Which of the following is required for a business to obtain a contractor's license?

For a business to obtain a contractor's license in Arizona, providing proof of insurance is essential. This requirement is in place to ensure that contractors are financially capable of covering potential liabilities associated with their work. The Arizona Registrar of Contractors mandates that licensed contractors maintain a certain level of insurance to protect clients and the public from risks like property damage or injuries that may occur during construction activities. By having appropriate insurance coverage, contractors can demonstrate their professionalism and commitment to responsible business practices, which is crucial in the construction industry.

While aspects such as having a physical office location, a registered trade name, or submitting a business plan can be important for operating a business in general, they do not specifically fulfill the licensing requirements set by the Arizona Registrar of Contractors. Understanding the critical role of insurance helps illustrate why it is a requirement for obtaining a contractor's license.
