121 Wythe Avenue, Brooklyn, NY 11249

121 Wythe Avenue is a three-story, four-unit residential building located in Williamsburg, Brooklyn, built in 1910 and currently owned by Andrzej Olszewski. The building has experienced several notable events over the past few years, with the most recent being March 2023 violations related to bedbug reporting requirements, though these violations have since been resolved.

Between 2018 and 2019, the property was involved in multiple Environmental Control Board (ECB) violations, primarily concerning failure to comply with commissioner's orders regarding work without permits, with penalties totaling $6,625, though records indicate these violations were eventually resolved with no outstanding balances. A stop work order was issued in February 2019 regarding construction activities, but this was fully rescinded by May 2019.

The building's permit history shows multiple work permits were issued in 2018-2020, including two in October 2020 and one in late August 2018, covering electrical and plumbing work. Notably, the property has maintained a consistent record of bedbug monitoring and reporting, with the most recent filing in July 2025 indicating no infestations in the past two years (2023-2024) and previous years showing similar results of zero infested or re-infested dwelling units. The building's management has demonstrated compliance with bedbug reporting requirements since 2019, submitting timely reports and maintaining records of eradication efforts, with no documented history of bedbug infestations in the past six reporting periods.
