The City of Bellevue adopted the 2018 I-Codes effective February 1, 2021. Plans and supporting documentation must demonstrate compliance with all currently adopted codes, including Washington State amendments and City of Bellevue amendments.
The 2020 National Electrical Code (NEC) and 2020 Washington Cities Electrical Codes became effective on October 29, 2020.
The Development Services and Fire departments will soon be adopting the 2021 International Codes, as required by state law. Following the recent State Building Code Council vote to establish a new effective date of Oct. 29, the city is waiting for the result of that action. When more information is available regarding the change to the effective dates, the Development Services Department information will be updated. Questions about code adoption can be submitted to 2021icodes@bellevuewa.gov.
