I am in the process of getting into building inspection and I am studying to take the ICC exams. I worked for a drywall company, so I did ceilings, drywall of course, and metal stud framing. Is there a good website or something so I can learn the other trades better. I.E mechanical, electrical and plumbing. Any help or advice would be greatly appreciated.

Have you checked out Welcome to the International Code Council (ICC): Your source for building safety products and services and the International Codes They offer online courses in all of the different areas. Click on the Training link on the home page and check out the ICC Campus Online.

So are you telling us you want to test out to become a home inspector without taking formal training for the trade, just testing out?
