sunMAX - Pre-Install: Permit On-Site Checklist

When going on-site in preparation for the install, to limit the need to obtain additional information we have prepared a checklist for every field required by the Permit Application in the sunMAX Permitting tool.

Note: The following checklist is in addition to any local/state permit requirements—consult your local AHJ for more details & include these requirements in your permitting package submission. In cases where a Structural Engineer is required to sign off on building permits, you should partner up and source / contract locally to visit the site.
