AI summary · updated June 2026

The two-family, two-story building at 310 Sumpter Street in Bedford-Stuyvesant, owned by Shawn Bolding, has experienced several maintenance issues over the past two years, with the most recent problems emerging in late 2024 including a power outage in September 2024. There have been recurring water-related issues, with documented complaints about slow leaks and damp spots in late 2023, as well as electrical problems including lighting issues in December 2023. A significant pattern of maintenance concerns is evident, with multiple complaints about garbage and recycling storage in the basement area. A comprehensive inspection in September 2024 revealed several open violations, including problems with self-closing doors in the basement and first-story areas, as well as encumbrances of household items in various locations throughout the building.

The building's history shows regular bedbug reporting compliance between 2021-2024, with no reported infestations during the most recent filing periods (November 2023 - October 2024 and November 2022 - October 2023). While many previous violations were successfully addressed and closed, including bedbug report compliance, the current open violations from September 2024 regarding door hardware and storage issues suggest ongoing maintenance challenges. The property has maintained a two-unit configuration since its construction in 1924 as a New Law Tenement.
