The City has updated the IDO each year since it was adopted in 2017 and went into effect on May 17, 2018. As of 2023, the City will update the IDO every other year in odd years. The next update will be in 2025.

Development approved under each version of the IDO is held to the regulations that were in place when the application was accepted as complete and began the City's review/decision process for each development project. For that reason, the City keeps an archive of IDO documents effective in each year. 

• See Planning webpage for the full legislative history of the IDO.

Planning staff incorporates adopted changes into the following documents:

• an archive draft, which notes changes from the previous year with footnotes and with the colored text:
  • red for citywide EPC changes.
  • green for citywide Council changes.
  • blue for small area changes
• the effective document, which includes a summary table of amendments over time, which is posted:
  • on this interactive IDO website.
  • on the Planning webpage.
  • on the City's Amlegal website.
