Maryland requires a state journeyman plumber license for most plumbing work. The typical path starts with a 4-5 year apprenticeship program totaling 8,000-10,000 hours of on-the-job training combined with classroom instruction. United Association (UA) Local unions offer structured apprenticeships with guaranteed wage progression, starting around 40% of journeyman wages and increasing every six months. Non-union apprenticeships are also available through contractor associations and community colleges. During apprenticeship, you'll earn while you learn, starting around $17-20 per hour and reaching near-journeyman wages by completion. After finishing your apprenticeship, you must pass the Maryland state licensing exam to become a licensed journeyman plumber. The exam covers state codes, safety regulations, and technical knowledge. Some counties and municipalities may have additional licensing requirements. Maryland also offers specialized endorsements for gas fitting and backflow prevention. Community College of Baltimore County and other institutions offer pre-apprenticeship programs that can give you an advantage when applying to competitive apprenticeship programs. With approximately 380 programs available nationally, opportunities exist throughout the state.
