Oregon License Information

Business and Law

Contractors wanting to work in Oregon must learn about the construction laws and business practices that affect them. It is imperative for contractors to understand how to prevent disputes by using good business practices and complying with the law. Statistics indicate the impact of the Business and Law course and test; licensed contractors who have taken the course and passed the test have had fewer claims filed against them and file fewer bankruptcies than licensees who have not taken the course and passed the test.

All new contractors must take and pass this test, as well as contractors whose license have lapsed more than 24 months, regardless of the reason.

The Oregon CCB Test is from the latest CCB Manual, which is the 9th Edition. The testing after Jan.31, 2010 will be from the 9th Edition.
