850-858 Presidio Ave, San Francisco, CA 94115

The 850-858 Presidio Avenue property is a two-story, four-unit multi-family residential building located in Lower Pacific Heights, constructed in 1906 and currently owned by Do Dung M. The building has experienced several significant maintenance and safety issues over the past decade, with particular attention required to recent complaints. Most notably, in late 2024, there were reports of a non-working light fixture, potential pest issues, exposed electrical wires, external wall cracks, bathroom ventilation problems, and mold in one unit.

Previous building violations from 2015-2016 had documented issues with paint condition (including lead paint concerns), window frames, kitchen door frames, and weatherproofing, though these were reportedly abated by March 2016. The property has undergone various infrastructure upgrades including a new fire alarm panel installation in 2019, HVAC system improvements (furnace and water heater replacements), and electrical system upgrades such as dedicated circuits and fire safety improvements. The building's maintenance history shows a pattern of reactive rather than preventative maintenance, with multiple permits issued for repairs and compliance issues over the years.

Significant repairs have included stair repairs to address safety concerns, completion of roofing work (2012), and various electrical system improvements. Historical records indicate a previous complaint in 2008 regarding ventilation and egress issues related to neighboring construction. The property has also been subject to several 311 calls in recent months (October-December 2024) primarily related to street cleaning and parking enforcement matters outside the building, suggesting ongoing maintenance challenges in the immediate vicinity.
