Augrented Insights Report for 531 Lenox Avenue

The 10-unit, 5-story tenement building at 531 Lenox Avenue in Harlem, owned by Karen Geer, has experienced persistent maintenance issues over the past several years, with the most pressing concern being recurring problems with heat and hot water throughout the entire building. From 2023 through 2025, there have been multiple emergency complaints (eight instances) specifically related to inadequate heat and hot water service, with the most recent incidents occurring in late April 2025.

The building currently has three open emergency violations as of May 2025 concerning safety issues with carbon monoxide detectors, smoke detectors, and door problems. The property has also faced several significant maintenance challenges in recent years, particularly in Apartment 4B, which has multiple open violations from January 2024 related to rodent infestation, water leaks, damaged vinyl floor tiles, and deteriorated plastered surfaces. There was one violation issued in December 2024 for a defective radiator in Apartment 5A.

The building's heating system has been problematic, with a 2019 Department of Buildings violation regarding an inoperative boiler and a related Environmental Control Board violation regarding a Lochinvar boiler. While the building's bedbug reporting for 2023-2024 shows no current infestations, rodent inspections have produced mixed results, with evidence of rat activity documented in December 2024, November 2024, January 2023, and several other inspections showing passing results. The property, built in 1910, has shown persistent challenges with basic services and maintenance, particularly regarding heat/hot water systems and pest control, warranting close monitoring of ongoing and recently opened violations.
