Augrented Insights Report for 100 Lefferts Avenue

The 6-story, 60-unit building at 100 Lefferts Avenue in Prospect-Lefferts Gardens, owned by Margaret Brunn and constructed in 1929, is facing multiple ongoing maintenance issues as of mid-2025. Most notably, there are still unresolved complaints regarding heat and hot water for the entire building, water leaks, and wall paint/plaster problems that were reported in April 2025. The building has experienced recurring electrical issues throughout 2025, including power outage complaints and no lighting conditions, though some of these complaints have been closed after inspections.

There are also significant pest control challenges, with multiple properties in the building (1E, 6G, and 5J) identified as having rodent and cockroach infestations in recent violations from late 2024. The property has a history of elevator service interruptions, with multiple complaints about "Single Device on Property/No Alternate Service" between 2019 and 2025. Recent inspections in 2024 and 2025 showed compliance with rodent inspections, though a rat activity notice from October 2023 remains notable.

The building has also had various maintenance violations related to water leaks, flooring issues, and HVAC systems, with an active violation regarding failure to display energy efficiency scores from 2021. While bedbug infestations were reported in previous years (2019-2022), recent filings indicate no occurrences in the last two reporting periods (2023-2024). The property has had several Department of Buildings violations and requirements for external low-pressure inspections, with active violations still pending resolution as of 2023-2024.
