The 1 Package: All-Inclusive Arizona General Dual Residential / Commercial Contractor (KB-1) Exam, Licensing & Business Setup Solution

Prepare for the Arizona General Dual Residential / Commercial Contractor KB-1 exam while building the licensing and business foundation needed to operate professionally. The 1 Package combines contractor exam preparation, reference books, application assistance, business formation, EIN filing, and contractor compliance guidance in one organized solution.

This all-inclusive Arizona KB-1 contractor package is designed for experienced general contractors, construction supervisors, project managers, qualifying parties, and business owners pursuing authority to perform both residential and commercial building work in Arizona.

Instead of purchasing books, finding an exam-preparation course, organizing licensing documents, and establishing a construction business through separate providers, customers receive coordinated support through one comprehensive package. The program connects exam preparation with the application and business setup services needed to pursue an Arizona dual building contractor license.

The preparation program addresses sitework, concrete, masonry, structural metals, carpentry, thermal and moisture protection, doors and windows, finishes, construction safety, residential building codes, and commercial building codes. Candidates can strengthen their construction knowledge while developing the reference-navigation skills needed for the open-book portion of the examination.

The KB-1 exam covers a broad range of building disciplines. Candidates may need to interpret code provisions, understand construction methods, evaluate jobsite safety conditions, identify appropriate materials, and apply trade knowledge to residential or commercial building situations. A structured preparation plan helps divide this large subject area into manageable study sections.

The package includes 1 year of course access, giving candidates time to prepare around work, project, and family responsibilities. The course supports trade-focused review, practice-oriented preparation, code navigation, and confidence-building study.

The 1 Package also supports the licensing and business stages that follow examination preparation. Application Service helps organize the Arizona contractor licensing process. Business Formation establishes an LLC or corporation, EIN Filing supports banking and tax administration, and Contractor Compliance Guidance helps customers understand responsibilities associated with operating an Arizona dual residential and commercial contracting business.

Exam Details

The Arizona Registrar of Contractors licenses and regulates residential, commercial, and dual contractors in Arizona. PSI administers the trade examination associated with the KB-1 Dual Building Contractor classification.

The KB-1 classification combines residential and commercial general building authority within the scope established by the Arizona Registrar of Contractors. It is intended for contractors responsible for coordinating and performing building projects that involve multiple construction trades.

The qualifying party is the individual whose experience and examination qualifications support the contractor license. This person must satisfy the applicable Arizona requirements and remain associated with the licensed business in the capacity recognized by the state.

The Arizona general building trade examination used for the KB-1 classification contains 100 questions. Candidates are allowed 240 minutes and must earn a minimum passing score of 70 percent.

The examination content includes sitework, concrete, masonry, metals, carpentry, thermal and moisture protection, doors and windows, finishes, safety, and general building-code requirements. The test may include questions based on the listed references, practical trade knowledge, and general construction practices.

Sitework preparation may involve excavation, grading, trenching, soils, utilities, drainage, foundations, layout, and safe earth-moving practices. Concrete study may include materials, proportioning, placement, reinforcement, finishing, curing, formwork, and quality control.

Masonry preparation may address brick, block, stone, mortar, grout, reinforcement, flashing, walls, openings, and construction procedures. Metals study may involve structural steel, joists, decking, connections, erection, welding concepts, and jobsite safety.

Carpentry preparation may include framing, floors, walls, roofs, stairs, doors, windows, interior construction, materials, layout, and construction methods. Thermal and moisture protection may include roofing, flashing, insulation, waterproofing, sealants, vapor control, and weather-resistant construction.

The examination also addresses general residential and commercial building-code requirements. Candidates should understand how to use the 2018 International Residential Code and 2018 International Building Code to research occupancy, construction, structural, fire-safety, egress, accessibility, and building-system requirements.

Applicants for the KB-1 classification may also use the NASCLA Accredited Examination for Commercial General Building Contractors in place of the Arizona ROC trade examination. Candidates choosing the Arizona examination should prepare according to the Arizona PSI content outline and reference instructions.

Open Book Test

The Arizona KB-1 trade examination is an open-book test with restrictions. Candidates may use only the references identified by PSI as permitted in the examination center. Other included books serve as supplemental study resources and cannot automatically be taken into the testing room.

The exam allows 240 minutes for 100 questions. Candidates have an average of approximately two minutes and twenty-four seconds per question, making efficient reference navigation essential. Searching every book from the beginning for each answer can consume too much time.

The approved references may be highlighted, underlined, annotated, and indexed before the examination. Permanent tabs are permitted. Temporary tabs, removable notes, loose papers, and unauthorized attached pages are not allowed.

Candidates may not write, highlight, underline, or add indexing during the examination session. All materials remain subject to inspection by testing personnel before the test begins.

A silent, nonprinting, nonprogrammable calculator may be used in the examination center. Candidates should practice calculations using a basic calculator rather than relying on functions that may not be available on exam day.

All books are highlighted and Tabbed. Regular practice with the prepared references helps candidates become familiar with code organization, chapter locations, safety provisions, tables, diagrams, and permanent tab placement.

Licensing Steps

1. Confirm the KB-1 classification. Review the dual residential and commercial building scope and make sure it matches the work the business intends to offer.
2. Select the qualifying party. Identify the individual who will satisfy the applicable experience and examination requirements.
3. Choose the examination path. Determine whether the qualifying party will take the Arizona ROC trade exam or use the accepted NASCLA commercial general building examination route.
4. Prepare for the trade examination. Use the included course, approved references, supplemental books, practice questions, and reference-navigation exercises.
5. Complete the required examination process. Pass the applicable trade examination and complete the Arizona Statutes and Rules requirement unless an authorized waiver applies.
6. Form the business entity. Use the included Business Formation service to establish an LLC or corporation for the contracting business.
7. Obtain an EIN. Complete the included EIN Filing with the IRS for banking, taxation, payroll, hiring, and professional business operations.
8. Complete applicable background requirements. Follow the Arizona process for individuals required to be listed on the contractor application.
9. Prepare the license application. Organize qualifying-party information, experience documentation, examination results, business records, and required disclosures.
10. Obtain the required contractor bond. Arrange the dual-license bond based on the residential and commercial requirements applicable to the anticipated volume of work.
11. Address residential financial protection. Complete the applicable Residential Contractors’ Recovery Fund requirement or authorized alternative.
12. Submit the application. Provide the completed application and supporting documentation to the Arizona Registrar of Contractors.
13. Wait for license issuance. Do not offer or perform work requiring the KB-1 license until the state approves the application and issues an active contractor license.

State Requirements

The KB-1 license is a dual building classification covering residential and commercial general contracting within the scope established by the Arizona Registrar of Contractors. Dual classifications combine authority that would otherwise require separate residential and commercial licenses.

The proposed qualifying party must demonstrate the required experience, knowledge, and skills. Experience documentation may need to describe project supervision, construction methods, trade coordination, structural work, building systems, and the length of relevant construction experience.

The legal entity applying for the contractor license must be properly established. The company name, ownership records, qualifying-party information, EIN documents, contractor bond, and licensing application should remain consistent throughout the process.

Arizona contractor applicants must complete applicable background-check requirements and submit the identification, business, examination, experience, and disclosure information required for state review.

A contractor license bond is required. Because KB-1 is a dual classification, the bond amount is calculated by combining the applicable residential and commercial bond requirements. The required amount depends on the anticipated gross volume of work.

The residential portion of the dual license is also subject to Arizona’s residential financial-protection requirements. Applicants must participate in the Residential Contractors’ Recovery Fund or provide an authorized alternative when applicable.

Passing the trade examination is one part of the licensing process. It does not authorize a person or company to advertise, bid, contract, or perform work requiring an active Arizona contractor license.

After licensing, the contractor must work within the authorized KB-1 scope, maintain the required bond, renew the license, and keep business and qualifying-party records current. Changes involving ownership, legal structure, address, bond, or qualifying party may require additional filings.

The course divides the broad general building examination into manageable subjects, including sitework, concrete, masonry, metals, carpentry, roofing, finishes, safety, residential codes, and commercial building codes.

Practice-oriented preparation helps candidates apply construction knowledge instead of relying only on reading. Reference-navigation exercises help students identify the correct approved book, select useful search terms, locate the controlling provision, and confirm answers efficiently.

The highlighted and tabbed books support faster navigation, but regular practice remains important. Repeated use helps candidates become familiar with code organization, safety provisions, tables, diagrams, and major construction subjects.

Application Service supports the licensing stage by helping organize business information, qualifying-party records, examination documentation, and other application materials. Business Formation establishes an LLC or corporation so the customer has a legally structured business entity.

EIN Filing with the IRS provides the federal identification number used to open business bank accounts, manage taxes properly, hire employees, and operate professionally. Contractor Compliance Guidance supports a clearer understanding of responsibilities associated with maintaining an Arizona contracting business.

No preparation program or business service can guarantee an examination result, licensing approval, earnings, or business success.
