Verdict
Full re-application
There is nothing at the state level to transfer your Idaho license into: Pennsylvania issues no statewide plumbing license, so plumbers there are licensed at the contractor level or by cities and counties. Not applicable — Pennsylvania has no state-level plumber license, so there is no statewide exam to waive or transfer; each municipality sets its own plumber licensing and exam rules (for example, Philadelphia requires passing the ICC-based Journeyman Plumber Examination on the Philadelphia Code). The move is a local or contractor-board application, not a reciprocity filing — identify the authority that governs your worksite and work from its exam, experience, and fee rules. Your Idaho license may count toward a local experience requirement, but Pennsylvania has no state credential for it to reciprocate into.
What changes, Idaho → Pennsylvania
| Idaho (current) | Pennsylvania (destination) | |
|---|---|---|
| Application fee | $51.9 ($51.90 non-refundable application/processing fee, charged at the same rate whether the application type is Initial, Reciprocal, or Reopen Closed License (DOPL Plumbing Journeyman Application, revised 2024-10-03). Not included in this amount: the IAPMO journeyman examination fee paid to PSI, later renewal fees, and the 2.5% Access Idaho surcharge added when paying by credit or debit card. idaho.gov hosts still refused direct connections on 2026-09-01, so the DOPL application form was read from an Internet Archive capture of the board's own PDF) | No statewide fee. Fees are set locally; for example, Philadelphia's journeyman plumber license is $126 initial (including a $25 non-refundable application fee) and $126 annual renewal. |
| Processing time | No board-stated processing time in weeks | No statewide process; processing time is set by each municipality. |
| Licensing authority | Idaho Division of Occupational and Professional Licenses (DOPL) — State Plumbing Board | No statewide board — plumber licensing is handled by Pennsylvania municipalities (e.g., Philadelphia Department of Licenses & Inspections; Allegheny County Health Department for the Pittsburgh area) |
The destination column is what you must satisfy — Pennsylvania sets the rules for this move.
