Building Codes & Load Requirements by State

The basics

Why building codes matter for your steel building

Planning a steel building requires more than choosing the size and design of the structure. Every building must comply with construction regulations that ensure safety, structural performance, and long-term durability.

Building codes define the minimum requirements for structural design, materials, and safety systems used in construction. These regulations determine how a building must be engineered to withstand environmental forces, including wind, snow accumulation, seismic activity, and roof loads.

Understanding applicable building codes is essential before designing or purchasing a metal building. Local authorities review construction plans and issue permits to ensure structures comply with these regulations.


The national baseline

What building codes apply to metal buildings?

Most jurisdictions in the United States base their building regulations on the International Building Code (IBC) developed by the International Code Council. The IBC establishes structural design standards and references engineering guidelines, such as ASCE 7, which defines minimum structural load requirements, including wind, snow, seismic, and other environmental loads. Although the IBC provides a national model, individual states and municipalities adopt and modify these codes to address regional conditions.

Engineering fundamentals

Structural loads that drive your design

Before a steel building can be engineered, the structural loads for the project location must be determined. These loads represent the forces acting on the structure throughout its lifespan.

Dead Load

The permanent weight of the building structure itself, including framing, panels, and fixed components.

Live Load

Temporary loads such as maintenance workers, equipment, or movable objects.

Wind Load

Wind pressure acting on the building's walls and roof surfaces. Wind loads vary significantly depending on geographic location.

snow load

The accumulated snow weight that the roof must safely support in colder climates.

seismic load

Structural forces generated during earthquakes.

collateral load

Weight of permanent non-structural equipment such as HVAC systems, lighting, sprinklers, and insulation.


Before you build

How the building permit process works

In most jurisdictions, the construction of a building requires a building permit before work can begin. Permit requirements vary by municipality, but most projects require engineering documentation demonstrating compliance with applicable building codes.

Building Codes & Load Requirements by State
  • Submit a building permit application and applicable fees
  • Provide construction plans and supporting documentation
  • Plan review for building code compliance
  • Zoning and land-use compliance review
  • Revise plans if required by the reviewing authority
  • Building permit approval and issuance
