448 Laurel St, San Francisco, CA 94118

The 6-unit, 3-story apartment building at 448 Laurel Street in Presidio Heights, owned by the Chang Family Trust, was constructed in 1912 and has undergone several significant maintenance and safety upgrades in recent years. Most notably, in April 2024, the building completed a major fire alarm system upgrade costing over $27,000 to comply with San Francisco Fire Code requirements, including new low-frequency sounders in sleeping areas and updated devices compatible with the new fire alarm control panel.

Prior improvements include window replacements in 2015 (replacing 18 windows with energy-efficient Marvin Integrity wood clad windows) and a complete reroofing project initiated in 2013. The building has a documented history of routine safety inspections by Housing Inspection Services from 2001 to 2016, all of which were marked as not active, suggesting no significant violations were found. The property has experienced several fire alarm system-related complaints between 2006 and 2024, most of which were resolved with conditions corrected, indicating normal maintenance and system upkeep.

There have also been three 311 calls in January 2025 related to water leaks and garbage issues, though these were addressed promptly. While there have been multiple fire-related incidents recorded (mostly false alarms and smoke detector activations with no actual fires or injuries), these appear to be typical for buildings of this age and type, and recent fire safety upgrades suggest an ongoing commitment to resident safety. The building's permit history shows regular maintenance and upgrading of systems, with no significant safety violations or building complaints on record.
