4950 California St, San Francisco, CA 94118

The 12-unit, 3-story multi-family residential building at 4950 California Street in the Lake-Presidio neighborhood, owned by Antonio & Rita Castellucci, has been in operation since 1923 and is currently facing several notable compliance and safety issues. Most pressing among these is the building's non-compliant status with the mandatory Soft Story Retrofit program (as Tier 4) established in 2018, for which no permit application has been submitted. More recently, there have been serious window safety concerns, with two active complaints in 2022 regarding a dangerously dangling window sash on the 3rd floor that remains unresolved as of October 2023.

The building's fire safety systems have required ongoing attention, with past violations related to exits, fire escapes, and alarm systems noted between 2018-2024, though most have been corrected. The property experienced a significant cluster of fire safety violations in 2003 that were subsequently abated in 2004, including issues with self-closing doors, fire proofing, smoke enclosure doors, combustible storage, sprinkler requirements, and fire escape maintenance. Recent improvements include a major renovation in Unit 3 ongoing as of August 2024, encompassing kitchen and bathroom updates with associated electrical and plumbing work.

The building's mechanical systems have seen attention, with a new steam boiler installation and flue vent replacement completed in 2019 following a Notice of Violation. Multiple 311 calls regarding garbage, debris, and public health issues have been recorded between October 2024 and January 2025, suggesting some ongoing maintenance and cleanliness challenges in the immediate vicinity. The property has undergone routine inspections over the years, with the most recent documented in 2008, and has maintained basic compliance with housing codes, though the outstanding Soft Story Retrofit requirement remains the most significant regulatory gap.
