Augrented Insights Report for 21 West 131st Street

21 West 131st Street, a 5-story, 10-unit old-law tenement building in Harlem, has experienced persistent maintenance challenges, particularly regarding pest control and building systems. Most recently, in January 2025, there is an open HPD complaint regarding unsanitary conditions related to pests, following a similar issue in December 2024 that was marked as closed after verification of corrections.

The building has documented multiple rodent-related incidents from 2024 through 2025, with inspections showing varying results between "Passed" and "Rat Activity." A significant heat and hot water emergency complaint was resolved in December 2024, and earlier violations in 2024 included mold issues in apartment 5R, problems with doors/windows, and general unsanitary conditions. The building's history shows recurring concerns about basic services and maintenance, including multiple complaints and violations related to boiler issues in 2019-2020, though inspectors repeatedly faced access difficulties.

Several code violations were addressed and closed in 2024, including issues with fire retardant material and mold in the 5th-floor bathroom. The property has maintained an active bedbug monitoring program from 2019 to present, with all reports showing zero infested units or eradication efforts needed. While the building has had numerous maintenance issues over the years, there is evidence of ongoing compliance efforts, as demonstrated by recent rodent inspections in 2025, which show a mix of pass and fails, indicating ongoing pest management challenges.
