What is the typical minimum height requirement for guardrails on decks?

The typical minimum height requirement for guardrails on decks is 36 inches from the walking surface. This standard is established to ensure safety, particularly in preventing falls from elevated surfaces. A guardrail that is at least 36 inches high is generally considered adequate to offer protection for occupants and to reduce the risk of accidental falls.

Building codes and regulations often cite this height as a baseline for residential and commercial decks, ensuring that they are functional yet compliant with safety standards. Ensuring that guardrails are at this height can help mitigate injuries and enhance safety for individuals using the deck.

Other heights provided in the choices either exceed or do not meet the standard practice for residential guardrails. It is important for building inspectors and designers to be aware of these dimensions to ensure safety regulations are met during construction and renovation projects.
