kp's right about calling the Inspection Department. You should have Electrical, Plumbing, as well as Building Permits.
One phone call will answer that question for you. Make it on Monday!
As far as I can tell, you have commited a major construction sin, you paid cash!
Now, the builder has no incentive to talk to you because he's been paid.
What do you have for records to show what you have paid, so you can deduct it when you go to sell this place?
I would talk to the inspectors then you will probably end up at the attorney's office. It should have done in the other order, before you built, but, here you are, and now you know.
I'm glad you came by, and I hope that we have led you in the right direction.
Post back and let us know how you make out tomorrow!
