Frequently Asked Questions

Frequently Asked

Below are answers to common questions about our cabins, construction standards, site requirements, and delivery process.

Permitting & Approvals

Are your cabins engineered to meet state and local requirements?

Yes. Our cabin plans are reviewed and signed off by a licensed professional engineer to ensure they meet applicable building codes and structural requirements.

Do you assist with permitting, or is that handled by the property owner?

If we are providing site work, foundation, or septic as part of the project, we will assist with the associated local permitting. If site work is handled by others, permitting is managed by the local contractor or the property owner. State-level approvals for the cabin itself and local site-specific permits are handled separately, and we clarify what applies early in the process so expectations are clear.

Are your cabins state-approved or permitted through the Montana Factory Built Building Program (FBBP)?

Yes. Our cabins are approved through the FBBP, which means the cabin structure itself meets state-reviewed building and engineering requirements. Local site-specific approvals—such as foundations, utilities, septic, and land-use requirements—are still handled at the county or local level.

Build Standards & Materials

What sets your cabins apart from other factory-built or shed-style cabins?

We build our cabins using the same standards we apply to permanent structures, with an emphasis on long-term performance rather than minimum requirements. Our focus is on structural integrity, durability, and materials that hold up in real conditions—not on reducing cost or build time. This approach isn’t the right fit for every buyer, but it is essential for those who value quality and longevity. Some examples of how this shows up in our cabins include:

•Andersen 100 series fiberglass windows

•Spray foam urethane insulation

•Timber-frame roof systems and traditional joinery

•Durable interior finishes, including doors, flooring, cabinetry, and countertops

•An in-house design and build process grounded in hands-on experience

Delivery & Siting

How are cabins delivered to the site?

Cabins are delivered to the site by truck and trailer. Delivery logistics are evaluated in advance to ensure the approach, placement, and access are appropriate for the specific site and cabin model.

Are cranes or special equipment required for placement?

This depends on site access, terrain, and the specific cabin model. Placement requirements are evaluated in advance so the appropriate equipment—if any—is identified before delivery.

What access is required for delivery (roads, grades, clearances)?

A minimum 10-foot-wide driveway with approximately 4 feet of clearance on each side. Approximately 14 feet of vertical clearance is required. Grades up to 7% are generally acceptable. Sites with restricted access require a site visit to assess feasibility prior to sale and delivery. We routinely evaluate challenging sites and will advise early if adjustments are needed.

What needs to be ready before delivery day?

Road or driveway access and the foundation must be complete prior to delivery.

Site Preparation & Utilities

What site preparation is required before a cabin is delivered?

We recommend a conditioned, insulated crawl space designed per local code. At minimum, a monolithic 4-inch concrete slab with a utility pit is required. We provide basic foundation plans for these options to support coordination with local contractors, if needed.

Can you assist with off-grid systems such as power, water, or septic?

Yes, we can provide a full off grid package.

What do you handle, and what does the property owner need to arrange?

We handle cabin delivery and setup, including water and sewer hookups. The property owner is responsible for licensed electrical work to complete power connection. Responsibilities are clarified in advance so there are no surprises.

Do you help coordinate foundations or site work?

We can provide a bid for a full service package—including site work, foundation, septic, and in some cases electrical—for projects within approximately 80 miles of Marion, Montana (Flathead County). Outside that range clients may work with local contractors of their choice.

What site work is required before delivery, and what is optional?

Required: driveway access and foundation. Optional: additional site work depending on project scope.

Timeline Expectations 

What is the typical build timeline once a project is scheduled?

For in-stock buildings, the build itself is already complete or nearing completion at the time of purchase. The overall timeline depends largely on required site work. Typical site work and foundation preparation takes approximately 2–3 weeks, followed by 3 days for delivery and setup. Actual timelines vary based on scope, season, and site conditions. In limited cases, we may take on custom or small-batch projects. Timelines for these projects are evaluated individually and typically range from 10–16 weeks, depending on scope and scheduling.

How do seasons affect build and delivery timing?

There are many variables that affect seasonal timing, but December through February are generally more challenging for site work and foundations due to weather conditions. Planning ahead helps lessen seasonal constraints.

What’s Included

Is delivery included in the sale price?

Delivery within 60 miles of Marion, Montana is included. Additional mileage is billed at $20 per mile. Cabin setup is included; if site access is restricted, additional charges may apply. Connection to water and sewer is included.

What is NOT included?

Items not included unless specifically arranged include site work, excavation, foundation construction, local site-specific permitting, utility service beyond basic connections, and delivery beyond the standard service area (Flathead County / 60-mile radius from Marion, Montana). Scope is clarified during the planning phase so responsibilities are clear.

Are appliances included with the cabin?

Appliances are typically included with our cabins unless otherwise specified. Specific brands, models, or configurations may vary based on availability and the individual cabin. Details are confirmed as part of the purchase agreement so expectations are clear before delivery.

Are site work and utilities part of the base purchase?

Site work, foundations, utilities, and off-grid systems are project-specific. In some cases, these can be coordinated as part of the project; in others, they are handled by local contractors. This is determined early based on location and scope.
