531 Jackson St, San Francisco, CA 94111

531 Jackson Street is a three-story multi-family residential building with four units, constructed in 1911, and currently owned by 529 Commercial Street Associates. The building has undergone significant renovation work over the past decade, including major improvements to multiple units between 2014-2018, such as Unit #4's comprehensive bathroom and kitchen remodel (with a cost of $72,600), and Unit #3's renovation including new fire alarm systems and air conditioning installation. The ground floor has been improved with a substantial $200,000 restaurant renovation project in 2014-2015, which included electrical upgrades, new exhaust systems, and storefront improvements.

Notable electrical improvements include the installation of a new main panel with 6 meters (400amp 3p) in 2015, and various electrical system updates to individual units. The building's fire safety records show a concerning pattern of fire alarm system and extinguisher violations between 2021 and 2024, with the most recent fire complaint in November 2024 resulting in a violation. Multiple fire code violations related to maintenance of standpipes, alarm systems, building contact information, and sprinklers were issued in January 2025 and remain open.

Historical violations from July 2000 included issues with fire extinguishers, gas meter instructions, security viewers, and other safety compliance matters, though these were abated within a month. The property has experienced several fire-related incidents, though all were determined to be non-threatening (including false alarms and outside rubbish fire). Recent 311 calls from late 2024 and early 2025 indicate recurring issues with sidewalk debris and street cleaning matters around the property, though these are external to the building itself.
