Augrented Insights
AI summary · updated June 2026

845 Grand Street is a 6-story, 40-unit residential building constructed in 2015 in East Williamsburg, currently owned by Joel Hirsch. The building has experienced several maintenance issues over its history, with the most recent being an electrical outlet/switch complaint in October 2023, which was investigated by the Department of Housing Preservation and Development (HPD) but resulted in no violations. More concerning is the recent security-related violation from August 2024, which required both the installation of an acceptable mechanical lock for power outage security and the removal of an illegal electromagnetic locking device at the first-story public hall entrance, though this violation was certified as closed in October 2024.

The building's notable issues between 2021-2024 include a significant mold problem in 2021 (with violations issued), rodent activity documented in early 2023, and multiple violations in July 2021 regarding Apartment 5D, which had both water leak and pest infestation problems (specifically mice and roaches). During this same period, several health and safety violations were documented, including issues with hall cleanliness, improper storage of household items in common areas, and the need for gas leak procedures posting. However, the building has maintained a clean record regarding bedbug infestations since 2021, with zero units reported as infested in the most recent 2025 filings. While the building has faced numerous maintenance challenges, it has consistently addressed and closed violations as required, with no recent history of recurring infestations or unresolved safety concerns.

Serious violations last 1–2 years

Building size

Number of apartments
