Free guide, updated for 2026

The cost to build
in Southern Utah.

We pulled together the same 2026 pricing model we use to budget our own custom homes across Washington, Iron, and Kane counties, and wrote it down plainly. Real ranges, the things that move them, a sample budget, and where to save. No teaser numbers, no sales pitch.

At a glance, 2026

Build cost per square foot for a custom home in St. George and the surrounding Washington County market. Land, landscaping, and pools are quoted separately.

Premium finish

$385 per sq ft

Luxury finish

No-compromise, fully bespoke

$525+ per sq ft

What is inside

Six sections, no fluff.

01

Real 2026 cost ranges

Build cost per square foot for St. George, Ivins, Hurricane, Washington, Cedar City, and Kanab, separated by finish level so you are comparing like with like.

02

What actually drives the price

Why two homes the same size can be $400K apart: lot slope and sitework, finish allowances, structural complexity, and county impact and permit fees.

03

A sample line-item budget

A worked 4,500 sq ft budget broken out the way our contracts are, foundation through finals, so you can see where the money really goes.

04

Where you can save without regret

The choices that cut cost without showing up in five years, and the ones that look like savings but cost more later.

05

Soft costs people forget

Lot purchase, geotech and civil engineering, design review, landscaping, and pools, the line items that quietly blow up a budget.

06

Questions to ask any builder

A short checklist for reading a bid honestly, so teaser pricing and vague allowances cannot hide a number that grows after you sign.
