31-35 Frederick St, San Francisco, CA 94117

The property at 31-35 Frederick Street is a two-story, three-unit multi-family residential building located in the Buena Vista Park neighborhood. Built in 1928 and currently owned by the William A Werner Revocable Trust, the building has undergone several significant maintenance and upgrade projects over the years. Most recently, in 2021, four non-street-facing windows were replaced with wood composite units at a cost of $13,269.

A major systems upgrade was completed in 2016 with the installation of a new heating system and backflow prevention assembly for all three units. The building has experienced two routine housing inspections by Housing Inspection Services, one in 2003 and another in 2017, which revealed several fire safety issues that were subsequently addressed. The 2017 inspection resulted in violations related to fire proofing, which was abated by August 15, 2017.

The 2003 routine inspection led to multiple fire safety violations including problems with egress obstruction, fire extinguisher charging, combustible storage, and garbage receptacle placement, all of which were resolved by February 2004. More recent municipal records show multiple parking-related issues in the surrounding area, with several reports of vehicles blocking driveways or parking on sidewalks between January and October 2024. Additionally, there are two open cases from March 2024 regarding structural maintenance issues in the adjacent park area, specifically related to graffiti. While these parking and park maintenance issues are not directly related to the building's condition, they provide context about the immediate neighborhood's current concerns.
