123 Henry St, San Francisco, CA 94114

The two-unit residential building at 123 Henry Street in the Duboce Triangle, owned by Dea Harmon, is a two-story flats and duplex structure built in 1925. The most recent significant concern involves potential safety hazards from loose roof shingles, reported to the Building Inspection Division in August 2023, though this issue was marked as abated within nine days of reporting.

The building has experienced recurring sewer-related problems, with four documented incidents between 2020 and 2022 involving 4-inch vent sewage backups, suggesting potential infrastructure challenges in this area. While not directly related to the building's condition, there have been several neighborhood maintenance issues recorded through 311 calls, including street cleaning concerns (both mechanical sweeping missed routes and loose garbage), human or animal waste on public property, and graffiti on a sign between 2018 and 2021.

The building's documented issues have primarily revolved around plumbing infrastructure and external environmental factors rather than structural integrity or safety concerns, with the most pressing recent issue being the roof shingle safety concern. The property has not had any major structural violations or safety infractions recorded in the provided history, and most issues have been addressed within reasonable timeframes according to available data.
