1831 19th Ave, San Francisco, CA 94122

The Lin Family Trust owns this two-unit, two-story multi-family residential building located at 1831 19th Avenue in San Francisco's Central Sunset neighborhood. Built in 1948, this flats and duplex structure has undergone several significant maintenance and improvement projects over the past decade. Most notably, in 2018, the property underwent substantial exterior work including stucco replacement on the front façade with retention of original details, though an electrical service upgrade to 200 amps was ultimately cancelled.

The building also received a new roof that same year, with these improvements totaling approximately $24,000. In 2011, essential infrastructure maintenance was performed with a sewer repair completed the same year as a street space and sidewalk permit was issued. The property's maintenance history shows regular upkeep, though there was a brief period of concerns regarding roof access and a missing vent cover in early 2022.

The building has experienced several parking-related issues in recent years, with three documented cases of blocked driveways between 2018 and 2020, though all were resolved through appropriate enforcement actions. A noise complaint regarding amplified sound was filed in November 2021 and resolved through normal departmental procedures. Other minor issues included a non-offensive graffiti incident reported in 2013, which was also resolved. The most recent significant building work involved stucco replacement and electrical upgrades in 2018, with no major repairs or violations recorded in the past five years beyond routine maintenance and infrastructure support.
