1946-1950 Mason St, San Francisco, CA 94133

The 1946-1950 Mason Street building is a three-story, three-unit multi-family residential structure located in North Beach, built in 1908. The property has undergone several significant renovations and repairs over the past decade, with the most recent work occurring in 2022, including bathroom and kitchen ceiling repairs, and water line replacement. Previous major improvements included comprehensive unit remodels in 2012 (kitchens, bedrooms, bathrooms), electrical system upgrades in 2013 with the installation of 50 outlets and 200-amp service, and various plumbing improvements including drainage installations and heater replacements.

The building has experienced recurring maintenance challenges, particularly with plumbing issues evidenced by multiple complaints and repair works between 2012-2023. Notable incidents include a 2022 plumbing leak complaint involving wastewater issues between units 1946 and 1948, and a 2023 complaint regarding mold and broken appliances in unit 1948. Historical records show the building faced multiple violations in 2004 related to safety and maintenance issues, including problems with handrails, fire proofing, lead paint hazards, and security features, though these were officially abated in 2005.

Fire alarm systems have malfunctioned on several occasions between 2020-2021, but no injuries or significant incidents were reported. The property has been subject to regular routine inspections, with the most recent occurring in 2022, indicating ongoing monitoring of building conditions. Recent 311 calls suggest some ongoing external maintenance issues, including reports of debris, waste, and sidewalk accessibility concerns in the vicinity of the building, though these are not directly related to the building's internal conditions. The structure's age and history of renovation work suggest a mix of both maintained and requiring monitoring systems, with specific attention needed for plumbing infrastructure based on recurrent issues in this area.
