90 South 1st Street, Brooklyn, NY 11249

The five-story residential building at 90 South 1st Street in Williamsburg, owned by Ben Schlesinger and constructed in 2011, has experienced several notable events since its completion, with the most significant being an illegal conversion incident in 2020-2021. This case, which was resolved with a $625 penalty, involved unauthorized modifications to the cellar level where full-height partitions and new bathroom facilities were installed without proper permits, resulting in occupancy concerns beyond the building's authorized eight-family configuration.

From 2019 to the present, the building has shown consistent compliance with bedbug reporting requirements, with no reported infestations in any of the five annual filings between 2020 and 2025. The building has experienced some infrastructure issues, most notably a heat and hot water complaint in December 2019 that could not be investigated due to lack of access. While the building was issued several Housing Maintenance Code violations between 2021 and 2024 regarding annual bedbug report filings, these have all been closed.

A rodent inspection conducted in April 2019 resulted in a passing grade. More recently, the building's bedbug filing for the period 2023-2024 reported zero infested units, and the property has maintained a clean record since the bedbug reporting requirements were initially established. The building's history suggests improved maintenance compliance in recent years, particularly regarding pest control measures, though the 2020 illegal conversion incident remains a significant historical event.
