However, Riverton City Code § 15.10.010 itself dynamically adopts 'the most recent version... adopted by the state of Utah' and states that state updates automatically update Riverton's code with no separate city action required — so as a matter of law the 2024 editions already govern in Riverton regardless of the outdated summary page. Confirmed directly against Utah Code § 15A-2-103 (version effective 7/1/2026, superseded 1/1/2027) at le.utah.gov.. Local amendments apply — see the Riverton overview page for the full list.
