Background: commercial and residential construction including many home reconstructions. Technically I've not self built, but completed major Reno's and extensions (less paperwork!).
BC is abysmal with its outdated and inflexible codes. Instead of supporting people to do better (homeowners especially) it hides behind walls of red tape that just exasperate the problems. Technical Safety BC is itself a black hole, and won't even respond to emails notifying it if breaches.
The CHMC framing book is excellent, and should be read many times before, during and after. The BC Hydro grants page also has a guide to proper insulation details (surprisingly nuanced). You will also need to complete a pretty technical forum for you homeowners electrical permit. Code changed recently so make sure your books are very recent. A great way to learn is watch progress at local sites and use the books to answer questions.
The best advice I can give is to be open with your inspectors. They are there to keep you safe, and will sometimes even positively advise you. Photograph everything (literally). You will be amazed how often you need to know exactly where wires, pipes and framing runs and this can save so much drywalling... Also helps if inspector has a concern.
Sorry, that was a bit waffle and off track. I'm in East Kootenay if your local. Best of luck, will be well worthwhile in the end.
