Augrented Insights Report for 89 Porter Avenue

89 Porter Avenue is a 4-story, 45-unit residential building in East Williamsburg, constructed in 1931 and currently owned by John McDonald. The property has experienced persistent heating and hot water issues over the past several years, with multiple emergency complaints filed between 2022 and 2025, including a notable cluster of ten complaints between July and August 2024 alone. These issues have resulted in several Housing Maintenance Code violations, primarily related to inadequate hot water supply in various bathrooms, though some violations were eventually resolved following inspections.

The building has also faced elevator-related problems, with multiple violations documented in late 2023 regarding service elevator equipment, including a December violation for being out of service and creating hazardous conditions, which incurred fines of $3,125. Recent inspections and complaints have highlighted additional maintenance concerns, particularly regarding the building's heating system and water infrastructure, with violations noted for corroded gas piping and water-related issues in the boiler room. The property has maintained active bedbug reporting compliance, with no infestations reported in the most recent filing period (November 2022 to October 2023), following a previous incident in 2020-2021 involving four units.

Rodent activity has been a recurring issue, with multiple inspections between 2022 and 2025 showing evidence of rat activity, though some inspections also passed successfully. The building's management has been cited for various regulatory compliance issues, including failure to properly file annual reports and maintain equipment as per code requirements, with some violations still listed as active. While there have been several instances of heat and hot water complaints, HPD inspections often found conditions improved by the time of inspection, though not always for all units. The most recent complaints in January 2025 again involved heat and hot water issues, though HPD was unable to gain access for verification.
