20 Franklin St, San Francisco, CA 94102

20 Franklin Street is a 72-unit, 6-story multi-family residential building constructed in 1917, currently owned by Mercy Housing California XV. The property has experienced significant maintenance and safety issues in recent years, with the most pressing concerns being a recurring heating system failure between 2023-2024, which reportedly required residents to use space heaters, and a series of water-related problems including plumbing failures in 2023-2024. Recent complaints as of November 2024 indicate multiple maintenance issues including broken doors, plumbing problems, electrical outages, elevator malfunctions, and ceiling damage from leaks. The building's safety systems have also been a concern, with multiple fire code violations reported between 2023-2025 related to alarm systems, sprinkler systems, and blocked exits.

A notable recent incident occurred in July 2024 when a car crashed into the building, though repairs were completed by October 2024. The building has undergone several significant infrastructure improvements over the years, including a major reroofing project in 2018 costing approximately $98,375, and the replacement of multiple utility systems including boilers and water piping. In 2024, work was initiated to repair a brick ponywall and storefront, along with ongoing maintenance like window caulking and downspout replacement. A comprehensive upgrade project is currently proposed (though on hold) that includes seismic strengthening, mechanical, electrical, and plumbing upgrades, security improvements, and exterior repairs to address deferred maintenance.

The building's historical significance as a contributing structure to the Market Street Masonry Historic District is noted, and it is currently designated as providing 100% affordable housing for people living with AIDS. The property has a history of internal maintenance issues dating back to 2007, when violations were issued for various interior problems including heating system failures and lead paint concerns. More recent complaints indicate persistent problems with building systems and infrastructure, particularly regarding the heating system and dated plumbing. While some historical violations were resolved by 2007, the building has experienced recurring issues with basic services and safety systems. The property has maintained its use as multi-family residential housing since its construction, and the recent permit activity suggests ongoing efforts to address building maintenance and safety concerns, though these have been inconsistently completed or followed through.
