850-852 York St, San Francisco, CA 94110

The two-unit, two-story residential building at 850-852 York Street in the Inner Mission, owned by the Joan Caldwell Living Trust, is a well-maintained structure dating back to 1900. The property has undergone several significant improvements over recent years, with the most substantial being a complete re-roofing project costing $20,180 in 2015, foundation bolt installation in 2016 for seismic safety ($1,500), stair replacement and garage door upgrade in 2017 ($20,000), and rear door replacements in 2018 ($4,500).

A horizontal addition was completed in 1990, and there was an isolated housing inspection complaint in 2012 regarding window work and paint chips that has since been resolved. More recent issues affecting the property primarily relate to external environmental factors, including recurring concerns about tree root damage to the sidewalk, with the most recent reports in April 2023 and August 2024 noting opened cases with tree roots lifting the sidewalk.

There have been multiple reports of abandoned debris and garbage on the street near the property between 2021 and 2024, including two instances of discarded mattresses in June 2024. A missing side sewer vent cover was reported in May 2021 and remains open as of the latest records. The building's maintenance history suggests regular upkeep of structural and safety features, with no significant internal building complaints or safety violations on record in recent years.
