3764 20th St, San Francisco, CA 94110

The three-unit, three-story multi-family residential building at 3764 20th Street in Mission Dolores, owned by the Barrios Family Trust, was constructed in 1986 after previously being a light-hazard structure with a completed sprinkler system installed in 1983. The property has experienced several notable incidents, most significantly a fire in 2010 that required substantial repairs to the garage area, floor joists, cripple walls, subfloors, and storage area, with work valued at $12,000.

Prior to this, in 2007, there were issues with water drainage from the roof causing exterior wall damage and mold concerns at the neighboring property, and a construction-related complaint regarding unpermitted roof work that was resolved in early 2010. In recent years, the property has generated numerous parking enforcement calls, particularly between February 2024 and October 2024, with ten separate incidents involving blocked driveways and citations issued, reflecting ongoing parking challenges in the area.

While not directly impacting resident safety, these incidents may affect convenience. The building's maintenance history shows attention to fire safety systems, as evidenced by the 1983 sprinkler installation and resolution of a fire escape violation in 2007, suggesting compliance with basic safety requirements. The most recent significant building permit activity was in 2010, though records for earlier permits from 1982-1985 are present but without specified details.
