Augrented Insights Report

The two-unit residential building at 531 Delta Street in San Francisco's Visitacion Valley neighborhood is a two-story flats and duplex structure built in 1945, currently owned by Oscar E and Dora L Santos.

The property's documented history shows minimal activity, with the most significant recorded maintenance occurring in March 2017 when the owners undertook repairs to the sectional roll-up garage door at a cost of $1,760. This maintenance work, which carried no structural implications for the building, was properly permitted and subsequently closed in the city's planning records.

Beyond this single maintenance record, there are no other building permits or planning actions on file, suggesting relatively limited recent modifications to this multi-family residence. The property's age and documented history indicate standard residential maintenance compliance, though the record shows no recent concerns regarding resident experience or safety within the documented time frame.
