Permitting Tool Kit — One- and Two-Family
Residential ESS
The following documents form an optional tool kit that AHJs can use to ensure a predictable and efficient
process for permit applicants. The templates can be adopted with minor administrative adjustments by a
jurisdiction, as needed. Building officials should review the template documents and their assumptions and
make further modifications as necessary to meet the needs of their jurisdiction.
