What's a realistic per-square-foot build cost right now?

Why one number hides everything

Cost per square foot moves with your site, your plan complexity and your finish level. Two houses of the same size on the same street can differ by a third, and a quote expressed as one number per foot is usually hiding which one you are getting.

It is a useful shorthand between builders. It is a poor basis for a homeowner decision.

Ask for the line items instead

A real budget separates the work into trades and then calls out the allowances. Five allowances account for most overruns:

• Cabinets.
• Tile.
• Plumbing fixtures.
• Lighting.
• Flooring.

An allowance is a placeholder, not a price. If it is set low the budget looks attractive and the overrun arrives at selection time, which is the oldest trick in residential construction and usually not even deliberate.

Keep site costs out of the per-foot conversation

Clearing, fill, septic, a long driveway and any retaining work are properties of the lot rather than the house. Mixing them into a per-foot figure makes a difficult site look like an expensive house, and an easy site look like a bargain builder.

Permits and impact fees sit on top of all of it. Ask the county what they will be for your parcel rather than accepting an estimate.

How to compare two builders honestly

1. 1Give both the same plan and the same written specification.
2. 2Ask both for the same allowance list, with the same quantities.
3. 3Ask what is excluded. The exclusions list tells you more than the total.
4. 4Ask how change orders are priced and who signs them.

Before any of this, the lot has to be right: what to check before buying a lot. If you are choosing between a production builder and a custom build, how much you can change a builder plan frames the trade-off.

Where budgets move after signing

• Selections above the allowance, which is the most common and the most avoidable.
• Site conditions found after clearing, which is why the soil boring matters before closing.
• Change orders during framing, because a decision made on paper costs a fraction of the same decision on site.
• Delays, which cost money in extended financing rather than in materials.

The defence against all four is the same: a written specification, allowances you have actually shopped, and a change-order process agreed before the first inspection.
