807-809 Russia Ave, San Francisco, CA 94112

The two-unit multi-family residential building at 807-809 Russia Avenue in the Excelsior neighborhood, owned by Zhen Zhuan Juan, has undergone several significant maintenance and improvement projects since its construction in 1927. The most recent major improvement was completed in 2017, involving the installation of aluminum wood-clad double-hung windows in the front facade to meet emergency escape and fire safety requirements.

The property experienced compliance issues in early 2014 when unauthorized interior remodeling work was discovered in unit 809, including kitchen and bathroom modifications, which led to a notice of violation and subsequent permitted work totaling approximately $29,277 to correct the unauthorized renovations, along with associated electrical and plumbing upgrades. The building has also required ongoing maintenance, including a complete reroofing project in 2017 (cost: $7,300) and an electrical service upgrade to 125A in 2012.

Of particular concern is a documented history of sewer system issues, with multiple 311 calls reporting sewage back-ups from the 4-inch vent in mid-2022. The property has experienced recurring issues with vehicles parking on the sidewalk adjacent to the property, with at least six documented incidents between 2019 and 2023, and one notable sidewalk defect incident in June 2020 involving a collapsed section that required attention from SFPUC Water utilities. While the building has undergone various improvements and maintenance activities, the history of unauthorized renovations and recent sewer issues suggest areas requiring ongoing attention.
