Re: Structural Question, Floor Joist Holes as someone who does do pre-purchase inspections that is somthing i would note on the report, but as others have said considering the age of the house, and that houses in the 50s often were overbuilt (lumber was cheap) i wouldnt worry, i would worry about heat from the bundled cables though. As others have said as well, plumbers tend to do worse. I saw a bathroom reno that completely sectionned a joist in 4 places. One for the tub, 1 for the sink, 1 for the shower and 1 for the john, so there were sections of joist hanging from the floor... Yes the floor was holding up the joist.
