641-647 Balboa St, San Francisco, CA 94118

The two-story, four-unit multi-family residential building at 641-647 Balboa Street in the Inner Richmond, owned by Mary Wong Sit Testamentary, was constructed in 1923 and has undergone several significant improvements over the past two decades. Major renovations between 2005-2006 included comprehensive bathroom and kitchen remodels, electrical upgrades to 200-amp service with five meters, and a new roof installation costing $11,000. In 2011, the building received a furnace replacement and associated flue work.

A routine inspection in December 2015 revealed multiple violations requiring attention, including the need for structural maintenance documentation, proper fire extinguishers, and water heater bracing, though these were all abated by January 2016. The building experienced one heating-related complaint in 1996, which was resolved within a month. Recent activity at the property has primarily involved exterior maintenance and parking enforcement issues.

From 2022 through 2024, there have been multiple complaints about parking violations (primarily sidewalk parking) and occasional garbage and debris issues on the property and surrounding area, with the most recent incidents occurring in October 2024. While the building's major systems have been upgraded and maintained over the years, including electrical, plumbing, and roofing systems, there was a period of fire safety concerns in 2005 including violations related to combustible storage and proximity to heaters, though these were subsequently addressed. The property has generally been well-maintained since the 2015 violations were resolved, with no significant building or safety violations recorded in recent years.
