If you're thinking about building a deck in Idaho, you're probably wondering what you're going to drop on it. I've been helping homeowners across the state figure out their deck budgets for years, and honestly, the costs vary more than people expect. So let me break down what you're actually looking at in 2025.
The thing about deck pricing in Idaho is that it depends on a bunch of factors—materials, size, complexity, and where you live. A basic deck in Boise might cost differently than one in Idaho Falls, simply because of local labor rates and material availability. Let's get into the real numbers.
In Boise, you're looking at somewhere between $4,500 and $15,000 for a standard 12x16 foot deck. That's probably the most common size people go with, and prices tend to be on the higher end here since Boise has a competitive market and higher labor costs. If you want something fancier with composite materials, add another $2,000 to $5,000 to that estimate.
Meridian is right next to Boise, and prices are pretty similar. You'll spend around $4,200 to $14,000 for that same-sized deck. Labor here is competitive, but material costs are basically the same across the Treasure Valley.
Nampa tends to be slightly cheaper than Boise and Meridian. Expect to budget $3,800 to $12,500 for a 12x16 deck. You might save a bit on labor, but the savings aren't huge—we're talking a few hundred dollars in most cases.
Idaho Falls is where pricing gets interesting. It's further from the major suppliers, which sometimes pushes material costs up. For the same deck size, plan on $4,000 to $13,500. Winter weather is harsher there too, which affects construction timelines and can impact your final bill.
Material choice is the biggest factor. Pressure-treated lumber is your budget option—you're looking at roughly $15 to $25 per square foot for the finished deck. It's durable, holds up well in Idaho's climate, and requires regular maintenance.
Cedar or redwood will run you $25 to $40 per square foot. It looks better, smells amazing, and ages nicely, but you'll need to stain it every few years.
Composite decking (like Trex or Fiberon) is the premium choice at $35 to $60 per square foot. It doesn't rot, doesn't splinter, and requires almost zero maintenance. A lot of homeowners in Idaho are going this route now, and I get it—the longevity pays off.
Then you've got labor, which typically runs $50 to $85 per hour depending on your contractor and location. Most decks take 40 to 80 hours to build, so you're looking at $2,000 to $6,800 just in labor for a standard size.
Complexity matters too. A simple ground-level deck is cheaper than one that's elevated. Adding stairs, railings, built-in benches, or lighting fixtures all increase the cost. A deck with a pergola or shade structure will cost significantly more—we're talking an extra $2,000 to $4,000.
Here's something a lot of people don't think about: Idaho's seasons affect deck costs. Spring and summer are peak season, and contractors charge a premium. If you can wait until fall, you might save 10 to 15 percent. Winter is cheapest, but good luck getting quality contractors available, and cold weather makes construction slower and more complicated.
Permits and inspections in Idaho typically run $100 to $500, depending on your city. Boise and Meridian are on the higher end, while smaller cities might be cheaper. Some contractors include this in their bid, others don't, so ask.
If you're trying to keep costs down, start with pressure-treated lumber. You'll save money upfront, even if you need to refinish it down the road. A 12x16 basic deck can come in under $5,000 if you keep the design simple.
Get at least three quotes from local contractors. I'm not saying go with the cheapest—sometimes you get what you pay for—but comparing prices gives you a realistic picture of what your deck should cost.
Consider building in phases. Start with the basic platform and railings, then add stairs or a pergola later. This spreads out the expense and lets you enjoy your deck sooner.
Also, think about your long-term plans. If you're planning to sell your house in five years, composite decking might be worth the investment. If you're staying put for 20 years, composite almost always wins financially.
A 12x12 or 12x16 deck works for most homeowners. That gives you enough room for a table and chairs without overwhelming your yard. Bigger decks cost more but might be worth it if you entertain often.
Pressure-treated decks typically last 15 to 20 years with proper maintenance. Composite lasts 20 to 30 years. Idaho's sun and occasional snow aren't too harsh compared to other regions, so your deck should hold up well.
Most cities in Idaho require permits for decks. It's not worth skipping—inspectors make sure your deck is safe, and unpermitted work can complicate selling your home later.
