspection in July 2013 passed.
