Pennsylvania does not license plumbers at the state level.
Pennsylvania does not license plumbers. There is no statewide plumber licence, no state plumbing board, no state plumbing examination and no state fee schedule - and the negative has to be proved against the agency that would hold such a board. The Department of State’s Bureau of Professional and Occupational Affairs “provides administrative and legal support to 29 professional and occupational licensing boards and commissions” and names every one of them: Accountancy, Architects, Auctioneer Examiners, Barber Examiners, Certified Real Estate Appraisers, Chiropractic, Cosmetology, Crane Operators, Dentistry, Engineers/Land Surveyors/Geologists, Funeral Directors, Landscape Architects, Massage Therapy, Medicine, the Navigation Commission, Nursing, Nursing Home Administrators, Occupational Therapy, Optometry, Osteopathic Medicine, Pharmacy, Physical Therapy, Podiatry, Psychology, the Real Estate Commission, Social Workers/Marriage & Family Therapists/Professional Counselors, Speech-Language Pathology and Audiology, Vehicle Manufacturers/Dealers/Salespersons, and Veterinary Medicine. Plumbing is not there, and neither is any other building trade.
The positive proof runs through a statute that assumes plumber licensing happens locally. The Home Improvement Consumer Protection Act (Act 132 of 2008, effective July 1, 2009) preempted local registration of home improvement contractors, and then wrote in an exception for exactly this situation: sec. 12 provides that “[t]his provision does not affect existing licensing standards in effect on the effective date of this act, with respect to electricians and plumbers and other trades, where licensing is conditioned on requirements of testing or possession of certificates obtained through specific training in electricity or plumbing or other trades.” The Attorney General’s FAQ repeats it in plain English: political subdivisions cannot separately license or register home improvement contractors after July 1, 2009, “with the limited exception of licensing standards that are in effect on July 1, 2009, with respect to electricians, plumbers and other trades where licensing is conditioned on requirements of testing or possession of certificates obtained through specific training in electricity, plumbing or other trades.” A legislature does not write that sentence unless plumber licensing lives in the cities and counties.
And it does - held by the INDIVIDUAL WORKER, which is what makes Pennsylvania different from most local-licensing states. In PHILADELPHIA, Philadelphia Code sec. 9-1003(2)(a) provides that “no person shall perform plumbing work unless that person is either” a licensed Master Plumber, a licensed journeyman plumber, or “[a]n apprentice registered pursuant to this Section who performs such plumbing work under the direction of a licensed plumber.” There are exactly two carve-outs (sec. 9-1003(2)(b)): a “helper or laborer performing ordinary unskilled labor (such as excavating, drilling, cleaning and moving) under the direction of a licensed plumber,” and “minor plumbing repairs” as defined in the Philadelphia Plumbing Code. The ladder is long: four years as a registered apprentice to sit the Journeyman examination, then a further year as a licensed journeyman before the Master Plumber examination, both examinations now administered by the International Code Council against the current Philadelphia Code. A Master Plumber must keep insurance on file, must have “a bona fide place of business” displaying the word “Registered” with the registration number “in letters not less than three inches high,” and gets a metal plate reading “Registered Master Plumber, Philadelphia.” Every licence is annual.
In ALLEGHENY COUNTY - which includes Pittsburgh - the licensing authority is not the city but the county HEALTH DEPARTMENT, under its Plumbing Code Article XV. The Plumbing Program “issues licenses for Apprentice, Journeyman, and Master Plumbers upon passage of the exam,” and “[l]icenses are renewed annually on the plumbers birthdate.” An apprentice registered at an accredited apprenticeship programme is issued an Apprentice Plumbers card that “allows the candidate to do plumbing as long as a journeyman plumber is present,” and every such card expires September 30 regardless of when it was issued. The Journeyman route is 576 hours of school plus four years of employment with a registered master plumber, then a $133.00 examination held twice a year; the Master route is two further full years as a journeyman, then a $265.00 examination. Renewals are $125.00 for a journeyman and $375.00 for a master, both on the licensee’s birthday. Applications now go exclusively through the county’s Accela Citizen Access Portal, and the examination is written against the 2022 version of Article XV. The City of Pittsburgh’s own Department of Permits, Licenses, and Inspections enumerates the licences it issues - General and Sign Contractors, and Electrical, HVAC, Stationary Power Engineer and Fire Suppression trade licences - and plumbing is deliberately absent from that list, because the county holds it.
On top of the local licence sits a statewide REGISTRATION that is not a licence and does not replace one. Under HICPA, “[n]o person shall hold himself out as a contractor, nor shall a person perform any home improvement without first registering with the bureau” - the Bureau of Consumer Protection in the Office of Attorney General - and the Attorney General’s FAQ says master plumbers are covered when they perform home improvements on private residences. Two different thresholds govern: work counts as a “home improvement” only where the total cash price agreed is more than $500, while a person is not a “contractor” at all if the total cash value of their home improvements was less than $5,000 in the previous taxable year. Registration requires liability insurance of at least $50,000 for personal injury and at least $50,000 for property damage, runs two years, and puts the registration number on every advertisement, contract, estimate and proposal - a home improvement contract is not even enforceable against the owner without it. The fee is where the sources part company: the statute says $50, the Attorney General’s current application form and instructions both demand $100, and the AG’s FAQ prints both numbers in different answers. And registration proves nothing about skill: the Attorney General states that “[r]egistration under HICPA is not an endorsement, recommendation or approval by the Office of Attorney General of the contractor’s competency or skill.”
Finally, the limits of this record. Pennsylvania has 67 counties and more than 2,500 municipalities and there is no statewide register of which of them license plumbers. Philadelphia, Allegheny County and the City of Pittsburgh are covered here because they are the bulk of the audience. Allentown, Erie, Reading, Scranton, Bethlehem, Harrisburg, Lancaster and the suburban Philadelphia counties were not checked and are asserted nowhere in this record.
What it’s called
Pennsylvania does not license plumbers at the state level; licensing is handled by cities and counties, so a search for a “Pennsylvania plumbing license” maps to a LOCAL licence. In Philadelphia the credentials are the Plumber Apprentice licence, the Journeyman Plumber licence and the Master Plumber’s License, all issued to the individual by the Department of Licenses and Inspections and all renewed annually - a Philadelphia master plumber is styled a “Registered Master Plumber” and receives a metal plate reading “Registered Master Plumber, Philadelphia.” In Allegheny County, which includes Pittsburgh, the same three tiers - Apprentice Plumbers card, Journeyman Plumber licence and Master Plumber’s License - are issued by the ALLEGHENY COUNTY HEALTH DEPARTMENT, not by the City, and each carries a “Health Permit Number” renewed on the licensee’s birthday; the City of Pittsburgh’s own trade licences cover electrical, HVAC, stationary power engineer and fire suppression work but not plumbing. Separately, the Pennsylvania Home Improvement Contractor registration issued by the Office of Attorney General - the “PA HIC number” or “PA number” that appears on residential contractors’ advertisements and contracts - is a REGISTRATION, not a licence: the Attorney General states that it “is not an endorsement, recommendation or approval… of the contractor’s competency or skill,” it involves no examination or experience requirement, and it does not substitute for a local plumbing licence. “PA plumbing license,” “Philadelphia master plumber license,” “Allegheny County plumbing license” and “Pittsburgh plumber license” all refer to one of these local credentials, never to a Commonwealth one.
Who does NOT need a license — exemptions
Pennsylvania licenses no plumbing occupation at state level, so the operative carve-outs are the ones written into the local codes and into the statewide registration statute. Read in full, they are:
PHILADELPHIA - the ONLY two exceptions to the plumbing licence, Philadelphia Code sec. 9-1003(2)(b): “This Section shall not prohibit a helper or laborer performing ordinary unskilled labor (such as excavating, drilling, cleaning and moving) under the direction of a licensed plumber, nor shall it prohibit any person from performing minor plumbing repairs as defined in Section 8-201.2.” Two limits travel with that sentence. The helper exception is bounded twice over - the labour must be ORDINARY UNSKILLED labour, and it must be performed UNDER THE DIRECTION OF A LICENSED PLUMBER - so it is not a route for an unlicensed person to work alone. And the second exception depends on a definition this record could not read: Title 8 was repealed in 1997 and the Code’s own editor’s note states that the “Section 8-201.2” material “now appears in Title 4, Subcode P, Chapter 2” - the Philadelphia Plumbing Code. That definition is NOT reproduced here because it was not read; do not substitute the City’s separate permit rule for it (see the next paragraph).
PHILADELPHIA - the separate PERMIT exemption, which is not a licence exemption. L&I: “A Plumbing Permit is not required for: Minor repairs with the same material. This includes replacing faucets, valves, and parts. Removing and re-installing toilets, if no pipes or fixtures will be replaced or moved. Stopping leaks and clearing stoppages.” That is a rule about permits. Whether the same work also falls inside sec. 9-1003(2)(b)’s “minor plumbing repairs” is a question the Philadelphia Plumbing Code answers, and this record does not.
PHILADELPHIA - exceptions to the SEPARATE Contractor licence, Philadelphia Code sec. 9-1004(3)(b): “The following persons shall not be required to obtain a license under this Section: (.1) owners who perform their own construction work either for the purpose of making improvements on a property they own and occupy or to allow for them to occupy a property they own. Such owners must be listed by the Board of Revision of Taxes as the owner of record for the property where the work is being performed. The Department may require other proof of property ownership from any person claiming an exception under this subsection; (.2) engineers or architects licensed by the Commonwealth of Pennsylvania; (.3) governmental employees performing construction activity for their governmental employer as part of their official duties. This exception does not apply to Contractors retained by a governmental entity; (.4) a Contractor already licensed by the Department; and (.5) a Contractor who does not perform any job for which the Contractor is paid more than five hundred dollars ($500).” And the scope line that keeps trade licensees out of this section altogether, sec. 9-1004(3)(e): “This Section shall not apply to persons holding journeyman or master trade licenses unless such persons also operate as a Contractor within the meaning of this Section.” Note that none of these is an exemption from the PLUMBING licence - an owner-occupant exempt from the Contractor licence is still governed by sec. 9-1003 for plumbing work.
PHILADELPHIA - who is outside the OSHA 10 rule. L&I requires OSHA 10 Construction of “[a]ll workers on a construction or demolition site,” and states that the requirement “does not apply to: Delivery people. Design professionals and their staff. Special inspectors. Workers that aren’t doing permit-regulated construction or demolition.” Separately, the OSHA 30 SUPERVISOR requirement “does not apply to: Plumbing contractors. Electrical contractors. Fire suppression contractors. Registered PA home improvement contractors (with no separate Philadelphia License).” Keep those two apart - plumbing contractors are outside the OSHA 30 supervisor rule but their workers are inside the OSHA 10 rule.
ALLEGHENY COUNTY - the Health Department’s published pages describe the Apprentice, Journeyman and Master licences and their renewal, but they do NOT publish a list of persons or work exempt from the plumbing licence requirement. That list, if it exists, lives in Article XV, which could not be read (see blockers). No exemption is asserted for Allegheny County in this record.
STATEWIDE - who does NOT need Home Improvement Contractor registration. The Act works by definition rather than by an exemption list, and there are two separate escape hatches plus a set of excluded activities. FIRST, the person: “Contractor… does not include any of the following: (1) A person for whom the total cash value of all of that person’s home improvements is less than $5,000 during the previous taxable year. (2) A home improvement retailer having a net worth of more than $50,000,000 or an employee of that retailer that does not perform home improvements.” SECOND, the job: work is a “home improvement” only where “the total cash price of all work agreed upon between the contractor and owner is more than $500,” and only in connection with “a private residence or a building or a portion of the building which is used or designed to be used as a private residence” - “[p]rivate residence” meaning “(1) A single family dwelling. (2) A multifamily dwelling consisting of not more than two units. (3) A single unit located within any multifamily dwelling, including condominiums and cooperative units.” THIRD, the excluded activities, sec. 2: “The term does not include: (i) The construction of a new home. (ii) The sale of goods or materials by a seller who neither arranges to nor performs, directly or indirectly, any work or labor in connection with the installation or application of the goods or materials. (iii) The sale of services furnished for commercial or business use or for resale, if the service takes place somewhere other than at a private residence. (iv) The sale of appliances, including stoves, refrigerators, freezers, room air conditioners and others which are designed for and are easily removable from the premises without material alteration. (v) Any work performed without compensation by the owner of the owner’s private residence or residential rental property. (vi) Any work performed by a landscaper certified by the Department of Agriculture under the… Plant Pest Act, except to the extent that the work involves” listed construction and drainage work at a private residence. “(vii) Emergency work pursuant to section 7 of the… Unfair Trade Practices and Consumer Protection Law. (viii) The conversion of existing commercial structures into residential or noncommercial structures.” FOURTH, sec. 13’s flat exemptions: “This act shall not apply to any of the following persons or organizations: (1) The Commonwealth, or any of its political subdivisions. (2) The Federal Government.” A definitional limit worth noting on the owner side: “A person who owns three or more private residences in this Commonwealth shall not be deemed an owner except with respect to the person’s primary residence or the part of the building which houses the primary residence of the owner and those private residences the person uses for personal recreational purposes.” And the Attorney General closes two doors people expect to find open: charities and non-profits get no exemption, and building superintendents and apartment/condominium/community-association maintenance staff are outside the Act only for “work on the property within the scope of their employment with these businesses” - private side work totalling $5,000 or more in a calendar year requires registration. None of these HICPA exemptions touches the Philadelphia or Allegheny County plumbing licence, which sec. 12 expressly preserves.
Where to get licensed
There is no statewide Pennsylvania board to call, so start from the place the work will be done.
IN PHILADELPHIA: apply to the Department of Licenses and Inspections through eCLIPSE, or in person by appointment at the Permit and License Center, 1401 John F. Kennedy Blvd., MSB Public Service Concourse, Philadelphia, PA 19102 (open 8 a.m. to 3:30 p.m. Monday through Friday; offices close at noon on the last Wednesday of each month). The ladder is Plumber Apprentice, then Journeyman Plumber, then Master Plumber’s License. Apprentice: submit a statement of current or prospective employment on company letterhead signed by the master plumber, plus a 2x2 colour photo; licence fee $25 (a non-refundable $20 application fee is applied toward it); you must be at least 16 and you must re-register if you change employers. Journeyman: four years registered as a Philadelphia apprentice (or a similar authorisation from another jurisdiction with equal or greater requirements, subject to L&I approval), plus the Journeyman Plumber Examination administered by the International Code Council; licence fee $126 (non-refundable $25 application fee applied). Master: one year as a licensed Philadelphia Journeyman (or an approved equivalent), plus the Philadelphia Master Plumber Examination from the International Code Council; licence fee $303 (non-refundable $50 application fee applied), renewal $253. For the Master licence also have ready a Business Income and Receipts Tax ID, a Commercial Activity License, a Certificate of Insurance (L&I’s live requirement is General Liability $500,000 per occurrence, Automobile Liability $300,000, and Workers’ Compensation at $100,000 per accident / $100,000 per employee / $500,000 policy limit - higher and broader than the $200,000 combined single limit in the Code), an employment statement if you are not self-employed, and current standing on all City taxes. Every licence renews annually and renewal requires City tax compliance; renewing more than 60 days late costs 1.5% of the licence fee per month. Watch the exam timing rule: the exam must reference the current version of the Philadelphia Code, or your application must be submitted within 12 months of passing. If your business will also perform “construction” beyond your trade scope, you may additionally need the separate Philadelphia Contractor license (Philadelphia Code sec. 9-1004, $100 application and $100 annual renewal) - it does not apply to journeyman or master trade licence holders “unless such persons also operate as a Contractor.” Every worker on a construction or demolition site needs OSHA 10 Construction, with proof kept on site. Code questions and product approvals go to the Plumbing Advisory Board, [email protected] , (215) 686-2419.
IN ALLEGHENY COUNTY, INCLUDING PITTSBURGH: apply to the ALLEGHENY COUNTY HEALTH DEPARTMENT Plumbing Program, 2121 Noblestown Road, Suite 207, Pittsburgh, PA 15205, 412-578-8036 (the old 3901 Penn Avenue office is closed) - not to the City. Applications for licences and for the examinations are submitted exclusively online through the Accela Citizen Access Portal; as of Spring 2026 the portal is the only route. Apprentice: register at an accredited apprenticeship programme and you are issued an Apprentice Plumbers card, which lets you do plumbing while a journeyman plumber is present; all cards issued in a calendar year expire September 30. Journeyman: 576 hours of school plus four years of employment with a registered master plumber, then the Journeyman Plumbers Examination, $133.00, offered twice a year (spring and fall) over two days; renewal $125.00 annually on your birthday. Master: two full years of work experience as a journeyman, then the Master Plumber Examination, $265.00; renewal $375.00 annually on your birthday. Submit the notarised work statement electronically with the exam application - do not mail or hand-deliver it. Study the 2022 version of Article XV, which the county states is the version the exam is written against, and confirm the current exam dates and application deadline with the office, because the published exam date on the county’s page can be stale. Note also that the Plumbing Division “will no longer be permitting partial lead line replacements or repairs to lead water service lines.” Permits and plans are filed through the Citizen Access Portal, and a representative of the plumbing contractor must be present at inspections. Pittsburgh’s own PLI ([email protected] , 412-255-2175) issues Electrical, HVAC, Stationary Power Engineer and Fire Suppression trade licences and General and Sign Contractor licences - not plumbing - so only deal with PLI if you also need one of those; its licences expire 365 days from issuance and trade licence holders need 8 CEUs a year.
EVERYWHERE IN PENNSYLVANIA, IF THE WORK IS RESIDENTIAL: register as a Home Improvement Contractor with the Office of Attorney General’s Bureau of Consumer Protection before you offer or perform the work. Apply online or by the mail-in form; the current form and its instructions require a non-refundable $100 check or money order payable to “Commonwealth of Pennsylvania” (the statute still says $50 - budget $100). You will need proof of at least $50,000 personal-injury and $50,000 property-damage liability insurance. Registration lasts two years and must be renewed biennially, and you must report any change in your registration information within 30 days. Put your number - formatted “PA” plus the digits - in every advertisement, contract, estimate and proposal; a home improvement contract is unenforceable against the owner without it. You are outside the requirement only if the total cash value of all your home improvements was less than $5,000 in the previous taxable year, or the job’s total cash price is $500 or less, or the property is not a “private residence” (single-family, two-unit, or a single unit in a multifamily building), or the work is new-home construction. Consumers verify registrations at the Bureau’s toll-free line, 1-888-520-6680. Registration is not a competency credential and does not substitute for a Philadelphia or Allegheny County plumbing licence.
ANYWHERE ELSE: contact the municipality where the work will be performed and that county’s health department. This record does not cover Allentown, Erie, Reading, Scranton, Bethlehem, Harrisburg, Lancaster, or the suburban Philadelphia counties, and the Philadelphia and Allegheny patterns must not be assumed to apply there.
