31-33 Castillo St, San Francisco, CA 94134

The three-story multi-family residential building at 31-33 Castillo Street in Visitacion Valley is a duplex property, constructed in 1948 and currently owned by Diana Fei Wang. The building has undergone significant improvements in recent years, with a comprehensive renovation completed in 2018 that included bathroom and kitchen remodels in both units, installation of fans, and a substantial electrical upgrade featuring a 200-amp service installation, three meters, and various new electrical fixtures including smoke detectors.

Additional improvements included a new roof installation in 2018, with the previous roofing permit from 1992 having expired. The property has experienced recurring issues with parking violations in 2021, particularly concerning driveway blockages, with multiple citations issued, though some vehicles were not located during enforcement attempts.

The street and sidewalk areas around the property have required multiple cleaning interventions from the Department of Public Works, particularly in 2022, with reports of loose garbage. Recent activity includes a mechanical street sweeping issue in February 2024, which has been resolved. The building's permit history shows consistent maintenance and upgrading of facilities, with no recorded serious safety concerns or major incidents affecting resident living conditions.
