Summary Table of Key Details

AspectDetails
DefinitionConstruction with non-combustible exterior walls and a fire-rated internal framework.
Primary MaterialsMasonry, steel, and fire-treated wood.
Fire Resistance RatingTypically 1 hour for structures (varies by local codes).
Common ApplicationsResidential apartments, small retail buildings, mixed-use properties.

What Exactly is Construction Type 3A?

Construction Type 3A, also known as Protected Combustible, is a classification defined by the International Building Code (IBC). It mandates that the building’s exterior walls must be made of non-combustible materials, such as concrete or masonry, while the internal structural elements, like beams and trusses, can utilize treated wood or steel – as long as they meet stringent fire resistance standards.

The Key Features of Type 3A Buildings

  • Non-combustible Exterior Walls

Made from fire-resistant materials like brick or reinforced concrete, these walls are designed to limit the spread of fire beyond external boundaries.

  • Protected Structural Elements

Internal components such as floors, roof assemblies, and framing must be treated or built to resist fire for at least one hour.

  • Flexibility in Design

This classification supports a balance between cost-efficiency and safety, making it ideal for mixed-use properties or smaller commercial spaces.

Why Does Arizona Use Type 3A?

Arizona’s dry climate and potential for wildfires necessitate strict building codes. Type 3A is favored for preventing fire spread, protecting property, and ensuring occupant safety—especially in urban and residential areas where density increases risks.
