The two-unit, single-story residential building at 577-579 Missouri Street in Potrero Hill, owned by the Dut S Wong Family Trust, has undergone several significant maintenance and safety-related improvements since its construction in 1960. Most notably, in 2002, the building experienced a serious safety incident involving the collapse of its rear decks and stairs, prompting emergency repairs that included both dry rot removal and the construction of new three-level decks and stairs.

More recent improvements include the installation of vinyl siding in 2011 and a sewer line replacement in 2010, both completed successfully. The property has faced some ongoing maintenance challenges in recent months, particularly concerning the sidewalk area, with multiple reports of abandoned furniture and debris between September and December 2024.

There is currently one open issue related to a sidewalk defect reported in December 2024. The building's emergency response record shows one elevator-related incident involving the removal of individuals from a stalled elevator, though no civilian injuries were reported in this situation. The property has experienced recurring issues with illegal parking in the vicinity, with three documented incidents between August and September 2024, two of which resulted in citations being issued.
