This entry previously described the 2024-cycle codes in future tense ('effective through June 30, 2026' / 'takes effect July 1, 2026'); that date has now passed, so IBC/IPC/IMC/IFGC/IECC/IEBC/residential ISPSC are now stated as CURRENT (2024 editions), while IRC (2021) and NEC (2023) remain unchanged as already correctly stated. No Washington County page listing IBC/IRC/IPC/IMC/IECC editions specifically was found on live re-check of the Community Development FAQ and Building Permit Documents pages (2026-07-16), so there is no city-page lag to record for those codes beyond the pre-existing NEC observation above..

Pool barriers must be at least 48 inches high, have no climbable features, and gates must be self-closing and self-latching per the adopted ISPSC and IRC. Contact Community Development at (435) 301-7250 for specific requirements.
