What does the code stipulate about deck construction?

The code requires that decks be designed for a live load of at least 40 pounds per square foot. This specification ensures that the structure is capable of safely supporting the weight of people, furniture, and any other items that may be placed on it. It is essential for maintaining safety standards in residential construction, as decks often serve as recreational spaces that experience varying loads. By adhering to this requirement, builders can help prevent structural failures that could potentially lead to injuries.

Other choices do not align with the code requirements. For instance, decks must be securely anchored to provide stability, not unanchored. Additionally, live load specifications are critical in deck design, which contradicts the idea that decks require no live load specification. The code does not stipulate that decks must be at least 5 feet off the ground; height restrictions generally depend on specific local regulations or safety requirements related to guardrails.
