425-429 Duboce Ave, San Francisco, CA 94117

The three-story multi-family residential building at 425-429 Duboce Avenue, owned by Mark J Magner Sprt Prpt Tr, was constructed in 1905 and contains three units. The property has undergone several significant improvements over the past decades, with the most substantial being a seismic retrofit completed in 2017 costing $118,000, which included foundation upgrades, shearwall installation, and anchor bolt improvements. Other recent major works include the replacement of four old Federal Pacific electrical panels with grounding in 2021, a voluntary new fire alarm system installation in 2013, and reroofing work in 2013.

The building has experienced various maintenance and safety improvements, including the replacement of rotted structural elements in 2011 and a bathroom/kitchen remodel in 2005. Notably, in 2011, the building underwent a series of corrections in response to multiple violations related to fire safety and security, which were all abated by June 2011. These violations included issues with weatherproofing on siding, exterior door security, fire extinguisher tagging, and egress obstruction.

While there have been some recent 311 calls regarding the property (2024-2025), mainly concerning garbage, debris, and parking issues, these are external to the building itself. A fire alarm system complaint was reported in 2024 but was determined to have "No Merit," and historical fire alarm complaints from 2009 and 2011 were similarly resolved. The property has maintained compliance with building codes since addressing the 2011 violations and continues to undergo regular maintenance and system upgrades to ensure resident safety and comfort.
