Sanitees on back for DRY venting

You must purchase it, unless you can find a copy on the internet somewhere. The commentary includes the code. I was fortunate enough to find a 2009 IPC commentary several years ago on ebay for about $20. This worked for me as Pennsylvania stayed with the 2009 series for about 9 years while the majority of the country adopted the latest series.

You could try Amazon and other book websites for used copies.
