Adding a Second Story in Utah: Cost & Process Guide (2026)
May 13, 2026
In plain English
Adding a second story doubles your home's square footage without losing your yard — but it's the most complex addition you can do. Expect $400 to $700 per square foot in Utah for 2026.
Typical project costs
| Second story size | Typical cost |
|---|---|
| 600 sq ft | $240k – $420k |
| 1,000 sq ft | $400k – $700k |
| 1,500 sq ft | $600k – $1.05M |
| 2,000 sq ft | $800k – $1.4M |
Why it costs more than a ground-floor addition
| Cost driver | Why |
|---|---|
| Structural reinforcement | Existing walls/foundation must support new load |
| Temporary weather protection | Roof off for weeks during winter is risky |
| New stairwell | Eats first-floor space; framing + finish |
| HVAC redesign | Often need second zone or upgraded system |
| Engineering | Stamped structural plans always required |
| Disruption to existing home | Often need to live elsewhere for 4–6 months |
Can your home support a second story?
Critical factors:
| Factor | What to check |
|---|---|
| Foundation | Width, depth, soil bearing |
| First-floor walls | Stud spacing, sheathing, header sizing |
| Roof structure | Often fully removed and replaced |
| Plumbing stack | New stack route to second floor |
| Electrical service | May need 200A upgrade |
| HVAC capacity | Almost always needs upgrade |
The honest answer: most Utah homes built post-1985 can support a second story with $15k–$60k in structural reinforcement. Older homes can need $80k+.
Step-by-step process
| Phase | Duration | What happens |
|---|---|---|
| Feasibility study | 2–4 weeks | Engineer reviews structure |
| Architectural design | 8–14 weeks | Plans, elevations, layouts |
| Structural engineering | 4–8 weeks | Stamped calcs |
| Permits | 6–12 weeks | City review |
| Demo & reinforcement | 2–4 weeks | Foundation/wall work |
| Roof removal & framing | 2–6 weeks | Highest-risk phase |
| Mechanical rough-in | 3–5 weeks | Electric, plumbing, HVAC |
| Insulation, drywall | 3–4 weeks | Close walls |
| Finishes | 8–14 weeks | Floors, trim, paint, fixtures |

Cost by Utah city
| City | Per sq ft (mid-range) |
|---|---|
| Salt Lake City | $440 – $620 |

Living arrangements during build
Most clients move out for 4–6 months during the framing and roofing phases. After that, ground floor is usable but noisy.
| Strategy | Cost |
|---|---|
| Short-term rental | $3k – $6k/month |
| Stay with family | Free (but stressful) |
| Stay during build | Possible after weather-tight; brutal weeks 4–10 |
ROI
| Use case | Resale recovery |
|---|---|
| Adding bedrooms (3 → 5) | 70 – 85% |
| Adding master suite | 75 – 85% |
| Doubling living area | 65 – 80% |
| Park City premium home | 80 – 100%+ |
FAQ
How much does it cost to add a 1,000 sq ft second story?
$400,000 to $700,000 in Utah for 2026, depending on city and finishes.
Will I need to leave my home?
Yes, typically for 4–6 months during the demo, framing, and weather-in phases.
