Augrented Insights Report

The two-unit, two-story residential building at 434 31st Avenue in San Francisco's Central Richmond neighborhood is a historic flats and duplex structure built in 1904, currently owned by Mar Yuet & Mee Yee.

The property has undergone recent maintenance work with an active $14,000 reroofing project permitted in May 2023, which should enhance the building's weather resistance and overall structural integrity. The building has also undergone a Historic Resource Assessment (HRA), though this was processed as an informational case and is now closed.

The HRA suggests the property has some historical significance, though no specific developer or project was associated with this assessment. The building's records show regular maintenance activity, with the recent roofing work representing proactive upkeep of this century-old structure.
