How much does a home addition cost in Utah?
A home addition in Utah typically runs about $224,000, with most projects landing between $189,000 and $314,000. Where you land comes down to the finish you choose, how hard your site is to work in, and where in the state you build.
What decides your number
Two addition projects the same size can land thousands apart. Three things move the total more than anything else, and the first one does most of the work.
TradesMetrics prices every job at one of four finish levels. This single choice is what stretches the range above from $189,000 to $314,000.
Basic
$189–223kStandard
$205–242kPremium
$234–276kLuxury
$267–314k2 · Site access
An easy ground-floor addition with parking is cheaper to work in than a tight upper-floor space with stairs and no loading. Difficult access adds labor hours for moving materials and debris.
3 · Where in UT
Local trade wages and material costs set the baseline, and Utah's larger metros run higher than its smaller cities. The same addition costs more in Salt Lake City, West Valley City or West Jordan than in Provo, Orem, Sandy or other cities in UT.
Where the money goes
Here is a standard-finish, normal-access Utah addition. Ballpark figures for planning, not a line-item quote.
| Category | Share | Cost |
|---|---|---|
| Cabinetry | 0% | $400 |
| Plumbing & electrical | 13% | $24,000 |
| Flooring, paint & finishes | 9% | $16,900 |
| Labor (install + trades) | 77% | $144,100 |
| Appliances | 1% | $1,500 |
| Total cost of work | 100% | $186,900 |
That $186,900 is what the work costs, before your markup and a contingency reserve. Here is how it becomes the price a client pays.
Markup is not margin
Here is that same $186,900 priced the way you bid it: each cost type marked up, plus a 10% contingency. What you keep is smaller than the markup looks, and that gap is where bids lose money.
| Cost element | Your cost | Markup | Client price |
|---|---|---|---|
| Labor (own crew) | $7,900 | 40% | $11,100 |
| Materials | $39,600 | 10% | $43,600 |
| Equipment | $17,300 | 10% | $19,000 |
| Subcontractors | $92,700 | 10% | $102,000 |
| Permits & fees | $29,400 | 0% | $29,400 |
| Contingency (10% reserve) | $18,700 | 0% | $18,700 |
| Total | $205,600 | +$18,200 | $223,800 |
- Total cost: $205,600
- Price to client: $223,800
- Profit: $223,800 − $205,600 = $18,200
- Markup = profit ÷ cost = $18,200 ÷ $205,600 = 9%
- Margin = profit ÷ price = $18,200 ÷ $223,800 = 8%
Same $18,200, two different numbers. You put 40% on your own labor, but it is a small slice; subs and materials carry only 10% and dominate the job, so the blend lands at 9% markup and just 8% margin. Inside TradesMetrics you set these per cost type and watch the margin move as the job changes.

- How much does a home addition cost in Utah in 2026?
- Most Utah addition builds run between $189,000 and $314,000, with a typical project around $224,000. An entry-finish, full-scope build comes in lower, while a luxury custom build with layout changes runs higher.
- What is the difference between basic, standard, premium and luxury?
- Basic is a full-scope addition build at entry finish: budget materials and standard fixtures, same layout. Standard steps up to mid-range materials and finishes with minor changes. Premium is semi-custom with high-end finishes and some layout change. Luxury is full custom: reworked layout and top-tier materials throughout.
- How much does a home addition cost per square foot?
- A full addition build typically runs about $410 to $480 per square foot at a standard finish, more for premium and luxury.
- Why does the price vary so much?
- For a Utah addition, finish level is the biggest driver, then site access and where in the state you build. Trade wages vary by region, and larger metros run higher than smaller cities.
- Is this an estimate or a quote?
- It is an estimate: a planning range built from regional cost data and your finish level. A quote is a firm price a contractor gives after seeing the site and final selections. Use the estimate to set a budget, then get a quote to lock it in.
- How much should I budget for surprises?
- Add a 10 to 20 percent contingency on top of the estimate for hidden conditions like outdated wiring or plumbing found once the work opens up.
- What is the difference between markup and margin?
- On a standard addition priced with TradesMetrics default markups, plus a 10 percent contingency reserve, the job costs you $205,600 and the client pays $223,800. That $18,200 difference is a 9 percent markup over cost but only an 8 percent margin of the price, because the low-markup subs and materials dominate the job.
- What is the real cost of labor on a job?
- Base wage is not the real cost. Once you add payroll taxes, workers comp, benefits and paid time off, a worker costs 35 to 50 percent more than their hourly wage. Estimating off base wage is a common way to lose money.
