Question:
Hi Charlie, when a new version of NEC
® is adopted in a respective State, how is the implementation of the new Code applied? For instance, I am bidding a project and the electrical work will likely not start for 9-12 months. What happens if we bid it based on the 2020 NEC
® and our State adopts the 2023 NEC
® before we start work and there are major changes that impact cost? Thanks, Tom Leonardelli

Answer:
Hello Tom, great question. Unfortunately, there is not a “one size fits all” answer, as each State or jurisdiction may handle it differently.
One common practice is for a State or Jurisdiction to set an adoption/implementation date for the new edition of the NEC®, and any building permits obtained prior to the implementation date would still be held to the edition in place at the time of the issuance of said building permit. As always it is advisable to check with the local AHJ as they likely have an established process in place.
