Augrented Insights Report

The two-story, four-unit multi-family residential building at 358 21st Avenue in the Central Richmond neighborhood was constructed in 1923 and is currently owned by George Chew and Louise H Mar. The building's maintenance and safety history reveals several areas of concern, most notably from a routine inspection in October 2014, which generated multiple active violations related to fire safety and lead paint hazards, including the need for proper fire safety equipment, addressing egress obstructions, and managing lead paint concerns.

In September 2019, a complaint was filed citing significant disrepair issues throughout the building, including water leaks, mold, non-functioning intercom systems, and unauthorized unit modifications, though this complaint is now listed as not active. The building has undergone several permitted modifications over the years, including interior partition work in 1985 and 1994, and a street space permit in 2010. More recent history shows some maintenance activity, with various 311 calls in 2022-2024 primarily relating to street cleaning and scooter-related services, though these are not directly related to building conditions.

Two fire-related incidents were recorded, but both were false alarms with no injuries reported. While the building has a history of periodical inspections and compliance issues, many of the older violations from 2000 are no longer active. The property recently experienced construction activity in 2020 that generated noise complaints during shelter-in-place orders.
