How Much Does It Cost to Build a Deck in Phoenix? [2025 Data]

Phoenix has one of the hottest, sunniest climates of any city in the U.S. Inclement weather is rare, so outdoor living spaces like decks are common on Phoenix homes. It costs $4,566 to build a deck in Phoenix on average, with total costs ranging from $1,794 to $7,512. This guide details factors affecting the cost to build a deck in Phoenix.

Deck Building Cost Factors

Specific decking materials work better in Arizona’s warm desert climate, impacting the average decking project cost in the Phoenix metro area. Other cost factors include deck size, type, height, framing, flooring, and add-ons. Let's explore each of these factors in detail.

Size

Most new decks in Phoenix cost $15 to $30 per square foot, although costs can get as high as $60 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 $45 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. This is especially true in Phoenix, where intense sunlight can dry, crack, and discolor certain materials more quickly than others.

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 $22 per square foot 

• Ipe wood decking costs $10 to $20 per square foot 

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

• Mahogany costs $8 to $11 per square foot 

• Redwood decking costs $5 and $35 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 $20 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 $20 to $60 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. If possible, the most practical place to add a deck to a Phoenix home is the north side of the house. This helps avoid direct afternoon sunlight.

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: $1,000–$2,000

• 10x10 second-story deck: $4,000–$5,000

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 $20 to $45 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: $25–$50 per stair

• Electricity cost: $130–$300 per outdoor outlet

• Outdoor lighting fixtures cost: $50–$500

• Heaters cost: $100–$300

• Outdoor misting system cost: $2,100–$3,400

• Sofa, chairs, and table cost: $500+

• Outdoor fireplace cost: $1,500–$8,000

• Retractable deck awning cost: $600–$3,500

• Pergolas, ramadas, or other shade structures: $2,100–$6,400

Deck Pro Costs

When hiring a deck pro in Phoenix, ensure the contractor you hire is licensed with the state of Arizona. Any additions to your home require a license to construct. You can verify a license with the Arizona Registrar of Contractors. Hiring a deck builder in Phoenix comes with a few additional costs.

Building Permit Fees

Decks and other outdoor upgrades require a building permit in Arizona. You or your hired deck builder must obtain this permit from your local jurisdiction's building department. Your building permit fee is based on the valuation and square footage of the deck being built. Expect a minimum fee of $160, but fees can reach $320 or more.

Taxes

Arizona also imposes a Transaction Privilege Tax on contractors for any materials used in a decking project. This cost usually gets passed onto the homeowner and may be lumped in with total material or project costs, making materials seem more expensive than if you purchased them for a DIY project.

Does Building a Deck Increase Home Value?

Adding a wooden deck to your Phoenix, AZ home can deliver an average 90% return on investment (ROI). Decks are desirable in Phoenix because they take advantage of outdoor views better than windows.

If your deck features a shade structure like an awning, pergola, or ramada to shield it from the intense heat of the desert sun, expect the deck to add even more value and attract more attention from potential buyers when selling your home.
