Mass excavation, over-excavation for expansive soils, storm and sanitary runs, and parking base in Spokane Valley subdivisions.
CY · LF · TONSpokane Valley issued 855 new privately-owned residential units in 2025, 79% of them multifamily. We produce CSI-organized material and labor takeoffs for bidders, builders and owners working in Spokane County.
Four cost drivers dominate here: multifamily podium and wood-frame construction, cold inland-northwest winters that drive frost-depth footings and longer concrete cure schedules, expansive and rocky soils requiring over-excavation, and a small local subcontractor pool that pushes labor rates and bid coverage. ZIP-code-adjusted pricing matters because Spokane Valley material and labor costs diverge from Seattle-area rates.
Spokane Valley sits east of Spokane in Spokane County, along the I-90 corridor and the Spokane River. The city's permit volume is heavily multifamily: of 855 new privately-owned residential units permitted in 2025, 678 were multifamily and 177 were single-family, with a permitted value of $186M and an average of $217,700 per unit. That mix means most takeoffs here are for apartment and townhome shells, not custom single-family homes. The 2025 total was up 80% from 474 units in 2024, so bid competition is following the volume.
We price with ZIP-code-adjusted material and labor data, so a Spokane Valley concrete or framing package reflects local costs rather than a national average. The region's cold winters push footings to frost depth, extend concrete cure schedules, and add insulation and freeze protection to the envelope scope. Glacial outwash and expansive soils across the Spokane Valley floor often require over-excavation and import, which is a line item bidders miss when they price from a national template.
Deliverables arrive in Excel and PDF, sorted by CSI MasterFormat division, with marked-up plan sets. Turnaround is 24–48 hours for most projects, with rush available. If you bid work in the Spokane area, start with our Washington construction estimating overview, then send plans through the estimate request page.
For bidders. You need quantities you can defend in a bid review. We return line items by division with waste factors, unit costs and marked-up sheets, so you can see exactly where the concrete, framing and MEP dollars sit before you submit.
For builders. You need a budget that holds through buyout. We break scopes into packages you can send to subs, flag missing scope between trades, and price with Spokane Valley ZIP-code labor and material rates instead of a regional average.
For owners. You need a cost baseline before design is finished. We quantify what is drawn, note what is missing, and give you a division-level budget you can track as the drawings develop toward permit.

855 new housing units in 2025 (+80.4% vs 2024).
177 single-family · 678 multifamily (79%).
Spokane Valley permitted 855 new privately-owned residential units in 2025, up from 474 in 2024 — an 80% increase. Multifamily accounted for 678 units, or 79% of the total, against 177 single-family. The permitted value was $186M, averaging $217,700 per unit. For bidders, that means the competitive set is apartment and townhome work, where the shell, sitework and MEP packages carry the budget and where unit-count pricing is the norm. A takeoff that prices only the building and skips site utilities, retaining walls or parking will not survive buyout. Our multi-family estimating services are built around that package structure, and the statewide picture is on the Washington construction estimating page.
Spokane Valley ranks 3 of 25 among the Washington cities we cover by residential units permitted, at 5.3% of the 16,004-unit covered total. That is real volume, but it is spread across a limited number of local general contractors and subcontractors. Bid coverage tightens in earthwork, concrete and drywall, and labor rates reflect the smaller pool. If you are comparing this market to western Washington, our Kent construction estimating and Everett construction estimating pages show how the same scopes price differently on the west side. Confirm current permit fees and submittal requirements with the City of Spokane Valley building department.
These are the scopes we quantify most often for Spokane Valley multifamily, commercial and industrial work.

The 2025 permit mix in Spokane Valley was 79% multifamily, so most of our takeoffs here are apartment and townhome shells, with single-family and commercial work filling out the rest.
Wood-framed, three- and four-story apartment buildings are the dominant permit type in Spokane Valley. We take off the full shell, from footings and slab through framing, sheathing, roofing and unit finishes.
Watch for: Unit-to-unit repetition, corridor MEP chases, fire-rated assemblies
Attached townhome rows appear throughout the valley's infill sites. Party walls, separate utilities and repeated floor plans change both the framing takeoff and the MEP rough-in quantities.
Watch for: Party-wall fire ratings, per-unit utility runs, stair framing
The city permitted 177 single-family units in 2025. These range from production homes to custom builds, and we price framing, envelope and finishes from the plan set with waste factors by trade.
Watch for: Frost-depth foundations, roof complexity, window and door schedules
Retail, restaurant and office projects follow the I-90 corridor and the city's commercial nodes. We quantify tenant improvements, structural steel, storefront glazing and MEP distribution from permit drawings.
Watch for: Tenant improvement vs. core shell, storefront systems, hood and grease duct
Warehouse and light industrial buildings serve the valley's logistics and manufacturing base. Slab thickness, column spacing and dock equipment drive the concrete and steel quantities.

Schools, churches and municipal buildings in the Spokane Valley area need takeoffs that hold up to public bid scrutiny. We price by CSI division with clear quantity backup for each line.
Watch for: Prevailing wage scopes, phased occupancy, code-driven egress
Spokane Valley pricing is not the same as pricing in Seattle or Portland. These are the local conditions that move quantities and unit costs on a takeoff here.
The City of Spokane Valley administers its own building permits, plan review and inspections, and Spokane County handles work outside the city limits. Washington adopts the IBC, IRC, IECC, NEC and the Uniform Plumbing Code on a statewide cycle, with local amendments. Confirm the adopted edition and any local amendments with the building department before you lock quantities, because egress, energy and sprinkler requirements shift between cycles.
City of Spokane Valley Community and Economic Development · Spokane County Building and Planning · Washington State Building Code CouncilGlacial outwash sands and gravels, plus expansive clay pockets, are common across the Spokane Valley floor. Geotechnical reports often call for over-excavation and import of structural fill, and footings must bear below frost depth. That adds excavation, backfill, import and concrete volume that a template takeoff will miss. Price the geotech recommendation, not the typical detail.
Geotechnical report · Frost-depth footings · Structural fill importSpokane Valley winters bring hard freezes, snow load and short curing windows. Concrete placed in cold weather needs heated enclosures, accelerators or blankets, and masonry and stucco schedules stretch. Roof snow load and ice-dam detailing affect truss design and eave assemblies. Carry cold-weather protection and winter conditions as separate line items rather than burying them in general conditions.
Snow load design · Cold-weather concrete · Ice dam and eave detailingThe Spokane metro has a smaller skilled-trade pool than the Puget Sound, and multifamily volume competes for the same framing, drywall and mechanical crews. That affects both productivity assumptions and overtime exposure on fast schedules. We price labor with ZIP-code-adjusted rates for the Spokane Valley area, so your bid reflects what crews here actually cost rather than a West Side average.
ZIP-code-adjusted labor · Framing crew availability · Overtime exposureSites along the Spokane River and its tributaries can trigger shoreline and critical-area review, and stormwater must be managed under the city's drainage requirements. Sloped lots need retaining walls, and flat sites need engineered storm systems and grading. We quantify cut, fill, import, export, storm pipe and structures as separate pay items so the site package does not hide in the building budget. Confirm local drainage requirements with the city or county.
Stormwater management · Retaining walls · Shoreline and critical areasSpokane Valley sits on I-90, so most material delivers without a long haul, but specialty items and some mechanical equipment still ship from west of the mountains. Washington applies retail sales tax to construction materials, and contractors must account for it in their buyout. We keep material pricing separate from labor so you can see tax and freight exposure clearly.
I-90 freight corridor · Washington retail sales tax · Material buyoutSpokane Valley's mix of multifamily and single-family permits, its cold winters and its alluvial soils change what you measure and how you price it. Here is how those conditions land in the divisions we build most.
Spokane Valley sits on glacial outwash and alluvial soils along the Spokane River corridor, so a takeoff that assumes uniform bearing is a takeoff that will get revised. We measure stripping by area from the grading plan, then break cut and fill into benches keyed to the geotech boring log rather than one blended number. Over-excavation under footings is carried as a separate line so the owner can see it, not buried in a general condition. For sites with river-adjacent groundwater, we add dewatering and shoring allowances by linear foot of trench. Our sitework estimating services page shows the full division breakdown we deliver.
Wood-frame multifamily dominates the valley's permit volume, so wall, floor and roof framing get measured to the piece rather than by a square-foot allowance. We count studs by wall type and height, including plates, blocking and headers, then apply a waste factor typical for dimensional lumber. Roof trusses are taken off by count from the truss packet, with sheathing and fascia separate. I-joist floors are measured by piece from the layout, with rim board and hangers. Our framing estimating services page describes the format, and multi-family estimating services covers full building packages.
The valley's multifamily share means repeated unit plans, so MEP takeoffs are best done by typical unit and multiplied, with corridor, riser and common-area runs measured separately. We count fixtures, receptacles, devices and diffusers by unit type, then add the vertical riser and meter stack by floor. Heating in this climate is a real cost driver: we take off the heating plant by capacity and count, not by allowance. Our MEP estimating services page covers the divisions we deliver and the input we need from you — the mechanical and electrical schedules, not just the floor plans.
Frost depth in this region drives footing bottoms well below what a coastal Washington takeoff would show, and that depth flows straight into form area, rebar, concrete volume and backfill. We take off footings by linear foot with a separate width and depth column, then convert to cubic yards with a waste factor typical for formed foundations. Slab-on-grade for the valley's multifamily podium and garage work is measured by square foot with thickened edges, vapor barrier and mesh broken out separately. Our concrete estimating services page lists the line items we return, and foundation estimating services covers the deeper residential packages.
Snow load and freeze-thaw cycling in Spokane Valley push roof assemblies toward steeper slopes, ice-and-water membrane at eaves and heavier underlayment than a western Washington takeoff would carry. We measure roof area by plane from the elevation and roof plan, then add eave and valley linear feet for membrane and flashing. Metal roofing is taken off by panel count and trim pieces, not just square footage. Wall envelope — WRB, rigid insulation, flashing at openings — is measured by area with penetrations deducted. Our roofing estimating services page shows the assembly-level detail we provide.
Quick check for a single element. For a full drawing set, send the plans and we measure everything, including the items calculators miss.
Typical waste: 3–5% for slabs, 5–10% for footings and walls. Truck count assumes 10 CY loads; confirm load size with your ready-mix supplier.

This example shows how a continuous footing takeoff is built from the foundation plan, then converted to cubic yards with a waste factor. Dimensions are illustrative — your plan's footing sizes and frost depth will differ, and the local building department confirms the adopted code edition.
Assume a rectangular building with a perimeter of 320 linear feet and one interior bearing line of 90 linear feet, for a total of 410 linear feet of continuous footing. The footing is 24 inches wide and 12 inches deep. Footing bottom depth below grade is set by frost requirements and the geotech report, but depth below grade does not change the concrete volume — only the footing's own cross-section does.
| Step | Calculation | Result |
|---|---|---|
| Total footing length | 320 LF perimeter + 90 LF interior | 410 LF |
| Cross-section area | 24 in ÷ 12 = 2.0 ft; 12 in ÷ 12 = 1.0 ft; 2.0 × 1.0 | 2.00 SF |
| Net concrete volume | 410 LF × 2.00 SF | 820 CF |
| Convert to cubic yards | 820 CF ÷ 27 | 30.4 CY |
| Waste factor (typical 5% for formed footings) | 30.4 × 1.05 | 31.9 CY |
| Order quantity | Round up to whole yards | 32 CY |
Two things estimators miss here. First, the interior bearing line is often shown on the framing plan but not repeated on the foundation plan, so it gets dropped. Second, footing intersections at corners and T-joints are double-counted if you measure each wall run to its full length; we either deduct the overlap or measure centerline-to-centerline and note the convention in the takeoff. Rebar, form area and backfill are taken off from the same 410 LF, so an error in length propagates through three divisions. If you want this run against your own plans, our residential estimating services and commercial estimating services teams both handle footing packages, and you can send drawings through the get an estimate page.
The figures come from the U.S. Census Bureau's Building Permits Survey for 2025, and they count new privately-owned residential units permitted by the city itself — not commercial permits, not remodels, not units permitted by Spokane County outside city limits. In 2025 that was 855 units, up from 474 in 2024, with 177 single-family and 678 multifamily units. The permitted value was $186M, an average of $217,700 per unit.
Of the 855 residential units permitted in 2025, 678 were multifamily — about 79% of the total. That share shapes how we take off work here: repeated unit plans let us measure one typical unit and multiply, but corridor, riser, stair and common-area scope still has to be measured separately. If your project is a podium or garden-style building, our multi-family estimating services page shows the package we return.
Colder winters and freeze-thaw cycling mean deeper footing bottoms, ice-and-water membrane at eaves and valleys, and temporary heat or freeze protection during cold-weather concrete and masonry. None of those are optional line items here. If your bid was built from a Seattle-area template, check Division 03 for footing depth and Division 07 for the roof assembly before you send it.
Much of the valley sits on glacial outwash and alluvial deposits, with variability over short distances and groundwater concerns near the Spokane River corridor. We take cut, fill and over-excavation from the geotech boring log rather than assuming uniform bearing, and we carry undercut as a separate line. Confirm the required bearing and any over-excavation depth with the geotechnical engineer and the local building department before pricing.
Architectural, structural, civil and MEP plan sets, the specifications, the geotech report, and any addenda. For multifamily, a unit-type matrix and the truss or joist layout save time. We return Excel and PDF organized by CSI MasterFormat division with marked-up plan sets, so your estimator can trace every quantity back to the sheet it came from.
Most projects come back in 24 to 48 hours, with rush available. Larger multifamily and commercial packages take longer, and we will tell you the date before we start rather than after. If you have a bid date, send the plans with that date in the subject line and we will confirm whether the schedule works.
Yes. We use ZIP-code-adjusted material and labor pricing with RSMeans data as the base, so the Spokane Valley and Spokane County rates in your estimate reflect this market rather than a national average. Sales tax is applied by jurisdiction and delivery point, which matters on a bid where materials are bought in one place and delivered to another.
Yes. We cover the rest of the state, including Kent, Everett, Renton, Federal Way, Yakima and Kirkland, and the Washington construction estimating page lists everything we handle statewide. If your project is in one of those cities, use the city page for that market so the local code and cost notes match.
Foundation and earthwork scope. Footing depth, over-excavation and dewatering are the items most often left out or carried as an allowance, and they are the items that move most when the geotech report is read closely. Measuring them as separate line items on the front end is cheaper than discovering them after the excavator mobilizes.
Yes. Warehouse, light industrial, retail and office packages are all in scope, and our industrial estimating services and commercial estimating services pages describe the divisions we deliver. Industrial work here often turns on slab thickness, racking loads and utility capacity, so include the structural and civil sheets with the architectural set.
Send your plan set and bid date, and we will return a division-by-division takeoff in Excel and PDF with marked-up drawings, typically within 24 to 48 hours.
