7123 4th Avenue, Brooklyn, NY 11209
7123 4th Avenue is a four-story, 36-unit New Law Tenement building in Bay Ridge, owned by Cynthia Avellino and constructed in 1950. The building has experienced several significant maintenance issues in recent years, most notably a heat and hot water emergency affecting the entire building in December 2024, which was subsequently resolved. There have been two plumbing-related complaints (toilet issues) in October 2021, which could not be inspected due to access issues.
The Department of Health and Mental Hygiene is currently investigating a rodent problem reported in April 2020 that remains open as of October 2023. The building underwent a period of construction activity between 2018-2022 that generated multiple complaints and violations, including safety concerns about falling debris, scaffold issues, and unauthorized work. Several stop work orders were issued and subsequently rescinded, and there were multiple citations for failing to safeguard persons and property during construction. The building has maintained a clean record regarding bedbug infestations, with annual reports since 2019 showing zero infested units.
Recent permit filings from 2018 through 2021 indicate regular maintenance and improvement work being conducted, with the most recent bedbug report from January 2025 showing no new infestations in the previous year. The property's violation history shows several resolved Environmental Control Board (ECB) violations from 2018-2019 related to construction safety and permit compliance, with some penalties applied during that period. Two active violations remain on record from January 2022 regarding work stoppage due to applicant withdrawal, which are pending resolution. The building's maintenance record from 2019 to present shows a pattern of addressing heating systems, plumbing issues, and construction-related concerns, with varying levels of access for inspection and resolution by authorities.
