1151 Wisconsin St, San Francisco, CA 94107

The two-unit residential building at 1151 Wisconsin Street in Potrero Hill is a two-story flats and duplex structure built in 1900, currently owned by Stts Apartments LLC. The property's most significant historical modification occurred in 2000 with the completion of a rear two-story addition valued at $90,000, which was intended to accommodate both a three-bedroom unit and a five-bedroom unit.

This expansion was preceded by two aluminum window installation projects in the mid-1980s, specifically in 1985 and 1986. The building's recent service call history from 2022 to 2024 shows a pattern of street maintenance issues in the surrounding area, with multiple reports of general cleaning needs, including garbage, debris, and waste removal, particularly in March 2022 when four incidents of loose garbage were reported and resolved.

More recent incidents include reports of a fallen tree in March 2023, and various waste-related issues in 2024, including incidents involving human waste and an abandoned vehicle. While these external maintenance issues may affect the surrounding environment, they pertain to street conditions rather than direct building safety concerns. The property has undergone thorough regulatory review processes, including two discretionary review applications for the rear expansion project, though these were ultimately closed, with one being withdrawn.
