Augrented Insights Report for 1523 Undercliff Avenue

1523 Undercliff Avenue is an 8-story, 15-unit residential building constructed in 2011 in the Morris Heights neighborhood, currently owned by Adam Mermelstien. The property has experienced recurring maintenance issues, particularly with the elevator system, which has generated multiple complaints between 2021 and 2024 about being out of service with no alternate access, resulting in several ECB violations and penalties totaling $7,437 in 2024 alone. Recent service calls in 2025 have included issues with an electric/gas range and heat/hot water systems.

The building has faced significant habitability challenges, including a December 2024 heat/hot water outage affecting the entire building, multiple pest-related complaints (including roaches and mice) in late 2024, and various plumbing issues. Apartment 5C has been the focus of multiple violations as of October 2024, including pest infestations (bedbugs, mice, roaches), issues with self-closing doors, and plumbing problems, though some of these violations have been certified as corrected by December 2024. The building's systems have shown ongoing maintenance needs, with open violations regarding safety equipment such as smoke and carbon monoxide detectors. While recent bedbug reports from 2025 show no active infestations, the building's history suggests periodic pest management challenges.

The property has also faced documentation compliance issues, with active DOB violations recorded in 2020 and 2023 for failure to file inspection reports. The building's maintenance history shows a pattern of both reactive and preventive maintenance, with some issues being promptly addressed while others remain ongoing. Recent inspections have demonstrated some improvements, with a passed rodent inspection in December 2024, though an initial rat activity report was recorded in October 2024. The property has maintained regular elevator service between August 2024 and the current date, with no recent elevator-related violations recorded since February 2025, suggesting improved maintenance of this critical building system as of mid-2025.
