What is the minimum required height of guardrails for decks or porches?

30 inches
36 inches
42 inches
48 inches

The correct answer is: 42 inches

The minimum required height of guardrails for decks or porches is 42 inches. This height is established to provide sufficient protection against falls, particularly on elevated surfaces. Guardrails are essential safety features for any elevated structure, ensuring that individuals are adequately protected from the risk of falling off the edge. The 42-inch height is recognized as a standard that balances safety with practicality, making it difficult for most people to accidentally fall over while still allowing the guardrail to be effectively installed and maintained. In this context, a height of 42 inches is mandated in many building codes and regulations to ensure compliance with safety standards, providing a robust barrier without obstructing views significantly or overwhelming the aesthetic of the deck or porch.
