Augrented Insights Report for 8670 20th Avenue

The two-story, three-unit building at 8670 20th Avenue in Bath Beach, owned by Kwok Chiu, has been subject to several regulatory requirements and violations since its construction in 1990. Most notably, there appears to be an ongoing issue with timely bedbug report filings, with violations recorded in 2023, 2024, and 2021, specifically related to the failure to submit annual bedbug reports as required under the Housing Maintenance Code.

However, recent bedbug reporting from late 2024 shows no infested units, suggesting successful management of this particular issue. The building has experienced recurring complaints about illegal conversions from 2020 to 2023, though in each case inspectors were unable to gain access during their two final attempts to verify the claims.

Additionally, there are two active Environmental Control Board violations from 2018 related to unauthorized work and parking regulation violations: one concerning an unpermitted curb cut near the front entrance and another regarding unauthorized parking of two vehicles in a residential district, each carrying a $500 penalty. While these violations are relatively old, their ongoing status should be noted. The property has maintained consistent compliance with the bedbug reporting requirements in recent years, with the most recent filings showing no evidence of infestation across any units.
