Before we dive into the costs, it's essential to define what constitutes a "small deck." Generally, a small deck is around 100 to 200 square feet, typically no larger than 10 feet by 20 feet. This size is perfect for most residential properties, providing ample space without overwhelming your yard.

Pressure-treated lumber

Pressure-treated lumber is an affordable option that resists rot and insect damage. It's a popular choice for small decks due to its cost-effectiveness. However, it requires regular maintenance, such as staining or sealing, to maintain its appearance.

Example: A 12' x 16' (192 sq. ft.) deck using pressure-treated lumber would cost around $384 - $960 for materials alone.

Composite materials

Composite decking is made from a combination of recycled plastics and wood fibers, making it eco-friendly and low-maintenance. It's more expensive than wood but requires no painting, staining, or sealing. It also resists rot, mold, and mildew.

Example: The same 12' x 16' deck using composite materials would cost around $1,536 - $4,800 for materials.

DIY vs. Hiring a Professional

Building a small deck yourself can save you money on labor costs, but it's essential to consider your skill level and the time commitment involved. Complex designs or structures may require professional help to ensure safety and structural integrity.

Before you decide to DIY, research the project's complexity, and be honest about your skill level. It's better to hire a professional if you're unsure about any aspect of the build to ensure your deck is safe and long-lasting.

Additional Costs to Consider

In addition to materials and labor, there are other costs to consider when budgeting for your deck project:

  • Permits: Check with your local building department to determine if you need a permit for your deck. Permit fees can range from $50 to $500 or more, depending on your location and the size of your deck.
  • Footings and foundation: The cost of footings and foundation materials can vary but typically ranges from $2 to $5 per square foot. These costs are often included in the labor estimate if you're hiring a professional.
  • Railings and balusters: Railings and balusters add safety and visual appeal to your deck. The cost can vary depending on the material and design, typically ranging from $2 to $10 per linear foot.
  • Stairs and landings: If your deck requires stairs or landings, these features can add to the overall cost. The price can vary depending on the size and complexity of the structure.

Now that you have a better understanding of the costs involved in building a small deck, you can create a more accurate budget for your project. Keep in mind that prices can vary depending on your location, the time of year, and the current market conditions. Always obtain multiple quotes from reputable contractors to ensure you're getting the best value for your money.

As you embark on your deck-building journey, remember that a well-designed and constructed small deck can significantly enhance your outdoor living space and add value to your home. So, start planning, and enjoy the process of creating the perfect outdoor retreat for you and your loved ones.
