Log home exemption from National building Code energy efficiency

Yukon adopted section 9.36 of the National Building Code in 2016, with some amendments that take Yukon’s climate, geography and construction types in account.

This standard ensures that a minimum efficiency level of 78/100 on the Energuide rating is met. As long as builders meet this rating they can:

  • reduce the minimum insulation requirement in their ceilings from R60 to R40; and
  • remove the insulation requirement in crawl space floors.

Builders or designers looking to construct a residence 480 square feet or less are exempt from 9.36.

Builders or designers constructing log homes must meet a minimum thickness for exterior walls of log homes. Squared logs must be 8 inches thick and rounded logs must be a minimum of 10 inches in diameter. Log homes outside Whitehorse are exempt from section 9.36.

City of Whitehorse building standards are established by municipal bylaw and generally exceed the requirements of the National Building Code.
