Iowa Plumbing & Mechanical Systems Board

About the Board

The Iowa Plumbing and Mechanical Systems Board was established to administer and enforce the provisions of Iowa law regarding the licensing and regulation of plumbers, mechanical professionals, and contractors. The board issues trade licenses to plumbers, HVAC-refrigeration, sheet metal, hydronic and mechanical professionals, specialty licenses, contractor licenses, and medical gas piping installation certification. Anyone working in these disciplines in the state of Iowa is required to be licensed with the board.  The board also investigates complaints filed against licensees and investigates complaints alleging someone is practicing one of these trades without a license.

Public Search for a License/Online License Verification - Database Offline

The board's online license verification system is currently offline & will be unavailable until sometime in April 2017.  A list of currently licensed contractors is available in PDF format for download here.  If you want to know whether someone has ever been disciplined by the board, please visit our "Discipline" tab on the left side of the PMSB webpage.

Online Database Not Available

At Noon on Monday, March 27 the existing online database for the Plumbing and Mechanical Systems Board will be shut down to begin the transition to our new database AMANDA. It is anticipated that office staff will begin using the new AMANDA the following week (early April).

During this transition we will be unable to accept, issue, or approve any new online applications for licenses, exams, etc., and office staff will have  limited access to any account information. To minimize the impact on our licensees, Board staff have worked diligently to ensure that all complete applications that were received by Friday, March 24 were processed prior to the database shut down.

Database Update

The Plumbing and Mechanical Systems Board licensing database upgrade is ongoing. Our IT team was able to successfully migrate most of the data from our old system into the new database.  Work continues to test and verify the migrated data, clean up duplicate accounts, set up the public access components of the system, etc.  Beginning Friday, we anticipate that PMSB staff will have access to license and account information to be able to answer specific license questions or verify licensure status.  However, public access will not be available yet at this time.  We anticipate public access will be provided by the end of the month.  We will keep our website updated with the latest information and also send out messages to our List Serve.

As we continue in the transition, anyone who needs to apply for a new license or exam, renew a license that expires prior to April 15, or reinstate a lapsed license should submit a paper application.  All paper application fees will be waived until our new licensing database is online.  Always download and print the latest paper application form directly from the board website to ensure you are using the latest version (all forms underwent significant revision last year).  Visit http://idph.iowa.gov/pmsb/licensure and click on the appropriate license type to download license application forms.  Visit http://idph.iowa.gov/pmsb/examination to download and print the exam candidate application form.

Keep watching this page for the most recent information on this transition.

New Application Forms

The application forms for licensure, renewal, and examination have recently been revised.  To expedite processing of all paper applications, please destroy old copies of any application forms you may have on file.  Always download and use the most recent version of the forms directly from the board website.
