FAQ

Which states have the toughest plumber licensing?

Measured by published hours, the strict ladder states cluster around 8,000 supervised hours for journeyman level (Texas, Washington, Michigan, Colorado for electricians). Contractor-only states look "easier" on paper but require 3–5 documented years to contract legally.

Which states don't license plumbers at all?

It varies by trade — see the "local rules" rows in the table. Pennsylvania licenses none of the three trades statewide; Illinois licenses plumbers but not electricians; New York leaves all of it to cities.
