443 15th Ave, San Francisco, CA 94118

The three-story, seven-unit multi-family residential building at 443 15th Avenue in the Central Richmond neighborhood, owned by Michael Fang, has undergone several significant improvements and renovations since its 1924 construction. Most notably, the building has completed two major fire safety upgrades in recent years: a comprehensive fire alarm system upgrade in August 2024 ($46,500) to comply with SFFD requirements, and the installation of a new residential fire sprinkler system in 2021 ($30,000). The property has also successfully completed seismic retrofit work as a Tier 3 soft-story building, achieving Code Compliance Facility (CFC) status.

In 2019, the building underwent substantial transformation with the addition of three ADU units, converting garage and storage spaces at a cost of $260,000. This work included new kitchens, bathrooms, and laundry facilities in all three units, with associated electrical and plumbing upgrades completed in 2022. The building's infrastructure has been consistently maintained, with records showing a new 400-amp main panel installation in 2024, recent roof work in 2016, and proper attention to garage structural issues in 2003.

Historical violations from 2002 related to fire safety, security, and lead paint concerns were resolved by December 2003, and a mold/mildew complaint from 2008 was also addressed. Recent 311 calls regarding the property primarily relate to street cleaning and maintenance issues, with no recent tenant complaints or violations on record. The building's recent history shows a strong focus on safety and modernization, with significant investments in fire safety systems, seismic retrofitting, and the creation of additional living units through ADU conversions. The property has maintained compliance with current building codes and regulations, with all recent permits marked as complete, including the most recent fire alarm and electrical upgrades.
