Seattle’s refrigeration regulations are part of the Seattle Mechanical Code.
This is a read-only version of the 2012 Seattle Mechanical Code. You can buy a full version from iccsafe.org.
As of January 1, 2017, you must design your Seattle projects using the 2015 Seattle Mechanical Code. We will have electronic and print copies of the 2015 code available soon. We will post the electronic version on this website as soon as it's available. Print versions will be available through our Public Resource Center.
