Augrented Insights Report

The two-unit residential building at 247 San Carlos Street, owned by Hai Yang Wu & Sally Xiao Yi, is a two-story flats and duplex structure built in 1906 in the Inner Mission neighborhood.

The building's permit history shows minimal activity, with only two recorded permits: a completed gas houseline extension in 2008 and a street space permit issued in 2018 with a nominal cost of $1.00. The property has generated multiple 311 calls over the past few years, primarily related to street and sidewalk cleaning issues.

Between 2021 and 2024, there have been ten reports of loose garbage or debris needing cleanup, with the most recent incident reported in September 2024. While most cases were resolved, three in early 2022 were marked as "nothing found." Additionally, there is a closed planning record indicating a previous short-term vacation rental situation that was abated, suggesting the unit was temporarily listed on a platform like Airbnb at some point.
