How Much Does It Cost to Build a Deck in Kansas City, MO? [2025 Data]

There’s nothing quite like a summer spent grilling on the deck while the smell of BBQ drifts through the neighborhood. If you’re ready to turn your backyard into the next great hangout spot, knowing the cost to build a deck in Kansas City is the perfect place to start. On average, building a deck in the Heart of America runs about $8,039, with a majority landing between $4,367 and $12,028. 

Deck Building Cost Factors

Kansas City’s mix of clay-heavy soil and rolling terrain can significantly impact your final bill. Homes built on slopes or in areas like Brookside or Waldo may require additional foundation work or support posts to maintain the structure's stability. Meanwhile, those in North KC or Overland Park could pay more if drainage improvements or soil stabilization are needed before construction begins.

The weather is another big factor. Kansas City's hot, humid summers, icy winters, and year-round temperature swings can take a toll on certain deck materials. For instance, pressure-treated wood is affordable but needs regular sealing to withstand the freeze-thaw cycle and summer storms. 

Prices can increase significantly for multi-level designs, premium materials, or extras such as built-in seating and lighting. But once the work is complete, you'll have a space made for Chiefs watch parties, Boulevard beers, and those picture-perfect Midwest sunsets.

Size

Most new decks cost $29 to $58 per square foot. The higher end of that range represents deck projects built on second stories, building a deck with high-end wood, or customized designs. See the table below for general estimates based on the size of your deck:

Material

Your chosen deck material will make up a large portion of your total budget, ranging from $2 to $44 per square foot. Less-expensive materials can be tempting, but they may result in extra expenses for maintenance and repair, which you’ll need to hire a local deck contractor to handle. 

Here’s a breakdown of the materials and their costs:

• Pressure-treated wood costs $2 to $5 per square foot 

• Composite deck materials cost $12 to $21 per square foot 

• Ipe wood decking costs $10 to $19 per square foot 

• Tigerwood costs about $7 to $15 per square foot

• Mahogany costs $8 to $11 per square foot 

• Redwood decking costs $5 to $34 per square foot

• Bamboo decking costs $3 to $10 per square foot

• Cedar decking costs $3 to $7 per square foot 

Metal or aluminum decking costs $15 to $19 per square foot

Deck Type

Simply put, the more complex your deck build is, the more it will cost. Types of decks like wraparound, multi-tier, and rooftop decks require greater accessibility, additional prep work, and often more materials.

For example, if you want to build a floating deck, it will likely cost about $19 to $58 per square foot. These decks don’t actually float—they’re just not attached to your home. Because of this, they’ll need a few more support posts to keep them structurally sound.

Deck Height 

The type of deck you build will likely go hand in hand with where it’s installed. A second-story deck (which some contractors might deem a balcony) costs more to build because it’s harder to install. The most common place to install a deck, which is also likely the most cost-effective, is on the first floor attached to the backside of your home.

Here’s one example of how the cost average might differ:

• 10x10 first-story deck: $973–$1,946

• 10x10 second-story deck: $3,891–$4,864

Framing

Framing a deck, which ensures the unit's joints are structurally safe and sound, costs $9 to $12 per square foot for labor. The lumber or materials needed to frame your deck account for about one-third of the lumber you’ll need.

Flooring

Some homeowners choose to install flooring over a wood deck. Composite is a good material option, while more elegant choices like porcelain or ceramic could add thousands (or tens of thousands, depending on the deck’s size) to your price tag. The average cost ranges from $19 to $44 per square foot, depending on the material. 

Add-Ons

Here are some other costs you might incur if you upgrade from a simple deck build:

• Staircase cost: $24–$49 per stair

• Electricity cost: $126–$292 per outdoor outlet

• Outdoor lighting fixtures cost: $49–$486

• Heaters cost: $97–$292

• Outdoor misting system cost: $2,043–$3,308

• Sofa, chairs, and table cost: $486+

• Outdoor fireplace cost:$1,459–$7,782

• Retractable deck awning cost: $584–$3,405

Deck Pro Costs

When hiring a deck builder in Kansas City, local regulations, permits, and labor rates influence cost.

Local Labor Rates

In the City of Fountains, labor costs for deck work are refreshingly down-to-earth. The city's cost of living is around the national average, so local contractors don't charge coastal prices, but they're not working for peanuts, either. Expect to pay for skill and speed, not flash.

Permits

If you're planning to build anything other than a short background platform, you'll need a permit from the city. Anything attached to your house or exceeding 30 inches in height requires official approval.

You can apply online through the CompassKC Portal, and the fee depends on the value of your project, not a flat rate. If you’re wondering who to hire to build a deck, that’s when working with local contractors pays off. They know the ropes, not to mention the inspectors, and can help fast-track paperwork and sidestep rookie mistakes. Deck builders must hold a contractor's license for any job that needs a permit, and pros need a business license to operate legally within city limits.

Sales Tax on Materials

Missouri's combined sales tax rate in Kansas City is 8.86%, but it won't be on a separate line on your invoice like a restaurant tab. That's because contractors pay sales tax on materials when they buy them and incorporate them into their total. Homeowners generally do not pay tax on construction labor.

Tipping

While tipping your deck crew isn't required, it’s the best way to show appreciation when they've gone above and beyond. For small and less complex jobs, hand each crew member $10 to $20. Conversely, 10% to 20% of the total cost spells customer satisfaction for larger or fully tricked-out projects. Don't underestimate the tremendous value of leaving a glowing review on Angi or Google if a cash tip isn’t in your budget.

Does Building a Deck Increase Home Value?

Your future deck isn’t just another backyard project. It’s a Kansas City lifestyle upgrade that practically pays for itself. Homeowners may see up to an 83% ROI, adding roughly $3,620 to $10,450 in resale value. But the real value runs deeper than numbers.

In neighborhoods like Brookside, Waldo, and the Northland, a well-built deck becomes an everyday retreat. It’s where you sip coffee before the humidity sets in, unwind after work, or host  laid-back dinners when the weather’s too nice to stay inside. Details such as wide stairs, secure railings, and easy access for all ages make the space both practical and welcoming.

Buyers appreciate decks that feel safe, solid, and well-crafted, not like a quick DIY job waiting to tilt under a grill. When the design complements your home’s architecture and incorporates warm tones that evoke a Plaza sunset, it adds lasting appeal.
