Augrented Insights Report for 313 West 21st Street

313 West 21st Street is a 6-story, 35-unit Class A residential building constructed in 1938 and currently owned by Ismo Holdings 1 LLC. The building has experienced several significant maintenance issues in recent years, with the most recent being a dust-related indoor air quality complaint from April 2025.

In late 2023, multiple housing maintenance complaints were filed regarding various issues including paint/plaster work on walls and ceilings, window pane problems, mold, and flooring concerns, though most inspections found no violations or confirmed corrections. The building experienced a heat and hot water emergency situation in October 2020, which was reportedly resolved quickly. The property has had recurring elevator issues, with three complaints between 2018 and 2024 regarding the single device elevator service, with the most recent resulting in an Oath violation served in March 2025.

There are also active ECB violations from 2022 concerning elevator maintenance and previous violations related to building maintenance and unpermitted work in 2018. The building underwent several repairs and improvements as evidenced by permit issuances between 2018-2019. Notably, the building has maintained a good record in terms of pest control, with recent bedbug reports (2023-2024) showing zero infested units, and consistent passing results on rodent inspections from 2019 through 2025.
