Exam Details

The Arizona Plumbing, Including Solar Residential / Commercial Contractor (CR-77) exam path is designed for candidates pursuing the Arizona dual residential/commercial plumbing classification that includes solar. Candidates should prepare for plumbing code requirements, fuel gas code requirements, mechanical code topics, sprinkler system provisions, on-site wastewater treatment facility provisions, construction safety, and solar system piping concepts.

Plumbing exam preparation should include water distribution, drainage, waste and vent systems, fixtures, traps, cleanouts, pipe materials, fittings, valves, pipe supports, testing, inspections, water heaters, system layout, and code compliance. These topics are central to plumbing work in both residential and commercial environments and should be studied with the International Plumbing Code, 2018.

Fuel gas preparation should include gas piping, appliance connections, combustion air, venting, pipe sizing, installation requirements, shutoff valves, definitions, and fuel gas safety. These subjects should be reviewed with the International Fuel Gas Code, 2018. Because plumbing contractors may encounter gas-related work within the permitted scope, fuel gas code familiarity is an important part of preparation.

Mechanical preparation should include mechanical equipment, combustion air, ventilation, exhaust systems, and related requirements that may connect to plumbing, fuel gas, and solar work. The International Mechanical Code, 2018 supports this part of preparation and helps candidates prepare for questions where plumbing and mechanical systems overlap.

Sprinkler system preparation should include NFPA 13, NFPA 13D, and NFPA 13R. NFPA 13 supports installation of sprinkler systems, NFPA 13D focuses on sprinkler systems in one- and two-family dwellings and manufactured homes, and NFPA 13R applies to sprinkler systems for residential occupancies up to and including four stories in height. Candidates should understand the purpose of each sprinkler reference and practice locating information in the correct book.

Because this classification includes solar, candidates should also prepare for solar-related plumbing and piping concepts. Solar system preparation may include collection loops, system components, piping, installation practices, maintenance considerations, mounting, operating principles, and system coordination. Candidates should understand how water piping, mechanical components, and plumbing code topics may connect to solar system work.

The on-site wastewater treatment facility reference supports review of Arizona wastewater provisions. Candidates should practice using the On-site Wastewater Treatment Facility Provisions in Unified Water Quality Permit Rule, Arizona Administrative Code Title 18, Chapter 9, 2006, including definitions, rule organization, and wastewater-related requirements. This reference should be studied before the exam so candidates are not trying to learn its layout during the test.

Open Book Test

The Arizona CR-77 Plumbing, Including Solar residential/commercial contractor exam is an open book test. Candidates may bring specific approved references into the examination center. The approved references included with this package are Code of Federal Regulations - 29 CFR Part 1926 (OSHA), International Fuel Gas Code, 2018, International Mechanical Code, 2018, International Plumbing Code, 2018, NFPA 13: Installation of Sprinkler Systems, 2019, NFPA 13D - Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, 2019, NFPA 13R - Sprinkler Systems for Residential Occupancies up to and Including Four Stories in Height, 2019, and On-site Wastewater Treatment Facility Provisions in Unified Water Quality Permit Rule, Arizona Administrative Code Title 18, Chapter 9, 2006.

Open book does not mean the exam is simple. Candidates must be able to identify the subject being tested, choose the correct reference, locate information efficiently, and apply the answer to the question. The approved books are most useful when the candidate has practiced using them before the exam.

Approved references may be highlighted, underlined, annotated, and indexed before the examination session. Candidates may not write, highlight, underline, or add indexing during the exam. Book preparation should be completed before test day so the materials are ready for use during the timed examination.

References may be tabbed or indexed with permanent tabs only. Permanent tabs are tabs that would tear the page if removed. Temporary tabs, removable sticky notes, loose papers, and extra attached papers are not allowed. This package supports preparation by providing books that are highlighted and tabbed for exam preparation.

For this exam, candidates should practice using every reference in the package. Plumbing questions may require the International Plumbing Code. Fuel gas questions may require the International Fuel Gas Code. Mechanical or solar-related questions may require the International Mechanical Code. Sprinkler questions may require NFPA 13, NFPA 13D, or NFPA 13R. Wastewater questions may require the Arizona Administrative Code wastewater provisions, and safety questions may require OSHA 29 CFR Part 1926.

Strong open-book preparation includes learning how each book is organized, using the index, reading definitions, locating tables, following exceptions, and confirming requirements before selecting an answer. The highlighted and tabbed books included in this package help support faster navigation, but consistent study and practice are still important.

Licensing Steps

Arizona contractor licensing is regulated by the Arizona Registrar of Contractors. Candidates pursuing the CR-77 Plumbing, Including Solar residential/commercial contractor classification should prepare for the required exam path and complete the contractor licensing application process connected to the classification.

The licensing process generally begins with confirming that the CR-77 classification matches the work the contractor intends to perform. Arizona contractor licenses are classification-specific, so selecting the correct classification is important. The CR-77 classification is intended for contractors seeking a dual residential and commercial plumbing scope that includes solar-related plumbing work within the permitted classification.

After confirming the correct classification, candidates should prepare by studying the exam content areas, reviewing the approved references, practicing book navigation, and building familiarity with plumbing code requirements, fuel gas provisions, mechanical system topics, sprinkler systems, wastewater rules, solar-related piping, and construction safety.

The contractor application process may include business information, qualifying party information, documentation, and other licensing materials required for the Arizona contractor license application. This Ultimate package includes Application Service support to help candidates stay organized while working through the licensing process.

Application Service is included because exam preparation and licensing paperwork are both important parts of the contractor licensing goal. Passing the exam is a major step, but the application must also be completed properly. Organized application support helps candidates focus on study while keeping the licensing process moving forward.

State Requirements

The Arizona CR-77 Plumbing, Including Solar residential/commercial classification allows the scopes of work permitted by the commercial C-77 Plumbing, Including Solar license and the residential R-37 Plumbing, Including Solar license. This makes CR-77 a dual classification for contractors preparing to perform plumbing work in residential and commercial settings within the permitted scope.

The classification is tied to plumbing work, including solar-related plumbing systems. Residential and commercial plumbing work may involve water supply systems, drainage systems, venting, fixtures, traps, cleanouts, fuel gas piping, appliance connections, water heaters, sprinkler-related systems, wastewater-related provisions, solar system piping, testing, inspections, and code compliance.

State requirements matter because they define the type of contracting work that may be performed under the license. Candidates should prepare for the required examination, use the correct classification, and complete the application process carefully. This package supports both the study side and the application side by combining approved books, course access, highlighted and tabbed references, and Application Service.

Plumbing contracting requires attention to safety, sanitation, system performance, water distribution, drainage, venting, fuel gas safety, mechanical coordination, sprinkler provisions, wastewater requirements, solar piping, code compliance, inspections, and customer protection. The CR-77 exam path is designed to test knowledge connected to these responsibilities and the references used in the trade.

Candidates should prepare with the full dual scope in mind. Residential and commercial plumbing systems share many principles, but they may involve different system sizes, equipment, occupancy concerns, sprinkler requirements, wastewater considerations, inspection expectations, and code applications. A complete preparation plan should include trade review, code review, reference-book use, exam timing practice, and application organization.
