What is the penalty for practicing the occupation without a license?

Practicing the occupation without a license carries significant legal repercussions, which is accurately captured in the first option. Engaging in unlicensed activity undermines industry regulations intended to ensure public safety and maintain professional standards. As such, the penalties are established to both deter unlicensed practice and emphasize the importance of compliance with licensing laws.

The specified range of fines, from a minimum of $5,000 to a maximum of $25,000, along with the potential for jail time of up to one year, reflects the serious nature of the violation. These harsh penalties serve as a reminder of the legal and ethical responsibilities that come with being a licensed professional in the residential building sector. Additionally, the inclusion of both financial penalties and potential incarceration underscores the seriousness of the offense, reinforcing the importance of operating within the bounds of the law.

Other options do not match the severity typically associated with practicing without a license. A lower fine or temporary suspension fails to adequately convey the gravity of the offense, while a warning and mandatory training suggest a more lenient approach that might not effectively deter future violations. The stringent penalties outlined in the correct answer are intended to protect consumers and maintain trust in the industry.
