Already hold a Plumber license and moving your license to another state? Most states offer an endorsement (sometimes called "reciprocity") route that lets you transfer an active out-of-state license without repeating training from scratch, though you may still need to pass a state-specific exam, submit fingerprints, or pay a transfer fee. A handful of occupations also participate in interstate compacts, which let a single license cover practice in every member state. The table below covers every state we've researched for Plumber.
| State | Endorsement available | Compacts | Notes |
|---|---|---|---|
| Alabama | Yes | — | No interstate compact covers plumbing. Alabama runs its own out-of-state pathway: a journeyman licensed elsewhere by exam (minimum passing score 70%), currently active and in good standing with no unresolved discipline, applies using a Request for Verification of License/Registration form; approved applicants can then sit Alabama's own Journeyman exam without re-doing the 2-year work-experience requirement. Separately, Mississippi-licensed contractors have a dedicated reciprocal pathway into Alabama's Master Plumber tier. |
| Alaska | Yes | — | No interstate compact covers plumbing. As of August 8, 2025, Alaska accepts reciprocal applications for Plumbing Journeyman certificates from any other U.S. state or jurisdiction without requiring a mutual reciprocity agreement between the two states — an applicant submits a completed application with a copy of their current out-of-state license; a reciprocal certificate is issued for a full two years and renews as a normal journey-level certificate thereafter. |
| Arizona | Yes | — | No interstate compact covers plumbing contracting. Arizona does not have blanket reciprocity with other states, but the trade exam (not the AZ-specific SRE, which can never be waived) may be waived if the Qualifying Party has been a qualifying party for a licensee in this or a comparable classification, in Arizona or another state, within the preceding 5 years. Applicants for the B-1/B-2/KB-1/KB-2 building classifications may substitute the NASCLA Commercial General Building Exam for the AZ trade exam; this NASCLA substitution path is not available for the R-37/C-37/CR-37 plumbing classifications. |
| Arkansas | Yes | — | No interstate compact covers plumbing. The State Committee of Plumbing Examiners may grant reciprocal or 'automatic' licensure to an applicant who holds a plumber's license in good standing from another U.S. jurisdiction with substantially similar plumbing laws/codes; no exam, apprenticeship, education, or training may be required as a condition of reciprocal licensure. Arkansas has published bilateral reciprocity agreements with Ohio, Texas, Louisiana, and Oklahoma specifically. |
| California | Yes | — | No interstate compact covers plumbing contracting. CSLB has formal bilateral reciprocity agreements with 5 states — Arizona, Louisiana, Mississippi, Nevada, and North Carolina — covering specified classifications where scope of practice and licensing requirements are identical or fundamentally indistinguishable. Under reciprocity, an applicant holding a current license in one of these states in a matching classification may have the C-36 trade exam waived, but CSLB retains the right to still require it, and the Law and Business exam is always still required. Reciprocity does not apply to every classification even within these 5 states. |
| Colorado | Yes | — | No interstate compact covers plumbing. Colorado offers licensure by endorsement: the out-of-state license being endorsed must be active and issued/regulated by a STATE board (not a city, county, or local municipality), and must have been earned by testing on the current or previous edition of the International Plumbing Code. The applicant must also submit a Verification of Licensure form completed by the issuing state's board. Endorsement applicants cannot verify their own experience, same as the examination pathway. |
| Connecticut | No | — | No interstate compact covers plumbing. DCP's own licensing page states plainly: 'Connecticut does not have reciprocal agreements with any other jurisdiction.' Out-of-state plumbers must apply through the same examination or equivalent-experience pathways as any other applicant; only individuals (not companies) may apply. |
| Delaware | Yes | — | No interstate compact covers plumbing. Delaware offers reciprocity to an applicant holding a current Master Plumber license from another U.S. jurisdiction with 'substantially similar' standards. Per the Board's own reciprocity table: Connecticut, Iowa, and Maryland licensees need submit no proof of experience; licensees from Alabama, Arkansas, District of Columbia, Florida, Georgia, Michigan, New Hampshire, New Jersey, North Carolina, Ohio, Rhode Island, South Carolina, Virginia, or West Virginia must submit proof of at least 7 years practicing as a Master after licensure there; any other state or U.S. territory is evaluated case-by-case from that jurisdiction's law and regulations. Pennsylvania plumbing licenses (issued locally, not by a state board) do not qualify for reciprocity — those applicants must apply by examination. |
| District of Columbia | Yes | — | No interstate compact covers plumbing. As of October 2025, DC offers reciprocity specifically to Maryland-licensed Journeyman and Master Plumbers/Gasfitters: the applicant must have received their Maryland license by examination (not waiver) and hold it current and in good standing, then submit a Maryland letter of good standing/verification with the DC application, bypassing the DC exam. Reciprocal license costs are $175 for Journeyman Plumber/Gasfitter and $185 for Master Plumber/Gasfitter, both expiring March 31, 2026 regardless of issuance date. This plumbing-specific reciprocity is separate from, and narrower than, DC's Maryland/Virginia reciprocity for electricians. |
| Florida | Yes | — | No interstate compact covers plumbing contracting. Florida's formal reciprocal licensing agreements (with Louisiana, North Carolina, and Mississippi) cover only General, Building, and Residential contractor licenses — plumbing contractors are NOT included in those agreements, per CILB's own reciprocity list. A separate 'Certification by Endorsement' path (CILB Form 10) exists for out-of-state plumbing contractors who can demonstrate their prior exam was substantially equivalent to Florida's, but DBPR describes endorsement approvals as stringent and infrequent. Holders of a NASCLA-issued exam credential (2009 forward) can also apply for reciprocity if their transcript is released to CILB, though NASCLA's accepted exams are for Division I trades (GC/BC/RC), not confirmed for plumbing specifically. |
| Georgia | No | — | No interstate compact covers plumbing. The Board's own FAQ states plainly: 'Georgia does not have reciprocity with any other states for Master or Journeyman Plumbers.' Out-of-state plumbers must apply and test through the same experience/exam pathway as any other Georgia applicant. |
| Hawaii | No | — | Hawaii has no reciprocal or endorsement agreements with other states for plumber licensure -- all applicants must meet the same 5-year/10,000-hour experience requirement and pass Hawaii's own examination. Out-of-state work experience can be counted toward the 10,000-hour requirement via the standard Experience Verification form, but it does not substitute for the Hawaii exam. No interstate compact covers plumbing. |
| Idaho | Yes | — | Idaho has a dedicated Reciprocity Pathway on the Journeyman application for Montana, Oregon, and Washington. From Montana or Oregon, the applicant needs a License Verification Form showing completion of an apprenticeship program plus 8,000 hours of work experience, active license status, and licensure by examination. From Washington, the applicant needs a License Verification Form showing either 8,000 or 16,000 hours of work experience, active license status, and licensure by examination. When reciprocating from Washington or Montana, the applicant must be a resident of the state in which they hold their license at the time of application. No interstate compact covers plumbing. |
| Illinois | Yes | — | Illinois' Application for Examination includes a dedicated out-of-state section: applicants already licensed/registered as a plumber (or apprentice plumber) elsewhere, licensed by exam, can submit that license/registration plus a letter from the out-of-state licensing entity verifying the exact licensure period, and count that experience toward Illinois' 4-year apprenticeship requirement -- but they must still sit and pass Illinois' own Plumber's License examination (this is a recognized pathway into the IL exam, not a waiver of it). IDPH also publishes a separate Reciprocity Application specifically for City of Chicago licensees. No interstate compact covers plumbing. |
| Indiana | Yes | — | An applicant holding a current out-of-state plumbing license can apply via the trade/experience route (out-of-state license documentation plus an Affidavit of Experience in the Plumbing Trade from an employer) instead of completing an Indiana-registered apprenticeship -- but must still pass the Indiana Journeyman Plumber exam administered by Prov; this is not a waiver of Indiana's own exam. No interstate compact covers plumbing. |
| Iowa | Yes | — | Iowa's only plumbing reciprocity agreement (in effect since 2016) is with South Dakota, and only for licenses issued on the basis of written examination (grandfathered/non-exam Iowa licenses do not qualify). South Dakota applicants must submit a copy of their South Dakota license plus a certificate of good standing from the South Dakota Plumbing Commission. No interstate plumbing licensure compact currently exists that Iowa participates in, so compacts is empty. |
| Kansas | No | — | No statewide reciprocity exists because there is no statewide license to reciprocate into. Any endorsement of an out-of-state or out-of-jurisdiction license is a matter for the individual city or county licensing authority. No interstate compact covers plumbing. |
| Kentucky | Yes | — | KRS 318.040(6): the Department may issue a Kentucky license to a person who holds a valid license in another state, but only if that state (a) has a statewide plumbing code, (b) has an examination at least equal to Kentucky's, and (c) agrees to reciprocate with Kentucky. This is a conditional, state-by-state reciprocity provision rather than a blanket endorsement or a named interstate compact; no interstate compact covers plumbing. |
| Louisiana | Yes | — | SPBLA states it 'only reciprocates with the State of Arkansas and Texas' for the Journeyman license. Separately, an applicant holding a valid plumbing license from any other state can use it to qualify to sit Louisiana's own Journeyman Plumber exam (submitting a copy of the out-of-state license for approval), but only licenses obtained with at least 8,000 hours of qualifying experience are approved for this pathway -- this still requires passing Louisiana's exam, unlike the direct Arkansas/Texas reciprocity. SPBLA explicitly does not reciprocate Master Plumber licenses. No interstate compact covers plumbing. |
| Maine | Yes | — | Maine has no written interstate reciprocity agreements for plumbing, but the Plumbers' Examining Board considers reciprocity case-by-case: it may grant a Maine license to an applicant currently licensed in another state whose requirements and experience standards are at least equal to Maine's, provided that state extends the same privilege to Maine license holders. Applicants must submit an application, pay fees, provide proof of experience, and include certified license verification from their home state. No interstate compact covers plumbing. |
| Maryland | Yes | — | Per the Board's own licensing FAQ, Maryland 'ONLY reciprocates with the state of Delaware, the Washington Suburban Sanitary Commission (WSSC), and Baltimore County' -- and Delaware reciprocity applies only to Master Plumber/Gas Fitter licenses, not the Journeyman tier. Individuals licensed by WSSC or Baltimore County who meet minimum qualifications may obtain a Maryland license without retaking the exam. This is a narrow, named-jurisdiction reciprocity list rather than broad endorsement; no interstate compact covers plumbing. |
| Massachusetts | Yes | — | No interstate compact covers plumbing licensure. Massachusetts has no blanket reciprocity agreements with other states; instead, under 248 CMR 11.02(7) and the Board's 'Substantially Equivalent License' policy, an out-of-state journeyman/master plumber whose license has been active at least 3 consecutive years may petition the Board to have their out-of-state education/experience deemed substantially equivalent, but unless Massachusetts has a formal reciprocity agreement with that jurisdiction (none identified), the applicant must still pass the Massachusetts exam. |
| Michigan | No | — | No interstate compact covers plumbing licensure. Michigan does not have licensing reciprocity agreements with any other state; an out-of-state licensed plumber must still take and pass the Michigan Journey Plumber exam, though notarized letters documenting prior supervised work experience can be submitted toward the 6,000-hour experience requirement. A narrow military-family exception exists: an active-duty military member, veteran, or their dependent who holds a valid out-of-state plumbing license may qualify for licensure without examination under MCL 339.6115. |
| Minnesota | Yes | — | Minnesota has reciprocal licensing agreements with some other states: an applicant who obtained an equal-or-greater class of plumbing license by examination at the state level in a reciprocal state (not via a city/local reciprocal or grandfather clause), scored at or above Minnesota's required passing score, and has held that license for at least 1 year may qualify for a Minnesota license through this reciprocal pathway. Separately, holding a current out-of-state plumber's license from a jurisdiction that itself requires at least 4 years of practical experience is one of the qualifying pathways to sit the Minnesota journeyworker exam. No interstate plumbing licensure compact exists, so 'compacts' is empty. |
| Mississippi | Yes | — | No interstate compact covers plumbing contracting. MSBOC has bilateral reciprocity agreements with several state contractor-licensing boards that waive the Mississippi Plumbing trade exam (for a $50 fee) for applicants who hold a current, qualifying out-of-state license without recent disciplinary action - Tennessee is the only listed state that waives BOTH the Mechanical and Plumbing trade exams outright; others (Alabama, Arkansas, Louisiana, Ohio, South Carolina Residential Builders Commission) waive plumbing/mechanical trade exams under specified conditions. All reciprocity applicants must still take the mandatory Law and Business Management exam and submit a full MSBOC application with all standard fees and documentation. |
| Missouri | No | — | No statewide reciprocity exists for plumbers, since there is no mandatory statewide individual license to reciprocate. RSMo §341.010 requires each qualifying city/town (15,000+ inhabitants) to run its own certification board, and a license held in one Missouri municipality (e.g. St. Louis or Kansas City) does not automatically satisfy another municipality's requirements. No multistate plumbing licensure compact exists for this occupation. |
| Montana | Yes | — | No interstate compact covers plumbing licensure. Per ARM 24.180.603 and 37-1-304, MCA, Montana has reciprocal agreements for Journeyman licensure ONLY with Oregon, Idaho, North Dakota, and South Dakota: the applicant's out-of-state license must be active and free of complaints, and a license-verification letter from the issuing state is required. If the originating state did not require a practical exam with a 70% passing score, the reciprocity applicant must still pass Montana's practical exam. Reciprocity applicants pay a $400 application fee (vs. $270 by examination). Out-of-state applicants who don't qualify for formal reciprocity, or who are from states with no journeyman/master licensing, may still receive experience credit via notarized statements, but generally must sit for Montana's exams. |
| Nebraska | No | — | No interstate compact covers plumbing licensure, and no statewide Nebraska license exists for another state's license to be reciprocal with. Any reciprocity or license-recognition policy for out-of-state plumbers would be set individually by each city's local plumbing board (e.g. Omaha, Lincoln), not by a single state authority. |
| Nevada | No | — | No interstate compact covers plumbing licensure. No reciprocity, endorsement, or out-of-state license-recognition policy was found published on NBOPE's own site (testing information, recertification information, or downloads/links pages); an out-of-state plumber appears to need to apply and sit for Nevada's own Journeyman exam like any other candidate, though out-of-state work experience can potentially be documented toward the 8,000-hour Affidavit of Experience. Applicants should contact NBOPE directly to confirm current policy. |
| New Hampshire | Yes | — | No interstate compact specifically covers plumbing licensure (New Hampshire's own reciprocity page notes it participates in 'several interstate compacts' for licensure portability generally, but none identified are plumbing-specific). Under House Bill 594 (effective August 27, 2023), OPLC must issue a license to an applicant who holds an active license in good standing from another jurisdiction whose licensing requirements are 'substantially similar' to New Hampshire's, without requiring transcripts, exam results, or experience evidence otherwise needed. Reciprocity is not available for Apprentice Plumber registrations. |
| New Jersey | Yes | — | No interstate compact covers plumbing licensure. The Board's FAQ states that 'out-of-state licensed plumbers may apply through reciprocity if their state's standards are comparable and reciprocate with New Jersey,' but this reciprocity detail is documented specifically in the context of the Master Plumber LICENSE rather than the Journeyman registration; no separate Journeyman-specific reciprocity policy was found, so this should be treated as most clearly established at the Master level. |
| New Mexico | No | — | No interstate compact covers plumbing licensure. The official CID Journeyman Certificate Application's multi-state reciprocity checkbox (which lists Alaska, Arkansas, Colorado, Idaho, Montana, Nebraska, Oklahoma, South Dakota, Texas, and Wyoming) is explicitly restricted to the Electrical Journeyman (EE98J) classification only -- it does not extend to Journeyman Plumber (JP). The main general-reciprocity path available to plumbers is the expedited pathway under 14.6.4.8(D) NMAC for military service members, their spouses/dependents, and veterans who hold a substantially equivalent out-of-state license or certification (fee-exempt for the first 3 years); outside of that military pathway, no general civilian reciprocity for JP was found, so endorsementAvailable is recorded as false. |
| New York | No | — | Not applicable — there is no statewide New York plumber license to reciprocate into or out of. No interstate compact covers plumbing licensing. |
| North Carolina | No | — | The Board's own application packet states plainly: "There is no license reciprocity. All applicants must meet the North Carolina experience requirements." The only cross-state accommodation is a technical-exam waiver for specific active South Carolina residential/commercial licenses mapping to specific NC classes (e.g. SC Residential Plumbing → NC Plumbing Class II) — waiver applicants still take the NC business-section exam and must meet NC's experience requirements. Separately, military veterans and military spouses holding a substantially equivalent out-of-state license/training may obtain an NC license without examination under G.S. 87-21(g)/93B-15.1, paying a $30 application fee plus the $150 annual license fee. No interstate compact covers plumbing contractor licensing. |
| North Dakota | Yes | — | The Board offers licensure without examination by endorsement for out-of-state journeyman/master plumbers from South Dakota (current license holders who are ND residents), Minnesota (journeyman license held at least 1 year, ND resident), and Montana (current journeyman or master license holders). All endorsement applicants must submit a Certificate of Endorsement from their licensing state, not just a copy of the license. Plumbers licensed in other states generally may also apply for an ND journeyman/master exam and license per 62-02-01-01(2) and (4). No interstate compact covers plumbing licensure. |
| Ohio | Yes | — | OCILB offers state-specific reciprocity applications rather than blanket reciprocity — confirmed forms exist for Tennessee, West Virginia, Alabama, Louisiana, and Mississippi (among others). For Tennessee, for example, the applicant must currently hold an active Tennessee license obtained by testing or grandfathering (not itself obtained via reciprocity), submit a Reciprocity Verification of Licensure completed by the issuing board, carry $500,000 liability insurance, and still pass Ohio's business-and-law exam; the reciprocity application fee is $25 per trade. No interstate compact covers plumbing/commercial-contractor licensing. |
| Oklahoma | Yes | — | Oklahoma's only confirmed formal reciprocity agreement for plumbing is with Arkansas: an applicant must have held an Arkansas unrestricted/unlimited plumbing journeyman (or higher) license for at least 1 year, obtained it by examination sponsored by Arkansas itself (not via reciprocity from a third state), be in good standing with no pending discipline, and not have performed unlicensed plumbing work in Oklahoma within the prior 2 years. The Arkansas licensing agency (Protective Health Codes) must complete and seal Part 2 of CIB's verification form; the reciprocal license fee is the same $75 ($50 license + $25 application) as a standard journeyman license. Outside the Arkansas agreement, other out-of-state license holders can only use their license as qualifying experience toward sitting the standard Oklahoma exam, not as a waiver of testing. No interstate compact covers plumbing licensure. |
| Oregon | Yes | — | BCD's official reciprocal-licenses page lists bilateral Journeyman Plumber reciprocity agreements with Idaho and Montana only (not Washington, despite some third-party sites claiming otherwise). BCD will accept a reciprocal license only from a state where the applicant actually tested (not itself obtained by reciprocity), and the out-of-state license must be current, active, equivalent or higher, and free of violations/conditions within the past 3 years; applicants use the Reciprocal Plumbing License Application. No interstate compact covers plumbing licensure. |
| Pennsylvania | No | — | Not applicable — there is no statewide Pennsylvania plumber license to reciprocate into or out of. No interstate compact covers plumbing licensing. Any reciprocity would have to be negotiated locally by an individual municipality (e.g. Philadelphia), and this research found no evidence of such an agreement on Philadelphia's official licensing pages. |
| Rhode Island | Yes | — | A plumber duly licensed by examination in another state may be issued an RI license if that state's requirements are the same as Rhode Island's for the equivalent classification, and the applicant submits a copy of their current out-of-state license, an attestation of licensure status from the issuing state's plumbing board, and an affidavit of having passed a written exam in that state for the classification sought — but the applicant must still pass a Rhode Island written exam in that classification (Section 6.0, "Out-Of-State Licensed Plumbers"); this is not a full exam waiver. No interstate compact covers plumbing licensure. |
| South Carolina | Yes | — | The Commission has an Exam Waiver Agreement (technical portion only) with North Carolina and Mississippi — an applicant licensed by examination (not grandfathered) in one of those states can skip the Residential Plumbers technical exam but must still pass South Carolina's Business Management and Law exam. Separately, holders of a SC Commercial Mechanical Contractor license with a plumbing classification, or anyone who has passed the Master Plumbing exam through the Municipal Association of South Carolina (MASC), can likewise skip the Residential Plumbers technical exam (still must pass the Business & Law exam). No interstate compact covers plumbing licensure. |
| South Dakota | Yes | — | The Commission's reciprocal-agreements page does not list specific partner states; instead it evaluates each nonresident applicant case by case. Registration without examination is available if the applicant's home state's plumbing-licensing requirements are "substantially equivalent" to South Dakota's: the applicant must have been licensed by examination (not by reciprocity) in that state, that state's licensure laws must be similar to South Dakota's, and that state's plumbing code must equal or exceed South Dakota's. Reciprocity applicants must also submit proof of license by exam, license verification, and proof of completing 4 hours of continuing education. No interstate compact covers plumbing licensure. |
| Tennessee | No | — | Tennessee's own regulatory-board page for Limited Licensed Plumbers states plainly that 'the LLP exam is not reciprocal with other states license exams' — an out-of-state plumbing license cannot be used to waive the Tennessee LLP trade exam. (Within Tennessee, a local government plumbing license/registration can be submitted in place of a fresh LLP exam score on the application.) No interstate plumbing licensure compact exists, and Tennessee is not a member of one for this occupation. Retrieved via archive snapshot 2026-02-11 of the Board's llp.html page, which has since been reorganized into the current 'How to Get a License' page structure cited elsewhere in this record. |
| Texas | Yes | — | Texas has formal reciprocal-licensing agreements with Louisiana (Louisiana journeymen who also hold an active Louisiana gasfitter license may obtain the equivalent Texas license without examination) and Arkansas (Arkansas plumbers must have held their Arkansas license for 4 years to qualify). Plumbers licensed in other states without a reciprocity agreement may still apply for a Texas license by endorsement through TSBPE by submitting an official letterhead letter from their home-state licensing authority confirming their journeyman/master license, its duration, renewability, and disciplinary history, and demonstrating that the home-state credential is substantially equivalent to the Texas one. No interstate plumbing licensure compact exists; Texas is not a member of one for this occupation. |
| Utah | Yes | — | Utah does not have blanket reciprocity agreements but does offer licensure by endorsement for certain classifications with Arizona, California, Louisiana, Nevada, and South Carolina (per DOPL's Journeyman Plumber Endorsement to Utah map) — the license must have been held in the endorsement state to count toward Utah's work-experience requirement. Eligible out-of-state applicants submit a Verification of Licensure from their home-state licensing authority; all endorsement applicants must still pass the applicable Utah law/rule exam. Applicants from states without an equivalent license must meet Utah's standard experience/exam requirements from scratch. No interstate plumbing licensure compact exists for this occupation. |
| Vermont | Yes | — | Vermont does not have formal reciprocity agreements with other states, but its 'Universal License' pathway lets a Journeyman-equivalent license holder from another state obtain a Vermont Journeyman license without retaking the Vermont exam, by submitting a certified letter of licensure from the issuing state plus proof of the apprenticeship/schooling behind that license and 8,000 hours of experience. A separate Reciprocal Military License pathway exists for veterans with qualifying training and experience. No interstate plumbing licensure compact exists for this occupation. |
| Virginia | Yes | — | DPOR's official reciprocal/examination-agreement list shows one plumbing-specific agreement: an examination-exemption agreement with the Washington Suburban Sanitary Commission (WSSC, covering Montgomery and Prince George's Counties, MD) for Journeyman and Master Plumbers and Gas Fitters — WSSC-licensed plumbers can obtain a Virginia license without retaking the Virginia exam. Separately, the standard Journeyman application lets any applicant who currently holds a journeyman or master plumber license/certification from an out-of-state regulatory body use that credential (via a Certification/Letter of Good Standing) to satisfy Virginia's experience/training requirement — but unless the WSSC exemption applies, that applicant must still pass Virginia's own PSI exam. No interstate plumbing licensure compact exists for this occupation. (Some third-party sites claim broader bilateral master-plumber reciprocity with Maryland, North Carolina, and West Virginia, but DPOR's own official reciprocal-agreements document does not list any such plumbing-specific agreements beyond WSSC, so those claims are not used here.) |
| Washington | Yes | — | Washington has a reciprocal agreement with Idaho: an active Idaho Journey Level plumber card, emailed with photo ID to L&I, qualifies for a Washington certificate without retesting. Oregon has no reciprocal agreement. Applicants with an active license from any other state, or documentation of qualifying U.S. military plumbing experience, may email their credentials to L&I for case-by-case consideration; absent an approved reciprocity/consideration route, out-of-state plumbers must pass the Washington Journey Level exam like any other applicant. No interstate plumbing licensure compact exists for this occupation. |
| West Virginia | Yes | — | 42CSR32 §14 gives the Commissioner discretion to grant a West Virginia license of the same classification, without examination, to an applicant already licensed/authorized as a master, journeyman, or plumber-in-training by another state with requirements equivalent to West Virginia's, upon satisfactory proof of qualifications and payment of the standard license fee. A separate discretionary work-experience route (§14.2) allows licensure without exam for applicants whose relevant work experience was in a state that does not license plumbers at all. No interstate plumbing licensure compact exists for this occupation. |
| Wisconsin | Yes | — | DSPS accepts a comity applicant for the Journeyman Plumber exam (not a full no-exam waiver) who: (a) completed a plumbing apprenticeship in Wisconsin or another state; (b) passed a journeyman plumber examination in another state; and (c) has practiced at least 5 years under that state's journeyman (or equivalent) license, where the department determines the other state's licensure provisions are substantially similar to Wisconsin's and the applicant has no related disciplinary history (DSPS form #3126, route C). A shorter comity route (route B) is also available for those with a 5-year, 576-hour out-of-state apprenticeship, who must still pass the Wisconsin exam. No interstate plumbing licensure compact exists for this occupation. |
| Wyoming | No | — | No statewide plumber license exists in Wyoming, so there is no state-level reciprocity or endorsement process to report. A plumber licensed in one Wyoming municipality is not automatically authorized to work in another — each jurisdiction that licenses plumbing sets its own rules for recognizing out-of-jurisdiction licenses. No interstate plumbing licensure compact exists for this occupation. |
"Endorsement available" reflects whether the destination state has a published route to transfer an active out-of-state license. Always confirm current rules with the issuing board before relying on endorsement to practice in a new state.
