License Reciprocity in Iowa

South Dakota is the only state with which Iowa has a reciprocity agreement for plumbers. In May 2016, the Executive Board authorized the first reciprocal agreement with the South Dakota State Plumbing Council. The deal permits those who earned their license through a knowledge examination to transfer to another state and get similar support without practicing regularly. This implies that if you reached your South Dakota plumbing license through a knowledge examination, you might request reciprocity to receive an Iowa plumbing license without retaking the assessment and vice versa. You must also agree to follow all other Iowa rules and regulations.

The bilateral agreement covers only the journeyperson and master plumbing license criteria.

License Renewal/Continuing Education

Every licensed or controlled trade in Iowa is required by law to receive continuing education as a condition of license renewal. The basic standard for each three-year licensing term for each piping and mechanic systems regulatory license is at least 8 hours of academic learning. Extra hours are necessary for people who have multiple licenses. The committee must pre-approve both the teacher and the program to be legitimate. The council lists some, but not all, of the permitted courses on its web page. Other programs may be offered in your region through your nearest local college, labor union, or organization, as not all teachers want to publish their courses.

Insurance for Plumber in Iowa

As a plumbing professional, you must have enough general liability coverage to help yourself if you cause damage or injury while doing your service. Your insurance should protect any subcontractors you engage if they operate under your direction if you have the correct coverage in place.

Final Verdict

Plumbing license requirements vary from place to place and, in certain situations, from municipality to municipality. Starting at the trainee level, Iowa has stringent statewide rules for operating in the pipeline industry.
