1840 Larkin St, San Francisco, CA 94109

1840 Larkin Street is a three-story, six-unit multi-family residential building located in San Francisco's Nob Hill neighborhood, built in 1910. The property has undergone several significant safety and infrastructure upgrades in recent years, including a fire alarm system upgrade in 2023 ($18,969) to meet current fire code requirements with 75dB sounders in sleeping areas, and a completed soft-story retrofit in 2015 ($75,000) to improve seismic safety. Other recent improvements include a re-roofing project in 2020 ($21,500) and a major remodel of Unit 5 in 2018 ($34,872) that included kitchen and bathroom renovations with associated electrical upgrades.

The building's history shows proactive maintenance and compliance with safety standards, including window replacements in 2013 and various unit-specific renovations. However, there was a cluster of building violations recorded in 2000-2001 related to various maintenance and safety issues, including mold, wall damage, and fire safety concerns, all of which were abated by November 2000. The property has undergone regular routine inspections since then, with no active violations on record. Recent 311 calls primarily relate to street cleaning and parking enforcement issues outside the building, while records of fire department response show no significant fire incidents, with most responses being related to alarm malfunctions or routine service calls.

The building's electrical system has received significant attention over the years, with multiple upgrades including a comprehensive 400-amp service installation for all units in 2003 and various unit-specific electrical improvements. The most recent work in 2023 included fire alarm system upgrades, indicating ongoing attention to safety systems. The soft-story retrofit completed the building's mandatory seismic improvement requirements, and the property has maintained active compliance with housing codes through regular inspections and timely response to any identified issues. The substantial investment in safety upgrades and routine maintenance suggests a commitment to maintaining the building's structural integrity and resident safety.
