Transitioning to the UDO

We have changed over to the UDO. Find all the information you need on this transition here.

The UDO is effective as of June 1, 2023.

Text Amendments

The UDO is a “living” document, that will continue to be updated and modified through text amendments. Learn more about currently proposed text amendments in the link below.

Alignment Rezoning

Alignment Rezoning (ARZ) is the process of aligning the new UDO zoning districts with the 2040 Policy Map Place Types. Additionally, the ARZ process will develop criteria to guide proposed zoning changes based on Place Types and development context.


UDO University offered a series of virtual training opportunities to assist in learning about the UDO and to ask questions of subject matter experts. Virtual session presentations and playbacks are now available at the link below.
