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.
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.
As of November 2017, approximately 9,800 individuals have renewed one or more personal licenses and approximately 1,400 contractors renewed their business license. If your license expired on June 30, 2017, it is now lapsed and invalid for work.
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 up to 4 weeks for processing.
If you contract for plumbing, mechanical, HVAC, refrigeration, sheet metal or hydronics services in the state of Iowa your business must have a contractor license and contractor registration from the Division of Labor. Please note that the business license is separate from the master license! Simply renewing your master license is not sufficient.
You must also submit a separate renewal form and fees for the contractor license. The application and fees also include a 3-year renewal fee for contractor registration through the Division of Labor at Iowa Workforce Development. Once an application is submitted to the board office, a portion of the fees paid and data are sent to the Division of Labor electronically. The Division of Labor will review and issue a new contractor registration number and send a new contractor registration card directly to you. Once the new registration number is issued, board staff review the application to determine if the license can be issued. If all requirements are met (master license has been renewed or issued, bond and insurance on file), then the contractor license is issued. Keep in mind that BOTH are required in Iowa. If you have not received BOTH a new registration card from the Division of Labor AND a license certificate for the BUSINESS from the board office, you have not completed the requirements.
Links to the online application and forms to obtain a new license and registration or renew an existing license or registration are available on our website here: https://idph.iowa.gov/pmsb/licensure/contractor. Bond and insurance requirementsm are also detailed on that page.
