AI summary · updated June 2026

This three-story, three-unit residential building located at 1275 Herkimer Street in Bedford-Stuyvesant, owned by James Mulligan, is a 1920 structure classified as an "Old Law Tenement." Since at least 2021, the building has been subject to recurring Housing Maintenance Code violations related to the failure to file annual bedbug reports with the Department of Housing Preservation and Development (HPD), with the most recent violation occurring in April 2024. These violations, which are classified as "Class A" requiring timely correction, suggest an ongoing compliance issue with HPD reporting requirements.

The building's inspection history shows two completed rodent inspections in 2014 and 2019, both of which passed, indicating no significant rodent issues were present at those times. While the passing rodent inspections are a positive note in the building's history, the pattern of open bedbug report violations over the past several years represents the most notable current issue affecting the property, as these violations pertain to required public health reporting standards.
