121 St Marks Place, Brooklyn, NY 11217

121 St Marks Place is a three-story, three-unit old law tenement building constructed in 1910, currently under the ownership of 121 St Marks Place Llc. The building has experienced significant maintenance issues in 2022, with multiple complaints and violations documented between March and April of that year, including problems with flooring, walls, ceilings, a refrigerator, steam pipes, and pest control that were all investigated but notably resulted in no violations being issued. An interesting pattern emerged in 2022 with a cluster of complaints filed on April 5th concerning various maintenance issues, all of which were subsequently closed without violations.

In the following months, the building underwent inspections for bedbugs, with no reported infestations during the 2021-2024 reporting periods. More recently, in 2025, there have been serious structural concerns regarding the building's facade and cornice, documented in a violation from May 29th noting vertical stress cracks, split windowsills, and deteriorated cornice elements creating potential safety hazards. A sidewalk shed was also noted to have been erected for safety purposes, though the disposition of this violation was dismissed.

Notably, in May 2025, the building was placed under structural monitoring, indicating significant ongoing concerns about its condition. The building's history includes various rodent inspections between 2011 and 2018, with some indicating rat activity in 2011 and early 2018, though more recent rodent inspections show no current issues. While the building has maintained compliance with bedbug reporting requirements, the recent structural violations and monitoring status have raised concerning questions about the building's current condition.
