1200 Mariposa St, San Francisco, CA 94107

The property at 1200 Mariposa Street in Potrero Hill is a two-story, multi-family residential building constructed in 1907, containing three units and currently owned by Twin Tigers Living Trust. The building's history reveals several notable events, most significantly a 2015 attempted permit to remove an illegal dwelling unit and associated plumbing fixtures, though this permit was ultimately cancelled. A sewer repair was completed in 2008, representing the only other permitted work on record.

Recent municipal service calls between 2021 and 2025 suggest ongoing maintenance and cleanliness challenges in the immediate vicinity of the building. These issues include multiple incidents requiring general street cleaning, graffiti removal, and various sign repairs throughout 2021-2022. More recent concerns include reports of abandoned vehicles (June 2024), waste (September 2023), and general service requests (May 2024).

While these external issues don't necessarily reflect on the building's internal condition, they do indicate some level of maintenance required in the surrounding area. The building's most significant historical modification occurred with the ground floor unit's removal, which was conducted without proper permits and subsequently addressed through official channels, though it appears this unit was not subject to the usual post-construction requirements. This removal process, initiated in 2015, seems to have been part of the broader effort to regularize the building's unit configuration.
