Book updated Feb 2021. In Alabama, a general contractor who works on a commercial or industrial project that costs $50000 or more must get a license. For a residential project the limit is $10000. It is the State Licensing Board for General Contractors that administers licensing.There is a MUST-TAKE Business and Law exam which covers a wide range of fundamental topics. There is no way you can pass the exam without having solid real world experience. Our notes give you knowledge, principles and concepts. To master the topics, you must be "in the field" - you need to go through the real world plans, the various contract documents and the various administrative paperworks all by yourself. And you need to know how the experts get things done. To succeed in the exam, you also need to read as many reference books as possible. There is no single book that can cover everything!
