Augrented Insights Report for 1721 Cornelia Street

The 6-unit, 3-story tenement building at 1721 Cornelia Street in Ridgewood, owned by Tien Nguyen, has experienced persistent pest management challenges over the past several years. From late 2019 through 2021, there were multiple Housing Preservation and Development (HPD) complaints regarding pest (specifically rodent and potential bedbug) issues, with several violations issued during inspections in 2021.

More recently, there have been ongoing rodent activity concerns, with multiple bait application interventions documented between September and December 2024, and rat activity confirmed during inspections in September and November 2024. The building has several open violations of particular note: Two annual bedbug reporting violations from 2023 and 2024 that remain unresolved, and a violation related to the building's heating system (boiler inspection) that remains active since November 2019.

Previous violations demonstrate a pattern of maintenance issues, including a 2023 correction regarding self-closing doors at the bulkhead, and various repairs needed in apartment 1L in 2021 including floor repair, plaster work, and replacement of a defective carbon monoxide detector. The building has also undergone regular rodent control measures, with bait applied consistently throughout late 2024, suggesting ongoing efforts to address pest management challenges, though their effectiveness remains variable based on inspection results.
