Augrented Insights Report

The Chow Family Trust property at 1501-1515 Mason Street is a 10-unit, 3-story multi-family residential building with retail space, constructed in 1907 in San Francisco's Russian Hill neighborhood. Recent building inspections have revealed ongoing maintenance issues, with the most current violation filed in August 2024 citing peeling paint, which followed a pattern of similar violations dating back to 2011.

The building has a documented history of paint-related concerns, including multiple complaints about lead paint, with the latest complaint in March 2024 describing inadequate maintenance and blighted exterior conditions. Structural and safety concerns have been recorded over the years, including requirements for handrails, stair repairs, and window replacements, though the majority of these violations have been marked as "not active" following their abatement in December 2024. The property has undergone routine inspections approximately every 2-3 years since 2000, with specific compliance issues noted in several inspections.

Recent 311 calls from 2023-2024 have documented various maintenance matters, including missing sewer vent covers and exterior graffiti, though these are generally not directly related to building habitability concerns. Planning records indicate past activity related to garment manufacturing use on the property, with approvals granted for transfers and terminations of related permits, suggesting historical commercial use of part of the building beyond typical residential occupancy. The most recent complaints and violations were addressed and abated in December 2024, though an active complaint regarding common areas was filed in March 2024 and remains open as of the latest records.
