233-235 Madrid St, San Francisco, CA 94112

The three-story multi-family residential building located at 233-235 Madrid Street in the Excelsior neighborhood, owned by Ping Ping Chen 2012 Living Trust, has undergone several significant modifications and improvements since its construction. The property, which contains two units, has seen substantial renovations between 2012-2018, including the legalization of a second unit in 2015 (2 bedrooms, 2 baths, 1 kitchen, 1 living room), conversion of storage into living spaces in 2014, and various compliance-related improvements to address violations from 2007. The building has received comprehensive updates to its systems, including electrical rewiring, plumbing upgrades (new sewer, gas, water pipes), and HVAC improvements with a new furnace installation in 2013.

Multiple building permits were properly filed and completed for these improvements, with the most recent being an administrative permit from 2018 to correct previous documentation. Historical records indicate some concerning patterns related to building safety and maintenance, particularly during 2020 when complaints were filed regarding dangerous work conditions and pest problems. Fire safety complaints have been recorded in 2007 (blocked exits), 2008 (alarm systems), and 2012 (blocked exits), though most were either found to have no merit or were corrected promptly.

The building's recent history shows ongoing maintenance issues, with several 311 calls in 2024-2025 primarily related to parking violations and one noise complaint, as well as a property damage report filed in January 2025. While most major renovation work has been properly permitted and completed, there have been some instances of work being performed outside of permit scope, as noted in complaints from 2013. The property's documentation shows efforts to bring the building into compliance with local regulations, particularly regarding unit legalization and system upgrades, though some historical violations from 2007 related to unauthorized additions appear to remain as "Active" in the records.
