870 Hampshire St, San Francisco, CA 94110

870 Hampshire Street is a two-unit, two-story multi-family residential building constructed in 1900 in San Francisco's Inner Mission neighborhood. The property, currently owned by the Carol Wlock Revocable Living Trust, has experienced several significant events in recent years, most notably a serious building fire in October 2023 that resulted in substantial damage requiring extensive restoration work. As of 2024, ongoing rehabilitation efforts include structural work to address foundation voids, complete interior restoration, and comprehensive electrical and plumbing system upgrades.

The electrical upgrades involve installation of new wiring, panels, and circuits throughout both units, while plumbing improvements include bathroom and kitchen renovations, gas pipe replacement, and new shower installations. A concerning incident occurred in April 2024 involving improper asbestos handling and inadequate site security during the restoration process, though this violation was abated within four days. Historical records show previous maintenance and renovation work, including back stairs repair in 2002, sewer line installation in 2008, and electrical rewiring in 2016.

A notable property dispute was documented in 2017 regarding an allegedly unauthorized stairwell structure that reportedly encroached on a neighboring property and hindered access for building maintenance, though the resolution of this matter is not recorded. The property has generated multiple 311 calls in recent years, primarily related to street cleaning and garbage issues in the vicinity, with the most recent concerns being reported in late 2024. While these external maintenance issues do not directly impact the building's habitability, they indicate ongoing neighborhood challenges. The building's recent fire damage and subsequent restoration work represent the most significant recent changes to the property, with substantial investment (over $190,000) in restoring the duplex following the incident, along with ongoing structural and systems improvements as of late 2024.
