Spokane Area Shop Construction: Timeline Expectations

If you’re planning to build a shop on your Spokane-area property, one of the first questions you’re likely to ask is: “How long will it take?” It’s a great question—and one that doesn’t always have a one-size-fits-all answer. But after decades of building custom shops throughout the Inland Northwest, I can give you a clear picture of what to expect when it comes to construction timelines.

At Stimson Contracting, we specialize in efficient, durable post-frame shop buildings. Whether you’re planning a basic storage structure or a fully insulated workspace with utilities, this guide will help you understand what affects the timeline and how to plan accordingly.

1. Typical Shop Construction Timeline Overview

A standard Spokane-area shop build typically takes 6–12 weeks from the start of planning to final completion. The overall timeline depends on the size of the shop, level of customization, and whether you’re adding things like insulation, utilities, or interior finishes.

2. Phase 1: Planning and Design (1–3 Weeks)

This is where your ideas take shape. During this phase, we:

• Determine size, layout, and location

• Choose doors, windows, and features

• Finalize building specs and budget

• Prepare a draft set of plans

Fast decisions here = a faster overall project.

3. Phase 2: Permits and Engineering (2–6 Weeks)

Permitting can vary based on where you’re building, but in Spokane County, we typically:

• Submit engineered plans

• Apply for building permits

• Coordinate any zoning reviews

• Await approvals from the county

We handle this process for you, but it’s often the longest phase in the timeline due to review wait times.

4. Phase 3: Site Preparation (1–2 Weeks)

Once permits are in hand, we prepare your site by:

• Clearing and leveling the ground

• Ensuring proper drainage

• Setting post footings or foundations

This phase is critical to your building’s longevity and performance—especially during Spokane’s freeze-thaw cycles.

5. Phase 4: Construction (2–6 Weeks)

With the site ready, framing begins. A typical build includes:

• Setting posts and framing the structure

• Installing trusses and roofing

• Adding siding, doors, and windows

• Pouring the concrete slab (if applicable)

A simple shell-only shop can be completed in as little as two weeks. Larger or fully customized builds may take longer.

6. Phase 5: Finishing and Utilities (Optional – 1–4 Weeks)

If your shop will include:

• Electrical (lighting, outlets, panel)

• Plumbing (bathroom, sink, floor drains)

• HVAC (heat, cooling, ventilation)

• Insulation and interior finishes

…this phase will extend the timeline, but result in a much more functional year-round workspace.

7. Factors That Can Affect Your Timeline

Every job is a little different, but some of the most common timeline influencers include:

• Weather delays (especially in winter or wet seasons)

• Permit or zoning hold-ups

• Changes to the design mid-project

• Material lead times (doors, windows, specialty finishes)

• Site conditions (poor drainage, steep slopes, etc.)

We do everything possible to anticipate and mitigate these delays.
