Specialty Trade Licensing Notes

HVAC Licensing

Most states require HVAC contractors to hold a separate specialty license beyond any general contractor license. Additionally, all HVAC technicians who handle refrigerants must hold an EPA Section 608 certification (federal requirement). Some states also require journeyman/master HVAC certifications with 2–5 years of documented experience.

Plumbing Licensing

All 50 states require plumbing licenses at either the state or local level — no exceptions. Most follow a tiered system: apprentice → journeyman (2–4 years) → master plumber (additional 1–3 years). Expect written exams at each level.

Electrical Licensing

Like plumbing, every state requires electrical licensing. The typical path: apprentice (4 years / 8,000 hours) → journeyman electrician → master electrician. Many states accept or require ICC or PSI exams. Some states have reciprocity through NASCLA.
