Milled in Chico, California
Log Home Kits in Idaho
Sierra Log & Timber mills red cedar log home packages in Chico, California, and ships them directly to jobsites across the continental United States, Idaho included. An Idaho build has one code question to settle before the plans are drawn: the snow load the county or city publishes for the site.
Checked 11 November 2026
How a package reaches an Idaho site
Sierra ships complete building material packages directly to jobsites across the continental United States, Idaho 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 Idaho 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 Idaho rule on file says, in its publisher's own words, with the page it was read from and the date it was read.
The rules on file are county and city rules. City rules are listed after the county rules, each marked with the town it applies inside. Where a department sets the load site by site, the parcel's figure comes from that department.

Who issues the permit, and how long it takes
Idaho Code 39-4116 is the state's section on local government adoption and enforcement of building codes. Under it, local governments that issue building permits and perform building code enforcement adopt, by ordinance, the International Building Code and the Idaho residential code, and a local government that had no code enforcement program may elect to implement one by passing an ordinance.
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.
