The 9-unit multi-family residential building at 483-497 22nd Avenue in the Central Richmond neighborhood, owned by Xu Min, has undergone several significant maintenance and improvement projects since its construction in 1922. Most notably, the building completed mandatory soft-story seismic retrofitting in 2016 (as a Tier 3 building) and has performed substantial exterior maintenance, including siding replacement in 2020 and 2021 costing a combined $25,000. The property has experienced recurring maintenance issues, including a current active mold complaint from November 2024 regarding water damage to the north wall of the dining room, and a June 2024 complaint about lack of hot water. Historical issues from 2017-2018 included problems with windows, plumbing, and electrical systems, while 2016 violations encompassed multiple safety concerns including security and electrical issues. The building has undergone several infrastructure upgrades, including water heater replacement (2013), sewer system repairs (2007), and individual unit improvements such as closet addition (2018) and kitchen countertop replacement (2010). Recent complaints (2023-2024) have primarily involved external issues such as garbage, debris, and parking concerns, though these are not directly related to building maintenance. The property has maintained compliance with safety requirements, completing necessary fire safety improvements and addressing prior violations, with no recent fire-related incidents or internal complaints.

How 483-497 22Nd Ave's risk score is calculated

What the score means for you
Grade A–B — Low risk
DBI rarely finds violations here. Strong maintenance history and a clean complaint record.
