Augrented Insights Report for 346 21st Street

The 8-unit, 4-story building at 346 21st Street in Sunset Park, owned by Dmitri Routgauzer, has experienced several significant maintenance and safety issues in recent years. Most notably, there have been recurring problems with heat and hot water, with emergency complaints logged in January 2025 and December 2023, though inspections found heat and hot water had been restored by the time of response. The building has also faced plumbing issues, including water supply problems in May 2024, and violations related to mold and ceiling conditions.

Safety concerns have emerged, with a 2025 emergency complaint regarding a broken window guard, and multiple violations regarding self-closing doors and public hall obstructions in 2024. Most concerning is an active Environmental Control Board violation from May 2024 related to deteriorated beams in Apartment 2R, with a corresponding Department of Buildings violation regarding open ceiling conditions in May 2024. The building's maintenance history reveals additional concerns, including multiple violations regarding life safety systems such as smoke and carbon monoxide detectors in Units 2L and 2R.

There have been ongoing issues with the building's exterior and structural systems, as evidenced by complaints in May 2024 regarding building shaking and structural stability, though these were ultimately dismissed. The property has passed recent rodent inspections, and there have been no documented bedbug infestations in the past five years. There are also outstanding Department of Buildings violations for failure to file annual boiler and external low pressure inspection reports, dating back to 2020 and 2024 respectively. While some historical complaints from 2019 regarding construction work and notice distribution were resolved, the building continues to experience maintenance challenges that affect resident comfort and safety.
