410 Pierce St, San Francisco, CA 94117

The three-story, 9-unit multi-family residential building at 410 Pierce Street in Hayes Valley, owned by Plaza Group LLC, has undergone several significant improvements since its construction in 1900. Most notably, the building completed mandatory soft-story retrofit work in 2018, following San Francisco's seismic safety requirements, with a total cost of approximately $76,000, demonstrating compliance with Tier 3 soft-story requirements.

Recent improvements include a $25,000 renovation of Unit 6 in 2019 (including kitchen and bathroom updates), following a similar $18,000 remodel of Unit 3 in 2015, both of which involved plumbing and electrical upgrades. The building's infrastructure has seen essential maintenance, including the replacement of an underground clay sewer line section in 2007.

The property has undergone regular routine safety inspections by Housing Inspection Services between 1997 and 2017, with no active violations recorded. However, there was a concerning series of fire safety issues documented in 2006, including violations related to fire alarms, extinguishers, and combustible storage under stairs, all of which were subsequently closed. The building's fire safety systems appear to have been properly maintained since then, with the most recent fire alarm system complaint in 2015 being marked as "Condition Corrected." The property has seen multiple street space permits issued between 2014 and 2018, suggesting ongoing attention to the building's exterior and surrounding areas.
