Residential takeoff
Full takeoff for detached houses on Oregon City hillside lots, from footing excavation to siding and trim.
EA · SF · LFOregon City issued 287 new single-family permits in 2025 — up from 23 the year before. We produce CSI-organized quantity takeoffs and estimates for builders working Clackamas County hillsides, with 24–48 hour turnaround.
Steep hillside lots drive retaining walls, engineered fill and deeper footings. Winter wet-season earthwork, older downtown infill with unknown utilities, Clackamas County permitting, and ZIP-adjusted material and labor pricing all move the number. Single-family detached work dominates: 287 of 287 permitted units in 2025 were single-family, with zero multifamily.
Oregon City sits at the confluence of the Willamette and Clackamas rivers, and the terrain shows up in every estimate. Lots on the bluffs and south-facing slopes often need retaining walls, benched pads and footing drains before a foundation form is set. Downtown and the McLoughlin corridor bring infill and remodel work where existing utilities, older masonry and tight staging change the labor hours. We take off the drawings you send, price them with ZIP-code-adjusted material and labor data, and return Excel and PDF files organized by CSI MasterFormat division with marked-up plan sets. If you bid Clackamas County work, our Oregon construction estimating page covers the state-level picture, and nearby Lake Oswego and Tualatin pages cover the adjacent markets.
Most of what we see in Oregon City is single-family detached — 287 new privately-owned residential units permitted in 2025, all single-family, per the U.S. Census Bureau Building Permits Survey. That means repeated scopes: excavation and shoring, foundation and flatwork, framing, roofing, siding, and MEP rough-in. We price those divisions individually so you can see where the money goes, and we flag the line items that tend to move on hillside sites: over-excavation, structural fill, retaining wall footings, and dewatering. For builders who also work the surrounding towns, our Keizer and McMinnville pages describe the same deliverable in those markets.
For bidders. Send plans and specs; we return a CSI-organized takeoff with quantities, waste factors and marked-up drawings in 24–48 hours so you can sharpen your bid before the deadline.
For builders. Use our takeoffs to order concrete, framing lumber, trusses and siding by division, with ZIP-adjusted pricing for Clackamas County suppliers and crews.
For owners. Get a line-item budget before you commit to a hillside lot or a downtown remodel, including the sitework and foundation items that drive cost in Oregon City.

287 new housing units in 2025 (+1147.8% vs 2024).
287 single-family · 0 multifamily (0%).
Oregon City permitted 287 new privately-owned residential units in 2025, up from 23 in 2024 — a 1,148% increase, and every one of those units was single-family. The permitted value was $58M, averaging $203,500 per unit. For bidders, that means the pipeline is detached houses, not apartment shells: excavation, foundation, framing, roofing and MEP for one or two units at a time. The city ranked 13th of 25 covered Oregon cities by units and accounted for about 3% of the 9,431 covered statewide units. If you are pricing several houses on similar plans, a per-plan takeoff you can reuse is worth more than a one-off estimate. Our residential estimating services cover that workflow, and the Oregon construction estimating page puts the 2025 numbers in statewide context.
Oregon City's topography and its position between the Willamette and Clackamas rivers mean many building pads require cut-and-fill, retaining walls and footing drains that a flat-lot estimate would miss. Winter and spring rain can idle excavation and concrete crews, so schedule assumptions belong in the bid. Downtown and along the McLoughlin corridor, infill projects run into older utility alignments and tight access, which raises labor hours for excavation and concrete placement. Confirm the adopted code edition and any local amendments with the Oregon City building department before you finalize scope. For the ground-up portion, our sitework estimating services and foundation estimating services break these items into measurable quantities.
We take off the divisions that dominate Oregon City work — single-family detached, hillside sitework, and downtown infill — and price them with local data.

With 287 single-family units permitted in 2025, plan repetition is the whole game. We build a per-plan takeoff you can multiply across lots and adjust only for pad and utility differences.
Older homes along the McLoughlin corridor and the historic core bring selective demo, structural upgrades and utility relocations. We quantify those line items instead of burying them in a lump sum.
You need quantities by division, not a total. Our [concrete](/concrete-estimating-services/), [framing](/framing-estimating-services/) and [roofing](/roofing-estimating-services/) takeoffs give you form area, board feet and squares with waste factors you can defend.
Before you close on a bluff lot or a parcel with a creek buffer, you want a rough order-of-magnitude budget for sitework, foundation and utilities. We price the drivers, not a guess.
When three bids come back at three different numbers, a third-party takeoff shows what the drawings actually contain. We return Excel and PDF with marked-up plan sets for your own review.
We estimate from the drawings you send, so distance is not a barrier. These are the Oregon City districts and surrounding Clackamas and Willamette Valley communities we price most often.
The 2025 permit mix here is almost entirely new single-family detached housing, with a steady layer of remodel and small commercial work. We scope each type differently because the cost drivers are different.
Sloped lots off Holcomb Boulevard and the south ridges need benched pads, stepped footings and retaining walls. We take off over-excavation, structural fill, drainage board and footing drains as separate line items so you can see the real earthwork cost.
Watch for: Over-excavation depth, shoring, retaining wall footing volume, footing drains
Repeated plans on graded lots in Clackamas County subdivisions. We build one detailed takeoff per plan and a lot-specific adjustment sheet for pad depth, driveway length, utility trenching and flatwork, which keeps your bid consistent across phases.
Watch for: Per-lot pad depth, driveway length, utility runs, flatwork square footage
Historic-core and McLoughlin corridor buildings bring selective demolition, structural retrofits, new MEP rough-in and exterior envelope work. Existing conditions mean more labor hours per square foot, and we carry allowances for concealed conditions you cannot see until walls open.
Watch for: Selective demo, structural upgrades, utility relocation, envelope repairs
Retail, office and mixed-use buildings along the main corridors. We take off shell and core separately from tenant improvements, price storefront glazing, and break out MEP by system so a landlord can compare base-building scope against tenant scope.
Watch for: Shell versus TI split, storefront glazing, MEP system breakdown
Detached ADUs and garages on existing residential lots, often on the same sloped ground as the main house. Small footprints still carry full trade coverage, so we take off foundation, framing, roofing, siding and MEP at the same detail level as a house.
Watch for: Utility trench distance, foundation type, roof tie-in, permit-driven life safety
Small warehouse, shop and contractor-yard buildings with slab-on-grade, pre-engineered or stick framing, and minimal finish. We price slab thickness, reinforcement, dock or grade-level doors and the electrical service as separate divisions.
Watch for: Slab thickness and reinforcement, door types, electrical service size
Two bids on the same drawings can differ by double digits here. These are the variables we price explicitly rather than assume away.
Oregon City and Clackamas County review building, site and utility permits, and hillside or creek-adjacent parcels can trigger geotechnical and drainage review beyond the standard set. Plan review comments can add design revisions and resubmittal time that show up in your schedule, not just your soft costs. Confirm the adopted code edition and any local amendments with the city building department before you lock a bid, and carry an allowance for review-driven changes.
Clackamas County · Oregon City building department · geotechnical reviewMuch of Oregon City is built on sloping ground above the Willamette and Clackamas rivers, and the soil profile changes quickly from lot to lot. Stepped footings, deeper stem walls, over-excavation and structural fill are common, and retaining walls may be needed for the pad, the driveway or both. We take off foundation and earthwork by actual geometry rather than a per-square-foot allowance, because on these lots the sitework can rival the house cost.
stepped footings · structural fill · retaining walls · footing drainsWillamette Valley winters bring long stretches of rain, which affects excavation, concrete placement, framing dry-in and exterior finishes. Dewatering, temporary erosion control, gravel working pads and covered storage are real line items on winter schedules. We note the weather-sensitive divisions in the takeoff so you can sequence them and price the protection measures instead of absorbing them.
dewatering · erosion control · concrete cure protection · temporary coversOregon City draws from the Portland metro labor pool, and the same crews also work Lake Oswego, Tualatin and the wider Clackamas County market. When residential and commercial work overlap, framing, concrete and MEP crews get tight and hourly rates move. We price labor with ZIP-code-adjusted data so your number reflects the local market rather than a national average.
Portland metro labor pool · framing crews · concrete crews · MEP tradesBluff lots, narrow downtown streets and parcels near the Willamette Falls area can limit where equipment, dumpsters and material deliveries go. Steep driveways may require crane or pump placement for concrete, and storm drainage often needs to tie into existing systems with limited fall. We add line items for access mats, pumping, traffic control and drainage runs when the site plan shows them.
limited access · concrete pumping · storm drainage tie-in · traffic controlConcrete, lumber, trusses and finishes come into Oregon City from suppliers across the Portland metro and Willamette Valley, so freight and lead times vary by product. Longer hauls and special orders add cost, and delivery windows can drive the schedule. Our pricing uses ZIP-code-adjusted material data, and we list long-lead items such as trusses, windows and electrical gear so you can order early.
ready-mix concrete · roof trusses · windows · electrical gearOregon City sits on the Clackamas River at the south edge of the Portland metro, and the takeoff reflects that: hillside lots, wet winters, and a permit mix that in 2025 was almost entirely single-family. Here is how those conditions land in the divisions.
Most Oregon City lots slope, so cut and fill is rarely a simple balance. We take off clearing by area, then strip topsoil at 6 to 8 in. depth and stockpile it separately because it usually comes back as finish grade. Structural fill is measured in compacted cubic yards, not loose, and we check the geotech report for the compaction spec before pricing haul. Export is the line that surprises people: when a site can't balance, every excess yard carries trucking and disposal. Erosion control blanket, silt fence, and a construction entrance with rock are separate bid items, not allowances. Our sitework estimating services break these out by phase so you can see which line drives the number.
Oregon City residential framing is mostly 2x6 walls with engineered floor systems, and the takeoff follows the plan set stud by stud. We count plates by wall length, studs at 16 in. on center with openings, headers, and blocking, then convert to board feet and pieces. I-joists are taken off by depth, span, and spacing from the floor framing plan, with rim board, hangers, and squash blocks listed separately. Roof framing on the hillside lots often runs to engineered trusses or a hybrid, so we price both when the drawings allow. Wall sheathing, house wrap, and flashing tape are Division 06 or 07 depending on how your spec is organized — we follow your format. Our framing estimating services page shows the takeoff sheet.
MEP takeoffs on Oregon City homes follow the fixture and device count first, then the distribution. We count plumbing fixtures, hose bibs, and floor drains, then measure supply and DWV runs by pipe size and material. For HVAC, we take off equipment by tonnage and AFUE or SEER rating from the mechanical schedule, then duct by linear foot and size, with boots, dampers, and registers as separate lines. Electrical is device count plus home runs: panel schedule, branch circuits by wire size, and a fixture count tied to the lighting plan. If the drawings lack a mechanical or electrical schedule, that is the first thing we flag. Our MEP estimating services page explains what we need to start.
Basement and crawlspace walls are common on the slopes above the river, and they change the concrete takeoff substantially. We measure wall forms by square foot of contact area, not by wall length, and add pilasters, window bucks, and bulkheads as separate items. Footings are taken off by linear foot with width and depth noted, then converted to cubic yards with a typical 5 to 10 percent waste factor. Slabs on grade get vapor barrier, capillary break, and mesh or fiber as distinct lines — these are frequent omissions. On stepped footings, count every drop; they are easy to miss on a plan review. See our concrete estimating services and foundation estimating services for how we structure these divisions.
Wet-season construction from October through April means roofing and weather barrier sequencing affects cost. We take off roof area by slope and pitch, then add for hips, valleys, and penetrations. Underlayment is measured by square (100 sq ft) with the manufacturer's required overlap, and ice-and-water membrane is listed by linear foot at eaves and valleys, not by roof square. On steep pitches, add labor for staging and fall protection. Ventilation — ridge vent, soffit vent, and any roof-to-wall flashing — belongs in the same takeoff so it doesn't get lost. Our roofing estimating services page covers the line structure we use for shingle, metal, and low-slope assemblies.
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 prices the footing and foundation wall concrete for a single-family home on a sloped lot in Oregon City. The dimensions are illustrative; your plan set will govern. We use cubic yards and a typical 5 to 10 percent waste factor on formed concrete.
Footing takeoff. The footing runs 160 linear feet around the perimeter, 12 in. wide by 24 in. deep. Volume per linear foot is 1.0 ft × 2.0 ft = 2.0 CF. Total volume is 160 × 2.0 = 320 CF. Divide by 27 to get cubic yards: 320 ÷ 27 = 11.85 CY. Add 8 percent waste: 11.85 × 1.08 = 12.80 CY, rounded to 13 CY.
Foundation wall takeoff. The wall is 8 in. thick and 9 ft high, running the same 160 LF. Volume per linear foot is 0.667 ft × 9.0 ft = 6.0 CF. Total is 160 × 6.0 = 960 CF. In cubic yards: 960 ÷ 27 = 35.56 CY. Add 8 percent waste: 35.56 × 1.08 = 38.40 CY, rounded to 39 CY.
Formwork. Wall forms are measured by contact area. Two faces at 9 ft high over 160 LF: 2 × 9 × 160 = 2,880 SF. Footing forms are 2 sides at 2 ft high over 160 LF: 2 × 2 × 160 = 640 SF. Total formwork is 3,520 SF.
Step footings. The lot slopes, so the footing steps down four times. Each step adds a vertical drop of 24 in. and a horizontal offset of 12 in. We add 4 × (2.0 × 1.0 × 1.0) = 8 CF, or 0.30 CY, plus formwork at 4 × (2 × 2 × 1) = 16 SF.
| Step | Calculation | Quantity | Unit |
|---|---|---|---|
| Footing volume | 160 LF × 2.0 CF/LF ÷ 27 × 1.08 | 13 | CY |
| Wall volume | 160 LF × 6.0 CF/LF ÷ 27 × 1.08 | 39 | CY |
| Wall formwork | 2 × 9 ft × 160 LF | 2,880 | SF |
| Footing formwork | 2 × 2 ft × 160 LF | 640 | SF |
| Step footings | 4 steps × 2.0 CF ÷ 27 × 1.08 | 0.30 | CY |
| Step formwork | 4 × 2 × 2 × 1 | 16 | SF |
What changes the number. A higher wall or a deeper footing on the downhill side adds concrete and formwork fast. If the geotech report calls for a drainage board or waterproofing, that is Division 07 and belongs in the same bid. Our foundation estimating services page shows how we present these lines in Excel, organized by CSI division with the plan markups attached.
Rain from October through April affects earthwork, concrete, and roofing most. We price erosion control, temporary cover, and dewatering as separate items rather than burying them in a general condition. On a sloped lot, wet soil can also mean more export because it won't compact. If your schedule pushes foundation work into winter, expect the concrete and sitework lines to carry a weather allowance. Confirm the current stormwater requirements with the city before you bid.
Send the complete plan set, including the architectural, structural, and any mechanical, electrical, and plumbing drawings. We also need the geotech report if you have it, the specification book, and any addenda. If the project is in Clackamas County, the permit set and plan review comments help us flag scope that changed after the original drawings. We return Excel and PDF takeoffs organized by CSI MasterFormat division with marked-up plan sets.
The numbers come from the U.S. Census Bureau's Building Permits Survey for 2025. They count new privately-owned residential units permitted by the city itself. In 2025, Oregon City issued 287 single-family units and no multifamily units, up from 23 units in 2024. The permitted value was $58M, averaging $203,500 per unit. The survey does not include commercial or industrial permits, so it is a residential indicator only.
Yes. We take off commercial and industrial projects using the same CSI MasterFormat structure, with divisions broken out by trade. On commercial work the MEP and sitework divisions usually carry the most risk, so we spend extra time on the mechanical schedule, panel schedules, and the civil drawings. If your project is a tenant improvement, send the base building drawings as well so we can separate new work from existing conditions. Our commercial estimating services page covers the deliverable.
We use ZIP-code-adjusted material and labor pricing, drawing on RSMeans data for the base rates and adjusting for the local market. Oregon City sits in the Portland metro labor shed, so rates reflect that market rather than a statewide average. We do not publish a single wage number because it varies by trade and crew size. If you have recent subcontractor quotes for the same scope, send them and we can compare our labor assumptions against them.
Most projects return in 24 to 48 hours. Larger commercial or multi-building projects take longer, and we will tell you the schedule before we start. Rush service is available if your bid date is close. We deliver Excel and PDF files organized by CSI MasterFormat division, with marked-up plan sets so you can trace every quantity back to the drawing.
Yes. Along with Oregon City, we cover Lake Oswego, Tualatin, Keizer, McMinnville, Grants Pass, and Redmond. The soil, slope, and jurisdiction rules change as you move, so we adjust the takeoff accordingly. If your project is in one of those cities, mention it when you send the plans and we will apply the right local pricing and code context.
We apply waste factors by material, not one blanket percentage. Framing lumber typically runs 5 to 10 percent, drywall 10 to 15 percent, roofing shingles 10 percent for hips and valleys, and concrete 5 to 10 percent on formed work. On sloped lots, cut-offs on framing and siding tend to run higher, so we note the assumption on the takeoff sheet. If your supplier has a standard return policy, tell us and we can adjust.
Yes, and we prefer to see the comments. Clackamas County review often changes foundation details, drainage, or egress requirements, and those changes move quantities. We take off the current set and mark the items that are likely to change if the comments are not yet resolved. That way you can bid with a clear picture of what is firm and what is still open.
We use Bluebeam Revu for plan markup and quantity review, PlanSwift for digital takeoff, and RSMeans data for material and labor pricing. The output is Excel and PDF organized by CSI MasterFormat division. If your team works in a different estimating platform, we can deliver the quantities in a format that imports cleanly. Send a sample of your preferred template with the plans.
Send your plan set and we will return a CSI-organized takeoff in 24 to 48 hours.
