C-3 vs. R-3 vs. CR-3: Which Classification Do You Need?

Arizona separates the trade into commercial, residential, and dual classifications.

What Work Does the Arizona C-3 and R-3 Scope Cover?

Arizona allows these classifications to place the concrete footings and concrete slabs needed to install or repair specific exterior structures.

The scope includes:

• Window awnings.
• Door hoods.
• Freestanding canopies.
• Attached canopies.
• Carports.
• Patio covers.
• Metal shade structures.
• Fabric structures.
• Fiberglass covers.
• Plastic covers.
• Screened and paneled enclosures.
• Fascia panels.
• Flashing.
• Skirting.
• Certain exterior detached metal storage units.

For screened and paneled enclosures, at least 60% of the wall area must be constructed of screening material. The enclosure is not intended to become habitable living space.

The Storage-Building Limits Are Different

There is one easy-to-miss difference between the commercial and residential scopes.

CR-3 combines the applicable residential and commercial scopes, so contractors need to know which side of the license applies to the project.

Electrical, Plumbing and HVAC Are Not Included

The C-3 and R-3 scopes specifically do not allow the contractor to install or repair:

• Electrical systems.
• Plumbing systems.
• Air-conditioning systems.

That matters when patio covers start growing extra features.

A customer may want lighting, fans, receptacles, plumbing, misting equipment, or HVAC connected to an enclosure. Those systems can require properly licensed contractors outside the C-3, R-3, or CR-3 scope.

Current Arizona C-3, R-3 and CR-3 Exam Details

PSI currently lists the same basic exam specifications for all three classifications:

• 30 questions.
• 75-minute time limit.
• 70% minimum passing score.
• Open-book format using approved references.
• Computer-based PSI examination.
• Current trade-exam fee: $66.

Seventy-five minutes for 30 questions gives you an average of about two and a half minutes per question.

That is enough time to use the books, but only if you already know which book contains the information you need.

The Exam Breakdown

Metal roofing and concrete together make up 20 of the 30 questions.

If those two areas are weak, the exam gets uncomfortable very quickly.

Study Metal Roofing and Flashing First

With 12 questions, Metal Roofing, Flashing, Gutters and Downspouts deserves the largest share of your study time.

Review:

• Metal roof panels.
• Roof slopes.
• Panel installation.
• Fasteners.
• Seams.
• Flashing.
• Drip edges.
• Roof penetrations.
• Wall-to-roof intersections.
• Fascia.
• Gutters.
• Downspouts.
• Water drainage.
• Expansion and movement.

A patio cover is supposed to provide shade and weather protection. If the flashing sends rainwater into the wall, everyone suddenly becomes very interested in flashing details.

Know the Architectural Sheet Metal Manual

One of the most important references is the Architectural Sheet Metal Manual, 2012.

Become comfortable finding information on:

• Flashing details.
• Sheet-metal joints.
• Roof edges.
• Wall flashing.
• Gutters.
• Downspouts.
• Expansion.
• Metal fabrication.
• Water-shedding details.

Do not try to memorize every drawing. Learn the organization of the manual so you can locate the correct detail quickly.

Use the NRCA Roofing Manuals

The current PSI outlines include NRCA roofing references covering steep-slope and metal-panel roof systems.

These references support questions involving:

• Metal roofing.
• Roof connections.
• Flashing.
• Drainage.
• Roofing materials.
• Installation practices.
• Weather protection.

PSI currently recognizes multiple listed editions of these NRCA manuals, depending on the title.

Concrete Is More Important Than Many Candidates Expect

Concrete accounts for eight questions, or more than one-quarter of the examination.

The classification allows contractors to place concrete footings and slabs as required for the structures they install.

Study:

• Footings.
• Slabs.
• Forms.
• Reinforcement.
• Concrete placement.
• Consolidation.
• Finishing.
• Curing.
• Anchor locations.
• Dimensions.
• Basic concrete calculations.

Pay special attention to how posts and support structures transfer loads into concrete footings.

Study Awnings and Screened Enclosures

Six questions focus directly on awnings and screened enclosures.

Review practical concepts such as:

• Layout.
• Framing.
• Posts and supports.
• Fasteners.
• Anchoring.
• Roof connections.
• Screen installation.
• Door installation.
• Panel installation.
• Weather protection.
• Materials.
• Maintenance.

PSI's current reference lists include Building Screened Rooms: Creating Backyard Retreats, Screening in Existing Structures, A Complete How-to Guide.

Do not dismiss a practical construction book because it looks less impressive than a code book. Six questions are six questions.

Know Your Carpentry Basics

Carpentry and Building Construction, 2016 is another current PSI reference.

Review:

• Framing.
• Layout.
• Measurements.
• Fasteners.
• Structural connections.
• Roof framing.
• Posts.
• Beams.
• Bracing.
• Construction materials.

Many patio-cover questions become much easier when you understand how a structure carries loads from the roof down to its supports and footings.

C-3, R-3 and CR-3 Use Slightly Different Code Lists

The current exam outlines share the same question count and subject breakdown, but the exact reference list varies slightly by classification.

Current CR-3 Reference List

The latest PSI CR-3 outline lists:

• Building Screened Rooms: Creating Backyard Retreats, 2004.
• Architectural Sheet Metal Manual, 2012.
• Carpentry and Building Construction, 2016.
• 29 CFR Part 1926 OSHA, latest available amendments, or the approved PSI selections.
• Gypsum Construction Handbook, 7th Edition, 2014.
• International Residential Code, 2015.
• International Building Code, 2015.
• NRCA Roofing Manual: Steep-slope Roof Systems, approved listed editions.
• NRCA Roofing Manual: Metal Panel and SPF Roof Systems, approved listed editions.

Candidates preparing for the dual exam can review the Arizona CR-3 Awnings, Canopies and Patio Covers Exam Book Package.

Prepare Your Open-Book References Correctly

PSI currently allows approved references to be prepared before the examination.

You may generally:

• Highlight the books before the exam.
• Underline material before the exam.
• Annotate approved references before the exam.
• Index the books before the exam.
• Use permanent tabs.

You may not write, highlight, underline, or add indexing while the examination is in progress.

PSI also prohibits additional loose or attached papers.

Temporary tabs such as Post-it notes and removable flags are not allowed.

Permanent tabs must be the type that would tear the page if removed.

Consider Highlighted and Tabbed References

You only have 75 minutes, so reference speed matters.

Candidates who want organized dual-license references can review the Arizona CR-3 Highlighted & Tabbed Book Package.

Highlighting and permanent tabs do not magically answer the questions. They simply reduce the amount of time you spend wondering whether flashing details are buried on page 90 or page 390.

Do Not Ignore OSHA

OSHA Safety contributes four questions.

Study construction hazards involving:

• Ladders.
• Scaffolds.
• Fall protection.
• Personal protective equipment.
• Hand tools.
• Power tools.
• Electrical hazards.
• Material handling.
• Concrete operations.
• Jobsite housekeeping.

Four questions can be the difference between passing and scheduling another exam.

Practice Basic Construction Math

Be comfortable with:

• Area.
• Volume.
• Square footage.
• Concrete quantities.
• Roof slope.
• Measurements.
• Material quantities.

PSI currently allows a silent, nonprinting, non-programmable calculator.

Practice with the same type of calculator before exam day. A calculator is most helpful when you already know which numbers belong in the formula.

Use a Three-Pass Testing Strategy

With only 75 minutes, time management matters.

1. Pass One: answer questions you know immediately.
2. Pass Two: handle questions requiring quick, targeted reference lookups.
3. Pass Three: return to calculations and difficult searches.

Do not let one strange flashing question eat ten minutes.

Ten minutes is enough time to answer several easier questions and still wonder why you spent so long arguing with a downspout.

A Practical Study Schedule

Use the exam weighting to build your plan.

1. Review the current PSI outline for your exact classification.
2. Study metal roofing and sheet-metal work.
3. Study flashing, gutters, and downspouts.
4. Study concrete footings and slabs.
5. Study awnings, canopies, and screened enclosures.
6. Review carpentry and framing.
7. Study the applicable IBC or IRC sections.
8. Review OSHA safety.
9. Highlight and permanently tab approved references.
10. Practice finding answers by book and topic.
11. Complete mixed practice questions.
12. Complete full 30-question simulations within 75 minutes.

Arizona Experience Requirements

The current Arizona classification table lists:

• C-3: two years of qualifying hands-on and/or managerial experience.
• CR-3: two years of qualifying hands-on and/or managerial experience.
• R-3 without the optional trade exam: two years.
• R-3 with the optional trade exam: one year.

Candidates should document experience involving the actual trade, including installation, supervision, framing, awnings, canopies, patio covers, roofing connections, screened rooms, concrete support work, and related construction activities.

You Also Need the Arizona SRE

Most new Arizona contractor applicants also need the Arizona Statutes and Rules Training Course and Exam, or SRE.

The SRE:

• Is computer based.
• Is open book.
• Is completed online through GMetrix.
• Covers Arizona contractor statutes and administrative rules.
• Requires at least 70% to pass.
• Currently costs $61.

Arizona allows a limited SRE waiver when the proposed Qualifying Party has served as the qualifying party on an Arizona contractor license within the applicable previous five-year period.

What If You Fail the Trade Exam?

Current PSI rules require a 30-day waiting period before retaking an examination you did not pass.

Candidates receive three attempts.

After three failed attempts, a 90-day waiting period applies before another attempt.

The $66 trade-exam fee applies again when you register for another attempt.

Use a failed score as study information rather than immediately repeating the same preparation plan.

Passing PSI Does Not Automatically Give You a License

Passing the trade exam is an important step, but Arizona ROC still has to approve the contractor license.

The licensing process generally includes:

1. Select the correct C-3, R-3, or CR-3 classification.
2. Choose the Qualifying Party.
3. Meet the applicable experience requirement.
4. Pass the SRE unless a valid exemption applies.
5. Pass the required trade exam.
6. Complete required background checks.
7. Form or register the legal business entity where required.
8. Obtain the required Arizona contractor license bond.
9. Pay the applicable state licensing fees.
10. Submit the complete application to the Arizona Registrar of Contractors.
11. Wait for ROC approval before performing work that requires the license.

Current Arizona License Fees

Arizona contractor licenses are issued for two-year periods.

• C-3 Specialty Commercial: current application and license fees total $580.
• R-3 Specialty Residential: current total is $720, including the Residential Recovery Fund assessment.
• CR-3 Specialty Dual: current total is $850, including the Residential Recovery Fund assessment.

These state-license totals do not include the trade exam, SRE, background checks, bond premium, business formation costs, or exam-preparation materials.

Frequently Asked Questions

Key Takeaways

• C-3 is commercial, R-3 is residential, and CR-3 combines both scopes.
• All three current PSI exams contain 30 questions, allow 75 minutes, and require 70% to pass.
• Metal Roofing, Flashing, Gutters and Downspouts is the biggest section with 12 questions. Concrete is second with eight questions.
• The exams are open book, but the exact reference list differs slightly between C-3, R-3, and CR-3. Check the PSI outline for your exact classification.
• Passing the trade exam is only part of licensing. Applicants must also satisfy Arizona's applicable SRE, experience, Qualifying Party, background, bonding, business, fee, and ROC approval requirements.

Final Thoughts

Passing the Arizona C-3, R-3, or CR-3 Awnings, Canopies and Patio Covers exam becomes much easier when you study according to the real PSI outline instead of trying to memorize an entire shelf of construction books.

Start with Metal Roofing, Flashing, Gutters and Downspouts. That category alone represents 12 of the 30 questions. Learn sheet-metal details, roof connections, drainage, flashing, gutters, downspouts, and common installation practices.

Then move to concrete. Eight questions is a large piece of a 30-question exam. Understand footings, slabs, reinforcing, placement, finishing, curing, measurements, and the way shade structures connect to their supporting concrete.

Next, study the actual specialty work. Learn awnings, canopies, patio covers, framing, fasteners, supports, screened enclosures, fascia, skirting, and common construction methods.

Do not leave OSHA until the night before the exam. Four safety questions can easily decide whether your score ends up above or below 70%.

Your books should also become familiar tools. The exam is open book, but you only have 75 minutes. Highlight important material before the test, add permanent tabs where allowed, learn the indexes, and practice choosing the correct reference before you begin searching.

Finally, remember that C-3, R-3, and CR-3 are similar but not identical. Their scopes differ, their experience paths can differ, and the current reference lists differ slightly. Always prepare for the exact classification on your PSI appointment.

When you are ready to prepare, start with the Arizona Contractor Exam Prep collection and compare your materials with the current PSI outline. Organized books, solid trade knowledge, and repeated 75-minute practice sessions can make a short exam feel much more manageable.
