109 St Marks Avenue, Brooklyn, NY 11217

109 St Marks Avenue is a three-story, three-unit residential building constructed in 1886 in the Prospect Heights neighborhood, currently owned by 109 Owners Inc. The building has a concerning pattern of open Housing Maintenance Code violations related to bedbug reporting requirements, with four consecutive violations from 2021 through 2024, indicating persistent non-compliance with mandatory annual bedbug report filings as required by HPD regulations.

Most recently, in June 2025, a Department of Buildings violation was issued requiring the installation of approximately 20 linear feet of sidewalk shed to safeguard public access and protect property, though this violation remains active with no recorded disposition to date. The building's history shows regular rodent inspections in 2017 and 2018, both of which were passed, suggesting no significant rodent problems during that period.

However, the persistent bedbug reporting violations over multiple years and the recent sidewalk shed requirement raise questions about building maintenance practices. While the bedbug reporting violations specifically relate to administrative compliance rather than active infestations, the recurring nature of these violations suggests potential challenges in management responsiveness to building codes. The property's age and relatively small size (three units) are typical for the Prospect Heights neighborhood, though the building has transitioned from its original classification to a "Heretofore Converted Class B" designation, indicating some form of conversion from its original configuration.
