3745-3751 Cabrillo St, San Francisco, CA 94121

The 4-unit multi-family residential building at 3745-3751 Cabrillo St in the Outer Richmond neighborhood, owned by Richard & Theresa Y Won, was constructed in 1948 and stands two stories tall. The property has undergone several significant improvements over the past decades, with the most recent major renovation occurring in 2021, which included kitchen and bathroom remodels in all units, conversion from gas to electric appliances, and associated electrical and plumbing work totaling approximately $30,000. Prior to this work, there were serious concerns raised by residents in July 2021 about unauthorized remodeling, including alleged plumbing and electrical modifications, asbestos/lead dust, structural concerns, and safety issues related to smoke alarms and fire extinguishers, though these permits were subsequently properly documented and completed.

The building's history shows a pattern of maintenance and safety concerns, particularly in the 2000s, when multiple violations were recorded in September 2010 related to fire safety (including fire extinguisher requirements), building exterior maintenance, and seismic bracing of water heater storage tanks. These violations were all marked as abated by October 21, 2010. A notable plumbing issue occurred in 1998 with a sewage overflow problem. The property has experienced recurring infrastructure issues in recent months, most significantly evidenced by multiple sewer-related complaints, including an October 2024 sewage backup/discharge incident and recent plumbing maintenance issues.

There have also been numerous parking-related complaints in recent months (October-November 2024), though these are not directly related to building conditions or maintenance. The most recent active issue as of October 2023 appears to be concerns regarding an overgrown tree blocking street lights, reported in September 2024. While the building has received various upgrades and maintained compliance with most housing codes over time, the presence of recent plumbing issues and ongoing parking management challenges in the vicinity may indicate some infrastructure strain. The property's documented improvements, particularly the 2021 renovations, suggest efforts to maintain and upgrade building systems, though the initial unauthorized work and related complaints in 2021 indicate there was a period of construction activity that raised significant resident concerns regarding safety and code compliance.
