Augrented Insights
AI summary · updated June 2026

The three-story, two-family house at 411 Sackett Street in Carroll Gardens, owned by Fred Rosenberg, has been in operation since 1899 and has experienced recurring administrative issues related to bedbug reporting compliance over the past four years. Between 2021 and 2024, the building received four Class A violations under the Housing Maintenance Code (HMC) for failing to file the required annual bedbug reports with the Department of Housing Preservation and Development (HPD). These violations, while primarily administrative in nature rather than indicative of an active pest problem, suggest a pattern of non-compliance with mandatory reporting requirements. All four violations, which occurred in April 2021, March 2022, March 2023, and most recently in April 2024, have been marked as "Close," though the current status date is not specified and no specific apartment numbers were designated on the violations. It's important to note that while these violations relate to documentation requirements rather than direct tenant health or safety concerns, their recurring nature demonstrates an ongoing oversight issue that has persisted over multiple years.
