PERMITS
K103.1Types of permits.
An owner, authorized agent or contractor who desires to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure, or to erect, install, enlarge, alter, repair, remove, convert or replace electrical systems or equipment, the installation of which is regulated by this code, or to cause such work to be done, shall first make application to the building official and obtain the required permit for the work.

Exception: Where repair or replacement of electrical systems or equipment must be performed in an emergency situation, the permit application shall be submitted within the next working business day of the department of electrical inspection.

K103.2Work exempt from permit.
The following work shall be exempt from the requirement for a permit:

1. 1.Listed cord- and plug-connected temporary decorative lighting.
   
   
2. 2.Reinstallation of attachment plug receptacles, but not the outlets therefor.
