Augrented Insights Report for 451 Seneca Avenue

451 Seneca Avenue is a 3-story, 5-unit New Law Tenement building constructed in 1930, currently owned by Tsan Cheung. The property has experienced several recurring maintenance issues, with the most recent service requests in October 2024 concerning plumbing and electrical problems (sink and outlet issues) that went uninspected due to lack of access. Two significant rat infestation incidents were documented in 2022, and as of recent inspections in 2025, the building is undergoing regular baiting treatment for rodent control.

The building has multiple open violations as of October 2024 related to public safety features, including self-closing door issues at the first-story vestibule. The property has a documented history of unauthorized alterations, with environmental control board violations from 2020 for creating unauthorized dwelling units in the cellar, though these appear to have been resolved. There have been multiple administrative violations noted in 2021 regarding the posting of safety notices for carbon monoxide detectors, smoke detectors, and gas leak procedures, which remain open.

The building's inspection history shows a pattern of rodent activity, with recent baiting efforts continuing in 2025. Historical data shows periodic requirements for bedbug reporting from 2021-2025, with no documented infestations during these periods. The property has had various building complaints and inspections from 2019 to present, including investigations into illegal conversions, compliance inspections, and construction enforcement matters, though most recent bedbug reports from 2022-2025 indicate no infestation issues.
