1854-1856 19th Ave, San Francisco, CA 94122

The two-unit residential building at 1854-1856 19th Avenue in San Francisco's Inner Sunset neighborhood has a history dating back to its 1950 construction as a two-story flats and duplex structure, currently owned by Robert Li and Judy Cheong. The property has undergone several improvements and faced some challenges over the years, with the most significant recent issues being recurring sewer vent problems, as evidenced by two reports in December 2023.

Historical records show notable permit activity, including a 1999 renovation that added storage rooms and a bathroom, though several older permits from the 1980s and 1996 related to kitchen improvements and exterior maintenance have expired. A significant incident occurred in 2005 when the building faced violations for an unauthorized wall sign installation on the north side, approximately 6 feet by 15 feet in size and featuring yellow, red, and white colors.

This violation triggered multiple Notices of Violation (N.O.V.) toward the mid-2005 period, though the issue was eventually resolved by August 2005. The building's maintenance history shows attention to various infrastructure needs, including responses to sidewalk and pavement defects (2018), tree maintenance (2017), and multiple parking enforcement issues on the adjacent streets between 2018 and 2023. The property has also experienced recurring sewer-related issues, with the most recent reports in December 2023 suggesting ongoing infrastructure challenges.
