21 Winfield St, San Francisco, CA 94110

The two-unit residential building at 21 Winfield Street in Bernal Heights is a two-story flats and duplex structure built in 1902, currently owned by Crandall SF Family Trust. The property has undergone several significant maintenance and improvement projects over the past two decades, with the most recent major works including a $15,675 re-roofing project and $20,000 front stairs repair in 2019.

An extensive renovation took place in 2003, covering both units and the garage/basement, including kitchen remodeling, window replacements, and comprehensive electrical upgrades with new service installations. The building has experienced multiple infrastructure and maintenance issues in recent years, particularly regarding external elements. There are currently three open 311 cases from 2023-2024 related to property concerns: one regarding damaged trees affecting both sidewalk and property conditions, one about sidewalk blockage from private vegetation, and one relating to a sidewalk defect (collapsed sidewalk).

Historical documentation shows consistent attention to structural elements such as stairs and sidewalks, with particular focus on safety features like railings and emergency access points. While the building has maintained basic structural integrity through regular maintenance, the recent concentration of issues around the exterior infrastructure suggests ongoing challenges with the building's immediate surroundings. The property's permit history indicates proper legal channels have been used for major works, though no recent interior upgrades or improvements have been documented since the 2019 re-roofing and stair repairs.
