Final answer:
A licensed builder should usually report minor changes in their license within 30 days, but this period may vary depending on local regulations.
Step-by-step explanation:
When a licensed builder undergoes minor changes in his/her license, such as a change of address or business name, it is typically required to report these changes to the licensing board or relevant authority within a certain timeframe. Although the specific number of days can vary by jurisdiction, a common requirement is to report the changes within 30 days. It is important for the builder to stay informed about the local laws and regulations related to licensing to ensure compliance and to prevent any issues that could arise from not reporting changes in a timely manner.
