447 7th Ave, San Francisco, CA 94118

The property at 447 7th Avenue in the Inner Richmond is a two-story, 4-unit multi-family residential building constructed in 1923, currently owned by the Carson & Irene Lee Yu Revocable Trust. The building has undergone several significant renovations over the past two decades, including comprehensive kitchen remodels in all four units between 2002-2004, electrical upgrades, and various maintenance works.

Most notably, a routine inspection in 2015 revealed multiple fire safety issues that were subsequently addressed, including the installation of fire sprinklers, replacement of fire extinguishers, and improvements to lighting and signage. The building experienced some plumbing issues in 2015, requiring the replacement of a leaking water heater, which was completed in 2016 along with other repairs. The property has maintained regular housing inspections through Housing Inspection Services, with all identified violations being promptly addressed and abated.

Recent maintenance activities can be traced through building and plumbing permits, including a street space permit in 2016. The surrounding area has experienced typical urban challenges as evidenced by 311 calls from 2020-2024, mostly related to street cleaning issues such as garbage, debris, and specific incidents of human waste on sidewalks, though these external factors do not directly impact the building's internal conditions. The building's documented history shows consistent attention to maintenance and compliance with housing codes, with particular attention paid to fire safety systems and unit improvements over the years.
