Augrented Insights Report for 121-20 Liberty Avenue

121-20 Liberty Avenue is a two-family home located in Richmond Hill, built in 1931 and currently owned by Mayhongwei Yin. The property has experienced notable recurring maintenance issues, particularly in late 2024 and early 2025, with multiple reports of electrical problems including a significant power outage crisis across multiple units in December 2024 which resulted in issued violations, and a heat/hot water complaint in February 2025 that could not be verified due to lack of access for inspection.

Earlier in 2024, violations were identified regarding pest infestations in Apartment 2C, specifically citing issues with both mice and roaches, along with problems including a defective carbon monoxide detector. The building had multiple safety violations documented between April and December 2023 including issues with an electrical outlet and a broken light fixture in the public hallway.

The property has undergone regular inspections, passing numerous rodent inspections throughout 2023-2024, though there were some compliance issues noted regarding external low-pressure inspection filings in 2023 that were eventually dismissed. Two illegal conversion complaints were filed in 2024-2025, though inspectors were unable to gain access during their final attempts to investigate these claims. While several maintenance code violations have been resolved since 2023, including garbage receptacle requirements and various equipment repairs, the building continues to experience periodic maintenance issues that impact resident comfort and safety, particularly relating to heat and electrical systems.
