What is the minimum guardrail height required on a residential deck?

Explanation:
Guardrails on dwelling units have a code-minimum height to provide effective fall protection. The required height is at least 36 inches, with many codes also allowing up to 42 inches depending on the jurisdiction. So the smallest height that still meets the code is 36 inches. Heights like 40 or 42 inches can be acceptable if they’re within the local code’s maximum, but the minimum you must meet is 36 inches. A guard height of 32 inches would not meet the minimum and would be non-compliant.
