Augrented Insights Report for 231 East 21st Street

231 East 21st Street is a 6-story, 24-unit residential building located in Gramercy, constructed in 1920 and currently owned by 21st Owner LLC. The property has experienced recurring heat and hot water issues, with complaints filed in December 2022 and February 2025, though HPD could not access units for inspection in 2025. Significant maintenance concerns emerged during 2022-2023, including indoor air quality issues related to construction dust and lead, multiple emergency door/window complaints, and safety concerns regarding window guards.

The building underwent substantial electrical work in 2022, resulting in ECB violations for various electrical maintenance issues, though these were resolved with penalties totaling $2,000. A series of Housing Maintenance Code violations were recorded in 2022, particularly in September, including multiple open violations related to safety requirements and signage that remain unresolved. The property has experienced persistent rodent activity, with the most recent rodent inspections in 2025 showing rat activity. While the building's bedbug history appears relatively clean, with no reported infestations in the past six years, recent building conditions have raised concerns.

The building has documented multiple safety-related complaints in 2024, including issues with smoke and carbon monoxide detectors, and door problems. The property has undergone various emergency repairs and inspections, particularly related to heating systems, door issues, and safety compliance. A number of violations related to construction work and improper materials were recorded in 2024, though many were subsequently addressed and certified as corrected. The building's maintenance history shows ongoing challenges with system maintenance and prompt response to resident complaints, particularly regarding access for inspections and timely resolution of heating issues.
