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 - 

The board's online license verification system is now available on the IDPH Regulatory Programs Public Search Portal Page.  The public search page allows you to search for both individual license holders and contractor licenses. To search by an individual name, enter the search criteria in first name and last name, and then click on "Search."  To search for a contractor license, enter the business name under the field for "Facility,"  and then click on "Search." For best results, enter the percent symbol (%) at the beginning or end of your search criteria to do a wildcard search for partial values.  For example, type J% under first name and Anders% under last name to find anyone whose first name begins with a "J" and whose last name starts with "Anders," such as Andersen or Anderson.  Click on the link for "Details" to see specific license details including trade licenses held, approval date of the license, and expiration date of the license. Be advised that the link for "File a Complaint" does not work at this time. If you want to know whether someone has ever been disciplined by the board, please visit our Discipline and Public Actions page.


New Online Database

The board has transitioned to a new online database for license and exam applications and license renewal.  If you previously had a username and password for the old database it did NOT transfer to the new system.  You will be required to create a state of Iowa A&A account.  Detailed instructions for using the new system and links to the new public portal can be found on the IDPH Regulatory Programs page

Renewal Update

Individual license renewal notices and contractor renewal notices were mailed in May 2017.  If your license expired on June 30, 2017, it is now lapsed and invalid for work unless the board office can confirm a completed renewal application is on file.  As of September 15, approximately 8,900 individuals have renewed their licenses and only about 1,050 contractors have renewed their business license.  The online renewal system is available for anyone who has not yet submitted a renewal form.  Online applications require significantly less time for processing and save a paper application processing fee.  In addition, if you apply online, the license certificate and wallet card will be sent via email electronically within 24 hours of the approval date.  It is very important that users review the instructions for creating an account and submitting applications or a renewal prior to logging on.  These instructions are available on the IDPH Regulatory Programs page where you will also find a link to the public portal.  If you need to download a paper renewal form, go to the board's Licensure - Renew a License webpage and scroll to the bottom of the page.  Be advised that paper applications can take between 6-8 weeks for processing due to the high volume.

Pending Contractor Applications

You may download a list of contractors who have a pending renewal application here.  If a paper application was received, it can take up to 6-8 weeks for entering and processing.  Approximately half of the 300 pending applications as of September 8 were submitted online and have been contacted for updated bond or insurance information and have failed to respond to requested information.  The attached list is sorted alphabetically by company name and includes a brief note on the application status.  Please contact the board office if a pending application requires expediting due to a pending permit.  View the list here.

Online Database Help

The Iowa Department of Public Health has a dedicated support team to assist users with the new online database.  Support team hours are Monday through Friday, 7:30 a.m. to 4:30 p.m.  Please be at your computer with internet and email access when calling.  If you are trying to renew your license, you should also have your continuing education course information available.

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.
