Augrented Insights Report

The two-unit residential building at 547-549 12th Avenue in San Francisco's Inner Richmond neighborhood is a two-story flats and duplex structure built in 1915, currently owned by the Young B&lai K Louie 1999 Re trust. The property underwent a significant vertical and horizontal extension in 1986, expanding its apartment capacities.

Recent months have seen multiple issues with tree maintenance, including reports of property damage in January 2025 and concerns about tree contact with the building in October 2024. There have also been recurring problems with driveway blocking, with at least four documented citations issued between September and October 2024.

Other municipal service calls include street lighting maintenance (a hanging glass cover in January 2025) and a sidewalk obstruction involving a portable toilet in September 2024, which required enforcement action and the issuance of a notice. The building's only recorded fire incident was a false alarm due to malfunction, with no civilian injuries reported.
