4451-4457 California St, San Francisco, CA 94118

The property at 4451-4457 California Street in San Francisco's Inner Richmond district is a two-story multi-family residential building constructed in 1903, containing 4 units under the ownership of Andrew W & Mabel W Gee Revo. The building has undergone several significant renovations and repairs over the years, most notably following a fire in 2004 that damaged a portion of the roof, prompting $12,000 in emergency repairs and subsequent electrical work that included the installation of new panels and circuits throughout all units.

In 2007, substantial interior improvements were completed at a cost of $10,000, including wall modifications to improve unit layouts and add new closets, along with electrical upgrades and plumbing work including sewer pipe replacements in 2008. The building has been subject to regular housing inspections, with documented violations in 2001 and 2017.

The 2001 violations primarily concerned fire safety issues, including fire extinguisher maintenance, fire proofing, and self-closing doors, all of which were resolved by April 2001. The 2017 inspection identified several safety concerns including the need for carbon monoxide detectors, egress obstruction removal, and other maintenance items, which were addressed by July 2017. More recent activity at the property has involved routine maintenance and compliance matters, with multiple 311 calls in late 2024 primarily relating to street cleaning and parking issues outside the building, and two recent graffiti reports in November 2024.
