What is the minimum height allowed for railing on a residential deck?

The correct minimum height for railings on a residential deck is typically set at 42 inches. This height is established to provide adequate safety and protection for occupants against falls, especially for elevated decks. The rationale behind this regulation is that a higher railing significantly reduces the risk of accidents, particularly for children or individuals who may unintentionally lean over the edge.

This standard is reflected in various building codes and guidelines to promote safety in residential construction. A railing height of 42 inches strikes a balance between being high enough to prevent falls while still being manageable for maintenance and usability. Therefore, adhering to this height requirement is critical for ensuring that residential decks meet safety regulations and provide a secure environment for all users.
