673 Madison Avenue, Manhattan, NY 10065

The five-story, two-family house at 673 Madison Avenue, built in 1871, has experienced significant maintenance and safety issues in recent years, particularly in mid-2025. Recent complaints have included multiple emergency-level issues such as a non-functioning carbon monoxide detector, unsanitary mold conditions, problems with doors/windows, and concerns about the sprinkler system.

There is currently an active plumbing-related complaint, while another plumbing issue from September 2021 was previously investigated without violations being found. The building has a troubling history of safety violations related to occupancy issues, with multiple citations in 2019-2021 regarding illegal transient use of Apartment 5E, lack of required means of egress, and missing sprinkler systems, though these were ultimately resolved. The property has undergone several pest-related challenges, with recent rodent activity documented in September 2023, and bait applied during inspections later that year, though previous inspections had shown the building passing compliance checks.

A food poisoning complaint was filed in September 2023, which the Health Department determined was an isolated incident, while a rodent complaint from July 2022 was investigated and found to have no violations. There were also several violations recorded between 2019-2021 regarding failure to maintain building compliance and respond to correction orders, primarily related to safety equipment and systems. The building's management has faced multiple fines and violation notices during this period, including penalties for failure to maintain proper safety systems and for violations of occupancy regulations, though some of these violations have since been resolved or dismissed.
