Who Needs a License in Nevada?
Any business or person who performs plumbing work in Nevada must have a proper C‑1 plumbing and heating contractor license, unless their work qualifies for a limited exemption. The threshold is clear: If your project costs over $1,000, or requires a building permit, or involves plumbing, you need the state contractor’s license.
For example, replacing a sink for $850 might not require a license, but installing a new gas water heater that needs a permit always does. Even if your work is under $1,000, if it is categorized as plumbing, heating, or electrical, you still need a license.
According to the NSCB, the qualification applies equally to residential and commercial work. If you are a bona fide employee working directly under a licensed contractor, you do not need your own license. However, if you bid or contract work as a business, you do. General contractors may not perform plumbing unless they also hold the C‑1 (or relevant subclassification), per NAC 624.190. The only exemption for non-contractors relates to handyman work under $1,000, with no required permit and not involving specialty trades such as plumbing (see NSCB FAQ Central).
Plumbing License Types
The only mandatory classification for most plumbing work in Nevada is the C‑1, “Plumbing and Heating Contracting” license. This license covers a broad range of plumbing projects for both residential and commercial work. All applicants for plumbing work must apply for this C‑1 category or one of its specific subclassifications, as needed.
C‑1 (Plumbing and Heating Contracting): This is the primary license and covers installation, maintenance, and repair of all plumbing and heating systems (see complete definition in NAC 624.190).
C‑1a: Boilers, hot water and steam heating systems, including all necessary piping and valves.
C‑1b: Fire sprinkler systems, the fabrication and installation of piping, controls, and fire-specific systems.
C‑1c: Insulation of pipes and ducts.
If you hold a C‑1, you are authorized to perform any work that fits any of these subclassifications. These are not separate licenses, but specializations under the main C‑1. There is no substitute: a general contractor license (e.g., Class B) cannot be used in place of a C‑1 license for plumbing. You must also have four full years of qualifying experience in the C‑1 trade area prior to application.
Plumbing License Requirements in Nevada: How to Get Licensed
Getting your plumbing license in Nevada follows a strict process. Here are the required steps to earn a C‑1 license as a contractor:
Check Your Experience: Confirm you (or your qualifier) have at least four full years of experience as a journeyman, supervisor, or contractor in plumbing (C‑1). Experience within the last 15 years counts (see requirements).
Gather Documentation: Prepare “Certificates of Work Experience” (minimum four), a resume of your plumbing trade experience, and any supporting transcripts or apprenticeship certificates if using education to substitute for experience (can count toward up to 3 of the four required years).
Complete Application and Pay Fees: Fill out the current NSCB Contractor License Application and submit with the $300 non-refundable application fee. Include your experience details, background disclosure, and a financial statement (CPA-prepared if limit over $10,000).
Board Review: The board reviews your documentation. If approved, you will receive an Examination Eligibility form and a Candidate ID number allowing you to schedule exams.
Schedule Exams: Using your eligibility form, book the Business & Law (CMS) exam and C‑1 trade exam through PSI Licensure. Exam fees are $95 for each portion, or $140 for both portions taken together.
Pass the Exams: Take and pass both license exams (see more details on exam format below). You may take up to three attempts; a two-week wait is required between attempts. If you fail three times, your application is void and you must reapply after 30 days.
Submit Bond and Fees: After passing exams, the Board sets your specific bond requirement. Provide a surety bond or cash deposit. Pay the $600 biennial license fee, plus the Recovery Fund assessment (if you will perform residential work), and $200 admin fee if using a cash bond.
Provide Proof of Insurance or Exemption: You must show proof of Workers’ Compensation/Industrial Insurance, or fill out an exemption affidavit. This step is required before your license can be issued.
License Issued: After all items are verified and payment received, your Nevada plumbing contractor license is issued. It is valid for two years from the date of issuance. Renewals can be processed online.
All official forms, instructions, and complete requirements are posted on the NSCB website. Allow several weeks or more for application review, depending on exam scheduling.
Submitting Your Application
The application can be downloaded from the board's site. Complete all personal, business, and qualifying individual sections. Attach experience and supporting documents. The application fee must be included at time of filing; make checks payable to the Nevada State Contractors Board.
Board Review and Exam Authorization
The Board evaluates your experience and supporting materials. If qualified, you are sent a Candidate ID and eligibility form. Only then can you register for exams with PSI.
Bonds, Insurance, and Final Steps
After successful examination, you must post a contractor bond (amount set by Board, typically between $1,000 and $500,000), supply evidence of insurance (or exemption), and settle all remaining license, admin, and fund fees before your license is activated.
Application Requirements
You must meet very specific standards to qualify for a Nevada C‑1 plumbing license, primarily experience, financial, background, bond, and insurance requirements.
Experience and Age Requirements
The key experience requirement is four full years, in the preceding 15, engaged in the plumbing trade as a journeyman, supervisor, or contractor. Work in related areas must be documented. You need to submit four certificates of work experience (or a master’s certificate, or proof of relevant military experience). Formal education, such as apprenticeships or technical training, can count for up to three of those years if supported by transcripts.
The board does not publicly specify a minimum age or citizenship requirement, but these details are captured within the application form. You should verify these with the Board directly if you have questions.
Financial Statements
You must submit a financial statement. If your desired monetary limit is $10,000 or more, this must be CPA-prepared. Otherwise, you may use the Board’s personal financial statement form. The statement is used to set your bond amount and overall license limit.
Bond and Insurance
All contractors must obtain a bond. The Board sets the amount (minimum $1,000 up to $500,000 or more depending on work volume and exposure). You may post a surety bond or a cash deposit (which requires a $200 administration fee). For those serving residential owner-occupied homes, the Recovery Fund assessment applies at $200/$500/$1,000 depending on the project limit.
You must show proof of Workers’ Compensation (Industrial Insurance) or submit an affidavit for exemption if ineligible. This rule applies if you have employees.
Background Disclosure
You must submit an Applicant Background Disclosure Statement. The form requires that you fully disclose any criminal convictions or relevant legal actions. While a background check is mandatory, fingerprinting is not stated on the NSCB site; verify any further requirements at the board.
Exams
To fulfill plumbing license requirements in Nevada, you must pass two exams: a Business and Law (CMS) test and a trade exam specific to the C‑1 Plumbing classification. Both are required for initial licensure.
Exam Format and Administration
The exams are administered in-person at PSI testing centers. Both tests are multiple-choice. While the NSCB does not state if exams are open book, official candidate exam bulletins available on the PSI site give the most current policies. The number of questions and passing score are not made public; verify details directly in the candidate bulletin at the exams page. Exam eligibility is granted only after the NSCB has reviewed and approved your experience credentials.
Retake Policy
Contractors are allowed up to three attempts for each exam section. There is a mandatory two-week waiting period between attempts. If you fail any portion three times, your application is void, and you must wait 30 days to reapply.
Exam Fees
As of March 2026, exam fees are $95 per portion, or $140 for both Business & Law and plumbing trade if taken together. These are paid directly to PSI at the time you schedule your test.
Fees
The costs for the plumbing license requirements in Nevada are well defined, but bond amounts and some penalty fees vary with your application.
Application Fee: $300 (non-refundable) (as of May 2010 to present, verify on NSCB fee schedule).
Biennial License Fee: $600 (payable at license issuance and renewal; see NSCB).
Examination Fees: $95 for either CMS or trade exam; $140 for both portions (as of March 2026, source: PSI Bulletin).
Residential Recovery Fund Assessment: $200 for limits up to $1,000,000; $500 for over $1,000,000 but not unlimited; $1,000 for unlimited license (as of March 2026, see Board).
Bond: $1,000 to $500,000 (set after application; amount depends on license type, limit, and board discretion; verify at NSCB).
Cash Bond Administration Fee: $200 (as of March 2026, see NSCB).
Reinstatement or Late Fees: Statutes allow reinstatement within 6 months of suspension by paying renewal plus board fixed fee; specific amount not stated (NRS 624.283).
For any fees not listed above, or for the current fee schedule and forms, always confirm directly at the official NSCB site under General Requirements & Fees.
Renewal and Continuing Education
The plumbing license requirements in Nevada specify a two-year (biennial) renewal period. There is currently no continuing education (CE) requirement for C‑1 or any plumbing-related license class under the NSCB.
Renewal Process
Your license will expire on the last day of the month in which it was originally issued, two years after the date of issuance. You must renew before this to remain in good standing. The renewal fee is $600 (plus the Residential Recovery Fund assessment, as applicable).
Consequences of Lapse
If your license lapses (is not renewed by its expiration date), it is suspended. You have six months to reinstate your license by paying the renewal fee and a board fixed reinstatement fee (fee amount not specified). If more than six months pass, you must reapply as a new applicant, starting the full process over. Until you reinstate, you cannot legally contract for plumbing work in Nevada.
No formal CE requirement is in place. You are not obligated to take ongoing training hours for renewal, but you must remain in compliance with all statutes.
Reciprocity
There is no formal reciprocity list for plumbing license requirements in Nevada. However, the NSCB has pathways for licensure by endorsement. If your qualifying (RMO) individual has held an equivalent license in another state for four years with no disciplinary action, the Board may waive the experience and trade exam. However, this only applies if your original state also has a trade exam considered equivalent by the Nevada Board. Otherwise, you must pass the Nevada trade exam for plumbing even if licensed elsewhere. Always consult the NSCB's State Equivalency Chart and verify with the Board directly (see details on endorsement).
