229-231 Mississippi St, San Francisco, CA 94107

This two-unit residential building, located at 229-231 Mississippi St in Potrero Hill, is a two-story flats and duplex structure built in 1900 and currently owned by William & Anne Trus Johnson. The building's documented history shows relatively few issues over the past several decades.

In 1997, there were two notable events: the completion of structural work to repair a deteriorating walkway and replace a structural beam, followed by a housing complaint regarding an extended exterior painting project by the elderly owners that required scaffolding for several months, along with a temporary issue of discolored drinking water. The painting-related complaint was addressed and abated by October 1997, while the structural repairs were completed under permit number 9717084.

More recently, the building's location has experienced two neighborhood-related incidents recorded through the 311 system: a documented encampment cleanup in June 2019, which was resolved when the encampment was removed, and a complaint about waste receptacles being left out continuously in October 2016, which was inspected and resolved by the Department of Public Works Operations team. Neither of these recent incidents appears to have directly involved the building or its occupants.
