Some elevated decks require stairs that lead to the ground level per the local fire codes in some municipalities. In other regions, a staircase is an optional feature that can increase accessibility and convenience for homeowners who want ground-level access to their deck. Additionally, a staircase is necessary if your home doesn't have an existing door leading to the deck.

Most building codes require that spindles or balusters on deck and stair railings be spaced no more than four inches apart. This safety standard, often called the '4-inch sphere rule,' is designed to prevent small children or pets from slipping through the railing. A good way to visualize this is that a 4-inch sphere should not be able to pass between two spindles. For the same safety reason, the space between the bottom rail and the deck floor should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is crucial to check your local building codes to ensure compliance before starting your project.

Composite decking boards aren't your only options for building a deck. There are several other types of materials for decks, including wood and aluminum decking. Wood decking comes in many different wood species, offering natural beauty and classy timelessness to your yard. Aluminum is a lightweight, water-resistant, and low-maintenance material that is also non-slip.

When deciding if you should use 2x6 or 2x8 deck joists, consider the size of the deck, joist spacing, and materials. Larger decks, larger-spaced joists, and weaker wood all require more support, meaning they need larger joists. For example, 2x8 redwood joists spaced 16 inches apart can only safely span up to 10 feet and 7 inches. On the other hand, 2x10 southern pine joists spaced 12 inches apart can be as big as 16 feet and 2 inches. If you aren’t sure what size joist is best for your project, speak with your deck builder.
