The Advantages of Pole Barns

In Spokane, your buildings need to work as hard as you do. Whether you’re looking for a professional workshop in the Valley, a hay barn in Deer Park, or a custom garage on the South Hill, pole barns (post-frame construction) offer the best balance of durability, speed, and value.

Built for Spokane Snow Loads

Spokane sees heavy snow loads, strong winds, and wide seasonal temperature swings. Pole barn construction uses engineered posts and trusses designed to handle snow accumulation and wind resistance—making them ideal for farms, residential shops, and commercial buildings throughout the Inland Northwest.

Cost-Effective & Faster Build Times

Traditional stick-frame buildings require continuous concrete foundations, which are expensive and time-consuming. Pole barns utilize a post-frame system that requires significantly less excavation. This means that lower initial costs, saving on concrete and intensive labor. It also means that there will be a rapid turnaround: We get you under a roof faster, often in a matter of weeks, not months.

Maximum Open Space (Clear-Span Design)

Without the need for interior load-bearing walls, pole barns offer massive, unobstructed interior spaces. This makes them the "superior" choice for Agricultural Storage, Workshops and Vehicle Collections.

Superior Insulation & Efficiency

Don't let the Spokane winters stop your productivity. The wide spacing between posts allows for extra-thick insulation blankets or spray foam, creating a highly thermal-efficient environment that is easier to heat in January and keep cool in July.

Versatile Aesthetics

Just because it’s a "barn" doesn't mean it has to look like one. From modern metal siding and wainscoting to traditional wood finishes and wrap-around porches, we design your building to enhance your property’s curb appeal and long-term value.

FAQS About Building Pole Barns in Spokane

Typically, the on-site construction for a standard pole building takes between one to four weeks. However, the total project timeline depends on several key factors:

  • Size and Complexity: A simple two-car garage will be completed much faster than a large, multi-bay commercial workshop with interior walls and custom features.

  • Site Preparation: The timeline begins once the site is fully prepared. If your property requires extensive excavation, grading, or tree removal, this will add time before we can start building.

  • Customizations: Features like insulation packages, extensive electrical work, plumbing, and interior finishing will extend the construction phase.

  • Permitting & Design: The pre-construction phase, which includes design and securing permits from Spokane County, also contributes to the overall schedule. We help streamline this process, but it’s an important factor to consider.

For every project, we provide a detailed and realistic timeline once we have finalized the design and scope of work.

 

 

Yes, a building permit is required for virtually all new pole barns and pole buildings in Spokane County. If your building includes electricity or plumbing, separate electrical and plumbing permits will also be necessary.

The permitting process ensures that your new structure is safe, compliant with local zoning laws, and meets all building codes designed to handle challenges like our region’s heavy snow loads.

Navigating the permitting process can seem daunting, but our team has extensive experience working with Spokane County and other local jurisdictions like Deer Park and Chattaroy. We can manage the entire application process on your behalf to ensure everything is submitted correctly for a smooth and timely approval.

Absolutely. A modern, professionally engineered pole building is just as durable, and in some cases more resilient, than traditional structures. The term “pole barn” can sometimes bring to mind old, rustic buildings, but today’s post-frame construction is a sophisticated and robust building method.

Here’s why they are so durable:

  • Solid Foundation: Large posts are set deep into the ground, creating an exceptionally strong foundation that effectively resists wind uplift and frost heave.

  • Superior Strength: The interlocking frame design efficiently transfers energy and loads—like heavy snow—directly to the ground, creating a stronger overall structure with less material.

  • Resilience: Post-frame buildings have a natural flexibility that can make them more resistant to seismic events and soil shifting compared to more rigid structures.

When built with high-quality materials by an experienced crew, your pole building is an investment that will last for decades.

Yes, we are a full-service general contractor and can manage your entire project from the ground up. This includes all necessary site preparation and concrete work.

Our comprehensive services save you the stress and hassle of coordinating multiple different companies. We handle:

  • Site Preparation: Land clearing, excavation, and leveling the building pad.

  • Grading & Drainage: Ensuring the surrounding land is properly sloped to direct water away from your foundation.

  • Concrete: Pouring high-strength concrete slab floors, foundations, aprons, and walkways.

By managing these critical first steps, we guarantee a seamless workflow and a foundation that is perfectly prepared for the structure it will support.
