Project Information Contact information
Plan 2385
This set of forms has been developed to assist permit applicants documenting compliance with the
Washington State Energy Code, (2009 edition). This set is for structures built under the IRC and located
in Climate Zone 1.
The following forms provide much of the required documentation for plan review. The details noted here
must also be shown on the drawings (WSEC 104.2).
This form is not a substitute for the energy code itself. To obtain a copy of the energy code,
