A deck is one of the best ways to extend your living space and add real value to your home. Utah's climate — with warm summers and beautiful mountain views — makes outdoor living worth every penny. But before you start planning, you need a realistic sense of what it's going to cost.
Average Deck Costs in Utah
In Utah County and the surrounding area, here's what most homeowners spend:
- Pressure-treated wood deck: $15–$25 per square foot
- Cedar or redwood deck: $25–$40 per square foot
- Composite deck (Trex, TimberTech): $35–$60 per square foot
- Covered patio or pergola addition: Add $5,000–$15,000 depending on scope
So a 400 sq ft deck — a comfortable size for most families — will typically run between $6,000 and $24,000 depending on materials and features.
What Drives the Cost Up or Down?
- Material choice — Pressure-treated wood is the most affordable upfront. Composite costs more initially but requires almost no maintenance and lasts longer.
- Height and complexity — A ground-level deck is simpler and cheaper than a second-story deck, which requires more structural work and often a permit.
- Railings — Basic wood railings are affordable. Cable railings or glass panels add significant cost but look stunning.
- Steps and stairs — Multiple stair runs add labor and materials.
- Built-in features — Benches, planters, lighting, or a pergola all add to the total.
Composite vs. Wood — Which Is Right for You?
This is the most common question we get. Here's the honest answer:
- Wood is cheaper upfront but requires sealing or staining every 1–3 years to prevent warping and fading in Utah's sun.
- Composite costs more upfront but is virtually maintenance-free, won't splinter, and holds its color for decades.
If you plan to stay in your home long-term, composite often wins on total cost of ownership. If budget is tight right now, quality pressure-treated wood is a perfectly solid choice.
Do You Need a Permit for a Deck in Utah?
In most Utah cities, yes — if your deck is over 30 inches off the ground or over a certain square footage, a permit is required. This varies by city, so it's worth checking with your local building department. A licensed contractor like Fisher Woods Construction will handle the permitting process for you.
How to Get the Best Value on Your Deck
- Get multiple bids and compare them line by line
- Don't skip the permit — it protects you when you sell
- Think about long-term maintenance when choosing materials
- Plan for lighting early — it's much cheaper to rough it in during construction
