Which of the following exempt situations requires documentation for a builder to operate without a license?

The scenario in which a builder can operate without a license while requiring documentation specifically relates to a single project exceeding $10,000. This exemption is typically tied to certain regulations that allow builders to undertake larger projects without the need for a license, provided that they can substantiate the nature and scope of their work through proper documentation. This could include details about the project, permits, or contracts that demonstrate compliance with local laws and regulations.

While other options may suggest situations where a license could potentially be waived, they do not inherently require documentation to ensure compliance with state or municipal standards like the situation with a single project that exceeds the specified monetary threshold. In this case, documenting the work provides not only a safeguard for regulatory compliance but also serves to protect both the builder and the client engaging in a substantial financial commitment.
