Connecticut requires plumbing contractors to hold a state license through the Department of Consumer Protection. For residential work up to 4 units, you need a Residential Plumbing Contractor license (P-2). For unlimited commercial and residential work, you need a Plumbing Contractor license (P-1). Both require passing a written examination covering Connecticut Plumbing Code, business law, and safety practices. Applicants must have 4 years of plumbing experience or equivalent education. New Haven does not require additional local licensing beyond the state license. License renewal is required every 2 years with continuing education requirements of 8 hours for P-1 and 4 hours for P-2 licenses.
