If you’re planning to do plumbing work in Nevada—whether you’re a homeowner tackling a DIY project or a professional looking to start a business—you’ve probably asked yourself: “Is a plumbing license required in the state of Nevada?” The short answer is yes, but the details matter. Getting this wrong could mean fines, legal trouble, or even unsafe installations. In this guide, we’ll break down exactly when a license is mandatory, who’s exempt, and how to become compliant—so you stay on the right side of the law and protect your home or clients.
Who Needs a Plumbing License in Nevada?
In Nevada, any individual or business performing plumbing work for compensation must hold a valid plumbing contractor’s license issued by the Nevada State Contractors Board (NSCB). This includes installing, repairing, or altering plumbing systems in residential, commercial, or industrial settings.
However, there are exceptions:
- Homeowners doing plumbing work on their primary residence may be exempt—but only if they live in the home and aren’t renting it out.
- Handymen can perform minor repairs (like fixing a leaky faucet), but cannot install new plumbing systems, water heaters, or sewer lines without a license.
- Employees working under a licensed contractor don’t need their own license—but the supervising contractor must be licensed and on-site for critical phases.
⚠️ Important: Even if you’re “just helping a friend,” if money changes hands (including barter), Nevada considers that “compensation”—and a license is required.
What Type of Plumbing License Does Nevada Offer?
Nevada doesn’t issue a standalone “plumber” license like some states. Instead, it uses a contractor classification system. For plumbing, you’ll need one of these:
| License Class | Scope of Work |
|---|---|
| C-1d | Domestic (residential) plumbing only |
| C-1 | General plumbing (residential + commercial) |
To qualify for either, you must:
- Have at least 4 years of journey-level experience in plumbing within the last 10 years
- Pass a trade exam (covering codes, safety, installation)
- Pass a business/management exam
- Provide proof of liability insurance ($100,000 minimum) and a surety bond ($25,000)
The NSCB requires applicants to document their experience with W-2s, pay stubs, or affidavits from licensed contractors. Self-employed time counts—but must be verified.
How to Get a Plumbing License in Nevada: Step-by-Step
Follow these 5 concrete steps to become a licensed plumbing contractor in Nevada:
- Verify Your Experience
Gather documentation proving 48 months of full-time plumbing work. At least 24 months must be in Nevada or a reciprocal state (CA, UT, AZ). - Complete the Application
Submit Form B-1 through the Nevada State Contractors Board portal. Include:- Experience verification forms
- Proof of insurance and bond
- $300 application fee
- Schedule and Pass Exams
- Trade Exam: 115 questions, 4.5 hours, 70% passing score

Study materials are available through PSI Services, the NSCB’s testing vendor.

💡 Pro Tip: Nevada has reciprocity agreements with California, Utah, and Arizona. If you’re licensed in one of those states with equivalent experience, you may waive the trade exam—but not the business exam.
Why Licensing Matters: Safety, Legality & Trust
Unlicensed plumbing isn’t just illegal—it’s dangerous. According to the National Association of Home Builders (NAHB), 32% of plumbing-related insurance claims stem from work done by unlicensed individuals. Common issues include:
- Cross-connections contaminating drinking water
- Improper venting causing sewer gas leaks
- Faulty water heater installations leading to fires or explosions
Licensing ensures plumbers understand:
- Uniform Plumbing Code (UPC) standards
- Local amendments (e.g., Las Vegas requires backflow prevention devices)
- Earthquake-resistant piping rules in seismic zones
Moreover, licensed contractors carry insurance—so if something goes wrong, you’re protected, not liable.

Common Misconceptions About Nevada Plumbing Licenses
Let’s clear up some myths:
❌ Myth: “I only do small jobs—I don’t need a license.”
✅ Truth: If you’re paid—even $20—for any plumbing service beyond basic maintenance (like unclogging a drain), you need a license.
❌ Myth: “My general handyman license covers plumbing.”
✅ Truth: Nevada does not have a “handyman license.” All specialty work (plumbing, electrical, HVAC) requires its own classification.
❌ Myth: “I can subcontract under a licensed plumber without being licensed myself.”
✅ Truth: Only if you’re a W-2 employee. Independent subcontractors must hold their own license.
Penalties for Working Without a License in Nevada
The NSCB takes unlicensed contracting seriously. Penalties include:
- Fines up to $10,000 per violation
- Mandatory restitution to the client
- Criminal misdemeanor charges (for repeat offenses)
- Inability to sue for payment—even if the work was completed
In 2024 alone, the NSCB issued over 200 cease-and-desist orders to unlicensed plumbing operators, mostly in Clark and Washoe counties.
