Does Nebraska License Plumbing Contractors? What the Business Needs Instead

Only locally — with one statewide registration.

Nebraska has no state plumbing contractor license: state law instead requires anyone who installs or repairs sanitary plumbing to be a master plumber licensed by the city or village nearest the construction site, with employees licensed as journeymen by that city or village; full-time in-house staff of a single employer are exempt.

What the state does require of the business is contractor registration: all contractors and subcontractors doing business in Nebraska must register with the Nebraska Department of Labor under the Contractor Registration Act, and the department says registration does not ensure quality of work or protect against fraud.

Outside city limits, sanitary plumbing in buildings other than single-family homes and farm or ranch structures needs a permit from the nearest city or village, and the 2018 Uniform Plumbing Code applies where that city has no plumbing ordinance.

No state agency issues a plumbing contractor license, so Nebraska has no state license classes to choose between.

The statute's structure is local: cities of the metropolitan class — Omaha — must have a plumbing board, primary-class cities such as Lincoln may have one, as may smaller cities and villages, and these boards examine and license plumbers.

Omaha's plumbing licenses run Master Plumber, Journeyman Plumber and Apprentice Plumber, with the apprentice license subject to board approval; Lincoln's yearly plumbing registrations run Master Plumber Contractor, Master, Journeyman and Apprentice, and the city also licenses gas fitters and water-conditioning contractors and installers.

The statewide body that does touch your business is the Nebraska Department of Labor, whose registered-contractor list is searchable by the public.

The registration pages we read attach no qualifier to it: the Department of Labor registers the business, and registration is not a competency license.

What Nebraska requires instead is a person: the master plumber who installs or repairs sanitary plumbing must be licensed by the city or village nearest the site, and that license is the one the business works through.

In Omaha, sitting the master plumber exam takes four consecutive years of experience while holding an Omaha journeyman license, an equivalent master license from a similar-size city, or 12 years and 21,000 hours where no instruction was required.

Whether one master may qualify several firms, and how quickly a replacement must be named, was not verified for Omaha or Lincoln — put that question to the city licensing office before you structure the company around one person.

None at the state level: with no state plumbing contractor license, there is no state trade exam and no business-and-law exam.

The exams are the city plumbing board's.

In Omaha the Plumbing Board writes and gives its own exams, with plans, written and practical parts — passing takes 80% on each part for the master exam and 75% for journeyman — and exams are given in February, May, August and November, with test fees of $54 for journeyman and $81 for master.

Sitting the Omaha journeyman exam takes one of several routes: a four consecutive year apprenticeship program certified by the city, equivalent instruction plus on-the-job training, 7 consecutive years with at least 300 hours each (7,000 hours total), a journeyman license from an equivalent-size city, or 8 years and 14,000 hours where no instruction was required.

Lincoln's requirements for its plumbing licenses were not covered in our research; ask the city.

With no state plumbing contractor license, there is no state bond to post.

The statewide obligation that touches insurance is different in kind: a contractor with one or more employees must keep a current workers' compensation certificate of insurance (ACORD 25) on file with the Department of Labor or be removed from the registered list.

The bond rule the research confirmed is a city rule: in Omaha, a Master Plumber must carry a minimum $10,000 bond and $1,000,000 insurance.

Lincoln's bond and insurance amounts were not captured in our research — ask the city before you sign work.

The statewide cost is the registration fee: $40 a year, effective August 1, 2026, paid to the Department of Labor.

City credentials carry their own fees and cycles — under the statute, municipal plumbing licenses run one or two years from issuance as the local plumbing board determines.

Omaha's Master Plumber license starts at $100 plus an $8 tech fee (exam required) and renews at $75 plus $6 with 8 continuing-education hours; a Journeyman Plumber license runs $1 plus a $19.50 ID badge and a $1.64 tech fee, also with 8 CE hours, and an Apprentice Plumber license is $20 plus $1.60 with board approval.

Lincoln's yearly plumbing registrations are $250 for a Master Plumber Contractor, $75 for a Master, $50 for a Journeyman and $25 for an Apprentice, renewed between March 1 and May 31, with 10 CE hours required of a Master Plumber Contractor or Master Plumber and 6 of a Journeyman.

There is no state reciprocity to ask for: with no state plumbing contractor license, Nebraska has nothing at the state level to honor another state's license against.

The recognition the research confirmed sits in Omaha's exam application: a journeyman license from an equivalent-size city is one route to sit the Omaha journeyman exam, and an equivalent master license from a similar-size city is one route to the master exam.

That is exam eligibility, not license-for-license reciprocity — you still pass Omaha's board-written exam.

Lincoln's treatment of out-of-state plumbing credentials was not covered in our research; ask each city where you plan to work what it accepts before you bid.

At the state level, the registration pages we read attach no qualifier to lose: the Department of Labor registration is a registration, not a competency license.

At the city level, our research did not verify how Omaha or Lincoln handle a departed qualifier — whether one master plumber may qualify several firms, or what deadline applies to naming a replacement.

That gap matters, because a master-level city license is what stands in for the plumbing contractor license in Omaha and Lincoln.

Before your license holder gives notice, ask the city licensing office what its replacement steps and deadlines are.

Two cities anchor the research.

Omaha's plumbing board examines and licenses plumbers: Master Plumber, Journeyman Plumber and Apprentice Plumber, with board approval required for the apprentice license.

Lincoln runs a parallel plumbing program — yearly registrations from Apprentice ($25) through Master ($75) to Master Plumber Contractor ($250) — and also licenses gas fitters (Master $50, Journeyman $25, Apprentice $15) and water-conditioning contractors and installers.

Each of these is that city's credential, not a statewide one, and our research did not survey Nebraska's other municipalities, which may set their own rules.

Before you take a job, ask the building or plumbing department for that city or village what it requires of a plumbing business.
