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.

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.
