2005-2007 San Jose Ave, San Francisco, CA 94112

This two-unit residential building, located at 2005-2007 San Jose Avenue in Mission Terrace, was constructed in 1910 and is classified as a Flats & Duplex building. The property, currently owned by Tan Huaan & Liang Su Hong, has undergone several significant renovations and faced multiple compliance issues over the years. In 2013, substantial work was completed on the third floor, including the addition of laundry facilities and two new dormers, following a notice of violation for unauthorized construction.

The building received a major electrical upgrade in 2006, with a 400-amp service installation and three meters, supporting additional laundry and shop equipment. Earlier improvements included a backyard and hallway concrete pour in 1998, reroofing work in 1997, and comprehensive remodeling of the lower unit's kitchen and bathroom in 1995. The property has experienced several housing code violations and complaints throughout its history, with the most recent undocumented incident in 2017 regarding unauthorized construction of a large shed or dwelling in the backyard.

Multiple complaints about unpermitted construction work were filed between 2000 and 2017, though most have been marked as not active. Recent activity at the property between December 2024 and January 2025 has primarily consisted of parking violations and municipal maintenance issues, with several reports of blocked driveways and garbage concerns, though these are not directly related to building safety or habitability. While there was one fire-related complaint in 2018, it was deemed to have no merit. The property history shows compliance with most building requirements following violations, but the persistence of some unauthorized construction claims suggests ongoing concerns about proper permitting procedures.
