2012 OBC • CodeNews Issue 210 ‐ The New 2012 Building Code • Ontario has released a new Building Code. • On November 2, 2012, Ontario Regulation 332/12 was filed / to introduce the new Building Code. Most of the new Building Code will come into force on Jan 1 • Most of the new Building Code will come into force on Jan. 1, 2014. However, certain requirements will come into force later on Jan. 1, 2015 and Jan. 1, 2017. • The new Building Code substantially improves energy‐ Th B ildi C d b t ti ll i efficiency requirements and makes Ontario one of the leading jurisdictions in North America for water conservation. • Ontario Regulation 332/12 is available on Service Ontario’s e‐ Laws website.
