AI summary · updated June 2026

40 West 71st Street is a 4-story, 10-unit residential building located in Manhattan's Upper West Side, constructed in 1887 and currently owned by 40 West 71st St Corp. The building has experienced only one significant maintenance issue in recent years, which occurred in August 2018 when both the Department of Housing Preservation and Development and Housing Maintenance Code received complaints regarding cooking gas, though inspectors were unable to gain access to verify the conditions. Since then, there have been no recorded housing maintenance complaints related to this or any other issues.

The building's pest control record is notably clean; recent bedbug reporting from December 2024 through 2019 shows zero infested units or related issues. The property has maintained good results in rodent inspections overall, with the most recent inspections in 2024, 2023, 2022, 2019, and 2018 all passing successfully. However, the building did experience two instances of rat activity in 2017 (February and April), which may have affected resident comfort at that time, though subsequent inspections indicate the issues were resolved. The consistent passing of rodent inspections in recent years suggests effective ongoing pest management practices are in place.

What's driving this score
