405 21st Ave, San Francisco, CA 94121

The 405 21st Avenue property is a two-story, 6-unit multi-family residential building constructed in 1919, currently owned by Alfonso Chang. Recent activity at the property has primarily focused on commercial tenant improvements, with the most recent incident being an active violation case (opened August 6, 2024) regarding unpermitted restaurant remodeling work including a kitchen counter, flooring, and exterior signage installation for the Taj Indian Cuisine.

This violation has prompted multiple permit applications in late 2024 to address the unauthorized work, including kitchen counter installation ($27,000), kitchen hood installation ($3,500), and signage legalization. The building has a history of maintenance and compliance issues, most notably a cluster of fire safety violations in March 2002 that required remediation, including problems with fire escape ladders, fire alarms, and extinguishers, though these were all abated by June 2002. More recent concerns from 2010 involved dangerous conditions with rear exterior stairs, and the property has experienced periods of commercial vacancy, particularly noted in 2022.

The plumbing infrastructure appears to have been maintained, with a sewer line repair completed in 2017. Between December 2024 and January 2025, there have been reports of various street maintenance issues near the property, including graffiti and debris, though these are more related to public space than the building itself. Planning records indicate efforts to bring the restaurant space into compliance with various permit requirements, including an ABC referral for a Type 41 license that was approved.
