What is a Building Code?
A building code is a set of minimum construction and safety standards set by government authorities that all buildings must meet to ensure health, safety, and accessibility.
Why Do Building Codes Matter in Real Estate?
In Canadian real estate, the National Building Code and provincial codes regulate everything from structural integrity to fire protection and energy efficiency.
Key areas covered by building codes include:
- Electrical and plumbing systems
- Fire exits and safety equipment
- Structural load and material standards
- Accessibility and insulation requirements
Builders must obtain permits and pass inspections to confirm code compliance. Renovations and new constructions that violate code can face fines, delays, or demolition orders.
Example of a Building Code in Action
A builder modifies the stair width to meet building code requirements after a municipal inspector flags it as non-compliant.
