320-322 Missouri St, San Francisco, CA 94107

The two-unit residential building at 320-322 Missouri Street in Potrero Hill is a 2-story flats and duplex structure built in 1906, currently owned by David A Page & Melinda J Bl. The property has undergone several significant renovations since 2013, including major foundation work, kitchen and bathroom remodels, and the installation of new electrical systems.

Between 2013 and 2015, improvements were made to both units, featuring kitchen upgrades, bathroom renovations, and the installation of solar panels. The building received a substantial electrical system upgrade in 2013, including new 200-amp service panels, multiple circuits, and modern appliances. More recently, in 2022, a 240v 50amp circuit with receptacle outlet was installed.

The property has experienced some maintenance concerns regarding exterior elements, particularly sidewalks, with multiple reports of defects between 2018 and 2022, including collapsed sidewalks and tree root damage. Historical records show some permit violations from 2000 related to unpermitted work on windows, sewer lines, and sidewalk repairs, though these were ultimately abated in 2012. The building's systems have generally been well-maintained, with records showing proper permitting for most major upgrades, though there are two recently expired permits for plumbing work from 2013 and 2015 that may require follow-up for current status verification.
