2147-2151 Mason St, San Francisco, CA 94133

The three-unit, three-story multi-family residential building at 2147-2151 Mason Street in North Beach, owned by Alderman Thomas William & W, has undergone significant renovations and improvements since its construction in 1909. Recent work includes a kitchen remodel in 2023 involving structural modifications and cabinet replacement, following a 2022 kitchen cabinet and appliance update, and a major electrical upgrade in August 2024 involving relocation of the federal pacific panel and rewiring.

The building has seen consistent maintenance and improvements over the years, including a bathroom remodel in 2019 (with associated plumbing and electrical work), window replacements in 2019, and historical maintenance such as reroofing in 2007 and siding repairs in 2006. The property's inspection history shows some regulatory oversight, including a fire safety violation in 2006 regarding fire extinguishers, which was promptly resolved, and a building complaint in 2005 regarding unpermitted remodeling.

While these issues were addressed, there has been a notable increase in recent sanitation concerns in the vicinity of the building, with multiple reports of garbage, debris, and waste (including human waste) on surrounding streets in 2024, suggesting some challenges with street maintenance in the immediate area. Two fire-related incidents have been recorded: a contained cooking fire and a CO detector activation, neither resulting in civilian injuries. The building's permit and improvement history demonstrates ongoing investment in maintenance and upgrades, with particular attention to updating kitchen and bathroom facilities, electrical systems, and general infrastructure.
