Lumber continues to be a building material cost wildcard.  There is always a reason for this too, either government manipulation and tariffs, a recent favourite, or fires in B.C. 

Regardless of the reason, cost escalates randomly and often a lot   You do see occasional drops in prices for OSB, right now the sheet is down $2 from last year.  Structural components are up though, and by more than 30%.  This is really driving up the cost of my project so I’m frustrated.  We found a few savings in an earlier phase of work but it is all offset by the framing package.  

Here is a shot of some pricing last year and this year for the same product.
