869-871 Union St

The three-story multi-family residential building at 869-871 Union Street in Russian Hill, owned by the Lew Ngan Sue Survivors Trust, was constructed in 1912 and contains two units. The property has undergone several significant improvements over the years, most notably a completed voluntary seismic strengthening project in 2018 costing $45,000, which was part of the city's earthquake safety program and executed according to engineered plans. The building's window infrastructure received attention in the mid-1980s with completed and subsequently expired permits for aluminum window installations in 1985 and 1986, respectively. Recent activity includes multiple street space permits, with the most recent issued in March 2019, and earlier permits in July 2017 and June 2006, though these permits typically relate to temporary use of public space rather than building conditions. The only documented resident concern in recent years was a noise complaint filed in July 2021, which was processed through the Noise Report Queue as an informational report and marked as closed. The building's maintenance record shows regular engagement with city permit processes, though no recent permits (within the last 5 years) indicate any major structural or systems upgrades beyond the seismic work completed in 2018.
