420 20th Ave, San Francisco, CA 94121

The two-story, 10-unit apartment building at 420 20th Ave in the Central Richmond neighborhood, owned by John P & Sarah N Healy, was constructed in 1960 and has undergone several maintenance and improvement projects over the years. The most recent building permit was issued in 2013 for window replacements in Unit #8, featuring energy-efficient double-pane vinyl windows. The property has a documented history of compliance issues, particularly in January 2003, when multiple violations were recorded related to fire safety, including problems with fire escape ladders, combustible storage, and fire extinguisher maintenance - all of which were resolved by February 2003.

A more recent complaint from May 2023 reported ceiling framing/subfloor problems in Unit 1, though this issue is listed as "Not Active" with no recorded resolution date. Routine housing inspections have been conducted in 2003, 2010, and 2014, with the 2014 inspection identifying issues with the fire alarm system that were corrected by March 2015. The building's fire safety history includes three documented violations: in 2005 for combustible materials (resolved), in 2014 for alarm systems (resolved), and in 2017 for fire extinguishers (resolved).

The property has experienced recurring issues with parking enforcement, as evidenced by numerous 311 calls between 2019 and 2024, primarily regarding driveway blockages, though these are separate from the building's structural and safety concerns. The building's maintenance record shows attention to basic upkeep, including reroofing work completed in 1988, though this is quite dated relative to the building's current age. The ongoing nature of the 2023 ceiling/subfloor complaint and the relatively infrequent major improvements suggest that building systems and infrastructure may be approaching typical end-of-life conditions for a structure of this age, though no current violations or active complaints are on record regarding these systems.
