3435 18th St, San Francisco, CA 94110

The 12-unit, three-story multi-family residential building at 3435 18th Street in the Inner Mission, owned by Litke Marghenta, was constructed in 1923 and has undergone several significant safety improvements over recent years. Most notably, the building completed its mandatory soft-story retrofit in 2017 (with subsequent revisions) at a cost of $82,000, demonstrating compliance with San Francisco's seismic safety requirements.

The property has also recently updated its fire safety systems, with a fire alarm system upgrade completed in 2024 costing nearly $35,000, including the installation of low-frequency sounders in sleeping areas and a new fire alarm panel. The building has experienced periodic safety and maintenance challenges, including a cluster of violations in September 2023 related to fire escape maintenance, gas shutoff requirements, and various compliance affidavits, though these were all abated by June 2024. There was also a significant complaint in June 2017 regarding construction debris during the seismic retrofit work, and a serious incident in 2008 involving scalding water affecting a tenant.

The property has maintained an active history of regular updates, including boiler system improvements in 2023 and 2017, electrical service upgrades, and roofing work in 2004 and 1997. Recent inspections and work suggest ongoing attention to building safety, though the frequency of various complaints and violations over the years indicates typical urban building maintenance challenges. The building is categorized as a Tier 3 soft-story property, with its retrofit work completed and certified.
