3275-3279 16th St, San Francisco, CA 94103

The three-unit, three-story multi-family residential building at 3275-3279 16th Street, constructed in 1907, is currently owned by the Children's Day School and has undergone significant transformations over the years. In 2009, the building was converted from residential to educational use, with comprehensive safety improvements including the installation of a new fire sprinkler system ($30,000), a fire alarm control panel with new horn/strobes and smoke detectors ($20,000), and associated plumbing work. The conversion project cost approximately $214,124 and was completed successfully. The building's history reveals several concerning safety issues, most notably a cluster of active housing code violations dating from March 2006 related to fire safety, security, and structural integrity, including problems with stairs, handrails, self-closing devices on doors, and fire-related storage concerns.

These violations were documented through routine inspections and have not been marked as resolved in the provided records. Other historical issues include a plumbing leak complaint from 1997, construction-related complaints in 2004-2009, and various renovation projects including electrical upgrades and bathroom work. Recent 311 calls from 2024 primarily relate to street and sidewalk maintenance issues, though these do not directly indicate problems with the building itself. A 2009 complaint was filed regarding drilling work impacting a neighboring property, though this was quickly resolved.

The building has undergone various improvements over the years, including a 2005 rear addition with covered porches and stairs, extensive electrical work in 2003, and multiple plumbing upgrades. The most recent building-related issues concern exterior maintenance and public space concerns rather than structural or safety problems within the building itself. Fire department responses in recent years have been limited to false alarms with no incidents found upon arrival. The property's zoning and planning records indicate successful conversion to school use and approved plans for rear egress stair replacement, though these changes were previously marked "Removed" in planning records.
