810 Masonic Ave, San Francisco, CA 94117

810 Masonic Avenue is a three-story, 6-unit multi-family residential building constructed in 1909 and currently owned by 810 Masonic LLC. The building has undergone several significant improvements over the past decades, with the most recent major work focusing on safety upgrades. In 2021, the building completed a fire alarm system upgrade to comply with San Francisco's new regulations, following a pattern of fire safety concerns with multiple alarm system-related complaints between 2008 and 2016 that were all marked as "Condition Corrected." The property has seen substantial maintenance of its windows, with the most recent work in 2018 involving the replacement of 15 front visible windows with high-quality Marvin Ultimate aluminum clad double hung windows, following a 2011 project that replaced 16 non-visible windows with vinyl double pane equivalents.

Other significant improvements include HVAC upgrades with the replacement of three console heaters in 2013, fire safety improvements including fire escape maintenance in 2003, and plumbing work. The building has experienced some structural and maintenance issues in the past, including water damage repairs in 1997 and multiple roofing projects, though these were completed successfully. The property has undergone routine safety inspections in 2003 and 2017, with all identified issues being resolved.

Recent external maintenance concerns have primarily involved sidewalk cleanliness and graffiti issues, with several 311 calls in 2023-2024 regarding these matters. However, these exterior issues do not directly impact the building's internal systems or resident safety. The property's maintenance history demonstrates regular upkeep and compliance with safety regulations, with most recent work focusing on modernizing systems and addressing any safety concerns as they arise.
