Just curious...
Calgary28, just curious, but do you happen to be in Calgary?
If you are, I would be interested to know who your builder is ( was? ). As you can see I am from Calgary and had my home built 11 years ago. At the time I had some additional wiring done ( anything was possible for a price ) but I chose to do some rough-in stuff myself.
My builder, one of the biggest in the city, wasn't keen on the idea but I pointed out that I was the one paying for the house and that all the materials and labour would meet or exceed code. You
MUST do any wiring before the rough-in electrical inspection.
The actual sales contract didn't say I could do this stuff myself but it didn't specify I couldn't either. I just "leaned" on the builder pretty hard. Basically I told them I would not be willing to let anything slide on their part if they didn't co-operate. If they wanted to be difficult I would hold them to the letter of the contract and absolutely everything in the blue prints.
Most builders are the same, there are always some things that get done wrong and it costs them money to fix it. That's where you get "room to negotiate"....
