Single-Family Home Estimating and Takeoff Services
We estimate custom homes, production housing and spec builds — from a foundation-only takeoff to a full multi-trade estimate with general conditions carried. Quantities come back organized by division, with allowances listed separately and their basis stated, because allowances are where residential budgets actually break.

Foundation. Slab-on-grade, crawlspace, basement or pier, with excavation, footings, walls, waterproofing and backfill quantified by condition rather than lumped into one number.
Framing package. Studs, plates, headers, joists, rafters or trusses, sheathing, blocking, hangers and connectors — in board feet for the buy and piece counts for the labor.
Envelope. Roofing by square, siding or masonry veneer by area, windows and doors by unit, plus house wrap, flashing and insulation by R-value.
Interior finishes by tier. This is where single-family estimates diverge most. A builder-grade and a custom finish package can differ by a factor of three on identical square footage, so finishes are quantified and priced by specified tier rather than a blended allowance.
MEP rough and trim. Fixture counts, panel and circuit counts, HVAC equipment and duct runs, with the rough-in and trim stages separated because they are bought and scheduled apart.
Site. Driveway, walks, grading, utilities from the street and landscaping where in scope — the scope most often left out of a residential budget entirely.
What Drives Cost in Single-Family Work
Site conditions. Slope, soil, rock, and how far utilities have to run. Two identical houses on different lots are not the same job, and site is where budgets break most often — because the house is designed before the lot is fully understood.
Custom versus production. Repetition is the single largest cost lever in residential. A production plan built forty times prices differently from a one-off, and not by a percentage — the framing crew, the material order and the supervision all change.
Finish tier. The largest swing factor after site, and the one clients most often change after the budget is set. Quantities barely move; the cost of the same square footage can multiply.
Allowances. Underset allowances are the most common failure in single-family estimating — cabinets, appliances, fixtures and flooring get a round number early and blow it later. We price allowances against the actual specification where one exists, and flag them explicitly where it does not.
Local code and climate. Frost depth, wind and seismic requirements, and energy code all vary by market and all move the framing and envelope numbers. A plan priced for one state is not priced for another.
Builder-supplied versus subcontracted. Which scopes you self-perform changes both the number and where the risk sits. We quantify the whole house and mark the boundary you tell us, rather than assuming a delivery model.
How We Handle Allowances
Allowances deserve their own section on a residential page, because they are the line items that turn an accepted budget into a change order.
Every allowance is listed, never absorbed. Allowances go on their own schedule with the scope each one covers. An allowance buried inside a division total is indistinguishable from a measured quantity, which means nobody knows which parts of the budget are firm.
Priced against the specification where one exists. If the drawings name a cabinet line, an appliance package or a flooring product, that is what gets priced. A round number is only appropriate where the selection genuinely has not been made.
The basis is written down. For every allowance, what it assumes — grade, quantity, and whether installation is included. A cabinet allowance that covers boxes but not counters, or material but not labor, is the classic source of a mid-build argument.
Flagged where the client is likely to change their mind. Finishes, fixtures and appliances get selected late and upgraded often. Identifying which allowances are most exposed lets you set expectations before the budget is signed rather than after.
Separated from contingency. An allowance covers a known scope with an unknown selection. Contingency covers the unknown itself. Merging them hides both, and the merged figure is always spent.
Who We Work With
Custom home builders
One-off houses where the finish specification and the site both carry real risk, and the allowance schedule matters more than the framing count.
Production builders
Repeated plans where getting the repetition priced properly — rather than multiplying a one-off — is the whole exercise.
General contractors carrying residential
Commercial GCs taking on housing, who need residential-specific assumptions rather than a commercial template applied to a house.
Developers and owner-builders
Testing lot feasibility before design, or acting as their own GC and needing a number nobody else has an interest in shaping.
What You Receive

- A marked-up plan set showing every measurement
- An assumptions and exclusions schedule
- Allowances listed separately, each with its basis stated
- Finish quantities segregated by specified tier
- Site scope as its own division, not folded into the house
Trades Involved in a House
A single-family estimate touches most of these. Each links to exactly what we quantify for that scope and in which units.
What We Need From You
A stock plan is usually enough for a solid number. The items below are what close the gaps we would otherwise have to assume.
- The house plans — floor plans, elevations, sections and any details
- The finish specification or selection sheet, which decides the finish tier
- The lot survey or site plan, including slope and utility locations
- Any soils or geotechnical information, where the foundation design depends on it
- Window, door and cabinet schedules if they exist
- Which scopes you self-perform versus subcontract
- The market — county or ZIP — so labor and material are priced locally
- Whether you want a full estimate or quantities only
Why Residential Estimates Come In Wrong
Cost per square foot applied to a specific house. A dollar-per-square-foot figure is an average of houses that are not yours, on lots that are not yours, at a finish tier nobody specified. It is useful for a sanity check and misleading as a budget, and it is how most residential overruns begin.
Allowances set before selections exist. A round number for cabinets, appliances, fixtures and flooring, agreed early and never revisited. The quantities were never wrong; the selections simply arrived later and cost more than the placeholder.
Site scope treated as an afterthought. Driveway, grading, utility runs from the street and landscaping are frequently absent from a house budget entirely, because the plans are about the building. On a difficult lot this is the single largest omission available.
Foundation priced from the plan, not the lot. A stock plan usually carries a generic foundation. Slope, soil bearing, frost depth and required over-excavation are lot-specific, and they change footing sizes, wall heights and backfill volumes together.
Repetition priced by multiplication. Forty units of a production plan do not cost forty times one unit. Material buying, crew learning and supervision all change, and treating production work as a multiple of custom work misprices it in the expensive direction.
Code and climate assumed from another market. Frost depth, wind uplift, seismic detailing and energy code all vary. A plan priced accurately for one state and reused in another is wrong in the framing and envelope before anyone has measured anything.

Tools and Standards
Quantities, rates and assemblies are read against the published references that govern this work. Where a project specification conflicts with any general reference, the specification governs:
- International Residential Code (IRC), to the edition adopted locally
- Local amendments for frost depth, wind and seismic design category
- IECC or the state energy code, where it governs envelope and insulation
- APA and NHLA standards for panel products and lumber grading
- AWI grades where architectural millwork is specified
- Manufacturer published coverage rates for roofing, insulation and coatings
- The project's own specification and selection sheet, which govern the finish tier
Frequently Asked Questions
Do you estimate custom homes or only production?
Both. Custom work needs more allowance detail; production work benefits from repetition being priced properly rather than multiplied.
Can you estimate from a stock plan?
Yes. Stock plans are usually complete enough for a solid estimate, though they often lack a site-specific foundation design — we will flag what is assumed.
How do you handle allowances?
Priced against the actual specification where one exists, flagged explicitly where it does not, and listed on their own schedule so you can see every one and what it assumes.
Do you work for homeowners?
We work with builders, contractors and developers. If you are an owner-builder acting as your own GC, yes.
Can you price a house that hasn't been designed yet?
Only as an order-of-magnitude budget from a program or a comparable. That is preliminary and budget estimating, and it should be presented as a range rather than a number.
Is site work included in the estimate?
It is quantified as its own division — driveway, walks, grading, utilities from the street and landscaping where in scope. It is reported separately precisely because it is the scope most often missing from a residential budget.
Can you price the same plan for several different markets?
Yes, and it is a common request for production builders. The quantities are measured once; labor, material and code-driven envelope requirements are then applied per market, so you can see what the same house costs in each.
Do you estimate the foundation separately?
If that is all you need, yes — a foundation-only takeoff is a common single-scope request, especially when the lot is difficult and the rest of the house is a known quantity.
