Augrented Insights Report

The building at 302-316 20th Avenue in the Central Richmond neighborhood is an 8-unit, 2-story multi-family residential property built in 1921 and currently owned by Sheila H Tsang. The property has undergone numerous renovations and repairs over the years, with significant updates occurring in 2019 including bathroom remodels in multiple units (302, 306, 316), kitchen remodels, and various electrical improvements. More recent work includes a completed circuit breaker panel relocation in November 2022 and sewer line repairs in front of the building in June 2020.

The building successfully completed its mandatory Soft Story retrofit program and has received its Certificate of Final Completion. The property has a notable history of maintenance and compliance issues, particularly regarding permit violations and safety concerns. Multiple complaints from 2002 and 2008 documented various violations including unpermitted work, electrical issues, and absence of smoke detectors.

Recent inspection records show recurring sewer-related issues, with the most recent incidents in 2024 involving flooding and sewage backup problems, although these were resolved according to PUC records. The building has experienced several parking enforcement issues in 2024, with multiple complaints about blocked driveways resulting in citations. While many historical violations were abated, including those related to fire safety and security requirements in 2002, the building's maintenance record shows ongoing challenges with infrastructure systems, particularly plumbing and electrical systems, as evidenced by multiple permit requests and repairs between 2008 and 2019.
