A second-story deck is one that attaches to an upper level of a house and may require stairs to move from an upper level to a lower level or the ground. For example, let's say you have a living room or kitchen with a great view of the backyard. The room is above your finished basement that opens directly to your backyard. You decide to install a second-story deck to enjoy the beautiful outdoors right outside the heart of your home. Take a look at some second-story deck ideas for inspiration as you consider second-story deck costs.
How Much Does It Cost to Build a Second-Story Deck?
In general, the cost to build a second-story deck can be anywhere from $30 to $60 per square foot as a national average. DIYers can install their own elevated deck, but they must follow IRC building codes just like a contractor does. You may need to get permits from your local housing authority, as well. Permitting will increase the costs. Typically, a deck that's 10 feet by 12 feet will cost $3,600 to $7,200 for materials only.
Labor costs increase with a second-story deck because it requires more materials to install than a ground-level deck. Pressure-treated wood comes with the lowest price, while composite decking costs more but needs less maintenance as it resists rot and weather better than wood. A second-story deck also needs more bracing to stiffen and support the structure above it. If you want an estimate on your project, take a look at how to calculate the costs of building a deck while trying to determine your second-story deck costs.
