20 Mallorca Way, San Francisco, CA 94123

20 Mallorca Way is a 6-unit, 3-story multi-family residential building located in the Marina neighborhood, owned by Benjamin P & Katherine C Li and constructed in 1929. The property has undergone several maintenance and improvement projects over the years, with the most recent being a back door replacement in late 2024. Previous significant work includes re-roofing in 2013 and bathroom/kitchen renovations in 2007.

A notable cluster of building violations was recorded in November 2009, primarily related to fire safety and mental health concerns, including issues with the fire escape system, central alarm system, sanitation matters, and interior surface repairs – all of which were abated by December 2009. While the building has experienced three fire-related incidents, all have been false alarms or service calls with no civilian injuries reported. The property's recent history shows various municipal service interactions, particularly in 2024, including multiple reports of garbage and debris issues, some environmental health complaints, and one instance of a sidewalk defect attributed to tree roots.

Several parking-related incidents have also been recorded, including double parking and blocking driveway violations. The maintenance history suggests regular upkeep of the building's infrastructure, with the most recent modifications continuing the trend of upgrading building features. The structure's age and location have resulted in typical urban challenges such as sidewalk maintenance needs and street cleaning concerns, which appear to be generally addressed through appropriate channels.
