NOTE: Code References are to the 2024 Edition of the BC Building Code. While every effort has been made to ensure accuracy, it is the responsibility of the user to confirm all references and calculations are correct before using any data, calculations, or references in real life application. BCABD cannot be held responsible for any errors or omissions while this tool and information is used. All users should do their own due diligence to ensure spatial separations and all code requirements are being met for their own projects. This calculator is provided as tools to help determine the allowable area of unprotected openings according to the BC Building Code Requirements in 9.10.14. and 9.10.15. Please note that the BC Building Code does not give explicit permission to use interpolations of the tables to determine permitted unprotected openings. The final decision as to whether interpolations are permitted rests with the Authority Having Jurisdiction (AHJ). It is recommended that you consult the AHJ to confirm whether or not interpolations of the tables are acceptable.
