425-431 Linden St, San Francisco, CA 94102

The property at 425-431 Linden St is a two-story, four-unit multi-family residential building located in Hayes Valley, built in 1925 and currently owned by Peter L. Holden. The building has undergone several significant improvements over the years, with the most recent attempt at renovation being a cancelled permit from June 2023 for kitchen and bathroom updates in units 425, 427, and 429, along with front window replacements.

A major renovation project was successfully completed in 2008, which included the installation of a new 150-amp electrical service with five meters, new garage assignments, and comprehensive electrical updates using a "cut & slice" method. The building has also seen significant infrastructure upgrades, including the installation of three tankless water heaters in 2008, replacement of all four units' electrical systems, and the addition of a solar electric system in 2004 consisting of eight panels and an inverter. The property has maintained compliance with several routine safety inspections, with minor violations such as the January 2011 fire extinguisher issue being promptly addressed within one month.

Earlier compliance issues from 2009 were resolved through necessary repairs including ceiling patching, smoke alarm installations, and proper vent installations. The building underwent a condo conversion approval process, allowing for potential individual unit ownership. More recently, there have been multiple parking-related incidents recorded through 311 calls in late 2023, primarily concerning blocked driveways, though most of these cases could not be validated by responding officers. The property's maintenance history shows a pattern of proactive improvements, though the cancelled renovation permit from 2023 is notable as it suggests ongoing interest in building upgrades.
