All, 
 
Earlier this month you should have received an industry notice about Clark County's 2021 IECC proposed adoption. After sending out that notice, we received a few questions on how the proposed 2021 IECC adoption may impact standard plan applications.
 
Please read the below from the Clark County Building Department:
 
The Clark County Building Department (CCBD) will allow all standard plans submitted before the 10/16/2023 effective date of the adoption ordinance to continue to use the 2018 IECC. Homebuilders are welcome to submit new standard plans that comply with the 2021 IECC at any time following the adoption date (anticipated 4/18/2023). However, any new standard plans submitted on or after the 10/16/2023 effective date of the adoption ordinance will have to comply with the 2021 IECC. Please note, this code cycle only, the County will allow you to submit up to the effective date under the 2018 IECC. However, the package must be a complete package and the County reserves the right to require incomplete “placeholder” applications that are not good “quality” to be updated to the 2021 IECC. Please be sure you are submitting in good faith with good quality plans, and the County will honor the 2018 IECC up until 10/16/23.
 
Permit applications for adjacent re-sites will be allowed to continue to use the 2018 IECC if the original standard plans were approved for compliance with the 2018 IECC, as CCBD processes adjacent re-sites as revisions. However, non-adjacent re-sites get new 43s, so any new non-adjacent re-sites that get submitted on or after the 10/16/2023 effective date of the adoption ordinance will have to comply with the 2021 IECC just like any other new standard plan submitted on or after 10/16/2023.

Lastly, please be aware we have heard that the 2024 IECC will be published sometime in January 2024, and we anticipate the entire Valley will begin their review process to adopt the 2024 entire set of codes. We presume that the “grandfathering” process and policies of all jurisdictions will be an adoptive date with 180 days until it is effective, but that it will be based on accepted plans (not submitted) new standard plans. As we know more about the 2024 code cycle, we will let you know.
