433-439 Linden St, San Francisco, CA 94102

The 4-unit, 2-story multi-family residential building at 433-439 Linden Street in Hayes Valley, owned by the Thomas Simone Estate Of, has been standing since 1900. The property has undergone several significant improvements over the years, with the most recent notable work being a federal pacific electrical panel upgrade completed in April 2023. In 2007, a complete reroofing project was undertaken at a cost of $18,810.

The building faced several fire safety violations in late 2005, which were all resolved by December 19, 2005. These violations included issues with combustible storage, fire proofing materials, and gas utility preparation requirements. The building received routine safety inspections in 2018 and 2010, with no active violations noted from these inspections.

The property's maintenance history shows attention to safety improvements, particularly in 2005 when the building achieved one-hour fire separation in basement and storage room ceilings. While the building has generally maintained compliance with safety requirements, there have been ongoing street-level maintenance issues in the immediate vicinity, as evidenced by multiple 311 calls regarding street cleaning and waste removal from 2020 through 2024. These external maintenance issues appear to be promptly addressed by city services, though they do represent an ongoing concern in the building's immediate neighborhood.
