For your information,

The B.C. Building Code is being updated to B.C. Building Code 2018 on December 10th, 2018 so every building permit from December 10th, 2018  onward has to comply to 2018 Building Code. Any building permit submission to December 9th can comply to B.C. Building Code 2012. You can get some idea on Code Changes at https://www2.gov.bc.ca/gov/content/industry/construction-industry/building-codes-standards/the-codes/2018-bc-codes-33901/code-changes.

Please note the more energy efficiency standards for buildings and plumbing.

Plan your Building Schedule accordingly.

B.C. Housing has on their website some Frequently Asked Questions which may help in your planning.
