Arizona Plumbing, Including Solar Residential Contractor (R-37) Books Allowed into Exam Package

Prepare for the Arizona Plumbing, Including Solar Residential Contractor (R-37) examination with a complete package of the listed reference books allowed into the exam room. This package brings together the plumbing, fuel gas, mechanical, fire sprinkler, construction safety, and Arizona onsite wastewater publications associated with the open-book portion of the R-37 contractor examination.

The Arizona R-37 classification combines residential plumbing with applicable solar work. Candidates preparing for this exam may need to understand water and gas piping, drainage and vent systems, plumbing fixtures, mechanical installations, fire-protection systems, onsite wastewater treatment, excavation safety, and related residential trade practices.

An open-book examination requires more than having the correct books available.

This coordinated book package gives candidates the listed exam-room references in one convenient collection for study and testing.

The package is designed for experienced plumbers, qualifying parties, supervisors, contractors, solar professionals, and business owners pursuing the Arizona Plumbing, Including Solar Residential Contractor R-37 classification. It is also useful for candidates who already understand residential plumbing but need the specific code books and standards associated with the exam room.

Studying with the actual exam references can help candidates become familiar with tables of contents, indexes, definitions, code chapters, technical tables, exceptions, diagrams, and appendices. Regular navigation practice can improve the ability to move between the plumbing, fuel gas, mechanical, sprinkler, safety, and wastewater materials under timed conditions.

This product includes the books and publications listed on this page. It does not include an online course, rental service, refundable deposit, Application Service, book highlighting, or tabs unless those features are specifically added through another product package.

Exam Details

The Arizona Plumbing, Including Solar Residential Contractor R-37 examination evaluates knowledge associated with residential plumbing and applicable solar work. Candidates should be prepared to work with technical codes, installation standards, construction safety regulations, and Arizona-specific wastewater provisions.

The R-37 classification includes residential plumbing work involving water and gas piping systems, fixtures, vents, sewage treatment systems, fire-protection systems, and devices common to the plumbing industry. The classification also includes applicable solar work within its authorized residential scope.

Exam preparation may involve drainage, waste and vent systems, water distribution, plumbing fixtures, water heaters, fuel gas piping, mechanical equipment, residential fire sprinklers, onsite wastewater treatment, excavation, and construction safety.

Questions may require candidates to locate a code section, identify a permitted material, interpret a technical definition, use a sizing table, evaluate a piping arrangement, recognize a safety requirement, or determine which code or standard applies to a specific residential condition.

The included publications serve different purposes. The International Plumbing Code addresses core plumbing systems. The International Fuel Gas Code covers gas piping, appliances, combustion air, and venting. The International Mechanical Code addresses mechanical installations and related equipment.

The three NFPA standards address different sprinkler-system applications. OSHA regulations support construction-safety preparation, while the Arizona Administrative Code publication contains state-specific onsite wastewater provisions.

Candidates should practice recognizing the subject of a question before searching. Selecting the correct publication quickly can reduce unnecessary navigation and provide more time for reading, interpretation, and review.

Open Book Test

The Arizona R-37 trade examination is an open-book test. Candidates may use approved reference materials during the examination under the testing provider’s current rules.

Open book does not mean that every answer will be easy to locate. The examination library includes several detailed codes and standards, and searching without a clear strategy can consume valuable time. Candidates should become familiar with each book before exam day.

A practical reference-navigation method begins by identifying the subject. A question about sanitary drainage, water supply, plumbing fixtures, traps, or water heaters may require the International Plumbing Code. A question involving gas piping, appliance connections, regulators, combustion air, or venting may require the International Fuel Gas Code.

Mechanical equipment, ventilation, exhaust, and related system questions may lead to the International Mechanical Code. Fire sprinkler questions may require NFPA 13, NFPA 13D, or NFPA 13R depending on the building, occupancy, and system described.

Construction-safety and excavation questions may require 29 CFR Part 1926. Arizona-specific onsite wastewater questions may require the listed provisions from Title 18, Chapter 9 of the Arizona Administrative Code.

Candidates should practice using tables of contents, indexes, definitions, chapter headings, technical tables, diagrams, cross-references, exceptions, and appendices. Reading the surrounding language is important because a nearby exception, note, or table heading may change how a provision applies.

Before reporting to the testing center, candidates should review the current examination bulletin for rules concerning permitted references, binding, tabs, highlights, handwritten notes, inserts, loose materials, and other book modifications.

Licensing Steps

Begin by confirming that the Arizona R-37 Plumbing, Including Solar residential classification matches the work the applicant or business plans to perform. Arizona maintains separate residential, commercial, and dual contractor classifications, so applicants should select the classification that corresponds with their intended scope.

Identify the qualifying party for the contractor license. The qualifying party is responsible for meeting the applicable experience, knowledge, and examination requirements associated with the requested classification.

Complete the required R-37 trade examination unless an authorized waiver applies. A separate Arizona statutes and rules requirement may also apply as part of the licensing process.

Complete the required background-check process and gather the documents associated with the applicant’s business structure. Contractor licenses may be issued to eligible business entities such as sole proprietorships, partnerships, limited liability companies, and corporations.

Obtain the required contractor bond and organize the supporting application materials. These may include identification, entity records, qualifying-party information, examination results, experience documentation, background-check records, bond documents, disclosures, and signed forms.

Because the R-37 classification includes solar work, applicants must also address the solar documentation required for the license application.

Submit the completed application to the Arizona Registrar of Contractors. Passing the trade examination is one part of the licensing process and does not automatically issue the contractor license. The applicant must satisfy the applicable state requirements and receive approval.

State Requirements

Arizona contractor licensing is administered by the Arizona Registrar of Contractors. Applicants must meet the requirements connected with the requested classification, qualifying party, relevant experience, examinations or approved waivers, background checks, contractor bonding, business documentation, and completed license application.

The R-37 classification applies to residential plumbing, including solar work, within the scope assigned to the classification. It should not automatically be treated as authorization for commercial plumbing or work outside the permitted residential scope.

The qualifying party should have experience relevant to the plumbing and solar work covered by the classification. Applicants should maintain clear records describing employment, projects, supervisory responsibilities, system installations, repairs, and hands-on trade experience.

Business names, ownership information, identification records, qualifying-party details, background-check materials, and bond documents should remain consistent throughout the application. Missing or conflicting information may delay the review process.

Applicants should use the current state forms and instructions when completing the licensing process. Examination procedures, application forms, and administrative requirements may be updated.
