Augrented Insights Report for 503 Union Avenue

503 Union Avenue is a 4-story, 23-unit residential building located in Williamsburg, Brooklyn, built in 1930 and currently owned by David Jacobowitz. The building has experienced several significant incidents over recent years, with the most pressing being a pattern of elevator-related issues and administrative compliance matters.

Between 2018 and 2022, there were multiple complaints and violations related to the elevator system, though inspections consistently found no violations warranted. The building faced two instances of failing to file required energy benchmarking reports in 2019 and 2022, though both violations were dismissed or resolved.

The property has also shown a commitment to pest management, with bedbug infestation reports showing zero affected units in the annual filings from 2021 through 2024, despite earlier violations in 2021 and 2022 regarding the late filing of required bedbug reports. An environmental control board violation was recorded in 2018 regarding inadequate housekeeping during construction work on the roof, but this was resolved without any penalties. The building underwent several permitted improvements between 2018 and 2019, including work classified as alteration, equipment, and plumbing-related, with all permits being properly issued and recorded.
