430 19th Ave, San Francisco, CA 94121

The two-unit residential building at 430 19th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1914 and currently owned by the Ng Family Trust.

The most significant recent improvement to the property was completed in early 2023, involving the replacement of 16 windows at a cost of $28,900, including eight street-facing windows made of wood alum-clad material and eight rear windows made of vinyl, with no size changes and improved energy efficiency (U-factor < 0.30). The building's maintenance history shows attention to public spaces in 2010 and 2015 with permitted work related to street space and sidewalk repairs, though these were minor projects with minimal costs.

The property has generated two documented complaints in recent years: a parking enforcement issue in May 2023 involving a vehicle parked on the sidewalk (which could not be located by responding officers), and an ongoing tree-related concern from November 2021 regarding root damage to the sewer system, which is currently under review by the Department of Public Works. While the tree issue remains open, it is notable that no immediate safety or habitability concerns have been recorded through the 311 system or other official channels, and the recent window upgrade represents a significant improvement to the building's envelope and energy performance.
