1806-1812 Mason St, San Francisco, CA 94133

The three-story, six-unit multi-family residential building at 1806-1812 Mason Street in North Beach, owned by Ken Faye Lim Separate Prope, was constructed in 1907. The property has undergone several significant safety upgrades, most notably in 2023 when the entire fire alarm system was replaced at a cost of $43,100 to comply with current fire codes, including new smoke detectors, pull stations, and monitoring modules. The building has experienced recurring safety and maintenance issues, with a particularly significant cluster of violations recorded in late 2016.

These violations included problems with plumbing fixtures (toilets, sinks), lighting, stairs, landings, windows, and emergency systems, as well as building code compliance matters. All these violations were officially abated by June 2017. During this period, multiple fire safety concerns were also documented, including issues with fire extinguishers, alarm systems, and roof access, resulting in several fire code violations.

The building's maintenance history shows attention to structural elements, such as work on the rear stairs in 2004 ($5,000 repair) and various street space permits over the years. While there have been periodic maintenance complaints through 311 calls, focusing primarily on street cleaning and parking issues in recent years, no major building safety violations have been reported since the comprehensive 2016 citation. The property's fire safety record indicates multiple false alarms and malfunctioning detector activations between 2016 and 2020, though no civilian injuries were reported in any incidents. The most recent building permit (2023) suggests ongoing commitment to maintaining fire safety systems, despite the building's age and historical maintenance challenges.
