During the examination session, candidates may not write, highlight, underline, or index in the references.

Permanent tabs are allowed. Temporary tabs, including Post-it style tabs or other removable tabs that can be removed without tearing the page, are not allowed and must be removed before the exam begins. Candidates may not bring additional papers, whether loose or attached, with the approved references.

Downloaded reference materials may be brought into the testing center when properly bound. Spiral binding or a hole-punched binder format may be used when permitted by testing rules. Book preparation should be completed before the exam appointment so the candidate can focus on answering questions instead of correcting reference problems at the testing center.

Open-book preparation should include regular practice with tables of contents, indexes, definitions, chapter headings, code tables, sizing tables, sprinkler standard sections, wastewater provisions, and OSHA safety standards. With eight references in this package, candidates should practice choosing the correct book quickly before searching for an answer. A clean permanent tabbing system and repeated timed lookup practice can help improve pacing during the exam.

Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. Candidates pursuing the Arizona CR-77 Plumbing, Including Solar Residential / Commercial Contractor license should begin by confirming that this classification matches the plumbing and solar-related plumbing work they plan to advertise, contract for, supervise, and perform.

The qualifying party is the person who qualifies the license by meeting the knowledge, experience, and examination requirements for the classification. For many applicants, the qualifying party must complete the required trade exam and the Arizona Statutes and Rules requirement unless an approved waiver applies.

Common licensing steps include selecting the correct license classification, identifying the qualifying party, completing the required examination or approved waiver process, meeting the Arizona Statutes and Rules requirement when required, forming or registering the business entity when applicable, obtaining the required bond, completing background checks for required individuals, providing government-issued identification, and submitting the completed license application with required documents and fees.

Applicants using an LLC or corporation should make sure the business entity is properly formed or registered before submitting the contractor license application. The legal business name should match across entity records, bond documents, application paperwork, and future advertising. Consistent documentation helps reduce delays during application review.

Passing the trade exam is an important step, but it does not automatically issue the contractor license. Applicants must complete the full Arizona Registrar of Contractors application process and meet all licensing requirements for the classification. Candidates should prepare for the exam while also staying organized with business records, bond information, background checks, identification, and application paperwork.

State Requirements

The Arizona CR-77 Plumbing, Including Solar classification allows the licensee to install, alter, and repair all plumbing, including solar, when performed solely within property lines and not on public easements or rights-of-way except as allowed by the classification. The scope includes installation, alteration, and repair of piping, fixtures, and appliances related to water supply, including pressure vessels and water heaters.

The classification also includes installation, alteration, and repair of sanitary drainage and vent systems, storm drainage systems, fuel gas piping, water conditioning equipment, solar water heating systems, and related equipment within the scope of plumbing work. Candidates should understand how plumbing, solar, fuel gas, mechanical, sprinkler, and wastewater references may connect to residential and commercial projects.

Because CR-77 is a residential/commercial contractor classification, it is intended for plumbing, including solar, work in both residential and commercial settings within the limits of the classification. Arizona also issues separate commercial-only and residential-only classifications for certain trades. Contractors should select the license classification that matches the work they intend to perform.

Some plumbing and solar-related projects may require coordination with other properly licensed contractors when work involves electrical systems, structural work, mechanical systems beyond the plumbing scope, fire protection systems, excavation, utility work, or other specialty work outside the CR-77 classification. Understanding license scope helps contractors stay aligned with Arizona licensing requirements.

Arizona contractor applicants should also prepare for requirements related to the qualifying party, examination completion, Arizona Statutes and Rules requirements, background checks, bonding, business formation or registration when applicable, identification, application forms, and fees. The Arizona Registrar of Contractors reviews the completed application before issuing the license.

Test Information and Study Materials

The Arizona CR-77 exam covers plumbing, solar-related plumbing, fuel gas systems, mechanical coordination, sprinkler references, on-site wastewater provisions, construction safety, and practical trade knowledge. A strong study plan should follow the exam content and give attention to each major reference. Candidates should avoid relying only on field experience or only on book lookup. The exam may require both.

For plumbing code, candidates should work directly with the 2018 International Plumbing Code. Study should include fixtures, fixture counts, water distribution, sanitary drainage, vent systems, traps, cleanouts, interceptors, storm drainage, backflow protection, pipe materials, joints, supports, testing, and installation requirements.

For solar-related plumbing, candidates should review solar water heating system concepts, storage tanks, heat transfer, piping, valves, pressure relief, temperature control, backflow protection, equipment connections, system isolation, freeze protection concepts, and safe installation practices.

For fuel gas, candidates should review the 2018 International Fuel Gas Code. Important topics include gas piping materials, pipe sizing concepts, appliance connections, shutoff valves, pressure testing, combustion air, venting, gas-fired water heaters, and fuel gas safety requirements.

For mechanical coordination, candidates should study the 2018 International Mechanical Code. Plumbing, solar, and fuel gas systems may intersect with mechanical equipment, ventilation, combustion air, exhaust systems, appliances, and access requirements. Understanding how these systems relate can help candidates approach code questions more efficiently.

For sprinkler system references, candidates should become familiar with NFPA 13, NFPA 13D, and NFPA 13R. These references are detailed standards, so candidates should practice navigating chapter headings, tables, definitions, system types, installation provisions, and component requirements.

For on-site wastewater, candidates should study the Arizona wastewater treatment facility provisions listed for the exam. Preparation should include wastewater terminology, system components, treatment concepts, site considerations, regulatory language, and the structure of the Arizona Administrative Code reference.

For jobsite safety, candidates should work directly with OSHA 29 CFR Part 1926. Plumbing and solar-related work may involve trenching, excavation, ladders, roof access, tools, material handling, cutting equipment, personal protective equipment, hazard communication, and coordination with other trades. Safety preparation supports both exam readiness and responsible jobsite practice.
