Editorial policy

Conservative by design.

We separate the code currently applicable from the state’s 2026 adoption status. We report what official records confirm—not what schedules merely anticipate.

  1. 01Official sources firstState boards, agencies, administrative rules, and legislation take precedence.
  2. 02Dates require confirmationAnticipated dates are described in notes, not presented as effective dates.
  3. 03Verify with your AHJLocal amendments and enforcement can vary. Always confirm project requirements.
