2520-2522 Sutter St, San Francisco, CA 94115

The two-unit residential building at 2520-2522 Sutter Street in Lower Pacific Heights, owned by Daniel Yang, has undergone several significant renovations and faced some maintenance challenges since its construction in 1982. Recent major improvements include a complete reroofing project in 2021 (cost: $22,000), bathroom additions and remodels in 2021 ($25,000), and comprehensive electrical rewiring with new features in 2021. The property has received attention to its plumbing infrastructure, with new water mains installed for both units in 2022, and multiple bathroom renovations including gas pipe replacements.

Historical improvements from 2008-2009 included kitchen and bathroom remodels in both units, window replacements (with some permit issues that were ultimately resolved), and dry rot repairs in 2002. The building's maintenance history shows periodic updates and repairs, including central heating system installations and compliance with various building codes. While there have been some past issues that required attention, including a sewer backup incident in 2006 and a few fire department responses (mostly for false alarms or system activations), none of these events indicate ongoing safety concerns.

Recent 311 calls from 2023-2024 have primarily related to external issues such as tree maintenance and parking enforcement rather than building-specific problems. A building inspection complaint regarding mold and mildew was recorded in January 2024 and marked as accepted, warranting attention to potential moisture issues. The property has maintained its designation as a flats/duplex building, with no significant changes to its unit size or structure.
