What to know about permitting during the Transition Period
The new code provides for a transition period where projects submitting for approvals may be reviewed under either the new Title 22: UDC or the previous development codes. Here's what to know:
- The transition period lasts until July 2nd. All applications submitted after July 2nd are subject to the UDC, except as otherwise expressly stated
- Development review applications that can be reviewed under either the UDC or under the applicable standards and regulations in effect immediately prior to the adoption of the UDC include:
- Building permits
- Zoning compliance permits
- Design Excellence Applications submitted
- Applications that have been submitted under the current title 20 but would like to switch to review under the UDC, will need to withdraw the current application and resubmit a new application under the UDC.

What Did Code Reform Do?
Code Reform updated our zoning and development codes to implement the community vision adopted in the Our Missoula 2045 Land Use Plan. This means allowing more housing in places that allow people to live closer to where they work, shop, and find services. It also means promoting more housing diversity and affordability throughout the City, while considering how buildings integrate with the surrounding neighborhood. Lastly, Code Reform included improvements to the type and quality of public amenities that are included with new development, like streets, trails, and parks.
The Code Reform process resulted in the creation and adoption of three key materials:
- A new Unified Development Code (UDC) - The new City MCA Title 22-UDC contains all city regulations that relate to private development, including zoning, subdivision, public works, and parks and recreation regulations.
- A new Zoning Map;
- An updated and expanded City Standards & Specifications Manual.
- A new Municipal Planning Commission.
