780-790 Page St, San Francisco, CA 94117

The four-story, 14-unit multi-family residential building at 780-790 Page St in Hayes Valley, owned by 4051 Elm Street LLC, was constructed in 1912 and has undergone several significant safety upgrades in recent years. Most notably, in September 2023, the building received a comprehensive fire alarm system upgrade costing over $51,000 to comply with current San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas and an updated fire panel. The building has experienced recurring fire alarm system issues, with multiple false alarms and system malfunctions reported between 2023 and 2024, though fortunately none resulted in civilian injuries.

A carbon monoxide detector was activated with no CO detected in 2024. The property has addressed various maintenance issues over its history, including a 2016 repair of dry rot in exterior stairs and lightwells costing $4,500. In 2017, a mandatory soft-story retrofit permit was withdrawn, indicating this requirement was not pursued by the owner.

Historical records show regular routine housing inspections conducted in 1998, 1999, and 2005, with no significant violations noted in recent years. A cluster of recent 311 calls from 2023-2024 primarily relate to parking issues and street cleaning matters, indicating external urban challenges rather than building-specific problems. The most recent fire alarm system complaint from November 2024 remains open, though this appears consistent with the building's recent history of fire system adjustments and testing.
