What Is the ICC F12-N Examination?

The F12-N examination is the ICC National Standard Building Contractor (B) examination. Participating jurisdictions may use it as part of a building contractor license, registration, certification, or qualification process.

Current examination information lists:

• 80 multiple-choice questions
• Four-hour time limit
• 70% passing requirement
• Open-book format

The exam requires candidates to identify the construction issue, select the correct reference, locate the controlling requirement, and apply it to the facts presented.

Passing F12-N does not automatically grant a contractor license. The applicable jurisdiction controls experience, insurance, financial qualifications, business registration, applications, fees, background requirements, and final approval.

F12-N Listed References

The current preparation package identifies the following references:

• International Building Code, 2015 Edition
• International Residential Code for One- and Two-Family Dwellings, 2015 Edition
• ICC Concrete Manual, 2021 Edition

The International Building Code supports preparation involving commercial and multifamily construction, occupancy, construction types, height and area, fire resistance, egress, accessibility, structural provisions, inspections, exterior walls, roofing, and special construction.

The International Residential Code supports preparation involving one- and two-family dwellings and qualifying townhouses, including foundations, floors, walls, roofs, stairs, guards, emergency escape openings, exterior coverings, and residential structural tables.

The ICC Concrete Manual supports preparation involving concrete materials, reinforcement, formwork, placement, consolidation, curing, inspection, testing, and structural concrete principles.

Candidates should verify the exact references and editions shown for their examination registration before purchasing books or scheduling the test.

How the F12-N References Work Together

• Use the International Building Code for general commercial construction, occupancy, fire and life safety, accessibility, structural systems, materials, inspections, and building-envelope requirements.
• Use the International Residential Code for qualifying residential buildings and detailed residential framing, foundation, stair, roofing, and wall requirements.
• Use the ICC Concrete Manual for concrete construction practices, reinforcement, placement, formwork, curing, testing, and inspection concepts.

Choosing the correct reference before searching for an answer is one of the most important skills for this examination.

F12-N Content Outline

The current examination outline organizes the test into four broad areas:

• Permits and General Regulations: 21%
• Building Planning and Life Safety: 30%
• Structural Systems: 42%
• Building Envelope: 8%

Structural systems represent the largest portion of the examination. Candidates should devote significant study time to foundations, concrete, masonry, steel, wood framing, structural connections, roof systems, and load paths.

Confirm Local Building Contractor Requirements

Before purchasing materials or scheduling the examination, candidates should verify:

• Whether the licensing authority accepts F12-N
• The permitted scope of a Building Contractor (B)
• The required code year
• The current listed references
• The question count and testing time
• The required passing score
• Rules for tabs, highlighting, and notes
• Required construction experience
• Application and examination fees
• Insurance and bonding requirements
• Financial or business qualifications
• Renewal and continuing-education requirements

What Does a Building Contractor (B) Do?

A Building Contractor (B) may construct, remodel, repair, supervise, or manage building projects within the scope established by the applicable licensing authority.

Common responsibilities may include:

• Reviewing plans and specifications
• Coordinating permits and inspections
• Managing commercial and residential construction
• Supervising employees and subcontractors
• Coordinating foundations and structural systems
• Reviewing fire and life-safety requirements
• Managing accessibility and means-of-egress compliance
• Coordinating roofing and exterior-wall systems

• Maintaining safe and code-compliant jobsites

The exact classification scope varies by jurisdiction and may limit building height, occupancy, project type, structural work, or contract value.

Permits and General Regulations

Building contractors should understand how projects move through applications, plan review, permitting, inspection, correction, and final approval.

Study subjects may include:

• Work requiring permits
• Permit exemptions
• Construction documents
• Required inspections
• Alternative materials and methods
• Referenced standards
• Unsafe structures
• Stop-work orders
• Notices of violation
• Permit-holder responsibilities

Candidates should also understand that local administrative rules may be more specific than the national code provisions tested on F12-N.

Construction Documents and Plan Reading

F12-N candidates should be able to interpret architectural and structural information shown on construction documents.

Plan-reading subjects may include:

• Site plans
• Foundation plans
• Floor and framing plans
• Roof plans
• Building elevations
• Wall sections
• Structural details
• Door and window schedules
• Life-safety plans
• Plan symbols and abbreviations

Questions may require candidates to combine information shown on the plans with provisions found in one or more references.

Occupancy Classification

Occupancy classification describes how a building or space is used and affects many other code requirements.

Candidates should study:

• Assembly occupancies
