2146-2148 Mason St, San Francisco, CA 94133

The two-unit residential building located at 2146-2148 Mason Street in North Beach is a two-story flats and duplex structure built in 1955, currently held in the Chew Family Living Trust Th. The property has undergone several notable improvements over the years, with two significant updates on record: a stairway lift installation costing $21,200 in 2000 (though this permit has since expired) and a 200-amp electrical service upgrade scheduled for November 2024.

The building's maintenance history includes attention to sidewalk infrastructure, with a resolved issue regarding a missing side sewer vent cover in October 2021. The property has experienced a recurring pattern of parking-related incidents in recent months, with three driveway blocking incidents recorded in September 2023 alone, resulting in one vehicle being towed.

Other parking enforcement cases and sidewalk maintenance issues have been documented, including a resolved case of illegal postings in April 2023, an instance of human or animal waste on the street in October 2022, and routine street cleaning matters such as the removal of loose garbage and an abandoned Christmas tree in early 2022. While these events represent typical urban maintenance challenges, they have all been addressed through appropriate channels. The most recent building permit activity suggests ongoing infrastructure improvements, with particular attention to accessibility (historically through the stairway lift) and electrical systems, as evidenced by the upcoming electrical service upgrade.
