A Custom Home Builder & General Contractor’s Guide to Building Smart & Legal in 2025
Building a home in Montana or North Dakota involves more than blueprints and hammers. Whether you’re hiring a custom home builder in Kalispell, MT or working with a general contractor in Williston, ND, understanding the permits, building codes, and inspection process is critical to a successful build.
At WBP Contracting LLC, we specialize in custom home construction, guiding homeowners through every phase—from land prep to final inspection.

1. Building Permits: The First Step for Every Custom Home Build
Before construction starts, you need the right permits. This applies whether you’re building a custom home, a barndominium, or a multi-family residence.
In counties like Flathead (Montana) and Williams (North Dakota), building permits are mandatory for:
• New home construction
• Home additions
• Electrical, plumbing, and HVAC installations
• Foundation and framing work
• Land grading and utility hookups
As your local custom home builder and general contractor, WBP handles permit applications and communicates with city or county officials on your behalf.

2. Understanding Building Codes in Montana & North Dakota
Each state follows the International Residential Code (IRC) and International Building Code (IBC), though cities and counties can have added requirements—especially for energy efficiency and site-specific conditions.
Montana (Kalispell, Whitefish):
• Enforces 2021 IRC/IBC
• Requires strict snow load and wind load calculations
• Flathead County often requires septic permits, water rights review, and soil studies
• Energy-efficient building practices are emphasized
North Dakota (Williston, Dickinson, Bismarck):
• Uses the 2021 IRC/IBC with regional adaptations
• May require stormwater permits or grading plans
• County and municipal planning departments are heavily involved in land development approvals
As a seasoned custom home builder in North Dakota, we’re familiar with local nuances that can make or break your project timeline.

3. Inspections: Protecting Your Build at Every Stage
Inspections occur throughout your construction process to verify safety and code compliance.
Typical phases include:
• Pre-pour foundation inspection
• Framing and structural rough-in
• Mechanical (HVAC), electrical, and plumbing inspections
• Energy code and insulation check
• Final inspection for Certificate of Occupancy
As your licensed general contractor and home builder, we coordinate and pass all required inspections to keep your build moving smoothly.
