404 20th Ave, San Francisco, CA 94121

The 10-unit, 3-story multi-family residential building at 404 20th Avenue in the Central Richmond neighborhood, owned by the Mak Family Living Trust, was constructed in 1915 and has undergone significant updates in recent years to maintain safety and compliance standards. Most notably, in 2023, the building received a fire alarm system upgrade to comply with San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas and a new fire panel. The property has maintained its soft-story compliance with Tier 4 status showing completed work.

Other recent improvements include the installation of a new pizza oven and range with proper ventilation in 2018, and multiple plumbing upgrades including replacement of the main water supply line and water heater duct improvements. The building has experienced some challenges, particularly in 2002 when it received multiple fire safety violations related to fire escapes, extinguishers, combustible storage, and sprinkler requirements, though these were all abated by May 2003. In recent years, there have been various complaints and service requests regarding sidewalk conditions and debris in front of the building, with multiple reports in early 2025.

The commercial portion of the property has faced routine inspection issues, including several vacant storefront complaints between 2018-2019, and a 2022 complaint regarding an unpermitted awning installation. The building's fire safety record shows occasional alarm activations, one carbon monoxide incident, and two instances of smoke detector activation, though no significant fire incidents or civilian injuries have been reported. The property has also undergone various routine maintenance and safety improvements over the years, including guardrail repairs, seismic retrofitting, and electrical system updates.
