1. A farm

2. A public building, structure, or premises

3. A place of employment

Where Can I Get a Permit?

If the municipality covering your project location has been delegated authority to issue permits, and the project is not for a state-owned building or land, contact the municipality directly.

Use the Electrical Delegated Agent List to determine if your municipality has authority to permit and inspect your project.

If your municipality does not have the proper authority, submit your application to DSPS via esla.wi.gov. See the eSLA Customer Information page for getting started in eSLA.

Inspection

Commercial electrical wiring requires inspections. Note that wiring shall remain accessible and exposed for inspection purposes, and wiring shall not be energized prior to inspection.

When ready for inspection, notify the inspector identified on your commercial electrical permit.

Plan Review

Electrical plan reviews are not required. However, you may choose to submit electrical plans to DSPS for review via esla.wi.gov. Plan review fees will apply. 

COMcheck

COMcheck is a Federal Department of Energy (DOE) software approved in Wisconsin for demonstrating compliance with commercial building envelope requirements and interior and exterior general lighting requirements ONLY (HVAC portions of the program are not acceptable). COMcheck can be used for commercial buildings or high-rise (>3 stories) multi-family buildings. Within COMcheck, a user is required to choose the code option of "2021 IECC" unless 2021 IECC section C401.2.2 is applied which would then allow the application of ASHRAE 90.1-2019, in which case the option "90.1 (2019) Standard" must be used.
