Augrented Insights Report

The two-story, four-unit multi-family residential building at 434 4th Avenue in the Inner Richmond, owned by the Theung Quan Bypass Trust, was constructed in 1973 and has demonstrated a pattern of routine safety inspections over the years, with documented inspections in 2001, 2006, and 2016, all of which were completed and notated as "Not Active." The building underwent significant maintenance in 2016 with a $28,000 re-roofing project, while records from 1999 indicate repairs were needed for fire damage in a bedroom ceiling, though this permit has since expired. A cooking-related fire incident was recorded, though it was contained to a container and resulted in no civilian injuries.

More recently, the property has experienced several challenges in late 2024 to early 2025, particularly concerning parking enforcement issues, with multiple citations issued for blocked driveways between November 2024 and January 2025. There were also recurring complaints about garbage and debris on or around the property in December 2024, though these issues were resolved through municipal intervention.

Of particular note is a tenant buyout recorded in September 2024 for $85,000 involving one tenant at 432 4th Avenue, though no additional buyout details were provided. The building's documented history suggests regular maintenance and compliance with safety inspections, though recent months have shown increased neighborhood enforcement actions related to parking and waste management.
