Augrented Insights Report

The 27-unit, 4-story apartment building at 20 Cedar Street (1025 Post Street) was constructed in 1914 and has experienced several significant maintenance and safety issues in recent years. Most notably, there is an ongoing problem with the building's elevator, which has been frequently disabled throughout 2023-2024, creating accessibility challenges for disabled residents. The building has also faced multiple fire alarm system violations in 2023, with three alarms requiring correction between August and November 2023, and a sleeping area requirement violation issued in December 2023.

Recent improvements to the building have focused on individual unit upgrades, with several apartments (Units 21, 22, 26, and 27) undergoing kitchen and bathroom renovations, electrical upgrades, and washer/dryer installations between 2021-2022. The building's infrastructure has seen significant work, including the replacement of multiple water heaters in 2022 and sewer lateral replacement. However, there have been concerning recent violations regarding interior conditions, including issues with damaged ceilings, lead paint notifications, and smoke detector requirements filed in January 2024, all of which were subsequently abated by March 2024.

Historical complaints dating back to the late 1990s-2008 indicate recurring issues with basic services such as hot water supply, electrical problems, and ventilation concerns, though many of these older problems appear to have been resolved. The property has undergone various attempted improvements, including a withdrawn proposal in 2020 to add three accessory dwelling units (ADUs) at the ground level. Recent maintenance work has focused on individual unit rehabilitation, while major building systems such as the fire alarm system continue to require attention. The building's management has made efforts to address maintenance issues as they arise, though the persistent problems with the elevator system and recurring fire alarm violations suggest ongoing challenges with building systems maintenance and resident accessibility.
