NV-C1 Cost Overview: What You're Actually Paying For
Getting licensed as a C-1 Plumbing and Heating Contractor in Nevada isn't a single line-item purchase - it's a sequence of fees that flow through two different organizations: PSI Services LLC, which administers the exam itself, and the Nevada State Contractors Board, which reviews your application and issues the license. Understanding the full sequence matters because paying for the wrong combination, or scheduling before Board approval, wastes money you can't easily recover.
This breakdown covers every fee tied specifically to the full C-1 Plumbing and Heating Contractor trade examination - not the narrower C-1d plumbing-only exam, which has its own separate scope. If you're still confirming which license classification applies to your work, review the NV-C1 Requirements 2026 guide before spending anything on scheduling.
PSI Exam Fees: $95 vs. $140 Explained
PSI administers the C-1 trade exam on a computer-based, open-book format. The fee structure depends on whether you're testing for the trade exam alone or pairing it with the Contractor Management Survey (CMS) business-and-law exam:
- $95 - one examination portion (the C-1 trade exam by itself, assuming you've already satisfied or separately scheduled the CMS)
- $140 - two portions, meaning the C-1 trade exam paired with the CMS exam in the same testing session
Most first-time applicants haven't taken the CMS yet, so budgeting for the $140 combined rate is the realistic default. The trade exam itself consists of 120 scored questions with a five-hour time limit, and PSI may insert 1 to 10 additional unscored experimental questions that count against your allotted time - meaning your actual working time per question is tighter than 120 questions over five hours would suggest.
Passing requires 84 correct answers, which equals 70%. Note that the CMS exam carries its own separate passing standard of 75% and tests entirely different content - business law, licensing statutes, and financial responsibility - so don't let CMS study material bleed into your C-1 trade preparation. For a full explanation of exactly what that 70% threshold requires in raw numbers, see the NV-C1 Passing Score breakdown.
Key Takeaway
Budget for the $140 combined-exam fee unless you've confirmed with PSI that you're only sitting for the trade portion. Paying twice for separate sessions costs more than the $45 difference once you factor in lost testing days.
Nevada Contractors Board Application and License Fees
Passing the exam is only half the financial commitment. The Nevada State Contractors Board charges its own fees independent of PSI:
- $300 application fee submitted to the Board for review
- $600 for your initial two-year license once approved
The Board also verifies experience before it approves your application for exam scheduling. Trade qualifiers ordinarily need four full years of qualifying journeyman, supervisory, or contractor experience within the preceding 15 years. Board-approved education can substitute for up to three of those four years, which is a meaningful cost-saver for candidates coming through formal trade programs rather than pure field experience. Financial statements, contractor bonding, and applicable insurance are also part of the application package and carry their own third-party costs outside PSI and Board fees. A closer look at eligibility mechanics is available in the NV-C1 Requirements guide.
Biennial Renewal and Ongoing Compliance Costs
Licensure isn't a one-time expense. Nevada C-1 licenses renew every two years, and each renewal cycle carries its own $600 fee - identical to the initial licensing cost. Beyond the renewal fee itself, licensees must maintain ongoing bond coverage and applicable insurance for the life of the license, not just at initial issuance. Skipping a renewal deadline or letting bond coverage lapse can jeopardize active license status, so this is a recurring line item to plan for in any long-term cost projection, not a one-time sunk cost.
Hidden Costs Candidates Forget to Budget For
The published fees above are only part of the real cost of becoming a licensed C-1 contractor in Nevada. Several less obvious expenses catch candidates off guard:
- Retake fees: A failed attempt means paying PSI's $95 or $140 fee again after a mandatory two-week wait. Three failed attempts voids your entire application, forcing you to restart the Board application process - and its $300 fee - from scratch.
- Reference materials: The exam is open-book, but only five specific references are permitted in the testing room: UPC 2018, UMC 2018, NFPA 54 (2012), NFPA 58 (2014), and NFPA 13 (2019). Sourcing current editions of all five, plus tabs for organizing them, is a real out-of-pocket cost separate from any exam fee.
- Study time opportunity cost: With 23 domains and heavily weighted areas like Drain, Waste, and Vents, unfocused studying burns weeks that a targeted plan would compress. See the NV-C1 Exam Domains 2026 guide for how the 120 questions are actually distributed.
- Bond and insurance premiums: These vary by provider and aren't fixed by PSI or the Board, but they're a mandatory recurring cost tied directly to maintaining license status.
Key Takeaway
The single most controllable cost in this entire process is the retake fee - and it's entirely avoidable with disciplined preparation. Review the How Hard Is the NV-C1 Exam? guide before deciding how much prep time to allocate.

Why Domain Weighting Should Shape Your Study Spending
Every dollar and hour you spend preparing should be proportional to how the 120 scored questions are actually distributed across the 23 domains. Studying evenly across all domains wastes money you've already committed through the $95 or $140 exam fee, because low-weight domains eat time that heavier domains need.
Drain, Waste, and Vents carries the single largest allocation at 10 items. Gas Systems, Water Supply, Traps and Interceptors, and Isometric Analysis/Plumbing Mathematics each carry 8 items apiece - together these five domains account for a substantial share of your total score before you even touch the remaining eighteen domains.
Drain, Waste, and Vents
The largest single domain at 10 scored items. Candidates must understand venting configurations, trap arm distances, and drainage fixture unit calculations well enough to apply them under open-book time pressure.
- Highest point value of any domain - under-preparing here is the costliest mistake on the exam
Gas Systems, Water Supply, Traps and Interceptors, Isometric Analysis/Plumbing Mathematics
Each carries 8 items. Together with DWV, these five domains represent the backbone of the exam's scoring weight.
- Isometric Analysis/Plumbing Mathematics tests calculation speed - practice reading riser diagrams before test day
On the lighter end, domains like Hydronics, Piping Valves and Controls, Sheet Metal, Industrial Piping, and Breathing Systems for Firefighters each carry only 3 items. Spending equal hours on these as you do on DWV is a poor use of the time you've already paid to convert into a license. A full item-by-item walkthrough of all 23 domains is in the NV-C1 Exam Domains 2026 guide.
A Budget-Conscious Study Timeline
Since a failed attempt triggers a mandatory two-week wait and costs another $95-$140, the most cost-effective study plan is one that front-loads the heaviest domains and reserves the final stretch for the five approved references - UPC 2018, UMC 2018, NFPA 54 (2012), NFPA 58 (2014), and NFPA 13 (2019) - since those are the only materials you'll actually have in the room.
Heaviest Domains First
- Drain, Waste, and Vents (10 items)
- Gas Systems (8 items)
- Water Supply (8 items)
Remaining High-Weight Domains
- Traps and Interceptors (8 items)
- Isometric Analysis/Plumbing Mathematics (8 items)
- General Plumbing Requirements (7 items)
Mid-Weight Domains and Reference Navigation
- Water Heaters/Venting, Chilled Water Piping (6 items each)
- Hangers and Supports, Safety, Fire Sprinklers, Storm Drainage (5 items each)
- Practice locating sections quickly in all five approved references
Lighter Domains and Timed Simulation
- Cover remaining 3- and 4-item domains (Boilers, Cleanouts, Solar, Backflow, Joints and Connections, Industrial Piping, Breathing Systems, Hydronics, Piping Valves and Controls, Sheet Metal)
- Run full five-hour timed simulations with permitted tabs and a compliant calculator

Frequently Asked Questions
The application fee is paid to the Nevada State Contractors Board for reviewing your eligibility, separate from PSI's exam fees. If you fail the exam and eventually exhaust three attempts, your application is voided and a new application - with a new $300 fee - is required to try again.
It depends on whether you're also sitting for the CMS business-and-law exam in the same session. Testing the C-1 trade exam alone costs $95; pairing it with the CMS in one sitting costs $140.
Renewal costs $600 per two-year cycle, the same amount as the initial license fee, and licensees must maintain bond and applicable insurance coverage continuously between renewals.
You must wait two weeks before retesting and pay the applicable PSI fee again. If you accumulate three failed attempts, your entire application is voided, requiring you to restart the Board application process and its $300 fee.
Yes. While four full years of qualifying journeyman, supervisory, or contractor experience within the preceding 15 years is the standard requirement, Board-approved education can substitute for up to three of those four years, which can shorten your timeline to eligibility.
