Renewal fees are $100-$150 depending on license type. Texas requires all plumbers to complete 4 continuing education hours every two years, with at least 1 hour focused on code updates and 1 hour on professional standards (Texas Administrative Code § 301.1). Approved CE providers include the Texas Association of Plumbing Inspectors, National Association of Plumbing-Heating-Cooling Contractors (NAPHCC), and other state-approved organizations. If you miss the renewal deadline, your license becomes inactive. You cannot legally perform plumbing work with an inactive license, and you face penalties of $100-$200 per violation plus potential cease-and-desist orders. To reactivate an expired license, submit a reinstatement application with late fees ($50-$100) and proof of completed continuing education. Reinstatement typically takes 1-2 weeks.

Operating a plumbing business in Plano without proper state and local licenses constitutes a violation under Texas Water Code § 49.452 and Plano Municipal Code § 25-69.1. Penalties for unlicensed plumbing work include fines ranging from $500-$2,000 per violation or per day of continued violation. The City of Plano can issue fines of $100-$500 per day for operating without a City Plumbing License.

Criminal penalties apply for egregious violations: operating as an unlicensed master plumber is a Class B misdemeanor, punishable by up to 180 days in jail and/or fines up to $2,000. Operating as an unlicensed journeyman or apprentice is a Class C misdemeanor with fines up to $500. The State Board of Plumbing Examiners can issue cease-and-desist orders to unlicensed operators, prohibiting any further plumbing work.

Violations are discovered through customer complaints, routine city inspections, failed permit inspections, or during background checks for permit applications. Operating without a license voids liability insurance coverage, meaning you bear 100% financial responsibility for property damage, injuries, or code violations. Clients can sue for damages if unlicensed work causes harm. Unpermitted work discovered during home sales inspections can result in costly corrections or loss of sale. Repeated violations can result in criminal charges, substantial fines ($1,000-$5,000 total), and prohibition from obtaining a plumbing license for several years under Texas Water Code § 49.452(d).
