839 Jones St, San Francisco, CA 94109

The four-story, 17-unit apartment building at 839 Jones Street, owned by Szeto Whalun & Ava and constructed in 1916, has experienced several significant maintenance and safety issues over its history, with particular concerns in recent years. Most notably, the building is currently undergoing a fire alarm system upgrade, as evidenced by a filed permit in January 2025, and has faced recurring issues with mold, ventilation, and general maintenance. A series of complaints in late 2021 documented problems including mold in bathrooms, drafty windows, slow hot water heating, and interior surface issues, while more recent city service calls have been concentrated on street cleaning and sanitation matters around the building.

The property has received several fire safety citations, including blocked exits (2017), sprinkler system issues (2015), and alarm system concerns (2011), though these were generally promptly addressed. Historical records show the building underwent significant seismic upgrades in 1999 ($85,000 improvement), completed reroofing in 1998, and parapet reinforcement in 1989. Various maintenance violations were recorded between 2001 and 2004, including problems with elevator functionality, skylight leaks affecting the fifth floor hallway, and fire escape maintenance needs.

The building's management has faced scrutiny regarding potential illegal units, with inspections in 2010/2011 investigating ground floor spaces reportedly lacking proper fire escape access. More recently, between 2024-2025, there have been multiple reports of sidewalk sanitation issues near the property, though these are more related to street-level conditions than the building itself. Regular zoning verification letters have been issued for the property, indicating compliance with local regulations though their specific content is not detailed in the provided record.
