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. 

For questions, please call our toll-free number at 1-866-280-1521 or by using the "Contact Us" option on this site. If you have email, please join our list serve to automatically receive updates. To join, send a blank email to: join-PMSB@lists.ia.gov.

Online License Applications & Renewal

To apply for a license online or to renew a license online, please visit the Licensed in Iowa website and click on the link for "Plumbers & Mechanical Systems Board" on the top right of that page or go directly to our online services page at https://eservices.iowa.gov/pmsb/.  Prior to logging on to apply for or renew a license, you must register and create an account by following the link on that page.  If you know your username but have forgotten your password, click on the link on that page to reset your password.  If you have forgotten both your username and password, please call our office during normal business hours to request that we reset your account.  For security reasons, be advised that only the licensee can request their username and password be reset.  We will not accept requests on behalf of employers, employees, or family members to reset a licensee's account.

Also please note that the following categories of licenses are not available for online submission: contractor license application or contractor renewal; post-examination licensure, or renewal/reinstatement of a license that is more than 60 days past expiration.  These applications can only be submitted via the paper application.  Visit our Licensure page to download any paper applications or forms.

Public Search for a License/Online License Verification

The Licensed in Iowa website includes a public search function that allows anyone to search by name, license number (listed as user # on the public search page), license type or trade.  This list is updated in real time and will show the profession/trade each person is licensed in, license status (active/expired/revoked, etc) along with the date the license was issued and date the license expires.  The list does not currently include licensed contractors.  A list of current 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.

Announcements

2015 Code Updates

The board has adopted the 2015 versions of the mechanical and plumbing code.  The new codes became effective June 1, 2016.  Please see our Iowa Code page for additional details.

Apprentice Fees

Note:  License fees are normally pro-rated based on the length of time the license is issued (all new licenses expire on June 30, 2017).  The fee for apprentice licenses issued between July 2016 and December 2016 is $16.65.  Be advised that the online apprentice application is currently charging the full $50 apprentice fee.  As an alternative, applicants may complete the online apprentice application without paying the online fee and submit a separate check to our office for the correct amount.  Include a note that the fee is for an apprentice application entered online and include your contact information.  You will not be charged the $25 paper application fee IF you enter the apprentice application online and submit payment by check or money order separately.  However, if you want to pay by credit card through the online system, you will be charged the full $50 fee. 

Mechanical Licenses

SPECIAL NOTE: A new mechanical license is available at renewal.  If you are eligible for the mechanical license, it will be the first option on your online renewal.

  • If you are also renewing a plumbing license, make sure you click the box that appears when you begin filling out the application.
  • At the end of the online mechanical application, Do Not Check Out. Select the button “Submit and Return Home” in order to add a plumbing and or specialty license and qualify for the 30% discount.
