I have to hand it to our industry,we continually educate ourselves thru code reviews etc,which generate quite a bit of money for the providers of the reviews and also the states that we pay our license fees to.I have asked many inspectors how can other tradesman or even better how they can do there work without being licensed,have it inspected,etc.I feel every trade/person on construction site should have a license to do what they do,and have to work within specific codes and pay fees like me and you.ex:take refrigeration contractors,do they have appr./license ratios they follow?they dont even pull permits,its just very frustrating @ times on job sites where we constantly play by the rules and other trades just do there work and go about there business-....venting....
