1100 Valencia St, San Francisco, CA 94110

The two-unit mixed-use building at 1100 Valencia St, located in San Francisco's Inner Mission district, has undergone significant and concerning changes since its construction in 1907. Most recently, in June 2023, the building experienced substantial damage when a vehicle crashed into its front corner, prompting emergency responses and resulting in the temporary evacuation of two tenants from the residential portion. This incident, along with previous unauthorized construction work and fire safety violations, has led to multiple active building violations under Section 110A, Table1A-K of the San Francisco Building Code.

Prior to this incident, the property was embroiled in a series of construction-related controversies, including a May 2021 violation for unauthorized removal of fire protection systems and subfloor materials exceeding permitted work, which resulted in multiple Notices of Violation (NOVs) and monitoring fees. The building has seen various attempted improvements and modifications over the years, including the installation of an ADA-compliant bathroom in 2019, electrical upgrades, and fire safety equipment replacement. However, many permits indicate incomplete or expired work, including a 2020 permit for soft demolition and structural observation that prompted multiple complaints.

The ground floor commercial space, which has a complicated history of alleged unauthorized use as co-working office space and artist studio/bar, has been reportedly vacant for extended periods, with multiple vacant storefront complaints filed between 2019 and 2020. Current planning records indicate ongoing review of the property, particularly concerning its commercial space usage and recent damage repairs. The building's maintenance history shows regular issues with graffiti and debris on the property, as evidenced by numerous 311 calls throughout 2024, though these are more related to exterior conditions than structural concerns.
