City of Missoula Standards and Specifications Manual Update

About the City of Missoula Standards and Specifications Manual

The City of Missoula has updated its Standards and Specifications Manual (COMSSM) to better align with upcoming changes to the Unified Development Code (UDC) and the City’s newly adopted Our Missoula 2045 Land Use Plan.

The manual brings together design standards, administrative rules, and standard details into one clear, consistent resource for Missoula’s engineering and contracting community. These updates clarify how City code requirements are met and ensure our infrastructure supports safe, efficient, and well-designed development.

Draft Proposed Manual - Review Period Now Closed

Commenting on the draft City of Missoula Standards and Specifications Manual was open until December 1st. The public comment period is now closed, and City staff are reviewing all feedback submitted.

Thank you to everyone who attended the public meetings, open houses, and provided feedback on the new draft of the COMSSM. The full proposed manual has been closed on this page while we review submitted comments. We will continue to update this page as we move this project forward.
