Exam Snapshot: The Numbers You Must Memorize
Before you touch a single practice question, lock in the mechanics of the North Carolina Residential Contractor License Exam (NC-RC). This is the fastest way to eliminate careless mistakes on test day. The exam is governed by the North Carolina Licensing Board for General Contractors and administered by PSI on a computer-delivered platform.
- Cost: $79 per attempt
- Format: Open-book, computer-delivered
- Scored questions: 90
- Unscored questions: 5 to 10 experimental items mixed in (you won't know which ones)
- Time limit: 3 hours 30 minutes
- Passing score: 70%
- Allowed tools: Approved references with permanent tabs, plus a silent nonprogrammable calculator
Because unscored experimental questions are blended invisibly into the 90 scored items, do not waste mental energy trying to identify "trick" questions - treat every question with equal seriousness. For a fuller explanation of how these numbers translate into real difficulty, read How Hard Is the NC-RC Exam? Complete Difficulty Guide 2026, and for the exact scoring mechanics see NC-RC Passing Score 2026: Exactly What You Need to Pass.
All 10 NC-RC Domains at a Glance
The NC-RC blueprint covers ten content areas spanning fieldwork, code knowledge, and business practices. Knowing the relative weight of each domain helps you allocate study time intelligently instead of spreading effort evenly across topics that don't carry equal exam value.
Domain 7: Estimating, Plan Reading and General Residential Code Requirements
This is the single largest official area, carrying 16 scored questions - nearly one-fifth of the entire scored exam.
- Reading residential plans and specifications accurately
- Quantity takeoffs and cost estimating logic
- General code requirements tied to the 2018 North Carolina Residential Code
The remaining nine domains round out the blueprint:
- Domain 1: Site work, Footings and Foundations
- Domain 2: Concrete and Concrete Reinforcement
- Domain 3: Masonry
- Domain 4: Carpentry
- Domain 5: Associated Construction trades, including Energy Conservation and Drywall
- Domain 6: Roofing
- Domain 8: OSHA Safety
- Domain 9: Licensing and Business and Law
- Domain 10: Special Construction Zones (wind and coastal) and Erosion and Sedimentation Control

Key Takeaway
Since Domain 7 (Estimating, Plan Reading and General Residential Code Requirements) has the most scored questions, prioritize plan-reading drills and code-lookup speed over any other single skill.
Licensing Tiers, Fees, and Project Limits
Passing the exam is only half the equation - you also need to understand the licensing structure the Board uses to authorize project size. Applicants must be at least 18 years old, demonstrate good moral character and financial responsibility, and designate a qualifier before the Board will process licensure.
| License Tier | Board Application Fee | Project Limit |
|---|---|---|
| Limited | $75 | $750,000 |
| Intermediate | $100 | $1.5 million |
| Unlimited | $125 | No limit |
Choosing the right tier before you apply matters - it determines both your upfront cost and the maximum contract value you can legally take on. For a complete breakdown of every fee, from the $79 exam charge to Board application costs, see NC-RC Certification Cost 2026: Complete Pricing Breakdown. If you're still confirming you meet the baseline eligibility criteria, review NC-RC Requirements 2026: Eligibility, Prerequisites & How to Qualify before scheduling anything.
Renewal and Continuing Education Rules
Passing the exam is a one-time event, but keeping your license active is an ongoing requirement. Residential licenses renew annually, with a hard deadline of December 31 each year.
- Renewal deadline: December 31, annually
- CE requirement: At least one qualifier for a Residential license must complete 8 hours of continuing education per year
- CE breakdown: 2 mandatory hours + 6 elective hours
Missing the December 31 renewal or the annual CE hours can jeopardize your ability to legally contract, so build a recurring calendar reminder now - not after you've passed the exam. For how this renewal cycle factors into whether the license pays off over time, see Is the NC-RC Certification Worth It? Complete ROI Analysis 2026, and to understand where licensed residential contractors typically find work, browse NC-RC Jobs.
Code Edition and Approved References
The current PSI candidate bulletin was updated November 19, 2025, and the exam is built around the 2018 North Carolina Residential Code. Confirm you're studying the correct code edition - outdated review materials referencing a different code cycle will cost you points on code-based questions across nearly every domain, especially Domain 7.
Building Your Reference Tabs
Because the exam is open-book, your in-test speed depends entirely on how well you've organized your approved references beforehand.
- Tab sections by domain topic (footings, roofing, masonry, etc.) rather than by chapter number alone
- Use permanent tabs - loose sticky notes can fall out or be disallowed
- Practice locating specific code sections under a timer before test day
If you're unclear on how the exam is scored relative to these 90 questions, or want the exact math behind the 70% threshold, revisit NC-RC Passing Score 2026: Exactly What You Need to Pass.

Final-Week Review Schedule
In the last week before your scheduled test, shift from broad content review to targeted, domain-weighted repetition. Since Domain 7 carries the most scored questions, it deserves the most final-week attention, but don't neglect the safety and legal domains that are easy to underweight.
Estimating, Plan Reading and Code Requirements
- Drill plan-reading and takeoff problems since this domain has 16 scored questions
- Cross-check every code answer against the 2018 North Carolina Residential Code
Structural Domains
- Review Site work, Footings and Foundations; Concrete and Concrete Reinforcement; Masonry; and Carpentry
- Practice reference-tab lookups under a timer to simulate the 3.5-hour limit
Trades, Roofing, and Special Zones
- Cover Associated Construction trades, Roofing, and Special Construction Zones (wind and coastal) plus Erosion and Sedimentation Control
Safety and Business
- Finish with OSHA Safety and Licensing and Business and Law
- Run a full-length timed practice exam mirroring the 90-question, 210-minute format
Use short focused blocks rather than marathon sessions during this final stretch - a tired brain misreads code citations far more often than a fresh one. For a broader statistical picture of how candidates perform on this exam, see NC-RC Pass Rate 2026: What the Data Shows, and once you're ready to test your recall under real conditions, run a timed simulation on our practice test platform.
