Arkansas Code § 17-38-301 in Plain English

You cannot legally do regulated plumbing work in Arkansas as a master plumber, journeyman plumber, apprentice, or restricted-license holder unless you are properly licensed or registered by the Arkansas Department of Health.

Key points:

  1. A license is required to work as a plumber.
  2. Only a licensed Master Plumber may use that title.
  3. A licensed Master Plumber (or restricted licensed plumber) must be in charge of installations in cities, towns, and utility districts.
  4. Licenses cannot be shared, transferred, or “rented.” Using someone else’s license is illegal.
  5. Plumbing inspectors also need special certification from the Department of Health.

Bottom line for homeowners:

If someone is doing plumbing work that requires a permit on your property, a properly licensed plumber must be responsible for the job.
