764 Arguello Blvd, San Francisco, CA 94118

The two-unit residential building at 764 Arguello Boulevard in Lone Mountain, owned by Matsuoka Akio & Amarzan Tr, is a two-story flats and duplex structure built in 1923. The property has experienced recurring water-related issues over its history, with multiple complaints and violations between 2004 and 2013 indicating problems with leaks, water damage, and interior surface degradation, including mold and mildew concerns.

Significant events include a water leak complaint from a bedroom ceiling in November 2013, unauthorized siding removal reported in December 2009, and the most serious incident in January 2004 when an exterior wall was reportedly ripped away, exposing a kitchen area and creating safety concerns with scaffolding that remained for two years. Building maintenance has included a complete reroofing project in 2013 costing $10,900, suggesting efforts to address these persistent water issues.

The building's recent history shows continued attention to property management matters, with several 311 calls in 2024 related to garbage and debris, though these appear to be external to the building itself and were primarily resolved through city services. Other historical complaints include concerns about trees damaging property through root infiltration (2017), environmental health requests (2020), and various routine municipal service matters. While many of the earlier violations and complaints were resolved within weeks of being reported, the property has maintained a record of periodic maintenance issues, particularly related to water damage and unauthorized modifications, though there have been no significant building code violations reported in recent years.
