Augrented Insights Report for 502 West 143rd Street

The 24-unit, 6-story tenement building at 502 West 143rd Street in Hamilton Heights, managed by Alex Laszlo and constructed in 1920, has experienced recurring heat and hot water issues over the past several years, with multiple emergency complaints recorded in 2025, 2023, 2022, and 2021. The building has shown consistent problems with heating systems, evidenced by HPD investigations in March 2025, February 2025, December 2023, and December 2022, though most complaints were resolved after inspections found services had been restored.

The property has maintained a good record of responding to pest control challenges, with rodent inspections showing consistent passing results between 2018 and 2025, and no active bedbug infestations reported in recent annual filings between 2021-2025. There have been several notable violations requiring attention, particularly in 2021-2022, including problems with a broken bathtub in Apartment 2C, pest infestations, and various maintenance issues in Apartment 1B.

The building suffered a boiler-related violation in January 2023, as well as an elevator safety violation in May 2020, both resulting in Oath Violations. Recent inspections and filings indicate ongoing maintenance efforts, with the most recent rodent inspection in June 2025 passing, and no current bedbug infestations reported between November 2024 and October 2025.
