Augrented Insights Report for 23 South Portland Ave

23 South Portland Avenue is a 5-unit, 4-story residential building in Fort Greene, Brooklyn, constructed in 1875 and currently owned by Fred Rosenberg. The building has experienced persistent pest control challenges over the past several years, with multiple reports of rodent activity and pigeon waste documented between 2018 and 2024.

Most recently, in late 2023 and early 2024, there were health department inspections that found unsanitary conditions related to pigeon waste, and inspections in 2022 and 2024 revealed rat activity, though the most recent bedbug report from 2025 shows no current infestations. The building has also faced regulatory scrutiny regarding its bedbug reporting compliance, receiving multiple violations from 2021 to 2024 for failure to file annual reports, though the most recent 2025 filing indicates proper eradication of previously affected units. Significant building maintenance issues have been documented through various inspection reports, including three active violations related to external low-pressure inspection filings from 2018-2019, and one active building code violation related to improper storm line fittings from 2019.

The Department of Buildings has conducted multiple inspections for illegal work and drainage issues between 2018 and 2019, with varying outcomes, though no violations were recorded for certain complaints during inspection. The building has undergone several permitted repair and maintenance works between 2018 and 2020, including plumbing, electrical, and architectural improvements, suggesting ongoing efforts to address building systems and infrastructure. The property has maintained compliance with bedbug reporting requirements in recent years, with records showing all previously infested units have been successfully treated and no new infestations reported in the latest filing period.
