129 Guernsey Street, Brooklyn, NY 11222
129 Guernsey Street is a four-story, eight-unit New Law tenement building constructed in 1930, currently owned by Danuta Roszkowska.
The property has had minimal maintenance issues, with only one notable Department of Buildings violation on record in April 2023 regarding the failure to file the 2022 external low pressure inspection report, though this violation was subsequently dismissed in December 2024.
The building's bedbug reporting history, covering the period from 2018 through 2025, shows an exemplary record with zero cases of infestation, eradication, or re-infestation reported across all eight annual filing periods - this consistent lack of pest issues is particularly noteworthy and paints a positive picture of the building's maintenance and hygiene standards. The most recent bedbug report from June 2025, covering the 2023-2024 period, similarly indicated no infestation problems, continuing the building's clean record in this regard.
