Augrented Insights Report for 21 East 21st Street

21 East 21st Street is a 6-story, 41-unit Class A apartment building constructed in 1938, currently owned by 21 East 21 Street Partners LLC. The building has experienced numerous maintenance issues in recent years, with particularly concerning patterns emerging in 2024-2025. Multiple complaints regarding water supply problems, including two uncompleted inspections in 2025, suggest ongoing plumbing challenges.

The building has also faced pest management challenges, with multiple unsanitary condition complaints in April 2025 and 2024-2025, including violations related to mold and pests. Heating and hot water issues were reported in April 2025, with HPD inspectors unable to gain access to verify conditions. Additional maintenance concerns have been documented through 311 service requests and Housing Maintenance Code Complaints in 2025, including issues with cupboards, flooring, appliances, and door/window problems. The building's history shows recurring elevator and boiler issues from 2019-2020, with multiple complaints about elevator service and a 2019 boiler violation regarding relief valve and other mechanical components.

Environmental Control Board violations from 2019-2020 indicate problems with elevator safety features and monitoring systems. Recent rodent activity has been consistently documented through inspections, with the most recent findings showing rat activity in February 2024. The building has had documented bedbug cases, with one unit reported infested in the 2023-2024 period, though previous infestations from 2019-2022 appear to have been resolved. Compliance inspections have shown mixed results, with particular concern about the building's heating system access and maintenance in recent months.
