Deck Building Cost Factors

The cost of building a deck in Austin, TX, can depend on the size, material, and any additional features chosen. Here’s how these factors will affect your deck-building cost.

Size

Most new decks cost $30 to $50 per square foot. The higher end of that range represents deck projects built on second stories, utilizing 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 comprise a significant portion of your total budget, ranging from $2 to $40 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 $4 per square foot 

• Composite deck materials cost $11 to $20 per square foot 

• Ipe wood decking costs $9 to $18 per square foot 

• Tigerwood costs about $6 to $13 per square foot

• Mahogany costs $7 to $10 per square foot 

• Redwood decking costs $4 to $31 per square foot

• Bamboo decking costs $3 to $9 per square foot

• Cedar decking costs $3 to $6 per square foot 

• Metal or aluminum decking costs $13 to $18 per square foot

The weather in Austin, TX, is hot and humid for much of the year. The type of deck material you choose can significantly impact the structure's lifespan. Here are the pros and cons of the most popular deck materials for an Austin home.

Deck Type

Simply put, the more complex your deck build is, the higher the cost will be. Some 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 $18 to $53 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 be determined by 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: $890–$1,780

• 10x10 second-story deck: $3,560–$4,450

Framing

Framing a deck, which ensures the unit's joints are structurally safe and sound, costs $8 to $11 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 $18 to $40 per square foot, depending on the type of material chosen. 

Add-Ons

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

• Staircase cost: $20–$50 per stair

• Electricity cost: $120–$270 per outdoor outlet

• Outdoor lighting fixtures cost: $40–$450

• Heaters cost: $90–$270

• Outdoor misting system cost: $1,870–$3,030

• Sofa, chairs, and table cost: $450+

• Outdoor fireplace cost: $1,340–$7,120

• Retractable deck awning cost: $530–$3,120

Deck Pro Costs

Hiring a deck builder in Austin, TX, is the best way to ensure the finished structure is safe and usable. Here’s what you should know about the cost of hiring a pro.

Labor

The cost of living in Austin is approximately 3% lower than the national average, meaning labor costs can be more affordable. Generally, contractors and other professionals who build decks charge between $13 and $31 per square foot. However, the price you pay can also depend on where in the city you live and your chosen contractor's expertise level.

Permits

The City of Austin requires you to obtain a permit before you build a deck. The price of the permit can depend on whether or not the deck is attached to your home. The city considers attached decks additions to your home and will price the permit depending on the deck’s square footage. Depending on your location, you may also need to have your project reviewed by the city before proceeding. If you’re unsure about your project's permitting requirements, ask your contractor for advice or contact the city directly.

Insurance

When you build a new deck on your property, you must let your homeowners' insurance provider know. Attached decks should be covered under your policy’s dwelling coverage, while unattached decks will need other structures coverage. Adding a deck to your home may increase your insurance premiums because of the added liability.

Taxes

The combined sales tax rate in the City of Austin is 8.25%. When determining your budget for your deck project, ensure you account for taxes on materials and labor. Ask your pro for an itemized estimate to see how much you’re paying in taxes.

Does Building a Deck Increase Home Value?

Building a deck can increase your home’s value by providing potential buyers with additional living space to enjoy. According to the Journal of Light Construction’s 2025 Cost vs. Value Report, building a wood deck in Austin has a return on investment (ROI) of 93.9%, while composite decks have an ROI of 85.8%. 

What does that look like with a real-life example? If your deck project costs $7,500, your home’s value could increase by $6,435 to $7,043. Of course, there’s never a guarantee that a project will increase your home’s value. However, a well-maintained deck can be a huge selling point—especially in a competitive real estate market.
