Augrented Insights Report for 321 West 100th Street

The 5-story, 4-unit residential building at 321 West 100th Street, built in 1901 and owned by 321 W 100 Street Tenants Corp, has experienced several notable issues in recent years. Most concerning are the open Housing Maintenance Code violations from 2022-2024 related to failure to file annual bedbug reports, and two significant Environmental Control Board violations from March 2024 involving an obstructed emergency exit and unauthorized construction of a large rear yard structure.

The building has also had recurring rodent issues, with rat activity documented in 2023 and an open violation as of 2024, though it passed inspections in 2019, 2020, and 2022-2023. The building has experienced an electrical power outage in March 2019, though no violations were found following the complaint investigation.

Multiple complaints about unauthorized work in the building were filed between 2021-2024, with varying outcomes for inspector access. A cluster of Housing Maintenance Code violations were resolved in 2019-2020 related to proper safety notice postings regarding gas leak procedures, smoke detector requirements, carbon monoxide detectors, and the building's registration information. The building's bedbug reporting history from 2017-2020 indicates no infestations were reported during those periods, with all filed reports showing zero infested, eradicated, or re-infested units.
