Augrented Insights Report for 171 4th Avenue

171 4th Avenue in Park Slope is a 4-story old law tenement building currently owned by Winston Morris. The property has experienced recurring issues with rodent infestations, with the most recent inspections in 2024 showing active rat activity in both September and October, following previous sightings in July 2023 and December 2024. There are also ongoing concerns about compliance with bedbug reporting requirements, with multiple open violations from 2022-2024 related to the failure to file annual bedbug reports as required by Housing Maintenance Code.

The building has faced several heating and hot water issues, most notably an emergency complaint in November 2023 regarding lack of heat/hot water in the entire building, though inspectors were unable to gain access for verification. The property is currently facing multiple active Environmental Control Board violations related to construction equipment and safety concerns. These include violations for expired construction equipment permits, a cracked sidewalk creating trip hazards, and issues with construction fence maintenance, with penalties totaling over $10,000.

Recent inspections have repeatedly found violations related to construction safety, including debris netting and fence maintenance issues. The building's history includes several complaints about garbage/recycling storage, though the most recent HPD inspection in June 2025 did not find violations. The property underwent some form of demolition notification process in 2018, with initial notifications accepted, and has maintained a pattern of rodent-related complaints and violations over the past several years, suggesting ongoing pest control challenges.
