2011 19th Ave, San Francisco, CA 94116

The property at 2011 19th Avenue is a one-story, two-unit multi-family residential building located in the Parkside neighborhood, constructed in 1915 and currently owned by Timothy C. Chan. The building underwent significant legalization and safety improvement work from 2007-2011, including the legalization of a second unit that had existed since 1960, electrical system upgrades with a new panel and separate meters, and comprehensive plumbing improvements including new gas lines and a furnace replacement.

A notable building violation regarding illegal units was filed in 2006, which documented unapproved wiring, plumbing issues, and missing smoke detectors, though these violations were eventually abated by 2012. More recent concerns include a combustible materials violation in October 2023 that was resolved by November 2023, and a sewage back-up incident in July 2024. The building's infrastructure has received attention over the years, with foundation repairs completed in 2001 and various utility upgrades between 2008-2011.

Recent activity around the property has generated multiple 311 calls in 2024, primarily relating to parking violations and debris issues, though these do not directly impact building safety or habitability. Two tenant buyouts were recorded at the adjacent address (1991 19th Avenue) in 2019, with payments of $32,000 and $43,000 respectively. The property has maintained an active status with the San Francisco Planning Department, with two significant applications regarding the legalization of the second unit being processed and approved between 2008-2011, though records show both permits ultimately expired. The building's electrical and plumbing systems were notably modernized between 2008-2011, including separate utility services for both units, though some permits from this period are listed as expired rather than completed.
