Cost to build 12×20 deck

Building and installing a deck on your home can be a challenging project. The amount of work involved will vary depending on the size and style of the deck you want to build.

On average, you can expect to pay between $200 and $300 per square foot for a wood deck. A 12-by-20-foot deck would cost around $2,400 to $3,000.

The cost of building a small wooden deck is fairly straightforward: it’s just the price of materials plus labor. However, if you’re building a large or complex deck with multiple levels, steep grades or unusual shapes, you might need an architect to design it for you. If so, expect to spend another $1,000 to $2,000 for this service.

Costs for labor include carpenters’ wages and any permits that are required by your city or county government — usually about $100 per permit application but sometimes much more if there are many steps involved in getting approval from multiple agencies such as fire departments and health departments

Labor costs vary greatly depending on the time of year, experience of the contractor and what other materials are needed for your project. Labor costs also vary based on where you live and the type of deck you’re building.

For example: If you’re hiring a contractor to build a simple deck for $5,000, that may be all you pay. In another case, if you’re hiring a contractor to build a complex multi-level deck with stairs, it might cost $10,000 or more.

Here’s how much it could cost:

Labor for framing (the part where you raise the walls) is about $4 per square foot for an average sized deck. So if your deck is 100 square feet, it would cost about $400 in labor alone just to frame it.

Lumber (wooden planks) averages between $1 and $2 per linear foot so if your project is 100 linear feet long then expect to spend anywhere from $100 – $200 on lumber alone.

Materials like nails and screws add another $2 per linear foot so if your project is 100′ long then expect to spend anywhere from $200 – $400 just on materials such as nails or screws alone.
