Augrented Insights Report for 21 Arden Street

Located in Inwood, 21 Arden Street is a 5-story, 16-unit building constructed in 1914 and currently owned by 21 Arden Owners Hdfc. The building has experienced recurring heating and hot water issues, with four separate emergency complaints documented between July 2022 and December 2023, though inspections did not result in violations. More concerning are two recently achieved Class C violations from April 2024 related to door safety in apartments 1C and 2A, and a 2018 water leak complaint that remains open as of October 2023.

The property has maintained good pest control practices, with all bedbug reports from 2020-2024 showing zero infestation cases. Recent inspections and violations suggest active maintenance engagement, though with some lapses - including the 2023-2024 violations for failure to file external low-pressure inspections. The building underwent significant construction work in 2019-2021, which generated multiple construction safety compliance complaints and several Environmental Control Board violations, particularly related to safety protocols and equipment.

All construction-related violations appear to have been resolved, including issues with scaffold safety and electrical equipment. The building has consistently passed rodent inspections since 2020, showing improved pest management, though earlier inspections in 2017-2019 had some failures that were corrected. Recent permit activity and monthly heat and hot water service requests indicate ongoing maintenance and system updates, though the persistent nature of heating system complaints suggests this remains an area requiring regular monitoring.
