Two closed binders and a pen on a conference table, Nevada Plumbing License: How to Start a Business

How to Start a Plumbing Business in Nevada

Last verified: November 5, 2026

Forming the LLC is the easy part. You cannot bid a plumbing job in Nevada until the State Contractors Board licenses your business, and that application is where the real work sits. This guide puts the steps in the order the Board needs them: classification, entity, qualifier, financial statement, exams, bond, then taxes. Every fee and rule below is from a statute or a Board page, and where we could not source a number we say so.

What You Need Before You Start

The plumbing license is the gate, and the LLC only exists to feed it. The Nevada State Contractors Board will not open an application without a Nevada Business ID, so you form the entity first and spend the rest of your time on the license file. Four things decide whether you get through it:

  • Experience: the person who qualifies the license needs at least four full years as a journeyman, supervising employee or contractor in the classification, within the 15 years before you apply (Nevada State Contractors Board: license requirements).
  • A Nevada Business ID: it comes with your state business license, so file the entity first.
  • A financial statement: required for every applicant, whatever monetary limit you ask for.
  • A bond: the Board sets the amount after it approves you, from $1,000 to $500,000.

If you are a handyman who does some plumbing today, read how to start a handyman business in Nevada first. The small-job exemption does not cover plumbing (see Step 1).

Step 1: Pick the Plumbing Classification

The license is a "C-1" but the page that matters is the subclassification. Under NAC 624.190, C-1 is "plumbing and heating contracting." A C-1 license covers the work of every subclassification under it. The one most plumbing startups mean is C-1d (plumbing), which covers:

  • Fixtures and the water supply, plus sanitary waste and vent systems
  • Roof drainage and landscape irrigation systems
  • Hydronic heating systems up to 200,000 BTU
  • Systems that heat potable water, including solar
  • Gas supply piping, and piping for compressed air, vacuum and medical gas
  • Water and gas piping from the edge of the building to the utility meter

Boilers (C-1a), fire sprinklers (C-1b) and sheet metal (C-1e) are separate subclassifications. Decide before you apply, because your qualifier needs the four years in the classification you request, and the Board charges $300 to add a classification later (NAC 624.130). If you cannot tell which one fits, the Board takes questions through its license classification request form, and the full list is on its license classifications page.

No small-job loophole: Nevada exempts repair work under $1,000, but not when it is work "of a type performed by a plumbing" contractor, and not when a building permit is required (NRS 624.031 on the Contractors Board site). All contractors must be licensed before they bid, offer or negotiate a price (Contractors Board), and the Board states plainly that contracting without a license is a crime.

Step 2: Form the Entity and Get Your Business ID

The Board's application asks for a Nevada Business ID, which starts with "NV" and appears on your Nevada state business license. File through the Nevada ORION business portal (the state's SilverFlume filing system now redirects there). The state fees below come straight from statute:

ItemLLCCorporation
Articles filing fee$75 (NRS 86.561)$75 if authorized shares total $75,000 or less, higher above that (NRS 78.760)
Initial list of managers or officers$150 (NRS 86.263)$150 (NRS 78.150)
State business license$200$500 (NRS 76.100)
Annual list and license renewal$350 together$650 or more together, because the list fee rises with authorized stock

For a first-time plumbing contractor the LLC is the lower-cost route: $350 a year to keep it current against $650 or more for a corporation. The annual list and license are due by the last day of the month in which the entity was formed, and the $100 late penalty is listed in the Secretary of State's state business license FAQ. Our Nevada LLC guide walks through the filing, and you can compare LLC formation services in Nevada if you would rather not file it yourself.

Registered agent: every entity needs one with an actual Nevada street address (NRS 77.300). You can serve as your own if you live in Nevada. An agent for 10 or more entities must register as a commercial registered agent (NRS 77.320).

Step 3: Name Your Qualifying Party and Gather Proof

The Board licenses the business, not the person, but one individual has to qualify it. That person must be an owner, officer, member, manager or employee who is actively engaged in the business (Contractors Board: qualifying party FAQ). The Board counts years, not hours: you will not find a "12,000 hours" figure in its requirements. Proof of the four years is one of:

  • Four Certification of Work Experience forms for each trade qualifier
  • A current master's certification from a governmental agency in a similar discipline
  • Proof of transferable military experience

Training at an accredited college, university or equivalent program can replace up to 3 of the 4 years, with apprenticeship certificates or transcripts as proof. Every trade qualifier also submits a resume of experience. If you are licensed as a plumbing contractor in another state, ask about licensure by endorsement, which needs four years of active licensure in the other state with no discipline.

Plan for the day your qualifier leaves. If that person stops working for you, you must tell the Board in writing within 10 days and have an approved replacement within 30 days, or the license can be suspended or revoked (NRS 624.285). If your only qualified person is an employee, that is the exposure. That is our reasoning from the statute, not a Board statement.

Step 4: Prepare the Financial Statement and Choose a Monetary Limit

The monetary limit is the largest contract you may take on a single site for a single client. The type of financial statement depends on the limit you ask for (Contractors Board: financial requirements):

Monetary limitStatement the Board accepts
$25,000 or lessCPA-prepared statement, the Board's own form, or a software balance sheet with an accuracy affidavit
More than $25,000, under $500,000CPA compiled (within 6 months) or reviewed or audited (within 1 year)
$500,000 to under $1,000,000Compiled statement with full disclosures, or reviewed or audited
$1,000,000 or moreReviewed or audited by a CPA, plus a bank verification form

Choose the limit by the jobs you expect to bid in your first two years, not by what looks impressive. Raising it later costs $250 for a permanent increase or $75 for a single project, and a single-project request must be in 5 working days before you bid (NAC 624.130; NRS 624.220). If your own finances are thin, the Board lets another person or entity indemnify you, but that needs its own form, financial statement and bank verification.

Step 5: Apply, Pay and Pass the Exams

Apply through the Contractors Board license application. The 2026 application form lists a nonrefundable application fee of $300. Each person listed, including your qualifier, files a background disclosure and fingerprint authorization.

Each qualifier then sits two exams run by the Board's testing vendor, PSI: the general business and law (CMS) exam, which is open book, and the trade exam for your classification, which is closed book apart from certain code references. You cannot book either until the Board has your application and has verified your experience. Rules that trip people up:

  • You get three attempts per exam, with a two-week wait between attempts.
  • A third failure voids the application. You may reapply after 30 days with a new application and fee.
  • Qualifiers have 6 months from filing to finish all testing (NAC 624.600).
  • Exam fees are paid to PSI and are not published on the Board's pages. Check PSI's candidate bulletin for the amount.

The trade exam can be waived in some cases, such as a qualifier who has served on another Nevada license in the same classification within the last 4 years (Contractors Board: examinations).

Step 6: Post the Bond

After approval, the Board tells you the bond amount, set by your financial strength, experience and monetary limit (NRS 624.270). You file it before the license is issued. It must come from a surety authorized in Nevada whose long-term obligations are rated A or better, and it must be continuous. A surety can cancel on 60 days' notice, and a lapse is cause to suspend the license.

You can post a cash deposit instead of a bond. The Board charges a $200 biennial administrative fee on cash deposits and holds the money for 2 years after the license ends (Contractors Board: bond requirements). What a surety charges you for the bond is not published anywhere official, so ask two or three sureties once the Board names the amount. We cannot give you a premium figure we could source.

Step 7: Keep the License Alive

  • Term: licenses last 2 years. A license that is not renewed on time is automatically suspended, and reinstatement within 6 months needs the renewal fee plus a reinstatement fee (NRS 624.283).
  • Fee: NAC 624.130 lists $600 to issue or renew a license. The amendment history of that regulation ends in 2012, so confirm the current figure with the Board when your application is approved.
  • Renewal: done in the Board's online renewal portal, using your license number and Nevada Business ID.
  • Your trucks: every commercial vehicle registered in your name must show your name and license number in letters and numbers about 1 1/2 inches high (NRS 624.288).

Step 8: Register for Federal and State Taxes and Insurance

  • EIN: free from the IRS. Skip sites that charge for it.
  • Modified Business Tax: if you hire, the Department of Taxation says all employers must file, and the general business rate is 1.17% of quarterly wages above $50,000 (Nevada Department of Taxation: Modified Business Tax, rates effective July 1, 2023).
  • Commerce Tax: it applies only to Nevada gross revenue over $4,000,000 a year, and construction (NAICS 23) has its own rate category under NRS 363C.340. A business at or under the threshold files nothing (Nevada Department of Taxation: Commerce Tax).
  • Sales tax permit: $15 per location if you sell taxable goods (Nevada Department of Taxation: start and run a business). Ask the Department how sales tax applies to the parts on your plumbing jobs before you price your first one.
  • Workers' compensation: employers with employees fall under Nevada's industrial insurance chapters (NRS 616A and following).

The Board's license requirements page lists a bond, not a general liability policy. Even so, ask any commercial or property-manager customer whether their contract demands a certificate of insurance before you bid, and talk to an insurance broker about general liability and commercial vehicle cover.

What It Costs

The published fees that every LLC plumbing contractor pays up front add to $1,325 ($75 + $150 + $200 + $300 + $600). That figure leaves out the bond premium, exam fees, insurance, tools and a vehicle. After year one the state side repeats at $350 a year for the entity, plus the Board's license renewal every 2 years.

Where Plumbing Startups Go Wrong

These points are our reasoning from the rules above, not a count of Board complaints.

  • Quoting before you are licensed: the rule covers bidding and negotiating, not just doing the work. Do not send a written quote for plumbing work until the license is issued.
  • Asking for a limit you cannot document: a larger limit needs a CPA-prepared statement. Start with the limit your books support.
  • Relying on one qualifier: see Step 3. Have a second qualified person in mind.
  • Letting the bond lapse: a lapse is grounds for suspension, so put the surety renewal date in your calendar next to the license date.
  • Treating the state business license as a trade license: it lets you operate a business. It does not let you do plumbing work. The Nevada contractor license guide covers the Board process for every classification, and the Nevada business license guide covers the state side.

What This Guide Does Not Cover

We could not confirm a bond premium, the PSI exam fees or any local permit and trade-card rules. Cities and counties, including Las Vegas, Henderson and Reno, set their own business license and permit requirements for the jurisdictions where you work, and some trade cards (such as a journeyman card) may be issued locally. Ask the building department in each place you plan to work. If you are comparing trades, the related guides cover electricians, roofers and painters. For a license or tax decision with money on the line, talk to the Contractors Board, a Nevada attorney or a CPA before you act. The Board's own staff are the only ones who can tell you whether your application will be approved.
