This three-story, three-unit old-law tenement building in Sunset Park, owned by Dorothy Cao and constructed in 1910, has experienced several maintenance issues over the past few years, though recent records suggest improvements in building conditions. The most significant cluster of problems occurred in late 2021, when Apartment 3 experienced multiple violations including roach and mouse infestations, defective smoke and carbon monoxide detectors, and inadequate hot water supply; all of these were corrected by October 2021.

The building also had issues with heat and hot water systems in September 2021, though no violations were issued following HPD inspections. Earlier complaints from October 2019 regarding a sewage leak were addressed, and in September 2021, there were concerns about indoor air quality due to chemical vapors. More recent inspections show a notable improvement in building conditions, with the most recent violations from 2023 being related to the failure to file annual bedbug reports, which is a relatively administrative issue.

Importantly, the bedbug reporting history from 2021 through 2025 shows no current or recent infestations, with the last reported cases (3 units) being eradicated by October 2020. Earlier rodent issues were documented in 2011, but recent bedbug and rodent inspections have consistently reported zero infestations. The building's current bedbug and pest control practices appear to be effective, with no reported infestations in the past three years.
