1336 20th Ave, San Francisco, CA 94122

The two-unit residential building at 1336 20th Avenue in the Central Sunset neighborhood is a two-story flats and duplex structure built in 1925, currently owned by Jackson & Mew Yee Wong Hom. The property has a concerning history of maintenance issues, particularly during 2000 when multiple housing complaints were filed within a week period, including reports of mold and mildew in multiple rooms and a lack of proper kitchen ventilation, as well as significant dry rot, heating system problems, and concerns about carpeting affecting an asthmatic child's health.

These complaints were all marked as "Not Active," suggesting they were addressed, though no specific abatement details are provided. More recent history shows a pattern of driveway parking violations near the property, with six documented incidents of blocking driveways between 2023 and early 2025, resulting in several citations and officer responses, though some vehicles were not located when enforcement arrived.

There have also been repeated incidents of abandoned furniture and debris on the street near the property, with four such cases reported in August 2024 alone, all of which were resolved by Recology. The building was involved in a minor cooking-related fire incident (contained to a container) with no civilian injuries, though no date is specified for this event. The most recent building permit on record is from 2014 for street space usage, with a nominal cost of $1.00.
