What is the minimum height requirement for guardrails on a residential deck?

The minimum height requirement for guardrails on a residential deck is typically set at 36 inches. This height is designed to provide adequate protection against falls, particularly in residential settings where the risk of injury can be significant. The requirement ensures that guardrails are tall enough to prevent individuals, including children and pets, from easily climbing over them or falling off the edge of the deck. It also balances safety with practicality, as a height that is too low may offer insufficient protection, while a height that is excessively high may be cumbersome for users.

Local building codes may vary, but 36 inches has been widely adopted as a standard for residential guardrails to help ensure safety without being overly restrictive.
