671-673 10th Ave, San Francisco, CA 94118

The two-unit residential building at 671-673 10th Avenue in San Francisco's Inner Richmond district is a two-story flats/duplex structure built in 1925, currently owned by the Susan B Waggener Revocable Trust. The property's maintenance record shows consistent attention to window upgrades, with two major window replacement projects: in 2019, six retrofit vinyl windows were installed (non-street facing, cost $6,765), and in 2011, twenty-one street-visible windows were replaced to maintain egress requirements (cost $10,000).

Additional significant improvements include a furnace replacement in 2018 (completed) and a roofing project from 1998, though that permit has since expired. The building's recent history (2018-present) shows a pattern of parking-related issues in the vicinity, with multiple complaints recorded through the 311 system, including instances of sidewalk parking and double parking (most recently in June 2024).

There was also one incident of driveway blocking in July 2018 that was addressed by enforcement officers. A street cleaning issue involving loose garbage was reported in July 2011, though this predates many of the building's recent improvements. While the exterior maintenance work (windows and roof) suggests ongoing upkeep by the current owners, the building's age means regular maintenance of various systems (electrical, plumbing, etc.) should be anticipated, though no such issues have been reported through the 311 system in recent years.
