Looking to hire a contractor can be a daughting task–I know. I work with the companies and had to find these resources myself. A big part of that task is finding the information you need to know. (Please do NOT assume you know, that is how people get into trouble.) A step-by-step process is available in my book, Hiring a Contractor which is available on Amazon. Links to finding your local information are listed here. The information is listed by state, click on the link that corresponds to your state.

Good luck and feel free to contact me if you have any questions.

If you find other information that needs to be included / updated please contact Mel DePaoli at mel [at] omicle.com. Thanks for your help and good luck!
