not to side with the builder, but unless they're building the house themselves and the construction loan is in their name, the house isn't theirs until the documents are signed and the house is closed on, with the construction loan turned over into a mortgage, so without knowing the details, I wouldn't say the builder is working for them.
As alluded to,the other thing is there is most likely a schedule of when the other trades are to come in, sheetrock, etc. and the longer they're delayed, the more interest is paid on the construction loan, which may or may not be the OP's bill to pay. If this is a development or spec house, then even more so. The builder, in all rights, from the sound of the original post and comments would be within his rights to tell the OP to pound sand for running his own wiring or changing the construction timetable, as I read this to NOT be a custom home or anything out of pocket other than a deposit by the OP.
Many inspectors or insurance companies in my area will not allow the closing on the house if items are not "completed" which includes holes and wires sticking out of the sheetrock. They'll allow a blank electrical plate or prewire plugs, but a hole or wire, no go.
The one thing I'll point out is the builder is allowing all of this to happen, right or wrong, AFTER the rough inspection has been completed and signed off on, prior to buttoning up the walls, so technically, the wiring is not being inspected, looked at, or permitted, so I don't disagree with not leaving any exposed in the house....CYA if you please.
I can't recall the original thread, but I haven't met too many builders that won't allow a person to bring in their own licensed and insured people, along with a signed permit on the job during the construction phase, unless the house is not under contract and sold or the house is a spec house.
Just pointing out both sides of the fence, because of how I read Ranger's posts, I, as a builder, would take a hard line if the "you work for me, I pay your check" rant started coming out and I would tell him that if he wanted to play by the rules, permits, inspections, etc. then I'd think about it, otherwise he can do as he wants once the house is in his name. Unfortunately, for me, I've seen far too many results of "prewires" done by those that knew enough to be dangerous or had the idea, just poorly planned and executed.
