433 Arguello Blvd, San Francisco, CA 94118

The property at 433 Arguello Blvd is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by the Lee & Kwong Family Trust. The building has undergone several significant renovations and modifications over the past decades, with the most recent major work including a 2016 reroofing project costing $12,000. In 2014, modifications were made to enclose space under existing sunrooms with sliding windows for storage purposes.

A substantial renovation occurred in 2012, which included installing a full bathroom on the ground floor, followed by comprehensive electrical and plumbing work in the basement area. The property previously faced serious compliance issues in 2007 when a violation was filed regarding an illegal basement unit conversion, which included multiple life safety concerns such as inadequate ventilation, improper wiring and plumbing, and non-compliant ceiling height. This situation was resolved by September 2007 when the illegal unit was restored to storage rooms and garage space.

Recent years have seen multiple maintenance and infrastructure issues, particularly regarding sewer problems, with four sewage backup incidents reported between 2020 and 2021, all of which were resolved through City services. The building has also experienced some minor external issues, including graffiti incidents in 2020 and 2022, and there have been several parking-related complaints in recent years. While the building's major systems have received attention over the years (including window replacements and kitchen/bathroom remodels in the late 1990s), the property has not pursued the previously proposed development to replace the two-family dwelling with a five-unit building, which was cancelled in 1987. The only active ownership is under the Lee & Kwong Family Trust with most recent permits reflecting routine maintenance and upgrades rather than major structural changes.
