Augrented Insights Report for 31 East 21st Street

31 East 21st Street is a 6-story, 49-unit residential building constructed in 1931, currently owned by Francisco Dela Cruz Pena. The building has experienced recurring issues with heat and hot water during 2025, with multiple emergency complaints filed between April and May 2025, affecting both entire building and individual apartments. The property has also faced significant maintenance challenges, including active rodent infestation problems, as evidenced by multiple bait application inspections throughout 2025 and inspection results indicating rat activity in October 2024 and February 2025.

Apartment 4C has numerous outstanding violations from September 2024, including issues with pests (roaches and mice), defective smoke and carbon monoxide detectors, a broken intercom system, and various plumbing and maintenance problems affecting the bathroom and kitchen. The building's infrastructure has been a concern, particularly regarding the elevator system. There have been multiple elevator-related complaints between 2018 and 2025, including a "Single Device on Property/No Alternate Service" violation in June 2025.

Other significant historical issues include a boiler violation in 2021, illegal conversion complaints in 2020-2021, and various compliance inspection failures. Recent maintenance actions have included multiple plumbing-related complaints in mid-2025, covering sink and bathtub issues, and building-wide pest control efforts. The property has maintained an active response to bedbug infestations, though recent filings from 2022-2024 indicate minimal cases, with only one infested unit reported in 2022. The building's owners have obtained several permits for work on the property between 2018-2019, including plumbing and electrical modifications, though the specific nature of these improvements is not detailed in the records provided.
