What is the consequence of a contractor allowing their license to expire?

A contractor allowing their license to expire must cease all work until the license is renewed because operating without a valid license is against regulatory requirements. This cessation is necessary to ensure compliance with state laws governing construction licensing, which are in place to protect public safety and ensure that contractors meet certain standards of professionalism and competency. Continuing work without a valid license could lead to penalties, legal issues, and damage to the contractor's reputation.

In this context, the other choices do not align with the legal requirements governing licensed contractors. Allowing work to continue without a license creates risks and potential liabilities that the contractor cannot legally navigate. Thus, it is crucial for contractors to be diligent about renewing their licenses on time to avoid any interruptions in work and the associated consequences.
