DIY plans, or a design made for your site.
Pre-engineered plan sets
Ready-to-build container home plans for DIY builders, with instant download. A fast, affordable head start; your permit may still need local engineering, which we can add.

What shapes a container home here.
Every site is engineered for its own loads. These are the conditions we look at first in Montana.
-
Snow load
Container roofs aren’t built for heavy snow on their own. We check the roof for the local ground snow load or add a roof structure that carries it.
-
Frost depth
Footings go below the local frost line so the foundation doesn’t heave, and the floor is insulated against the cold.
-
Earthquakes · west
Seismic design of the containers, the welds and connections between them, and the foundation, where the code calls for it.
-
Local code & permits
Your city or county enforces the adopted building code and its local amendments. Containers are addressed in IBC Section 3115. We confirm your jurisdiction’s edition and requirements at the start. IBC 3115 explained →

Questions
Are shipping container homes legal in Montana?
Container homes can be built in Montana where local zoning allows a single-family home or accessory dwelling, and when the design meets the adopted building code. Zoning, HOA rules and minimum-size rules vary by city and county, so check them before you buy containers; we can tell you what the building department will want to see.
Do I need an engineer for a container home?
Almost always. Cutting openings, stacking and anchoring containers changes how they carry load, and building departments generally require sealed structural drawings and calculations. The International Building Code addresses intermodal shipping containers in Section 3115 (2021 edition and later).
Can I use your DIY plans in Montana?
Yes, as a starting point. Pre-engineered plan sets get you a long way, but a permit usually still needs site-specific engineering for your wind, snow, seismic and soil conditions. We can adapt and seal the plans for your site.
