    Strike-bold draft dated Aug 19, 2026, changes the edition from 2023 to 2026; advisory meeting set for Aug 27, 2026; not yet filed with the Secretary of State; effective 120 days after filing.

How Michigan adopts the NEC

  • Agency rule
  • The legislature reviews the rules and can block them
  • The legislature sets the update schedule

LARA drafts rules, holds a public advisory meeting, submits the rule set to the Joint Committee on Administrative Rules (JCAR) and files with the Secretary of State; rules take effect on a fixed delay after filing. JCAR can object, which leads to bills to rescind or stay the rule, but no legislative approval vote is required.

Cycle. Statute requires updates at least once every 3 years to coincide with the national code change cycle; Michigan has run behind that schedule for some codes.

How it was checked
