Quick Answer

Plumber licensing requirements vary by state. Most states require a state-issued license — California, Florida, Georgia, North Carolina, Tennessee, Arizona, Virginia, and Washington all mandate state-level plumber licenses. Texas and New York regulate primarily at the county/city level. Application fees range from $75 (North Carolina) to $500 (Tennessee) — total initial costs including insurance and bonding typically run $1,000–$5,000. Exam requirements (California CSLB, Florida DBPR, Arizona ROC) are common in high-volume states. Select your state below for exact requirements, fees, and application steps.
