Verdict
Full re-application
There is nothing at the state level to transfer your Washington 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 Washington license may count toward a local experience requirement, but Pennsylvania has no state credential for it to reciprocate into.
What changes, Washington → Pennsylvania
| Washington (current) | Pennsylvania (destination) | |
|---|---|---|
| Application fee | $242.7 (Idaho reciprocal journey level applicants pay the $242.70 journey level certification fee (exam waived). Non-reciprocal out-of-state applicants pay a $202.10 examination application fee (plus a PSI scheduling fee) and then the $242.70 certification fee; a one-time 120-day temporary work permit is $100.30) | 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 | L&I does not publish a fixed processing time; out-of-state credentials are reviewed before the applicant may test or receive a reciprocal certificate, and approved applications are valid for one year | No statewide process; processing time is set by each municipality. |
| Licensing authority | Washington State Department of Labor & Industries (L&I) — Plumber Certification Program | 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.
