645-647 Broderick St, San Francisco, CA 94117

The two-unit residential building at 645-647 Broderick Street, owned by Gloria Chen, has a significant history of structural issues and building code violations dating back to 2007. The 1900 flats and duplex structure, located in Park North, underwent multiple permitted repairs in 2007-2008 including roof repairs, deck tiling, floor repairs, and concrete slab work in both the garage and basement areas, with a total cost exceeding $40,000. However, most of these permits expired without required inspections, leading to multiple active Notices of Violation (NOV) under San Francisco Building Code Section 106A.4.4, specifically relating to permits #200707187129, #200710196017, #200711208658, and #200802154937.

The building has a documented history of short-term rental violations, with complaints in 2009 and 2014 regarding illegal vacation rental use, including allegations of continuous Airbnb operations, tenant disturbances, and waste management issues. These violations resulted in one NOV being marked as "Abated" in 2013, though related active violations remain on record. More recently, there has been ongoing concern about illegal short-term rental activity, with an alleged "illegal tourist hotel" status recorded in Planning Records. The property has also experienced periodic parking enforcement issues, with multiple calls relating to blocked driveways and sidewalk parking between 2020 and 2023, though most were resolved without citations.

However, one citation was issued in April 2021 for driveway blocking. The most recent building inspection request was filed in August 2024 and marked as invalid due to an incorrect address. While there have been numerous improvement attempts and repairs documented through permits, the persistent pattern of expired permits and building code violations suggests ongoing maintenance compliance challenges. The property continues to show signs of unauthorized use patterns through periodic enforcement actions.
