Operating as a plumbing company in Aurora, Colorado without a valid state license is a violation of Colorado Revised Statutes § 12-10-234, which imposes both civil and criminal penalties. Performing plumbing work without a license is a Class 3 misdemeanor, punishable by fines of up to $500 and potential jail time up to six months. Each day of unlicensed operation constitutes a separate violation, meaning a month of unlicensed work could result in fines exceeding $15,000.

The Colorado Division of Professions and Occupations can issue Cease and Desist Orders prohibiting unlicensed individuals from performing any plumbing work in the state. Violations are discovered through citizen complaints, insurance claims investigations, and routine city permit audits.
