The 2024 updates to the Ontario Building Code (OBC) are some of the most significant changes to building regulations in years, particularly for the warehouse industry. For warehouse managers, understanding these updates isn’t just about compliance—it’s about adapting to new standards that ensure safety, operational efficiency, and future-proofing infrastructure.
This blog breaks down the key changes in the 2024 Ontario Building Code for warehouses, explores how they affect construction and warehouse racking systems, and offers strategies to stay compliant.
Key Changes in the 2024 Ontario Building Code
The 2024 OBC integrates revised standards and modernized approaches to ensure structures can withstand various forces and conditions. Here are some of the most relevant updates for warehouse construction and operation:
Structural Load Regulations
One of the major revisions in this update involves structural load calculations. The code introduces new load factors and combinations to improve safety and durability. These include increased design loads to account for scenarios such as wind, snow, live loads, dead loads, and even seismic events.
Incorporation of AISI Standards
The 2024 OBC incorporates updates from the American Iron and Steel Institute (AISI), including the merging of AISI S201-12 with S200-12. These standards provide guidance for the design and installation of cold-formed steel structures, widely used in warehouses. This affects elements such as steel walls, mezzanines, and even components of racking systems.
Permit and Fire Safety Enforcement
The update expands previous permit requirements to include selective pallet racking systems and warehouse storage platforms. Detailed site plans, fire safety measures, and certified engineering documentation are now mandatory during the permit application process. This change emphasizes the importance of working with qualified professionals to design compliant systems.
Material Standards
The code emphasizes higher standards for structural materials. For all warehouses and racking systems, materials like concrete, steel, and fasteners now require documented proof of strength, durability, and adherence to AISI guidelines.
Structural Analysis and Detailing
Enhanced requirements for material testing and system detailing help ensure that no weak links exist in the structural design. Detailed drawings, stress analyses, and safety redundancies must now be incorporated into every build.
Racking System Integration
Racking systems must no longer be treated in isolation. The updated guidelines ensure storage racks are designed as integrated parts of the structure, creating alignment between floor loading, anchoring, and fire suppression systems.
Design Requirements for Special Structures
Facilities containing mezzanines, suspended platforms, or spiral conveyors face additional requirements for load-bearing capacity and seismic compliance.
| Structure | Design Requirement |
| Air-, Cable-, and Frame-Supported Membrane Structures | Air-, cable-, or frame-supported membrane structures must comply with CSA S367 standards. Designs should meet the 2024 OBC load requirements and follow limit states design principles. |
| Parking Structures | Parking garages and repair garages, along with their ramps and walkways, must meet the standards outlined in CSA S413, “Parking structures.” |
| Storage Racks | Storage racks and their anchorage shall be designed to withstand loads as per the 2024 OBC. |
| Guards Over Retaining Walls | Retaining walls covered under the 2024 OBC must have guards installed on all open sides if the public can access the top of the wall. |
| Anchor Systems on Building Exterior |

The Impact on Racking Systems
One of the most affected areas of the 2024 updates is racking systems. With evolving requirements, racking systems must adhere to stricter warehouse safety and performance measures, particularly in the areas of load capacity, seismic compliance, and fire protection.
Load Capacity
Design loads for racking systems have increased, making it imperative for warehouse managers to verify all storage racks meet these updated requirements. This involves assessing their existing racking systems to ensure proper stability under heavier loads and higher stress scenarios.
Seismic Design
Ontario may not often experience severe earthquakes, but seismic compliance is now mandatory. The OBC aligns with National Building Code recommendations in areas such as:
- Anchoring and Bracing: Racks must be securely anchored to withstand seismic forces.
- Dynamic Testing: Racking structures must pass analysis and testing to confirm their stability under seismic conditions.
Warehouse managers will need to consult with engineers specializing in seismic design to meet these requirements.
Fire Protection
Fire safety requirements are stricter than before. Key updates include:
- Fire Resistance Ratings: Racking systems must demonstrate the ability to prevent rapid flame spread.
- Sprinkler Systems: Clear guidelines must be followed to avoid obstructions and ensure fire suppression mechanisms work properly.
Compliance Strategies and Best Practices
Staying compliant with the 2024 OBC will require warehouse managers to adopt strategic processes and best practices. Proactively addressing these changes will mitigate risks, reduce regulatory challenges, and enhance workplace safety.
Early Engagement with Building Officials
Maintain open communication with building officials during the early planning stages of any construction or racking retrofit to clarify requirements and seek approvals.
Hiring Qualified Professionals
Collaborate with licensed structural, fire protection, and seismic engineers. Their expertise will help ensure your facility is compliant and structurally sound.
Staying Updated on Code Changes
Continuous learning is key. Attend workshops, subscribe to updates from the Ministry of Municipal Affairs and Housing, and regularly consult industry resources.
Adopting Advanced Design Tools and Software
Adopt design tools and software capable of incorporating updated OBC provisions. This will allow for streamlined design, precise analysis, and waste reduction.
Implementing Quality Control and Quality Assurance
Conduct rigorous inspections and audits during each phase of construction or racking installation to ensure compliance.
Benefits of Adopting the New Regulations
The new OBC guidelines pose challenges, but compliance offers substantial benefits. Warehouse owners who act now reap immediate and long-term rewards, including:
- Enhanced Safety: Protect workers and goods with stronger, more durable structures.
- Cost Savings: Prevent costly fines, delays, or rebuilds due to non-compliance.
- Sustainability: Meet modern efficiency and environmental standards, contributing to responsible resource management.
