13 Humboldt Street, Brooklyn, NY 11206
The 8-unit, 4-story tenement building at 13 Humboldt Street in Williamsburg, built in 1931 and owned by 11-13 Humboldt Realty LLC, has experienced several recurring maintenance issues over the past few years, most notably concerning heat and hot water systems. Between 2021 and 2025, there were multiple emergency complaints about heat and hot water problems affecting the entire building, with particularly notable incidents in December 2024 and February 2025.
The building has also seen recent rodent activity, with rat sightings reported in 2025 leading to inspections that confirmed the presence of rodent activity in June and July 2025. An open violation from December 2024 requires the posting of a notice regarding the heating system keyholder in the public hall. The property has faced regulatory challenges related to unauthorized alterations, with multiple "Illegal Conversion" complaints filed, most recently in 2024, suggesting the creation of unauthorized living spaces.
This was confirmed by environmental control board violations in 2024 noting unauthorized bedroom conversions and unpermitted cellar access modifications in Apartment 1R, with an active $1,250 penalty as of 2025. Previous violations from 2021-2022 indicated issues with fire escape access and obstructions, while a 2022 inspection identified water leak and ceiling repair violations in Apartment 2R. The building's management has consistently filed bedbug reports showing no infestations between 2020 and 2025, and while several maintenance violations have been issued in recent years, many have been addressed and closed through proper remediation.
