Augrented Insights Report for 6324 20th Avenue

6324 20th Avenue is a 4-story, 9-unit residential building constructed in 1930, currently owned by John Lau and classified as a "New Law Tenement." The building has seen several notable events over the past few years, with the most recent issues occurring in 2024 involving appliance problems (electric/gas range) that were promptly addressed and closed by the HPD. The building was inspected for bedbug compliance in 2024, 2023, and 2021, receiving violations in each of the past three years for failing to file the required annual bedbug reports, though subsequent filings from 2025 and 2024 show no evidence of infestation.

Between 2018-2019, there was significant activity related to the building's first-floor commercial space, including multiple complaints and violations regarding illegal occupancy as an adult establishment and unauthorized construction work. These violations were resolved with various monetary penalties, and several closures of illegal occupancy.

The building has maintained an active storefront issue since 2018 regarding an illegal sign, with a final disposition in 2021. Two service requests in 2019 and 2024 related to sewage and appliance issues were investigated and resolved. In terms of maintenance history, there have been no recorded bedbug infestations or re-infestations since 2020, and the building was found to be compliant with recent bedbug reporting requirements.
