Augrented Insights Report for 520 Henry Street

520 Henry Street is a 7-unit, 4-story residential building in Carroll Gardens, built in 1931 and currently owned by Ariey Nusbaum. The property has experienced recurring heat and hot water issues, with emergency complaints filed in both November and December 2024 affecting the entire building, leading to open violations regarding inadequate heat supply and water issues above 130 degrees.

The most recent health concerns include an active infestation of mice in Apartment 3, as well as multiple safety violations including a missing smoke detector and carbon monoxide detector in that unit. The building's maintenance record shows persistent boiler-related issues, with open violations as of June 2023 for failure to file external low pressure inspections from 2018-2021, and a problematic history with heating system access, evidenced by locked doors during HPD inspections in both November and December 2024.

The property has a documented pattern of pest control challenges, particularly in 2018 when multiple rodent activity reports were filed, though subsequent inspections in 2018 and 2024 showed compliance. Historical records from 2019-2020 indicate possible food safety concerns with the presence of rodents, insects, and sanitation issues in food establishments, though these complaints were closed. The building has faced various regulatory compliance challenges, including a complaint about work without a permit in 2025 that was referred to the Department of Consumer Affairs, and an active Environmental Control Board violation from 2019 related to incomplete boiler inspection filings with a penalty of $3,125.
