403 Union Street, Brooklyn, NY 11231

403 Union Street is a three-story, four-unit residential building located in Carroll Gardens and owned by Margaret McGuire. Built in 1920 and classified as a HERETOFORE CONVERTED CLASS A building, this property has experienced several maintenance issues over the past five years.

Most notably, in late 2018, there were significant heating and hot water system failures that affected both individual apartments and the entire building, though these issues were reportedly resolved following HPD intervention. In 2021, the building faced rodent control challenges, with multiple rat sightings reported through 311 complaints, though inspections conducted by the Department of Health and Mental Hygiene found only minor violations, and a subsequent inspection in September 2021 passed. The building's maintenance record shows consistent compliance with bedbug reporting requirements, with all annual filings from 2019 through 2025 indicating zero infested units, zero eradicated units, and zero re-infested units.

A 2023 violation was issued regarding the filing of the annual bedbug report, though this appears to have been resolved with subsequent filings showing proper documentation. The property's most recent inspection records and complaint history suggest improved conditions, with no significant ongoing maintenance issues reported as of 2025. The building's heating system issues from 2018, while notable, appear to have been an isolated incident based on available records, and the property has maintained a proactive approach to pest management through regular reporting and inspections.
