Factors Affecting the Cost of Building a Deck

The price of your deck will vary based on several important factors. These include the size, materials used, and any additional features you want to incorporate.

Deck size

Deck size significantly impacts the total cost of building a deck. Building a 20×20 deck can set you back approximately $20,000. On the other hand, constructing a smaller deck like a 16×16 might cost around $12,800.

The average price per square foot ranges from $20 to $60 for most decks.

Ground-level decks are generally more affordable at about $10 to $20 per square foot. Always consider how much space your family needs and what fits within your budget. Larger decks offer more room but come with higher material and labor costs.

Deck materials

Choosing the right deck materials impacts both upfront costs and long-term maintenance. Decking material cost can range from $5 to $50 per square foot, with composite deck materials costing around $4 to $12 per square foot.

Cedar decking tends to be pricier, usually between $20 and $30 per square foot. For a more budget-friendly option, pressure-treated wood can cost anywhere from $15 to $25 per square foot.

Composite decking remains popular due to its low maintenance needs and durability. Natural wood options like cedar are valued for their aesthetic appeal but require more upkeep over time.

Each material offers unique benefits that cater to different priorities such as cost, appearance, and longevity.

Deck features

Adding features to your deck can have a significant impact on the final cost. If you include stairs, expect to pay between $160 and $560 for 8-16 steps. Composite decking, known for its durability and low maintenance, ranges from $30 to $80 per square foot once installed.

For those with pools, incorporating a pool deck costs approximately $30 to $60 per square foot.

Lighting fixtures enhance safety and ambiance but add extra expenses. Built-in seating or planters create comfortable spaces but require more materials and labor. Features like pergolas or shade structures also increase costs but provide valuable outdoor living space enhancements.

Labor costs

Labor costs can significantly impact the overall expense of building a new deck. Expect to pay between $15 to $40 per square foot for labor alone. For example, demolishing an existing deck can add another $600 to $1,000 to your budget.

Elevated concrete decks are even more costly, with labor charges ranging from $30 to $75 per square foot.

Staining your deck also involves additional labor expenses. Deck staining generally costs between $1.50 and $4.00 per square foot in extra fees. These figures highlight how labor influences the total cost when considering “how much does it cost to build a deck.

Building permit fees

Building permit fees can range from a couple of hundred to a few thousand dollars, depending on where you live. The typical cost for a new deck permit usually falls between $225 and $500.

These fees cover the inspection and approval process to ensure your deck meets local building codes.

Failing to obtain a building permit can lead to fines and may complicate future home sales. Check with your local municipality for specific costs in your area before starting construction.

This helps avoid surprises and ensures compliance with all regulations.

Ongoing Costs of Deck Ownership

Deck maintenance varies based on the material and climate. Regular upkeep ensures your deck stays safe and attractive for years.

Maintenance and repairs

Regular maintenance and timely repairs can save you money in the long run. Professional labor costs for maintaining a deck range from $15 to $35 per square foot, while deck replacement costs vary between $20 to $50 per square foot.

Routine tasks such as cleaning, sealing, and inspecting prevent bigger issues down the line.

Decks made of natural wood require more upkeep than composite materials. Natural wood decking needs sanding, staining, and resealing every few years. Regular inspections help identify problems like loose boards or damaged railings early on.

This proactive approach ensures your outdoor space remains safe and beautiful for years to come.

Insurance and taxes

Insurance for a new deck often increases your homeowner’s policy. Insurers consider decks an extension of your home, so adding one may raise premiums slightly. A typical increase might be around $50 to $100 annually, but rates vary by location and the deck’s value.

Taxes also affect the cost of owning a deck. Adding a deck can elevate your home’s assessed value, potentially raising property taxes. For example, if building a deck increases home value by 10%, expect an equivalent rise in tax bills.

Check local regulations to understand exactly how much you might pay.

More Financial Considerations When Building a Deck

Carefully plan your budget to account for any unexpected expenses. Use cost-effective materials to keep the overall expense manageable.

With an average return on investment of 89%, investing in quality work ensures that your deck adds significant value to your home. Our experts can navigate building permit fees and materials costs more effectively than most homeowners.

This not only reduces hassle but prevents budget overruns that often accompany amateur builds. Choosing skilled builders ultimately leads to durable, beautiful decks without hidden expenses or delays.

Choosing cost-effective materials

Pressure-treated wood is an excellent choice for budget-conscious homeowners. It costs between $15 to $25 per square foot, making it a cheaper option compared to other materials. This type of wood also stands up well against rot and insect damage, ensuring long-term durability with minimal costs.

Composite decking, while initially more expensive at $4 to $12 per square foot for materials only, offers lower maintenance expenses over time. Unlike wood, composite decks don’t require regular staining or sealing.

This option may save you money on upkeep in the long run. Using a deck cost calculator helps in comparing these options and finding what fits your budget best.

Deciding which features to include

Selecting the right features for your deck can significantly impact both its cost and functionality. Intricate designs may increase the overall costs, but they add unique character and appeal to the space.

Adding features like built-in seating, planters, or lighting enhances usability and comfort. For instance, composite decking materials typically range from $30 to $80 per square foot installed, which offers low maintenance but adds to upfront costs.

Considering your family’s needs helps in prioritizing essential features. Will you need more shade during summer? Consider installing a pergola or awning. If barbecues are frequent at your home, an outdoor kitchen could be worth considering.

Each feature incurs additional expenses but contributes to creating a versatile outdoor living area perfect for various activities.

Does Building a Deck Add Value to Your Home?

Building a deck can significantly boost your home’s market value. Prospective buyers often perceive it as an attractive feature, enhancing their interest in your property.

Increase in property value

A high-quality deck can boost property value significantly. Homeowners often see an increase in home value by 40% to 60% after adding a well-constructed deck. This addition not only beautifies the outdoor space but also provides functional entertainment areas, enhancing the overall appeal.

Moreover, the return on investment (ROI) for a deck is impressive. On average, homeowners can expect an ROI of about 72%. Choosing durable and appealing decking materials ensures long-term benefits in both functionality and home value enhancement.

Investing wisely in your deck project will pay off when assessing property worth or preparing for resale.

Potential resale value

Potential resale value increases significantly with a well-built deck. Experts estimate that decks boast an average return on investment (ROI) of 72%. Homeowners can recover up to 89% of the cost of a new wood deck through added home value.

Additionally, the potential resale value increase ranges between 40% and 60%, making it a smart financial decision for enhancing property appeal.

Decking material costs also play a crucial role in determining the final resale value. High-quality materials not only enhance aesthetics but also ensure longevity, enticing potential buyers.

This improved visual appeal helps homes sell faster and at better prices, justifying the initial investment in deck construction.


Building a deck is an investment that involves several factors influencing the cost. Deck size, materials, and labor rates play major roles in determining expenses. Considering ongoing maintenance and potentially adding insurance can also impact your budget planning.
