314-316 Missouri St, San Francisco, CA 94107

The two-unit residential building at 314-316 Missouri Street in Potrero Hill, owned by Eleanor Lorraine Thompson, is a 2-story flats and duplex structure built in 1906. The property has undergone several significant improvements and maintenance work over the past two decades, with the most recent major work including a house trap installation (2022) and sewer repair/replacement (2012). In 2013, substantial roofing work was completed, including shingle replacement and perimeter repairs totaling over $8,000.

Earlier maintenance included window replacements due to deterioration (2007), dry rot repairs (2006), and additional rear deck bracing (2000). The building's maintenance history shows attention to structural elements, with a 2004 electrical upgrade completing a 200-amp underground conversion. While there were some violations and complaints in the early 2000s regarding unpermitted work on the deck, facade, sewer line, sidewalk, and windows, these issues were all resolved by 2001.

More recent concerns have primarily involved external infrastructure, including sidewalk maintenance (2024), tree root impact (2024), and multiple parking enforcement calls (2023). The property has experienced five Shared Spaces-related issues, with the most recent being a resolved fire hydrant concern in September 2023. A carbon monoxide detector malfunction was recorded but resulted in no injuries. The building appears to be actively maintained, with most recent issues being primarily related to external systems and infrastructure rather than building structure or systems themselves.
