851 45th Ave, San Francisco, CA 94121

The two-unit residential building at 851 45th Avenue in San Francisco's Outer Richmond neighborhood is a one-story structure built in 1948, currently owned by Kayvon Shakeri. The property has undergone significant improvements and infrastructure upgrades, particularly between 2016-2018, including the installation of a comprehensive fire sprinkler system with 33 heads ($20,000), complete electrical rewiring with 200-amp service upgrade ($20,000), plumbing renovations including two kitchens and four bathrooms ($12,000), and the addition of radiant heating systems with new boilers ($15,000).

A notable violation was recorded in October 2017 regarding improper concrete work in the front yard, which was subsequently addressed by restoring required landscaping and permeable surfaces ($2,500). The building has experienced two sewage backup incidents in recent years (2020 and 2024), with the most recent occurring in January 2024.

Multiple 311 calls regarding debris and garbage removal were logged between July 2024 and September 2024, though these do not necessarily reflect on the building's condition. The most recent notable modification was an attempted interior remodel to improve unit division and add a rear deck, though this permit is currently marked as "Closed - Cancelled." The building has a documented history of both routine maintenance and significant upgrades, with particular attention paid to fire safety systems and overall building infrastructure improvements during the 2016-2018 period. Recent maintenance issues appear to be primarily related to exterior cleaning and minor plumbing concerns, with no current active building violations on record.
