4623-4625 Anza St, San Francisco, CA 94121

The property at 4623-4625 Anza Street is a four-story multi-family residential building constructed in 1946, containing two units. The building has undergone significant improvements over the past decade, most notably the installation of a comprehensive fire sprinkler system in 2012-2013, which included 80 heads and underground components, costing approximately $40,000.

In 2012, substantial modifications were made including basement excavation work with shoring costing $125,000, followed by extensive plumbing renovations in 2012-2013 that involved installing new bathrooms, kitchens, gas mains, condensing boilers, storage tanks, and radiant pex pipe systems. The building's renovation period saw multiple complaints in 2012-2013 regarding potential unauthorized work and height concerns, though these complaints were marked as not active. Electrical upgrades were completed in 2013 with a complete rewire and Ufer ground installation.

While the property has experienced recurring issues with driveway blocking, as evidenced by multiple parking enforcement calls between 2018 and 2023, these incidents are not directly related to the building's structural or safety features. Recent building permits issued in 2013-2014 primarily concerned street space usage. A proposal for a rear yard variance to construct a three-story addition was submitted by developer David Armour, but records indicate this was eventually withdrawn or closed.
