Multiple License Discount
If you are purchasing or renewing multiple ACTIVE master, journeyperson, or contractor licenses for the same individual on the same day, you are eligible for a 30 percent discount on the licensing fees. This discount does not apply to the $25 paper application fee, late renewal fees, or contractor registration fees.
New applications from 01/01/2023 to 06/29/2023 will correlate to the 01/01/2026 to 06/29/2026 section of the chart above.
Example 1: I am renewing two active journeyperson licenses (expire 6/30/2023) on the same day for the same person. The journeyperson renewal fee is $180 x 2 for both licenses = $360. To calculate the discount, multiple this fee by 30% and subtract that amount from the combined license fee: .30 x 180 = 108.00 discount. $360 - 108 = $252 due for license fee. Add $25 for a paper application. Total amount due for online renewal = $252. Total amount due for paper application = $277.
Example 2: I am applying for two active master licenses (expire 6/30/2023) on the same day for the same person. The master license fee is $240 for each license = $480. Because I am applying for both licenses at the same time, I am entitled to a 30% discount off the license fee. $480 x .30 = $144. The online license fee due is $480 - 144 = $336. The paper application fee is $336 +25 = $361.
The discount does not apply to paper renewal fees or late fees.
If you are renewing multiple licenses online, you must start and pay for each renewal on the same day to qualify.
You must start the contractor application first if you also have an individual license. Reach the fee payment screen and do not pay yet.
Complete your individual license application and pay the license fee. Return to the contractor license application and pay the license fee.

*To see all fees associated with plumbing and mechanical licensure, see Iowa Administrative Code 641-Chapter 28.
Contractor Fees
Contractors who perform services in plumbing, HVAC, refrigeration, hydronics, or mechanical systems now have a βone-stop shopβ to apply for both the contractor license and contractor registration on a single application. Previously contractors were required to apply/renew the license with the board office every three years and also submit a separate application and fee for contractor registration to DIAL on an annual basis. Beginning with this renewal, contractor licensure and registration have been combined into a single three-year application and renewal process. This means that contractors will be required to submit a fee for a three-year contractor registration in addition to the contractor license renewal fee. On the fee chart add both the PMSB license fee and the DIAL registration fee, plus any applicable late fees or paper application fees. The registration portion of the fee is transferred electronically to DIAL.
