Augrented Insights Report for 23 East 20th Street

23 East 20th Street is an 8-story, 7-unit residential building constructed in 1901, currently owned by Ralph Westerhoff. The building has experienced several maintenance and safety issues in recent years, with the most pressing concerns centering around plumbing systems, water supply problems, and mold issues. Most notably, there was an unresolvable plumbing inspection in October 2024, and multiple plumbing-related service requests between 2023-2024.

Apartment 2 has documented open violations from 2022 regarding multiple maintenance concerns, including leaky faucets, bathroom plumbing connections, window frame repair needs, water leak issues, and floor problems, all of which remain unresolved as of 2025. The building's safety systems have also received attention, with inspections revealing issues with smoke detectors in 2024 that required emergency attention. From 2021-2024, there have been significant environmental control violations regarding the building facade, including active penalties totaling $42,500 related to unsafe conditions and failure to maintain exterior building elements.

There have also been multiple Housing Maintenance Code complaints across various dates in 2023-2024 regarding unsanitary conditions, door/window issues, and general maintenance problems, though most were closed without violations being issued. The building has maintained an up-to-date bedbug reporting record from 2022-2025 showing no infestations, and completed four rodent inspections from 2010-2014, all of which passed. Recent reports from 2025 indicate no active bedbug or rodent issues, though multiple open violations regarding plumbing and facade maintenance remain on record with the Department of Buildings and Environmental Control Board.
