133 11th Ave, San Francisco, CA 94118

The property at 133 11th Avenue in the Lake-Presidio neighborhood is a two-unit, two-story multi-family residential building built in 1902, currently owned by Chris W. and Valerie O. Fong.

The building has undergone several significant maintenance and repair works over the past two decades, most notably a sewer line replacement in 2021 and a front stair landing repair in 2003 to address rotted wood. The building faced multiple housing violations in 2002-2003 related to water damage, interior surface issues, and window frame repairs, all of which were officially abated by April 2003. Earlier maintenance issues included a roof replacement in 1999, though that permit ultimately expired.

The property has a documented history of water-related problems, with complaints in 2001 regarding plumbing issues (including reports of a broken main pipe), and a 2004 complaint about water damage and mold causing tenant health concerns. A fire-related complaint was filed in 2005 but was resolved within a month. More recent concerns have primarily revolved around parking issues near the property, with numerous 311 calls in 2023-2024 regarding blocked driveways and illegal parking, though these are external to the building's conditions. The building's maintenance record shows periodic attention to both routine and urgent repairs, with most historical violations being addressed through proper channels and permits.
