1351 Mason St, San Francisco, CA 94133

The 13-unit, 3-story apartment building at 1351 Mason Street in Nob Hill, owned by Michael Gong & Amy Lui Revo, has undergone significant recent improvements totaling over $500,000 in permitted work since 2022. The property, built in 1911, successfully completed its Mandatory Soft Story Retrofit Program requirements as a Tier 3 building, achieving Certificate of Final Completion and Fire Code compliance. Recent major projects include the installation of three ADUs in 2024, comprehensive renovations of multiple units (2, 3, and 4) in 2023-2024 involving kitchen and bathroom remodels, window replacements, and associated mechanical systems upgrades.

The building has maintained active fire safety compliance, with recent permits for upgrading the fire alarm system and installing a new fire sprinkler system. Historical fire safety issues were addressed promptly, with confirmed corrections in 2018, 2019, and 2023, though a recent fire alarm system upgrade permit was issued in November 2024. The building's maintenance record shows consistent attention to infrastructure improvements, including a complete reroofing in 2022 and significant plumbing and electrical upgrades throughout. While there have been several building violations and complaints over the years, including issues with fire extinguisher maintenance and heating system requirements in 2000-2008, these were typically resolved promptly.

A notice of violation for illegal short-term rentals was issued in 2021, but this was subsequently abated. Recent complaints in 2024 regarding fire extinguisher tagging and system compliance were also promptly addressed and abated. The property has experienced some construction-related disruption as evidenced by noise complaints in 2017 and 2020, but these issues appear to have been temporary. The building's ongoing maintenance and improvement history, particularly the recent focus on fire safety upgrades and compliance with soft-story retrofit requirements, demonstrates active management of the property's structural and safety systems.
