I was a data cabler at the start of my career.
Residential is the worst. Dwangs in walls. Cable runs are always a bitch. And even if you have a drop its not guaranteed to fit or feed another cable, and usually not easily. Many walls will have to be surface mounted blocks with capping. House ceilings suck.
Most offices have suspended ceilings , hollow walls / partitions . Built in cable ducts and catenarys. etc etc
I did exactly 4 residential jobs. Lol.
And dozens and dozens of commercial buildings.
Not in the US but this seems high-ish. But I know lots of people would feel this sort of job is seldom worth the petrol or stress.
the pay was pretty good for most work back then. But the residential stuff almost always worked out less /hr (more effort) so we almost never did it. So infrequently I can remember every job. Or maybe just all the swearing etc burned them into my memory ? 🤣
