455-457 19th Ave, San Francisco, CA 94121

The two-unit residential building at 455-457 19th Avenue in the Central Richmond district is a two-story duplex constructed in 1921, currently owned by the Tim & Linda Wong Trust. The property has a history of significant remodeling and compliance issues, particularly regarding unit conversions and unauthorized modifications. In the late 1990s, there was a proposed horizontal addition with an estimated cost of $115,000, followed by several building permit modifications between 2002-2003 involving bathroom relocations and hallway modifications.

A notable compliance issue occurred in 2001 when illegal unit appliances were documented, including a stove and refrigerator in the garage level, leading to enforcement actions. In 2014, a similar complaint was filed regarding illegal unit conditions. The building has also experienced unauthorized construction work, as evidenced by a 2007 complaint about an unpermitted 12-foot ground level extension, though this was resolved within a month.

More recently, the property has been subject to numerous parking enforcement issues, with eight documented instances of blocked driveways between March 2023 and September 2024, resulting in several citations being issued. These parking enforcement calls indicate ongoing challenges with vehicle access to the property, though they are not directly related to the building's structural or safety conditions. The building's permit and complaint history suggests a pattern of unauthorized modifications and compliance issues, though many of these matters appear to have been resolved through subsequent permits or enforcement actions. As of October 2023, there are no active building violations or permit applications on file, indicating current compliance with building regulations.
