Permits ensure that a certified inspector inspects the construction project or installation. Inspections help make sure work is done safely and to code. When a city or county inspector approves work, you can ask questions from an expert and know that the work has been checked for safety violations. This is of particular value to the do-it-yourselfer who doesn’t make installations every day. Incorrect installations can result in house fires, flood damage, and/or structural problems. Permits help ensure that licensed contractors do the work if the homeowner doesn’t handle the job. Only Construction Contractors Board (CCB) licensed contractors, and those who carry a trade license, such as plumbers and electricians, are allowed to legally work in Oregon. State and local building departments issue permits only to contractors who are properly licensed and bonded.
