251 Parnassus Ave, San Francisco, CA 94117

Located in the Parnassus/Ashbury Heights neighborhood, 251 Parnassus Avenue is a 3-story, multi-family residential building constructed in 1925, containing 18 units and currently owned by Pearl Street Ventures LLC. The building has undergone several significant improvements over the years, with the most notable being the successful completion of a mandatory soft-story retrofit in 2016 (as a Tier 2 building) which brought the structure into compliance with seismic safety requirements. The property has experienced recurring boiler permit issues, with multiple violations filed between 2010 and 2020 regarding improper boiler operation permits, though these issues were eventually resolved.

More recent maintenance and upgrades include a new backflow system for the boiler (2018), an electrical system upgrade to 400 amp service (2003), and routine fire safety inspections in 2021 that resulted in corrected conditions for alarm and sprinkler systems. The building's maintenance history shows regular upkeep, including window replacements in 2014 and various plumbing upgrades. While there have been occasional issues, such as a 2013 construction noise complaint and multiple garbage and debris incidents reported in 2024 (all resolved), these have generally been addressed promptly.

Three notable fire safety incidents were recorded, including a gas leak, steam pipe rupture, and water leak, though none resulted in civilian injuries. The property has also received periodic routine inspections and has maintained compliance with building code requirements, as evidenced by a 1984 completion of necessary code updates and more recent infrastructure improvements. While there have been some concerns with sidewalk cleanliness and graffiti on property, these are primarily external to the building itself.
