425 Lyon St, San Francisco, CA 94117
The property at 425 Lyon Street is a 4-unit, 2-story multi-family residential building constructed in 1900, currently owned by Mt Hermon Missionary Baptist Church. The building has experienced several significant maintenance and safety issues over the past decade, with the most serious concerns emerging between 2014-2019, including multiple violations related to rodent infestation, unauthorized combustible storage, and a dilapidated rear structure that was deemed uninhabitable in 2015. Numerous building violations were filed in 2016 and earlier in 2014, though all were officially abated by July 2019.
The building underwent substantial renovation work in 2006, costing $175,000, which included remodeling bathrooms and kitchen, replacing windows and doors, and other improvements. Additional repairs have been documented through various permits, including electrical rewiring in 2005, bathroom/kitchen renovations, and structural repairs to address dry rot in 2017. Recent activity around the property (January 2025) has primarily involved multiple reports of encampments and street cleaning issues, though these appear to be related to the property's vicinity rather than the building itself.
There are also historical complaints from 2012 regarding unauthorized construction work and concerns about the conversion of the building from two to six bedrooms without proper permits, which were addressed at the time. The property had its only reported tenant buyout in November 2016, involving a payment of $24,500 to one tenant at the adjacent address (421 Lyon Street). While many past violations have been resolved, the building's history shows a pattern of maintenance issues and regulatory compliance challenges, particularly regarding the rear structure and unauthorized modifications.
