Augrented Insights Report

The two-unit, two-story multi-family residential building at 23-25 Castle Street in Telegraph Hill, owned by Benny Wing Lau, was constructed in 1909 and is classified as a Flats & Duplex structure.

The building's documented history over the past decade shows some recurring issues with street cleanliness and maintenance in the immediate vicinity. Most notably, there have been two recent incidents in 2024 involving garbage and debris on or near the property, with the most recent occurring in November 2024, though both cases were resolved without requiring additional work.

Approximately ten years earlier, in April 2014, there was a report of a ground sign requiring repair, but the Department of Public Transportation's Sign Shop was unable to locate the issue for resolution. While the most recent concerns relate primarily to street cleaning matters rather than building-specific issues, the pattern of street maintenance calls suggests periodic challenges with garbage and debris in the immediate area.
