742-746 Thornton Ave, San Francisco, CA 94124

742-746 Thornton Avenue is a two-story multi-family residential building located in the Silver Terrace neighborhood, owned by Huang Run Qiang and Zhang Min. The 3-unit apartment building, constructed in 1911, has undergone several maintenance and improvement projects over the years. Most recently, in January 2020, the property received approval for window replacements, specifically installing aluminum clad double hung windows on both the ground and second floors, with an estimated cost of $3,500.

This followed earlier work in 2007 for deck repairs, though that permit ultimately expired. A significant cluster of violations was documented in July 2007, including safety concerns such as the need for fire extinguishers, fire escape maintenance, and building permit requirements, along with issues related to stairs, plumbing, electrical systems, and sanitation. These violations were all addressed and abated by December 2007. The property has a history of routine housing inspections, including one in 1999 that was resolved within a month.

More recently, the building's surroundings have experienced numerous parking-related incidents, with multiple reports of sidewalk parking and other violations recorded in late 2024, though officers were often unable to validate these complaints. Between September and December 2024, there were also several structural maintenance calls regarding recreational equipment, suggesting nearby park facilities may require attention. While these recent incidents are more related to the neighborhood's parking and park infrastructure rather than the building's condition itself, they represent the most recent activity associated with the address. The building's documented history shows a pattern of maintenance and compliance with housing requirements, particularly following the 2007 violations which appear to have been comprehensively addressed.
