575-577 Buena Vista Ave, San Francisco, CA 94117

The three-unit residential building at 575-577 Buena Vista Ave, owned by the Barbara J Korn 2005 Trust, is a two-story flats and duplex structure dating back to 1904 in the Buena Vista Park neighborhood. Over its history, the property has undergone several significant improvements, with the most recurring maintenance activity being roof work.

The building has required multiple roofing projects, with permits showing work in 1997 ($9,000), 2000 ($4,000), and 2002 ($4,000), though some of these permits expired without completion. A notable incident occurred in January 2002 when unauthorized roofing work was reported, with complaints about construction debris being improperly disposed of on neighboring property, though this violation was promptly abated within a week of being filed.

The property has seen various other improvements and maintenance work over the years, including the installation of 19 vinyl windows in 1996, front entry stair replacement in 1997, relocation of partition walls on the top floor in 1991, and exterior work including stucco removal and repairs in 1990. Residential unit upgrades have included a kitchen remodeling project in 1989, though this permit expired without confirmation of completion in the available records. The consistent pattern of roofing work, with multiple permits and costs incurred between 1990-2002, suggests this has been an ongoing maintenance focus for the property, while the prompt resolution of the 2002 unauthorized work incident indicates responsiveness to regulatory requirements when violations occur.
