20-22 Church St, San Francisco, CA 94114
The property at 20-22 Church Street is a two-story, four-unit multi-family residential building constructed in 1900, currently owned by Patrick Harty. The building has undergone several significant renovation attempts over the past decade, most notably a proposed vertical addition project initiated in 2016 to add a third story and two additional units, valued at $1.2 million. This project has faced multiple permit status changes, with recent shoring work permits totaling $70,000 filed in 2022 that ultimately expired.
More recent construction activity includes substantial work in mid-2023, encompassing complete unit remodels (including new furnaces), electrical rewiring, and bathroom renovations across all four units, with several associated permits showing significant investment in building improvements. The building's recent history has been marked by numerous code compliance issues and neighborhood concerns. Active complaints from 2024 highlight ongoing problems with building maintenance, vacant building status, and safety concerns, including reports of graffiti, debris, and security issues at the construction site.
A significant complaint filed in March 2023 noted potential structural concerns regarding adjacent property at #2 Church Street, which remains an active violation. The property has also experienced multiple lead hazard warnings and violations related to painted surfaces, though these were abated in 2016. Previous tenant buyouts occurred in 2016 and 2021, with compensation amounts of $52,333.16 for two tenants and $61,355 for one tenant, respectively. While the building has seen substantial investment in improvements and safety systems (including a fire sprinkler system installed in 2021), the recent history suggests ongoing challenges with construction site management and maintaining compliance with building codes and safety standards.
