Augrented Insights Report

The two-unit residential building at 1919 Oakdale Ave, owned by Zhen Chaochang & Tao Zhenla, is a 2-story flats and duplex structure built in 1900 in the Silver Terrace neighborhood. The property has undergone several significant improvements over the years, including a 200-amp electrical service upgrade in 2006 and a reroofing project completed in 2015.

A notable series of violations and complaints surfaced in late 2020, when residents reported critical issues including a lack of gas service, heating, hot water, and functioning appliances, along with stairway problems, though these violations were officially abated by January 2021. The building's history includes prior concerns about unauthorized unit conversions, with complaints in 1997-1999 regarding allegedly illegal attic conversions and unauthorized construction of stairs, though these issues were resolved. Recent records from 2022-2024 show recurring issues with external maintenance, particularly regarding garbage and debris cleanup on the property and surrounding area, as evidenced by multiple 311 calls.

The property has had at least one tenant buyout recorded in April 2020, with compensation of $25,000 paid to one tenant. Other improvements to the property include a horizontal addition completed in 1997 and the installation of a steel staircase, with all associated permits marked as complete. The most recent building activity includes several street cleaning and waste management calls, though these pertain to general neighborhood maintenance rather than building-specific issues.
