What makes construction estimating in Hillsboro, OR different?
Hillsboro pricing is driven by Washington County soil and drainage conditions, wet-season sitework windows, Portland-area semiconductor and industrial investment, suburban single-family growth, and ZIP-adjusted material and labor rates. These factors move earthwork, concrete, framing, roofing and MEP line items more than a generic state average would.
- Hillsboro permitted 313 new housing units in 2025, #11 among the Oregon cities we cover.
- About 6% were in multifamily buildings; 94% were single-family.
- Permit volume was down 47% compared with 2024.
Hillsboro sits in Washington County, where the Portland-area semiconductor buildout and Willamette Valley suburban growth keep both industrial and residential work moving. The city issued 313 new privately-owned residential units in 2025, down from 594 in 2024, with 295 single-family and 18 multifamily units. That mix means most of the residential takeoff volume here is detached housing, not podium or wrap construction. You can see how that compares with other markets on our Oregon construction estimating page.
We build estimates from the plans you send, not from square-foot averages. A Hillsboro single-family takeoff typically runs through footing and stem wall concrete, slab-on-grade, floor and roof framing, exterior envelope, insulation, drywall, and MEP rough-in, each priced with ZIP-code-adjusted material and labor. Sitework packages around Hillsboro often carry extra drainage and erosion-control scope because of winter rainfall and local soils. If your project is closer to the I-5 corridor, our Salem construction estimating and Beaverton construction estimating pages cover those markets with the same format.

295 single-family · 18 multifamily (6%).
Residential permit volume dropped, but single-family still dominates
Hillsboro issued 313 new privately-owned residential units in 2025, a 47% decline from 594 in 2024. Single-family units accounted for 295 of that total, or 94%, while multifamily contributed just 18 units, about 6%. Permitted value was $99M, averaging $315,000 per unit. For bidders, that means the active residential bid list is mostly detached homes and small subdivisions, not large apartment packages. Framing, foundation and roofing scopes will see more competition per project, so quantity accuracy on those divisions matters more than ever. The city ranked 11 of 25 among covered state cities by units and represented 3.3% of the 9,431 statewide units. If you also bid south of here, our Eugene construction estimating page tracks a different demand pattern.
Industrial and semiconductor work keeps commercial trades busy
Portland-area semiconductor investment is the main non-residential driver in this submarket, and it pulls concrete, structural steel, process piping and electrical contractors toward industrial scopes. Those projects price differently from residential work: heavier foundations, tighter tolerance specs, and MEP packages that run a much larger share of total cost. When residential permits slow, bidders who can price both sides of the market stay busier. We estimate industrial and commercial scopes with the same CSI-division structure, so your team can compare a tenant improvement against a cleanroom support building without rebuilding the format. For contractors working across the metro, our Gresham construction estimating and Medford construction estimating pages cover those nearby markets.

Who orders Hillsboro estimates from us
General contractors bidding Hillsboro subdivisions
You are pricing 20 to 60 detached lots off one plan set and need per-unit quantities for concrete, framing and roofing that hold up across varied lot grades in Washington County.
Framing and concrete subcontractors
You buy lumber and ready-mix on short cycles, so you need board-foot and cubic-yard takeoffs with waste factors you can hand straight to your supplier before the bid date.
Custom home builders near the West Hills
Steep lots, daylight basements and engineered retaining walls change excavation and foundation scope enough that square-foot pricing misses the real cost.
Industrial and semiconductor support contractors
Trades near the Ronler Acres and Shute Road campuses need cleanroom-adjacent MEP, process piping and equipment pad quantities separated from base building scope.
Multifamily and mixed-use developers
With only 18 multifamily units permitted in 2025, each project is negotiated rather than bid, so you need a defensible budget before you commit to a pro forma.
Architects and owners budgeting early
You want a division-by-division budget from schematic drawings, with missing scope flagged, so design decisions are made against numbers instead of allowances.

Local factors
What changes a construction estimate in Hillsboro
Two bids on the same drawings can differ by a wide margin here because of ground conditions, permitting sequence and how far materials travel to the site.
Permitting and code review
Hillsboro reviews building permits through the city, and Washington County coordinates some road and drainage approvals. Oregon adopts statewide building and residential codes, but the edition in force changes over time, so confirm the adopted edition and any local amendments with the building department before you lock pricing. Review timelines affect escalation on long-lead items more than they affect labor.
City of Hillsboro building department · Washington County · Oregon statewide codesSoils and foundation depth
Much of the eastern Tualatin Valley sits on older alluvial and volcanic soils, and parts of the area carry expansive clay that drives over-excavation and deeper footings. A geotechnical report changes footing widths, stem wall height and drain detail. If you bid from drawings alone, carry a line for unsuitable subgrade and note it as an assumption rather than burying it in the concrete unit price.
Geotechnical report · Footing and stem wall concrete · Subgrade correctionWinter rainfall and drainage
Wet-season work from October through spring adds temporary erosion control, gravel working pads, silt fence, inlet protection and dewatering. Roofing and exterior painting schedules stretch, which carries general conditions longer. Sitework packages need catch basins, storm line and footing drain quantities measured from the civil sheets, not carried as a lump sum.
Erosion control plan · Storm drainage · DewateringLabor availability and wage rates
Crews here move between residential subdivisions, industrial campuses and Portland-metro commercial work, so trade availability tightens when large projects pull labor. Your estimate should show labor hours by trade with a stated burden and overtime assumption, so you can test the number against the crew you actually have rather than a regional average.
Labor burden · Trade hours · Overtime assumptionLand use and site constraints
Hillsboro's planning rules and Washington County's urban growth boundary shape lot sizes, setbacks and where you can place impervious surface. Those constraints change retaining wall lengths, driveway grades and stormwater detention volume. Estimating from the civil and landscape sheets together catches the walls and plantings that a building-only takeoff misses.
Urban growth boundary · Setbacks and lot coverage · Stormwater detentionMaterial logistics and sourcing
Most structural lumber, ready-mix and finishes come from the Portland metro, but specialty items such as engineered wood, custom windows and process equipment can ship from out of state. Freight, lead time and sales tax treatment belong in the estimate. Oregon has no statewide sales tax, so confirm any local or use-tax treatment on materials with your accountant.

How Hillsboro conditions show up in a takeoff, trade by trade
Hillsboro sits in Washington County, where wet winters, volcanic and alluvial soils, and a steady mix of residential and high-tech industrial work shape what a takeoff must capture. Here is how that plays out trade by trade.
Sitework and earthwork
Hillsboro's wet season means you cannot take the geotech report's bearing depth at face value. A sitework takeoff here has to carry stripping depths, unsuitable soil over-excavation, structural fill import, and perimeter drainage separate from the building scope. On the sloped west-side lots, add temporary erosion control, silt fence, and construction entrance rock as measured line items, not allowances. If the civil plan shows a storm line crossing the building pad, price the bedding, backfill, and compaction in lifts by station. We break these out under CSI 31 00 00 so your excavator's bid and your site package reconcile. See our sitework estimating services for the unit breakdown we use.
Framing and envelope
Oregon's energy code pushes wall assemblies toward continuous exterior insulation and tighter air sealing, which changes the framing takeoff more than most builders expect. We measure plates, studs at the actual on-center spacing, headers by size and span, joists, sheathing, and blocking by linear foot, then add a waste factor typical for the material. On the envelope side, house wrap, flashing at openings, and rainscreen battens need their own lines. Roof framing over a cathedral ceiling gets counted differently than a vented attic. Our framing estimating services page covers how we separate structural from finish carpentry so your framing sub's bid lines up with the plan.
MEP and specialty systems
The semiconductor and advanced manufacturing work around Hillsboro pulls MEP scopes toward cleanroom-grade distribution, process piping, and high-density electrical, while residential work stays closer to standard heat pump and ducted systems. Either way, an MEP takeoff has to count fixtures by type, devices by count, home runs by length, and pipe by size and material. Fire sprinkler coverage under NFPA 13 is measured by head count and branch line length. We separate mechanical, electrical, plumbing, and fire protection under their own MasterFormat divisions so a specialty contractor can price their piece without sorting through another trade's quantities. Our MEP estimating services page lists what we need to start.
Concrete and foundations
Washington County footings often bear on stiff silt or weathered basalt, which pushes footing widths and stem wall heights beyond the default detail. A concrete takeoff for a Hillsboro project should measure continuous footings by linear foot at the actual width and depth, pad footings by count, slab-on-grade by square foot with thickened edges, and garage slabs separately. Add vapor barrier, rigid insulation under slab where energy code requires it, anchor bolts, and dowels into the stem wall. Rebar is taken by bar size and total length with lap and waste. Our concrete estimating services and foundation estimating services pages show how we format these quantities for a rebar supplier or a formwork crew.
Roofing and weatherproofing
Hillsboro roofs take steady winter rain and occasional wind-driven events, so underlayment and flashing details carry real cost. A roofing takeoff here starts with the actual roof plan area, then adds slope factor, starter course, ridge and hip, valley metal, drip edge, pipe boots, and step flashing at every wall intersection. Ice and water shield is measured by the eave and valley lengths the code and manufacturer require, not by a percentage guess. Ventilation — ridge vent, soffit vent, or both — is counted by linear foot. Our roofing estimating services page shows the line format we return, with waste shown separately from net area.
Scope gaps we see on Hillsboro bids
- Over-excavation and structural fill shown on the geotech report but not carried into the sitework bid.
- Continuous exterior insulation and air sealing required by the energy code, omitted from the framing or siding scope.
- Roof underlayment and ice barrier measured by percentage instead of by eave, valley, and penetration length.
- Storm drainage, downspout tie-ins, and yard inlets left between the site package and the plumbing package.
- Temporary erosion control and winter weather protection not priced as separate line items.
- Fire sprinkler head count and branch piping missing from the MEP scope on multifamily and industrial work.

Worked example: slab-on-grade concrete for a Hillsboro single-family home
This walk-through uses illustrative dimensions for a 1,800 SF single-family slab-on-grade in Hillsboro. It shows how a takeoff moves from plan dimensions to a priced quantity with waste shown separately. Actual dimensions come from your plan set.
Step 1 — Net slab area. The conditioned footprint measures 40 ft x 45 ft = 1,800 SF. The garage is a separate 22 ft x 22 ft = 484 SF. Net slab area is 2,284 SF.
Step 2 — Slab thickness and volume. At 4 in thick, volume = 2,284 SF x (4/12) ft = 761.3 CF. Divide by 27 to get cubic yards: 761.3 / 27 = 28.2 CY.
Step 3 — Thickened edges. The perimeter of the conditioned slab is 2 x (40 + 45) = 170 LF. The garage perimeter is 2 x (22 + 22) = 88 LF. Total 258 LF. A thickened edge 12 in wide by 12 in deep adds 258 LF x 1 ft x 1 ft = 258 CF = 9.6 CY, minus the 4 in already counted in Step 2 (258 LF x 1 ft x 0.333 ft = 86 CF = 3.2 CY). Net additional edge concrete = 6.4 CY.
Step 4 — Waste. Concrete is ordered with a typical 5% waste factor for slab work. 28.2 + 6.4 = 34.6 CY net. 34.6 x 1.05 = 36.3 CY to order.
| Step | Calculation | Quantity | Unit |
|---|---|---|---|
| Net slab area | 40 x 45 + 22 x 22 | 2,284 | SF |
| Slab volume at 4 in | 2,284 x 0.333 / 27 | 28.2 | CY |
| Perimeter | 2 x (40+45) + 2 x (22+22) | 258 | LF |
| Thickened edge, additional | 258 x 1 x (1 - 0.333) / 27 | 6.4 | CY |
| Net concrete | 28.2 + 6.4 | 34.6 | CY |
| With 5% waste | 34.6 x 1.05 | 36.3 | CY |
From here, add vapor barrier at 2,284 SF plus laps, rigid insulation under the conditioned slab if the energy code requires it, rebar or mesh by area, and anchor bolts by count. Confirm the adopted code edition with the local building department before locking the assembly. If you want this run against your own plan set, send it through our concrete estimating services page.
FAQ
Hillsboro construction estimating questions
What does a Hillsboro takeoff need that a generic one misses?
Washington County soils and the wet season drive most of it. Over-excavation and structural fill, perimeter drainage, and temporary erosion control are real line items here, not allowances. On the building side, Oregon's energy code pushes continuous exterior insulation and tighter air sealing, which changes the framing and envelope quantities. We also separate sitework from the building package so your excavator and your GC are not pricing the same cubic yard twice.
Where does the permit data on this page come from?
The residential permit figures come from the U.S. Census Bureau Building Permits Survey for 2025, counting permits issued by the city of Hillsboro for new privately-owned residential units only. That means additions, alterations, and commercial permits are not in the count. The survey showed 313 total units in 2025 against 594 in 2024, with 295 single-family and 18 multifamily units. We use it as a demand signal, not as a project list.
How does Hillsboro's climate affect a takeoff?
The wet season runs roughly October through May, so weather protection, temporary heat, and dewatering show up as real costs on winter schedules. Roofing underlayment and flashing details get specified more heavily than in drier markets. Sitework bids need erosion control and stabilized construction entrances priced by length or by count. If your schedule runs through winter, those lines belong in the takeoff, not in a contingency.
Do you handle both residential and industrial work in Hillsboro?
Yes. The Hillsboro market runs from single-family infill and multifamily to advanced manufacturing and semiconductor support buildings. The takeoff format is the same — CSI MasterFormat divisions, quantities with units, waste shown separately — but the line items differ. Residential work leans on framing, envelope, and MEP rough-in counts. Industrial work leans on structural steel, process piping, high-density electrical, and cleanroom finishes. Tell us the project type when you send plans.
What turnaround should I expect?
Most projects come back in 24 to 48 hours. Larger or multi-building packages take longer, and rush turnaround is available if your bid date is close. We return Excel and PDF organized by CSI MasterFormat division, plus marked-up plan sets so you can see exactly where each quantity came from. If your plans are still in progress, send what you have and we will note what is missing.
Can you price against RSMeans data for this area?
Yes. We use RSMeans data adjusted to Hillsboro ZIP codes for material and labor pricing, so the numbers reflect the local market rather than a national average. Labor rates in the Portland metro area differ from eastern Oregon, and material logistics from the Willamette Valley suppliers are part of that. If you have your own historical unit costs, we can apply those instead so the estimate matches how you actually buy work.
What do you need to start a takeoff?
Send the plan set, the specification book if you have one, and any geotech or civil drawings. For a complete takeoff we need architectural, structural, and MEP sheets. If the MEP drawings are not issued yet, we can take off what is available and flag the rest as a gap. Tell us the bid date and the format you want the quantities in — Excel for pricing, PDF for review, or both.
How do you handle waste factors?
Waste is shown as a separate line so you can see net quantity and gross quantity side by side. Concrete typically carries a 5% factor for slab work, framing lumber a higher factor depending on the member, roofing material a factor tied to the plan complexity. We do not bury waste in the unit price. That way, if your supplier ships short or your crew cuts differently, you can adjust the factor without rebuilding the whole takeoff.
Do you cover projects outside Hillsboro?
Yes. We cover the Portland metro and the Willamette Valley, including Salem, Beaverton, Gresham, Eugene, Bend, and Medford. Soil conditions, jurisdiction requirements, and labor markets differ across those areas, so the takeoff reflects the specific ZIP code and the local code family. If your project is in a jurisdiction we have not listed, send the address and we will confirm coverage.
What is the most common reason a Hillsboro bid comes in high?
Double-counted sitework. We regularly see the same over-excavation cubic yards priced by both the site contractor and the concrete contractor, or storm drainage carried in both the site package and the plumbing package. The second most common is a missing line — usually continuous insulation or air sealing required by the energy code — that shows up later as a change order. A clean takeoff with clear scope boundaries prevents both.
