Is It Legal to Build a Tiny House in Montana?

A tiny house is a small residence, typically between 100 and 400 square feet, that is gaining popularity as an alternative to traditional, full-sized homes. In Montana, it is legal to build a tiny house on wheels, however it is illegal to live in it full-time. The state does not consider tiny houses on wheels to be real property, and therefore does not allow them to be used as permanent dwellings.

Tiny houses on foundations are legal, but they must meet the same building codes as traditional houses and must be placed on a permanent foundation. If your tiny house is on a permanent foundation and meets the building codes, it is considered a real property and can be used as a permanent residence. However, it must also be connected to utilities like water, sewer and electricity. If you are unable to connect to these services, your tiny house may not be considered legal and you may be subject to fines and other penalties.
