443-445 19th Ave, San Francisco, CA 94121

The two-unit residential building at 443-445 19th Avenue in the Central Richmond neighborhood, owned by the Alan & Rachel Wong Revocable Trust, is a two-story flats and duplex structure built in 1916. The building's maintenance history shows several significant structural improvements, including foundation stabilization work in 2001 involving chemical grouting recommended by a soil engineer (though this permit has since expired), and the installation of 60 foundation bolts in 1992. More recent maintenance includes a reroofing project completed in 2017 costing $8,700.

The property has experienced three fire-related incidents on record, including a confined cooking fire in 2018, a smoke scare, and a false alarm, though fortunately none resulted in civilian injuries. The building has had several infrastructure and maintenance issues in recent years, particularly involving tree root damage to the sidewalk, which remains an open concern as of October 2023. A 2022 rent board case was successfully resolved with an exemption approval.

The property management has responded to various municipal service calls, including sidewalk cleaning and graffiti removal, most of which have been resolved. Recent activity in the vicinity has mostly involved parking-related issues, with three enforcement calls in 2024. While there have been multiple 311 calls regarding street conditions and maintenance, these appear to be typical urban neighborhood issues rather than building-specific problems. The presence of foundation work from the 1990s and 2000s, along with the 2017 reroofing project, suggests proactive maintenance of major building systems, though some historical permits are listed as expired.
