250 Somerset St, San Francisco, CA 94134

The building at 250 Somerset Street, located in the Portola neighborhood, is a one-story multi-family residential structure built in 1934, containing two legally recognized units (R-3 classification). The property is currently facing significant legal and safety concerns, with active building violations filed in April 2024 citing numerous infractions related to unauthorized construction work.

These violations include unpermitted construction of a 20x20-foot rear structure containing a habitable room, bathroom, and closet, along with issues such as unapproved wiring and plumbing, lack of proper fire construction materials, inadequate light and ventilation, insufficient heating systems, missing smoke detectors, and absence of carbon monoxide alarms - all of which pose serious safety risks to occupants. Recent activity at the property has generated multiple complaints and service requests throughout early 2025, predominantly related to waste management issues including garbage, debris, and abandoned holiday items on and around the property.

There are also current enforcement actions regarding illegal parking, though this is a separate issue from the building's structural and safety concerns. While the building had a reroofing project permitted in 1995, this work is now considered expired. The property's most pressing concerns remain the active building violations from 2024, which have received initial Notices of Violation (NOV) in August 2024 but no subsequent resolution as of the latest available data.
