Welcome to MUD!

Due to concerns surrounding Corvid-19, we are TEMPORARILY CLOSED at least through April 5. Although we usually love sharing tools and sharing skills, neither of these things feel socially responsible to us right now.

If you have tools checked out, please hold onto them until we reopen. All late fees will be waived. If you have already purchased a workshop ticket, it will be honored at the rescheduled date. If that date doesn’t work for you we will happily issue you a refund.

Additionally, our annual Earth Day celebration will be postponed until the summer, date TBA. Thank you for your patience as we navigate this uncertain time, and be well.

About Us

The Missoula Urban Demonstration (MUD) Project empowers people to build a more sustainable community through tool sharing and hands-on learning. We have been providing Missoula with the tools for sustainable living since 1981!


Learn the skills to do things for yourself! We offer a variety of skill-building workshops and educational opportunities each year. Get 1/2 off all workshops when you become a MUD member!


Become a MUD member today to rent from our tool library and choose from over 3,000 tools for your next DIY project. Need some inspiration? Our demonstration site features sustainable projects you can replicate in your home!


We believe in the importance of celebrating sustainability, community, and coming together to improve our world. Join us for our annual Earth Day Celebration and Garden Party!
