Augrented Insights Report for 911 St Marks Avenue

911 St. Marks Avenue is a 4-story, 4-unit residential building located in Crown Heights, Brooklyn, built in 1908 and currently owned by Sonia Ferril. The building has experienced some notable maintenance issues in recent years, most significantly with its low-pressure system and bedbug reporting compliance.

As of June 2023, there are multiple active violations related to the failure to file annual external low-pressure inspection reports from 2018 through 2022, and a violation from 2020 regarding an unfiled 2017 boiler inspection report. The building has maintained its bedbug reporting requirements as of May 2024, showing no confirmed infestations during the 2022-2023 reporting period. The property has a documented history of electrical issues, with a power outage requiring HPD intervention in October 2022, though no violations were found in that inspection.

A rodent-related complaint was filed in July 2019, though subsequent inspections in 2019 and earlier inspections in 2016-2018 showed compliance with rodent control requirements, with one failed initial inspection in August 2019 which resulted in a passing compliance inspection shortly thereafter. The building's maintenance history shows regular attention to pest control, with inspections conducted and passed in multiple years prior to 2019, suggesting ongoing management of this aspect of building maintenance. While the property has had its share of compliance issues, recent records indicate improved adherence to bedbug reporting requirements and a completed rodent inspection cycle, though the active violations regarding low-pressure system inspections remain a notable concern.
