473 10th Ave, San Francisco, CA 94118

The 9-unit, 3-story multi-family residential building at 473 10th Avenue in the Inner Richmond, owned by Chan Lvg Tr and built in 1961, has undergone several significant improvements and faced some maintenance challenges over its history. Most notably, the building completed a mandatory soft-story retrofit in 2015 (Tier 3) at a cost of $50,000, which included structural reinforcement of the ground floor with special moment frames, foundation work, and anchor bolting. Recent major maintenance includes a reroofing project completed in 2022 valued at $27,500, and the building previously underwent window upgrades in 1987 with the installation of 56 aluminum windows, along with dry rot repairs and re-stucco work in 1992.

The building experienced a cluster of interior maintenance issues in 2019, when multiple violations were filed regarding damaged walls, ceilings, floors, and lead paint hazards, particularly affecting Unit 4 on the second floor, though all these violations were abated by April 2019. Additional maintenance records show a furnace replacement in 2012, though this permit is now marked as expired. The building's location has had some minor street-level issues documented through 311 calls, including reports of illegal postings, abandoned vehicles, and debris, though these are typical urban disturbances and not directly related to building conditions.

There have been two recorded fire-related incidents, neither resulting in civilian injuries or suggesting building safety concerns. Historical routine inspections in 1998 and 2003 showed no violations, and the building's major systems appear to be receiving regular attention, with the most recent significant repairs focusing on safety and structural integrity. The property has maintained compliance with San Francisco's seismic retrofit requirements, completing the mandatory improvements required for its Tier 3 designation.
