Ontario farmers need a building permit for most agricultural construction projects. Agricultural steel buildings offer the strength and flexibility that modern farming demands. From livestock barns to equipment storage facilities, steel construction delivers lasting value for agricultural properties across the province. Ruthven Greenhouse Construction, are the local greenhouse construction experts with over 25 years of experience, helps farmers design and build pre-engineered steel buildings that meet Ontario building requirements and serve their operations for decades.
Why Ontario Farmers Choose Steel Buildings
Pre-engineered steel buildings have become the preferred choice for agricultural construction across Ontario. These structures deliver significant advantages over traditional wood or brick buildings. Steel frames resist fire, pests, and rot while requiring minimal maintenance over their lifespan. The non-combustible nature of steel provides added safety for operations storing hay, feed, or equipment with fuel.
The pre-fabricated nature of steel building components reduces construction time and on-site waste. Manufacturers cut steel members to exact specifications at the factory, eliminating the material waste common with conventional construction methods. This precision also lowers labor costs since crews spend less time measuring, cutting, and fitting components on site.
Steel buildings provide large, unobstructed interior spaces that accommodate modern farming equipment. Clear-span designs eliminate interior columns that restrict movement and limit how farmers can use their space. Wide door openings allow combines, tractors, and other large machinery to enter and exit without difficulty. Farmers can reconfigure interior layouts as their operations evolve without major structural modifications.
Common Agricultural Applications
Steel structures serve many purposes on Ontario farms. The versatility of pre-engineered designs means farmers can customize buildings for their specific needs. The intended use of a building determines which code requirements apply to your project.
Livestock Housing: Steel barns provide secure, easy-to-clean environments for cattle, hogs, poultry, and other animals. Proper ventilation systems maintain air quality while insulation options keep animals comfortable through Ontario’s temperature extremes.
Equipment Storage: Farm machinery represents a significant investment that deserves protection from weather and theft. Steel buildings shelter tractors, implements, and vehicles from rain, snow, and sun damage.
Feed and Grain Storage: Properly designed steel structures keep feed dry and protected from pests. Climate control options help maintain optimal storage conditions for grain and other harvested crops.
Produce Storage and Packing Houses: Post-harvest handling requires clean, temperature-controlled environments. Steel buildings accommodate refrigeration systems and provide the sanitary conditions produce storage demands.

Ontario Building Code Requirements
The Building Code Act establishes the legal framework for construction in Ontario. Under this legislation, farmers must obtain a permit to construct structures exceeding 10 square metres (108 square feet) in building area. This requirement applies to new construction, additions, and major renovations.
The requirements for farm buildings differ from commercial or residential structures. The Building Code defines a farm building as a structure that does not contain residential space, sits on land used for farming, and serves the housing of equipment or livestock or the production, storage or processing of agricultural produce or feeds. Buildings meeting this definition may qualify for certain code relaxations under the National Farm Building Code of Canada.
Design and Professional Requirements
Designer qualifications depend on building size and complexity. Farm buildings under 600 square metres and three storeys or less can be designed without professional credentials if they follow Supplementary Standard SB-11. Larger structures require designs prepared by an architect or a professional engineer. Regardless of size, the building must meet all structural and safety standards.
When you change the use of an existing structure, additional reviews apply. A change of use from storage to livestock housing, for example, triggers new code requirements. If you plan to change the use of a building from one classification to another, confirm what approvals you need before starting work.
Ruthven Greenhouse Construction works with qualified engineers to ensure the building being constructed meets all Ontario Building Code requirements. Our team coordinates the design and permit process so farmers can focus on their operations.
Site Planning and Approvals
Before construction begins, farmers must address several site-related requirements. Proper planning prevents delays and helps ensure the building serves its intended purpose effectively. Contact Ontario One Call before any site excavation is started to locate underground utilities and prevent service disruptions.
Minimum Distance Separation
Minimum distance separation formulas calculate required setbacks between livestock facilities and surrounding dwellings. These calculations function as a land use planning tool that protects both agricultural operations and residential neighbours. Your local building department can explain how these requirements affect your site layout options.
Conservation Authority Review
Properties near watercourses, wetlands, or flood plains may require approval before a building permit can be issued. Contact your local conservation authority to determine if your property includes regulated areas. Conservation authorities work alongside the Ministry of the Environment, Conservation and Parks to protect water quality and natural habitats. These agencies safeguard health and the environment while supporting responsible agricultural development.
Nutrient Management Requirements
The Nutrient Management Act establishes rules for farms with livestock operations. Farms generating more than five nutrient units that plan to build livestock housing or liquid manure storage facilities need an approved Nutrient Management Strategy. A site characterization study is required before constructing permanent liquid manure storage structures.
The municipality will require the Record of Approval before a building permit is issued. Operations planning liquid manure storage should begin this approval process early since it can take several months. Approval from the ministry confirms your nutrient management strategy meets provincial standards.
Source water protection requirements may also apply to your project. The Ministry of Agriculture, Food and Rural Affairs provides guidance on how these regulations affect agricultural operations.
The Building Permit Process
To get a permit for your agricultural steel building, follow these steps. Starting early and submitting complete applications helps avoid delays.
- Contact your local building department to discuss your project and confirm requirements
- Engage a qualified designer to prepare drawings that meet Ontario Building Code standards
- Complete minimum distance separation calculations if your building will house livestock
- Obtain approval from the Ministry of the Environment, Conservation and Parks if your site includes regulated areas
- Secure your Nutrient Management Act Record of Approval if applicable
- Submit your complete permit to construct application with all required documentation
- Pay applicable permit fees and await confirmation that your building permit can be approved
- Schedule required permit and inspection visits during construction
The Electrical Safety Code governs all electrical work in agricultural buildings. Electrical components mounted on a building require proper installation according to code standards. Signage mounted on a building and has a face area exceeding specific thresholds requires particular attention to electrical load calculations. Farmers must obtain separate electrical permits through the Electrical Safety Authority before starting electrical installation.
Cost Advantages of Steel Construction
Steel buildings often cost less than traditional construction when considering the complete project. While steel material costs may appear higher initially, several factors reduce overall project expenses and deliver better long-term value.
Faster construction timelines mean lower labor costs. Pre-engineered components arrive ready to assemble, reducing the skilled labor hours needed on site. Many steel building projects complete in weeks rather than the months required for conventional construction. This speed also means farmers can put their new facilities into service sooner.
Long-term operating costs favor steel construction as well. Steel structures resist fire better than wood buildings, which can reduce insurance premiums significantly. Reflective roofing options lower cooling costs during summer months. The durability of steel means fewer repairs and longer intervals between major maintenance projects.
