Most custom homes in the Spokane area take about 10 to 16 months from the first design meeting to move-in day. That usually breaks down into roughly 3 to 6 months of planning, design, and permitting, followed by 7 to 10 months of actual construction. Larger homes, complex designs, steep or rocky lots, and a busy permit office can stretch that range.
A custom home is not a product off a shelf, and no honest builder can promise an exact date before the plans are final. What we can do is show you each stage, explain what happens in it, and flag where delays tend to come from. That’s what this guide is for.
At Daniel J. Olson Construction, we build custom homes for families across Spokane and the surrounding area, and the number one thing our clients tell us is that they wish they’d known what to expect sooner. So let’s walk through it.
Timeline at a Glance
| Phase | Typical Duration |
|---|---|
| 1. Discovery and budgeting | 2–4 weeks |
| 2. Land and site evaluation | 2–6 weeks (can overlap with design) |
| 3. Design and engineering | 2–4 months |
| 4. Permitting | 1–3 months |
| 5. Site prep and foundation | 4–8 weeks |
| 6. Framing and dry-in | 6–10 weeks |
| 7. Mechanical systems and insulation | 4–6 weeks |
| 8. Drywall and interior finishes | 8–12 weeks |
| 9. Exterior, landscaping, and final details | 3–6 weeks |
| 10. Inspections, walkthrough, and move-in | 1–3 weeks |
These are general ranges, not guarantees. Your own schedule will depend on your home’s size, design, and site, as well as the weather and material availability.
Phase 1: Discovery and Budgeting (2–4 Weeks)
Every good build starts with a conversation. Before anyone draws a line on paper, we sit down and talk about how you live. How many people are in the house? Do you work from home? Do you entertain often? Are you planning to age in place? Do you want a main-floor primary suite, a shop, or a space for visiting family?
This is also when we talk honestly about budget. A custom home budget should include more than construction costs. It should account for the land, site work, utilities, permits, design fees, landscaping, appliances, and a contingency fund for surprises. We recommend setting aside a cushion, because even a well-run project can run into unexpected items.
If you’re financing the build, this is the time to talk with a lender who understands construction loans. They work differently from a standard mortgage, with funds released in stages as work is completed.
What you should do in this phase: Gather photos, make a wish list, separate your must-haves from nice-to-haves, and get a realistic picture of your total budget.
Phase 2: Land and Site Evaluation (2–6 Weeks)
If you already own a lot, great. If not, this phase is where you find one. Either way, the land shapes the house as much as your wish list does.
In the Spokane area, things we look at closely include:
- Slope and soil conditions. Hillside lots, which are common around the South Hill and the north side, can offer incredible views but may need retaining walls or special foundation design.
- Rock. Basalt and rocky soil are not unusual here, and excavating through them adds time and cost.
- Utilities. Is city water and sewer available, or will you need a well and septic system? Septic and well approvals can add weeks.
- Access and setbacks. Driveway grade, easements, and local setback rules affect where the house can sit.
- Sun and views. Orientation matters for winter light, summer heat, and energy use.
Our advice is to talk with a builder before you buy land, not after. A lot that looks like a bargain can hide expensive site work.
Phase 3: Design and Engineering (2–4 Months)
This is the creative stage, and it’s often the most fun. An architect or designer turns your wish list into floor plans, elevations, and eventually full construction drawings. Along the way, you’ll review several versions, adjust room sizes, and make decisions about the exterior look.
Structural engineering happens here too. Spokane gets real winters, so roof designs need to handle snow loads, and the structure must meet the Washington State building and energy codes. Insulation, windows, heating and cooling, and ventilation are all planned during this phase.
Changes are cheap on paper and expensive once the walls are up. That’s the reason we encourage clients to take their time here. Walk through the plans, imagine your morning routine in each room, and ask questions. Finalizing selections for major items, like windows, roofing, and cabinetry layout, early helps prevent delays later.
Where delays happen: Design revisions, slow decision-making, and changing the scope after drawings are done.
Phase 4: Permitting (1–3 Months)
Once the plans are complete, they’re submitted to the city or county building department for review. Depending on where your property sits, that’s the City of Spokane, Spokane County, or a neighboring jurisdiction. Reviewers check that the plans comply with zoning, building, energy, and fire codes.
It’s common for the reviewer to come back with questions or requests for corrections. That’s normal and not a sign of a bad design. Turnaround times vary with how busy the office is, so we recommend building some flexibility into your schedule.
Your builder typically handles the permit paperwork, but you’ll still need to sign off on a few items. Other approvals may be needed as well, such as septic permits, driveway approvals, or stormwater review, depending on the site.
What you should do in this phase: Be patient, respond quickly when we need a signature or decision, and avoid making design changes that would trigger another review.
Phase 5: Site Prep and Foundation (4–8 Weeks)
Now the ground is finally moving. This phase includes:
- Clearing and grading the building area
- Excavation for the foundation and basement, if you’re including one
- Utility trenching for water, sewer or septic, power, and gas
- Footings and foundation walls, then inspections before anything gets covered
- Waterproofing and drainage around the foundation
- Backfill and slab work
Frost depth is a real consideration in Spokane. Footings need to sit below the frost line so winter freeze-thaw cycles don’t heave the foundation. Many Spokane homes include full or partial basements, which adds excavation and concrete work but also adds valuable living or storage space.
Weather matters most in this phase. Concrete needs the right conditions to cure properly, and a hard freeze or heavy rain can push the schedule. This is one reason many builders aim to get foundations in during the drier months when possible.
Phase 6: Framing and Dry-In (6–10 Weeks)
This is the phase where clients usually say, “Now it feels real.” Within days, the foundation turns into a skeleton of floors, walls, and a roofline. You can finally walk through the rooms and see the ceiling heights, window placement, and views.
After the framing is up, the crew installs the roof sheathing, house wrap, windows, and exterior doors. When the structure is protected from weather, we call it “dried in.” From this point on, interior work can continue even if the weather turns.
A framing walkthrough is one of the most important meetings of the project. It’s your last cheap chance to move a doorway, add an outlet location, or adjust a wall. Walk the house with your builder and speak up if something doesn’t feel right.
The framing inspection happens before the walls are closed up, and any issues need to be corrected before the project moves forward.
Phase 7: Mechanical Systems and Insulation (4–6 Weeks)
Inside the framed walls, the home’s “organs” go in. Plumbers, electricians, and HVAC contractors run their lines and ducts, which is known as the rough-in stage. You’ll see plumbing pipes, electrical wiring, and ductwork before they disappear behind drywall.
Then comes insulation. Given Spokane’s cold winters and warm, dry summers, this step has a big effect on comfort and utility bills. Proper insulation, air sealing, and ventilation make the home quieter, more comfortable, and more efficient. They are one of the best long-term investments in the whole project.
Several inspections happen here, including plumbing, electrical, mechanical, and insulation inspections. Passing them keeps the project on track.
What you should do in this phase: Confirm your electrical plan, such as outlets, switches, lighting locations, and any special needs like an EV charger. It’s much easier to add these now than later.
Phase 8: Drywall and Interior Finishes (8–12 Weeks)
This is the longest and busiest stretch, with many trades working in sequence. It typically includes:
- Drywall hanging, taping, and finishing
- Priming and painting
- Interior doors, trim, and baseboards
- Cabinets and countertops
- Flooring and tile
- Light fixtures, plumbing fixtures, and appliances
- Fireplace and built-ins
The order matters, and so does timing. Custom cabinets, specialty tile, windows, and some appliances can have long lead times. If your selections aren’t made on time, a single missing item can hold up several trades behind it.
That is why we ask clients to finalize their finish selections well before this phase begins. Our team provides a selection schedule so you know what’s due and when, and we help you stay within your allowances.
Phase 9: Exterior, Landscaping, and Final Details (3–6 Weeks)
While the interior comes together, work continues outside. Siding, exterior paint or stain, porches, decks, driveways, and walkways all take shape. Landscaping and grading are usually finished last, partly to avoid damage from heavy equipment and partly because weather may limit what can be planted when.
In the Spokane region, finishing exterior work late in the year can push some items, like final paving or landscaping, into the next spring. We’ll tell you up front if that’s likely so there are no surprises.
Phase 10: Inspections, Walkthrough, and Move-In (1–3 Weeks)
At the end, the home goes through final inspections. When the building department signs off and issues a certificate of occupancy, the house can legally be lived in.
Before you get the keys, we do a detailed walkthrough together. You’ll go through each room, check the finishes, test the systems, and make a punch list of any small items that need touch-ups or adjustments. We then address that list quickly. We’ll also show you how everything works, from the heating system to the water shutoff, and we’ll hand over warranty information and maintenance guidance.
Then comes the best part: moving in.
What Can Slow a Custom Home Build Down?
Even well-managed projects hit speed bumps. The most common ones we see are:
- Slow decisions. Delayed selections can hold up whole phases.
- Mid-build changes. Changing plans after work has started can mean redoing work and reordering materials.
- Weather. Spokane winters can pause concrete, framing, and exterior work.
- Material lead times. Windows, specialty items, and appliances may take longer than expected.
- Permit delays. Review times and correction requests vary.
- Surprises underground. Rock, poor soil, or utility issues can appear once digging begins.
The best way to protect your schedule is to plan carefully, decide promptly, and keep clear communication with your builder.
Tips for a Smoother Build
- Choose your builder early. Involving a builder during the design phase helps keep the plans realistic for your budget.
- Set a contingency fund. Aim to keep some money available for the unexpected.
- Make selections early. Order long-lead items as soon as plans are final.
- Stay in regular contact. Weekly updates and site visits keep everyone aligned.
- Limit changes. Every change affects cost and time.
- Visit the site, but coordinate. We love when clients stay engaged, but check in with us first for safety and scheduling.
Frequently Asked Questions
How long does it take to build a custom home in Spokane?
Most custom homes take about 10 to 16 months from the first meeting to move-in, including design and permitting. Construction alone typically takes about 7 to 10 months.
What is the first step in building a custom home?
The first step is a planning conversation with your builder to define your goals, needs, and budget. Land selection and design follow from there.
Can I build a custom home during winter in Spokane?
Yes, though the schedule needs planning around the weather. Foundation work is the most sensitive to cold, while interior work can continue year-round once the home is dried in.
Do I need to own land before talking to a builder?
No. In fact, talking to a builder before you buy land can help you avoid sites with hidden costs.
What causes the most delays?
Late selections, design changes during construction, permit review times, and weather are the most common causes.
Is a custom home more expensive than a production home?
Generally, custom homes cost more per square foot because they’re individually designed and built to your specifications. You gain control over the layout, materials, quality, and location.
