Augrented Insights Report for 447 9th Street

The three-story, three-unit Old Law Tenement building at 447 9th Street in Park Slope, owned by William Walsh, has maintained a consistent record regarding its bedbug reporting requirements and building maintenance over recent years. Built in 1881, this property has demonstrated effective pest management protocols from 2019 through the present, with no reported incidents of bedbug infestations in any of the past four years' filings (2019-2025).

The building's Annual Bedbug Reports, which are mandatory under the Housing Maintenance Code, have been consistently filed showing zero infested, eradicated, or re-infested units. In terms of building maintenance, the property has experienced recurrent Housing Maintenance Code violations regarding the timely filing of annual bedbug reports between 2022 and 2024.

However, these violations appear to have been administrative in nature, as evidenced by the subsequent correct filings showing no evidence of actual infestations. The building underwent some renovation or maintenance work in 2019, as indicated by multiple permits issued during that summer for plumbing (PL) and exterior work (EW), though the specific nature of these improvements is not detailed in the available records. All permits were properly issued and there are no open violations related to this work.
