Milled in Chico, California

Log Home Kits in Montana

Sierra Log & Timber mills red cedar log home packages in Chico, California, and ships them directly to jobsites across the continental United States, Montana included. A Montana build has one code question to settle before the plans are drawn: the snow load, which the building official determines inside a certified city, county or town and the ASCE 7 Hazard Tool gives outside one.

How a package reaches a Montana site

Sierra ships complete building material packages directly to jobsites across the continental United States, Montana included, by direct-to-parcel freight delivery from the mill in Chico, California.

A package is not a rigid precut kit. Sierra's Smart Cut™ system pairs panel layout drawings with timbers labeled with exact lengths and notch locations, so the builder gets factory accuracy and the flexibility to adapt on the ground.

Every component is engineered in the Sierra facility before it ships, and the builder receives a complete, labeled shell package.

It is a type of precut… but different. The concept was built around builder speed, limiting butt joints, increased log efficiency and the ability to stage “just in time” trucks.

What Montana building departments publish about snow load

The roof, the spans and the log sizes are designed to the snow load for the site, and that load comes from the rule in force where the house is built, not from the mill. The table lists what each Montana rule on file says, in its publisher's own words, with the page it was read from and the date it was read.

The first row is the state's rule: Montana's Building Codes Program says snow loads are determined by the building official, and that outside certified city, county and town jurisdictions the design snow load is based on the ASCE 7 Hazard Tool. The rows under it are the county and city rules on file.

Where a department sets the load site by site, the parcel's figure comes from that department.

Montana's wildland urban interface code

Montana's list of current codes includes the Wildland Urban Interface Code, 2024 Edition, effective September 26, 2026, the day the 2024 edition of the International Residential Code took effect.

The Building Codes Program's list of certified city, county and town programs gives the codes each program covers, and W in that list stands for WUI. Bozeman's entry carries it.

Whether the code is enforced for a parcel is a question for the building official with jurisdiction there.

Who issues the permit, and how long it takes

Under Montana Code Annotated 50-60-102, the state building code does not apply to a residential building containing less than five dwelling units unless the local legislative body makes it applicable by ordinance or resolution.

A city, county or town may enforce a building code only where the Building Codes Program has certified its code enforcement program, and the program's page says all other areas are under the jurisdiction of the State Building Codes Bureau.

Before the plans are drawn, ask the department that issues the permit what snow load it requires for the site.

This is very open ended due to a lot of factors: terrain, design and complexity and the state you are building in. So on a fast track, you can design and build within 6 months if you are not in California or states like this that have heavy permit processes. California and other heavy permit states take approx. 4-6 months to design, engineer and get a permit (and sometimes longer due to the permit process). Once that is done, the average length of time of the build is 6-12 months depending on the builder, the location and the design complexity. Yes it can take longer than that in heavy snow areas and/or areas with really extreme land developments that have to take place to build. Of course, an owner builder can take forever to build any home. Outside of California is approximately the same for building but much faster for the design to permit process.
