Augrented Insights Report

The 4-unit, 2-story multi-family residential building at 405 Union Street in Telegraph Hill was constructed in 1958 and is currently owned by Choi Summco Kin. The property has undergone several routine inspections over the years, with the most significant safety concerns arising in 2011 when violations were documented regarding non-working fire escape drop ladders, which were classified as a life safety hazard. These violations required the property manager or owner's agent to provide proof of the ladders' functionality and ensure that all windows and doors leading to emergency fire escapes were operational and unobstructed.

Similar fire safety issues were noted in a 2005 inspection, along with concerns regarding smoke detectors and emergency exits inside the units. A blocked exits complaint was recorded in 2008, though this was subsequently corrected in early 2009. The building's permit history shows three identical permits issued on November 15, 1982, though no specific details about these permits are provided in the available data.

Recent activity around the property has primarily consisted of municipal services handling street cleaning and maintenance issues, with multiple reports in 2024 regarding garbage, debris, and catch basin maintenance. Two recent lighting concerns were reported in June 2024, but these were related to a PG&E light pole and subsequently cancelled. It's worth noting that there have been two fire-related incidents recorded, though neither resulted in civilian injuries or indicated any significant safety concerns.
