“How much does a deck cost?” is the first question almost every homeowner asks us — and it’s a fair one. The honest answer is that no two decks cost the same, because size, material, site conditions, and railing choices all move the number. But you shouldn’t have to book an estimate just to know the ballpark. Here’s how deck pricing actually works in the Salem-Keizer area in 2026, using published market data, so you can budget with your eyes open.
The short answer: what market data says decks cost in 2026
National 2026 cost guides (sources like Decks.com and Ergeon’s installed-price data) put professionally built decks in these ranges, materials and labor included:
- Pressure-treated lumber: roughly $25–$40 per square foot installed. The budget workhorse — strong and code-compliant, but it needs regular sealing to look good in Oregon’s climate.
- Cedar: roughly $30–$50 per square foot installed. The classic Northwest choice — naturally rot-resistant and beautiful, with moderate upkeep.
- Composite: roughly $35–$55 per square foot installed for mid-grade boards, and $50–$70+ for premium lines. Highest upfront cost, lowest maintenance — no staining, no sealing, no rot.
To put that in real terms: a 300-square-foot cedar deck lands somewhere around $9,000–$15,000 at national market rates, while the same footprint in mid-grade composite runs roughly $10,500–$16,500. Local pricing in the Willamette Valley can sit above or below national medians depending on the season, site access, and material availability — which is why a written, site-specific quote matters more than any chart.
Important: these are published market ranges, not Stronghold’s prices. Our quotes are based on your actual yard, your material choices, and your design — in writing, with no surprise add-ons.
The five things that move your deck price the most
1. Size — but not the way you’d think. Bigger decks cost more in total but often less per square foot, because setup, footings, and permitting get spread across more deck. A slightly larger deck is frequently the better value per foot.
2. Material choice. As the ranges above show, the jump from pressure-treated to premium composite can nearly double the per-foot price. The right call depends on how long you’ll be in the home and how much maintenance you want to own. We broke this down in detail in our guide to composite vs. wood decking in Salem and Keizer.
3. Height and site conditions. A ground-level deck on flat, accessible ground is the simplest build. Elevated decks need engineered footings, stairs, and guardrails; sloped yards and tight access add labor. This is usually the biggest surprise factor in a quote.
4. Railings. Railing is priced by the linear foot on top of the deck itself, and the spread is wide — basic wood balusters on the low end, cable or glass panel systems at a premium. On an elevated deck, railing is required by code, so it belongs in your budget from day one. See what we install on our deck railing page.
5. Extras that turn a deck into a living space. Built-in benches, lighting, pergolas and covered sections each add real money — and real value. Most of our Salem and Keizer customers phase these: build the deck now, add the cover next season.
Do you need a permit for a deck in Salem or Keizer?
Often, yes. Under Oregon’s residential code, a freestanding deck no more than 30 inches above grade is generally exempt from a building permit — but attached decks and anything taller typically need one, and railing and stair requirements kick in with height. Permit fees are set by the city and scale with project valuation; 2026 permit guides put typical residential deck permit fees in Oregon in the few-hundred-dollar range, and the City of Salem publishes its own fee schedule and review process.
Here’s the part that matters for your budget: we handle the permits. Application, drawings, HOA submissions, inspections — that’s included in how we run every project, so the paperwork never lands on you. It’s one of the details that separates a professional build from a headache.
Why cheap bids in the Salem area often cost more later
If you collect three bids and one is dramatically lower, look at what’s behind the number. Common corners that get cut: wood posts set directly in soil instead of proper footings, undersized joists, no flashing at the ledger board (the #1 cause of deck failure and rot), and no permit — which becomes your problem when you sell the house. Oregon’s wet winters punish shortcuts faster than almost any climate in the country. A deck built right the first time is cheaper than a deck built twice.
Every deck we build is permitted, inspected, and backed by a lifetime workmanship warranty — if something fails because of how it was installed, we come back and fix it. That warranty only means something because of how we build: proper footings, flashed ledgers, quality fasteners, and materials chosen for this climate.
