Determining local code is difficult because there is the overarching International Residential Code (IRC) that acts as a baseline for proper building code requirements, but there are also local building codes that may differ from the national requirements.
Interpreting code is not always straightforward either.

Talk about an uphill battle!
So, in this post we’ve at least centralized the code requirements, and we’ve also provided a few additional best practices we thought might make your project research a little easier. Of course, we have to disclaim that it is always prudent to check with your local regulatory department before proceeding with your project, just to make sure you are in compliance with all the unique code requirements of your area.
