231-235 Collingwood St, San Francisco, CA 94114

This 4-unit, 2-story multi-family residential building located at 231-235 Collingwood Street in the Eureka Valley/Dolores Heights neighborhood was built in 1907 and is currently owned by David Del Rosario. The property has undergone several significant renovations and faced multiple compliance issues over its history, with the most recent concerns centering around heating and fire safety systems.

In 2022, the building experienced heating system complaints that resulted in violation notices, though these were marked as not active by June 30, 2022. A notable pattern of building code and safety compliance issues emerged in 2022/2023, including a sprinkler system violation issued in June 2023 that was later abated by September 2023, along with similar concerns regarding heating systems and fire safety documentation requirements.

The building underwent a kitchen renovation in 2015, including electrical and plumbing work totaling approximately $26,000, but has experienced recurring infrastructure challenges, including historical issues with stairs (repairs noted in 2002) and multiple citations regarding unauthorized basement modifications, including plumbing and electrical work. Recent activity shows recurring issues with parking enforcement in the area, with multiple citations issued for driveway blocking between 2021 and 2024, though these are not directly related to building conditions. The property has maintained its legal designation as an R-1 occupancy with four dwellings over two floors plus basement/storage space, despite past concerns about unauthorized modifications and occupancy use.
