How Much Does It Cost to Build a Deck in Sioux Falls?

If you’re thinking about adding a deck to your home in Sioux Falls, you’re not alone. Decks are one of the most popular outdoor upgrades for homeowners in the area, offering a perfect spot to relax, entertain, or enjoy the outdoors. But how much does it cost to build a deck in Sioux Falls? Let’s break it down.


Cost Breakdown: Average Prices in Sioux Falls

The cost to build a deck in Sioux Falls can vary widely depending on the size, materials, and complexity of the design. On average, homeowners can expect to pay between $60 and $120 per square foot for a professionally built deck.

Key cost factors include:

  • Material choice: Pressure-treated lumber is the most affordable option, while composite and Trex decking tend to cost more upfront but offer lower maintenance over time.
  • Deck size: Larger decks naturally increase total costs.
  • Labor: Expect higher labor costs for complex designs, multi-level decks, or when additional site preparation is needed.
  • Permits: In Sioux Falls, a building permit is typically required for deck construction. Fees vary based on deck size and scope.

Example cost ranges:

  • 12×16 pressure-treated wood deck: $5,000 – $8,000
  • 12×16 composite or Trex deck: $8,500 – $12,000

Popular Deck Materials Explained

Choosing the right material is one of the biggest decisions in the deck-building process. Here are the most common options:

Pressure-Treated Wood

  • Most affordable
  • Requires regular sealing or staining
  • Susceptible to rot and insect damage over time

Cedar or Redwood

  • Natural resistance to decay
  • More expensive than treated lumber
  • Needs regular maintenance to maintain appearance

Composite Decking (including Trex)

  • Made from recycled materials and wood fibers
  • Low maintenance (no staining or sealing)
  • Higher upfront cost but longer lifespan
  • Available in a wide range of colors and finishes

Many Sioux Falls homeowners are turning to composite or Trex decking for their durability, clean look, and minimal maintenance requirements.


Custom Features That Affect Cost

Adding personalized features can make your deck truly one of a kind—but it also affects the budget. Here are some popular upgrades:

  • Multi-level decks
  • Built-in seating or planter boxes
  • Pergolas or shade structures
  • Railing options (metal, cable, glass, etc.)
  • Integrated lighting or electrical
  • Deck skirting for a finished look
  • Waterproofing and drainage systems (especially for elevated decks)

Each of these features can enhance functionality and aesthetics, but they come with added cost. It’s best to prioritize based on your lifestyle and how you plan to use the space.
