Attention Electricians, Building Officials, and Contractors

The Department of Safety and Professional Services - Division of Industry Services wishes to update you on the status of the SPS 316 Electrical Code Package (CR 16-093). The proposed code package has been adopted and published. The new SPS 316 can be viewed here:

Here is a timeline of effective dates related to several parts of the code update:

  • August 1, 2018: 2017 NEC adopted for commercial structures.
  • August 1, 2018: DSPS can begin accepting applications for registration as an electrical inspection agency.
  • March 1, 2019: Only registered inspection agencies may provide plan review, permit issuance, or inspections.
  • January 1, 2020: 2017 NEC adopted for one- and two-family dwellings. “One− and two− family dwellings” means any buildings that contain one or two dwelling units the construction of which commenced on or after December 1, 1978, per SPS 316.006(7). Effective August 1, 2018, the 2017 NEC will apply to any building that does not meet the definition of “one and two- family dwellings”.
  • January 1, 2020: Statewide requirements for Commercial Electrical Permits and Inspections go into effect.

Important Note for Municipalities: Municipalities may exercise jurisdiction over the inspection of electrical wiring installations at farms, public buildings, places of employment, campgrounds, manufactured home communities, public marinas, piers, docks, or wharves and recreational vehicle parks provided the municipality complies with all of the following listed in SPS 316.011(1). Any municipality that wishes to exercise jurisdiction over the inspection of electrical wiring installations as described in SPS 316.011(1)(a) must register with the Department as an electrical inspection agency even if they are currently exercising jurisdiction as allowed under Subchapter V of SPS 316. In municipalities not exercising jurisdiction under SPS 316.011(1), the department shall provide permit and inspection services for the installation of electrical wiring on farms and in public buildings, places of employment, campgrounds, manufactured home communities, public marinas, piers, docks, or wharves and recreational vehicle parks.
