1. What Does “Cost Per Square Foot” Really Mean?

When we talk about cost per square foot, we’re referring to the total project cost divided by the finished square footage of the building. This includes:

• Materials

• Labor

• Design and engineering

• Permits

• Foundation or slab work

• Exterior and roofing

It may or may not include site prep, utilities, or interior finishes—so always clarify what’s included in any estimate you receive.

2. Baseline Price Range for Pole Barns in Spokane

As of now, most pole barns we build in the Spokane area fall into the following general price ranges:

• Basic storage buildings: $30–$50 per square foot

• Insulated shops with concrete: $50–$80 per square foot

• Finished barndominiums or living spaces: $100–$150+ per square foot

These are ballpark figures. Your final cost depends on the size, level of customization, and site-specific conditions.

3. Factors That Influence Cost Per Square Foot

Many different variables affect your pole barn’s total cost:

• Building size and footprint

• Roof style and pitch

• Number and size of doors and windows

• Siding and trim options

• Insulation and HVAC systems

• Interior finishes (drywall, cabinetry, flooring, etc.)

• Local snow/wind load requirements

We walk every client through these variables during the design process to keep costs aligned with their budget.

4. Examples by Building Type

Here’s how the cost per square foot typically breaks down by use:

• Agricultural storage (uninsulated): $30–$45

• Garage/shop with slab and electrical: $50–$75

• Barndominium with full kitchen and bath: $120–$150+

These examples reflect real projects we’ve completed in Spokane and surrounding areas.

5. How Size Affects Your Budget

Larger buildings generally have a lower cost per square foot because you're spreading fixed costs (like permitting and equipment mobilization) over more square footage.

That said, the total cost still increases—so it's important to weigh what you truly need now versus what you might want to expand later.

---

6. Interior Finishes and Their Impact

If you’re planning a livable space or finished shop, interior details can quickly drive up the cost per square foot:

• Plumbing and electrical

• Insulation and drywall

• Flooring and cabinetry

• Appliances and fixtures

We help clients prioritize their interior features based on use case and budget—without overbuilding where it’s not needed.

---

7. Site Prep and Utilities: The Hidden Costs

Don’t forget about site-related costs, which can make or break your budget:

• Excavation and grading

• Gravel or concrete pads

• Well, septic, or power trenching

• Driveway access or culverts

We always include these considerations in our proposals so you get a realistic picture of your project’s full investment.

8. Ways to Optimize Cost Without Cutting Corners

Want to keep your project affordable without sacrificing quality? Here are some proven tips:

• Choose a simple roofline and layout

• Limit the number of windows or doors

• Use metal siding and roofing for longevity

• Install insulation and slab now, finish interiors later

• Plan ahead for utilities—even if you’re not installing them right away

We’ll help you make smart trade-offs that balance cost, value, and function.
