421 Arguello Blvd, San Francisco, CA 94118

421 Arguello Boulevard is a 4-story, 8-unit multi-family residential building constructed in 2012 by Golden Properties LLC in San Francisco's Inner Richmond neighborhood. The building underwent significant construction work between 2007-2012, including the installation of comprehensive fire safety systems (sprinklers, alarms), heating and ventilation systems, full electrical service upgrades, and complete plumbing infrastructure for all units. During construction in 2010, the property faced multiple violations related to vacant or abandoned building ordinances, though these were resolved by June 2010.

In 2012, the building received its final inspections for several permits and underwent a house trap replacement. Recent concerns have focused on exterior modifications, with complaints filed in February 2023 regarding newly installed lights on the building's roof affecting residents' quality of life. The building has maintained its infrastructure with recent upgrades including EV charging facilities installed in 2016.

Fire safety compliance appears generally stable, with violations recorded in 2018 related to exit pathways, electrical clearance, and alarm system maintenance, all of which were abated. The property experienced one incident of elevator failure in 2012 and multiple fire-related service calls, mostly for false alarms or minor issues. Recent activity around the building primarily involves external issues such as graffiti and parking violations, with the most recent reports from late 2024 related to parking enforcement and defaced city signs. The building's original construction involved addressing specific zoning requirements, including a variance for rear yard setback to convert a former garage structure into residential use, which was approved as part of the overall development project.
