What Is BCIN Certification in Ontario?
BCIN stands for Building Code Identification Number — a professional license issued by the Province of Ontario that qualifies individuals to design buildings and prepare building permit drawings. Understanding BCIN certification helps you choose the right professional for your project and ensures your permit application will be accepted.
Who Needs BCIN Certification?
In Ontario, anyone who designs buildings or prepares permit drawings for construction must hold a valid BCIN. This includes designers who prepare permit drawings for houses (Part 9 buildings), small buildings (Part 3), large buildings, HVAC systems, and plumbing systems.
BCIN Categories
BCIN certification is divided into categories based on building type and system: House (Part 9), Small Buildings (Part 3), Large Buildings (Part 3), HVAC, and Plumbing. Ontario Design Studio holds BCIN certification for residential and small building design. For larger or specialized projects, we coordinate with architects and professional engineers.
BCIN vs. Architect vs. Engineer
Architects and professional engineers can also prepare building permit drawings in Ontario. For most residential projects (Part 9 buildings under 600 m² and 3 storeys), a BCIN designer is the most cost-effective option. Larger projects may require an architect or engineer by law.
