723 East 5th Street, Brooklyn, NY 11218

723 East 5th Street is a 4-story, 21-unit residential tenement building located in Kensington, built in 1930 and currently owned by Steven Muller. The property has experienced recurring maintenance issues in recent months, with multiple heating and hot water outages reported between January and February 2025, affecting both individual units and the entire building. More recently, in April 2025, complaints have emerged regarding ceiling paint and plaster issues, as well as unsanitary conditions related to mold.

The building underwent an inspection in October 2024 that revealed several violations in Apartment 2B, including pest infestations (mice and roaches), damaged plaster surfaces, defective smoke and carbon monoxide detectors, and a disturbance involving drilled-through walls. Infrastructure problems have persisted, with plumbing issues reported in late 2024, though inspectors were often unable to gain access for thorough inspections. The building's recent history shows some improvements in certain areas, such as a passed rodent inspection in September 2024, following earlier concerns in 2017.

The property has maintained a clean bedbug record over the past several years, with no reported infestations between 2020 and 2025. Historical records from 2018 indicate some electrical concerns and unauthorized work, though no violations were warranted at the time of inspection. The building's maintenance code violations from October 2024 were generally addressed, with most being certified as corrected by the end of that month. An illegal conversion complaint was filed in 2022 but was closed due to inability to gain access for inspection.
