These two Victorian houses are the last of their generation on this block. They sit hemmed-in by more recent apartment buildings.
As you can see, the one on the right is freshly painted---blue, with white trim. The pair of front doors indicates it was built with separate first- and second-floor apartments. Not all Victorians were built as grand, single-family homes. The four electric meters suggest that the ground level has been remodeled to make two studio apartments.
The house on the left could use a coat of paint. Someone painted the first story in a shade of blue that does not match its neighbor. The plywood on the front door and the drawn shades, except for the upstairs room with no shades, suggest the house sits empty.
It's not unusual to see run-down empty houses in San Francisco, despite the astronomical price of real estate. Sometimes we see one repainted and remodeled after years of neglect. Who knows why?
