This is a bank of three houses at the corner of NE Couch and 8th. They’re surrounded by a bunch of industrial buildings and I’m surprised they have survived this long.
However, they do not have much in the way of backyards. Instead, their former backyards are now a parking lot for the apartment building behind them.
The most awesome Portland Maps site tells me that all three houses are owned by Volunteers of America. One was bought in 1989 for $63,000, another in 2001 for $450,000. There’s no data on the sale of the third one.
I would assume that these are either used as halfway houses, or other things for VOA’s many programs, so perhaps not entirely residential, but yet more commercial among the commercial.
