AI summary · updated June 2026

The two-family residence at 45 Union Avenue in Mariners Harbor, owned by Yishu He, is a relatively new two-story building constructed in 2016. The property has experienced two notable incidents in 2018, both of which raise concerns about safety and regulatory compliance. In October 2018, two complaints were filed with the Department of Buildings - one regarding a blocked egress (either locked or improperly maintained) and another concerning an alleged illegal conversion. While the egress complaint was inspected and found to have no violations on record, the investigation into the illegal conversion took a more concerning turn; an initial inspection attempt was denied access, and though a second attempt was made in December 2018, the outcome of that inspection is not specified in the available records. These incidents, particularly the egress-related complaint and the illegal conversion allegation, highlight potential safety and regulatory compliance issues, though it's worth noting that no violations were found regarding the egress complaint upon inspection. Since these incidents occurred more than five years ago, there are no recent complaints or violations on record, suggesting that the building may have maintained compliance with housing regulations in the years since these incidents.
