Augrented Insights Report for 237 East 121st Street

The four-story, 12-unit building at 237 East 121st Street in East Harlem, owned by Nelson Erazo and constructed in 1920, has experienced ongoing plumbing issues, with significant consolidation of complaints in July 2024 involving toilets, sinks, bathtubs/showers, and water supply problems across multiple units. The building has a history of heating and water system challenges, with multiple violations and complaints related to water supply, including emergencies in 2020 and 2021 that required HPD intervention. The property has faced several maintenance issues over the years, including a regulated bedbug report requirement violation in April 2024, though recent inspections indicate no current infestations.

Between 2021 and 2023, there were persistent violations related to water leaks, building safety, and maintenance issues, particularly affecting the common areas and unit 2B. Notably, there are multiple active Department of Buildings violations from 2019 through 2023 regarding failure to file required inspections, including several for low-pressure inspection requirements. The building underwent rodent control inspections from 2018 to 2025, with most recent inspections in 2024-2025 showing "Passed" results except for a failed compliance inspection in 2022 due to unspecified reasons.

There have been several concerning patterns in the building's history, including multiple illegal conversion complaints between 2018-2019, though these complaints were frequently marked as "Inspector Unable to Gain Access" during inspections. The most pressing current concerns involve the active Department of Buildings violations regarding inspection compliance, with penalties totaling $10,000 for failure to provide unobstructed exit passageways and various other maintenance violations. Recent complaints and inspection results suggest some improvement in building conditions, particularly regarding pest control, as evidenced by the passed rodent inspections and the 2024 bedbug reporting showing zero infestation cases.
