All decks and porches located more than how many inches above the floor or ground should have guards?

The correct threshold for requiring guards on decks and porches is established by building codes to ensure safety and prevent falls from elevated surfaces. When a deck or porch is more than 30 inches above the floor or ground level, it poses a significant risk, making it essential to have protective barriers or guardrails in place.

In residential construction, this height is widely recognized as a standard that balances safety needs with practical design. Guardrails provide critical protection for individuals using elevated structures, particularly in environments where children or pets may be present.

While some jurisdictions may adopt different codes or guidelines, the requirement for guard protection above 30 inches is commonly referenced in building standards to help inspectors assess safety compliance effectively. Thus, knowing this standard is crucial for home inspectors when evaluating properties.
