4121-4123 Anza St, San Francisco, CA 94121

The property at 4121-4123 Anza Street is a two-unit, two-story multi-family residential building located in San Francisco's Outer Richmond neighborhood. Built in 1925 and currently owned by the Gregory K Low Childs Trust, this flats and duplex structure has undergone several significant renovations over its lifetime. The most substantial improvement occurred in 2007-2009, when approximately $70,000 was invested in adding a bedroom, family room/laundry room, half-bathroom, and storage space to the lower unit, along with a complete remodel of the second-floor bathroom and third-floor kitchen.

This renovation project also included the installation of two new bathrooms, one kitchen, two water heaters, and two furnaces, along with electrical upgrades comprising 20 lights, 10 switches, 20 receptacles, and 3 main services. The building received a new roof in 2009, with earlier roofing work completed in 1992. The property's maintenance record shows attention to basic infrastructure, including historical documentation of side stairs repairs in 1990.

While there have been no reported internal issues or safety concerns, the surrounding area has experienced some recurring pavement defects, with four such issues reported and resolved in 2022, and two parking-related incidents in 2024 (one for blocking a driveway and another for sidewalk parking). The only recorded fire-related incident occurred with a detector activation that was determined to be unintentional, with no injuries reported. The building's permit history demonstrates proactive maintenance and upgrading of essential systems, particularly during the 2007-2009 renovation period, with all major work properly permitted through appropriate channels.
