The construction industry is experiencing unprecedented supply chain issues which has not only affected costs, but also inventory and delivery timelines. Due to nationwide shortages of various building materials, the city of Aurora is extending the deadline by which all submittals will be reviewed for compliance with the 2021 codes until May 1, 2023. 

There will be one exception to the delayed implementation date:
Due to the safety issues involved, the City of Aurora will begin enforcing IRC Section R324.6.1 'Pathways' from the 2021 International Residential Code (IRC) on all solar permits submitted after October 31, 2022. 

In determining which code series to utilize for you project please be aware that once chosen, 2015 or 2021, the same series must be utilized throughout the plan review and inspection processes.
