821 Leavenworth St, San Francisco, CA 94109

821 Leavenworth Street is a 5-story, 19-unit multi-family residential building constructed in 1916, currently owned by 821 Leavenworth Street LLC. The building's safety systems have received recent significant attention, with two fire alarm system upgrades completed in late 2022 and early 2023, including the installation of low-frequency sounders and AES monitoring modules. A backflow prevention assembly was installed in 2018, indicating attention to water safety systems.

The building has undergone several major improvements over the past two decades, including a reroofing project in 2001, marble slab replacement in the entryway, and multiple electrical upgrades such as security camera installations in 2016 and emergency lighting improvements in 2006. The property has experienced periodic fire safety-related incidents, including multiple false alarms, smoke detector activations, and one incident involving elevator rescue, though none resulted in injuries or fires. Historical records show several building violations in 2005-2006 related to fire safety equipment and gate maintenance, all of which were resolved within a month.

The building underwent a seismic retrofit in 1996, enhancing its structural integrity. Recent maintenance activities include regular updates to security systems and fire safety equipment, though there have been some recent concerns about building access security (e.g., front gate speed). The surrounding area has experienced recurring street cleaning issues as documented in recent 311 calls, though these are external to the building itself and relate to the urban environment.
