332-334 19th Ave, San Francisco, CA 94121

The two-story multi-family residential building at 332-334 19th Avenue in San Francisco's Central Richmond district, owned by Charge Partners LLC, was constructed in 1941 and currently contains five residential units. The property underwent significant modifications and compliance work between 2018-2020, including the installation of a new fire sprinkler system and related safety upgrades totaling over $97,000 to legalize a ground-floor unit and remove an unauthorized horizontal addition that had extended beyond the property's north boundary.

This work was part of the resolution of a Notice of Violation (NOV) issued in October 2012 regarding unpermitted construction, which was eventually abated in October 2020. The building's recent improvements include a complete re-wiring of one apartment in 2019, installation of a new sprinkler monitoring system in 2020, and updates to the furnace system.

Historical records show previous violations from 2001 related to unauthorized construction of a laundry facility, which was resolved within months. The property has undergone two roof replacements (1996-1997), and several permits have been issued over the years for various improvements, including a sidewalk permit in 2007. The legal review of the building's occupancy conducted in 2019 confirmed its classification as a two-story structure with two residential dwelling units, based on historical mapping and municipal records.
