The Our Missoula: Growth Policy Update & Code Reform project is an extensive planning process that will work with the community to update Missoula's vision for future growth and to modernize the City's development regulations, one of the key tools for achieving this vision.


What Are Development Codes & Why Are They Important?

Development codes are a series of regulations that guide the design and development of cities and neighborhoods.

They include zoning code, which determines how land is used and developed. It regulates what types of development can be built in different areas (or “zones”) of a city and regulates the shape and size of parcels and buildings.

Development codes also include other regulations that guide the design of streets, open space, utilities, drainage, and other development-related issues. These regulations will all be addressed in the Code Reform phase of the Our Missoula project.

Development codes only apply when new construction or alterations to a property are proposed. It does not require residents to build or change their property retroactively. For example, the code cannot require a property owner to go back and provide affordable housing or a new park.


What Will Code Reform Do?

Code Reform will update our zoning and development codes to implement the community vision adopted in the Our Missoula 2045 Land Use Plan. This will mean allowing more housing in places that allow people to live closer to where they work, shop, and find services. It will also mean promoting more housing diversity and affordability throughout the City, while considering how buildings integrate with the surrounding neighborhood. Lastly, Code Reform will include improvements to the type and quality of public amenities that are included with new development, like streets, trails, and parks.

Code Reform will also be informed by the findings and recommendations of the Equity in Land Use Report, the Code Diagnostic, and the adopted Guiding Principles for Code Reform.


The Code Reform process will result in the creation and adoption of three key materials:

  1. A new Unified Development Code (UDC);
  2. An updated Zoning Map;
  3. And an updated City Standards & Specifications Manual.


A UDC contains all city regulations that relate to development - including zoning, subdivision, public works, and parks and recreation regulations. The goal of adopting a UDC is to provide aligned, clear, and consistent rules that result in predictable land use outcomes. A UDC will also make the development process more efficient and easier to understand for the community.

  • Code Reform Update: Continued Progress, Slight Delay

    We want to share an update on the new draft zoning districts and zoning map, referred to as our zoning framework. While we had hoped to release these materials by now, additional time is needed to complete this important and complex work. We understand the community’s eagerness to engage and the urgency of moving forward—and we sincerely apologize for the delay.

    Creating a zoning framework that meets our community’s unique needs and aspirations has presented real challenges for both our consultants and City staff. That said, steady progress is being made, and several key components are nearing completion. What has been developed so far reflects the bold, thoughtful change our community has called for—and we’re excited to share it.

    We anticipate releasing a draft of the zoning framework later this summer, followed shortly by the draft Unified Development Code. In the meantime, we will continue targeted outreach with community partners, which will be followed by broader public engagement opportunities.

    As always, public input will guide the next steps of this process, and there will be meaningful opportunities to weigh in before City Council considers adoption.

    We remain committed to an outcome that reflects our shared values and future goals. Thank you for your continued patience, participation, and partnership.

    City Council adopted the Guiding Principles for Code Reform at the June 10th City Council meeting. You can read the agenda and meeting materials here and the Guiding Principles resolution here.



    Code Diagnostic


    The Code Diagnostic is a critical first step in understanding what changes are needed to align our development regulations with our community's vision for the future. It is an analysis of our existing conditions - not a recommendation of specific code changes - and will help us construct a roadmap for reforming the code through the Our Missoula process.

    Missoula's last comprehensive development code update predates the 2015 Our Missoula Growth Policy. Since 2015, the City has adopted and updated many plans and policies related to land development that are not supported by our outdated development. We are updating the 2015 Growth Policy as part of the Our Missoula project, which also includes a comprehensive update to our development codes.

    This diagnostic identifies key issues with Missoula’s development codes and provides actionable insights and considerations for improving clarity, consistency and alignment with the community’s goals and state regulations. It is a synthesis of policy and regulatory documents, listening sessions with frequent code users in the community, staff input, and technical analyses.

    The Code Diagnostic evaluates Missoula's current development codes through the following questions:


    Alignment with Adopted Policies: How well do the codes implement adopted land development policies? Code Format & Organization: How well do the codes communicate expectations clearly and is information easy to find and understand? Development permitting processes: How well do development permit review and approval processes provide predictable, fair, and timely service?

    There are four key findings described in the Code Diagnostic:

    1. Codes present barriers to housing equity, capacity, and affordability.
    2. Codes present barriers to compatible infill development and limit diversity.
    3. Codes do not support mobility and climate policies.
    4. Codes are difficult to navigate for customers and staff.




    Guiding Principles


    The key findings of the Code Diagnostic illuminate the need for a new paradigm of development codes and approval processes to guide Missoula’s more equitable, affordable, sustainable, and resilient future. The key findings are the basis for creating the Guiding Principles for Code Reform. The City committed by resolution to use the Guiding Principles for Code Reform as the “North Star” for comprehensive code reform and they will guide all changes to the development codes and the zoning map.

    The adopted Guiding Principles for Code Reform include:

    1. Organize the codes with a clear and consistent structure that provides user-friendly navigation.
    2. Use plain language and clear graphics to make the codes accessible and understandable.
    3. Clarify and consolidate development permit review decision authority to increase predictability.
    4. Increase overall housing capacity throughout Missoula and especially near key transit corridors.
    5. Provide market-feasible incentives for Affordable Housing.
    6. Allow for more diverse housing choices and neighborhood serving uses throughout Missoula that support the updated Future Land Use Map.
    7. Promote adaptive reuse of existing buildings and prioritize growth that utilizes existing infrastructure.
    8. Promote preservation and protection of the natural environment
    9. Map zoning districts in ways that support equity; sustainability and resilience, a vibrant public realm; and a walkable and healthy community.
