What the AI looks for in Decking Railings

When a guard is required: US residential code (IRC) generally requires guards where the deck surface is more than 30 inches above grade This decides whether the railing is decorative or a structural safety element.
Height: At least 36 inches for residential guards under the IRC, 42 inches for commercial work and some local codes Rail kits come in fixed heights, so buy the one your jurisdiction requires.
Load rating: The top rail and posts must resist a 200-pound concentrated load, so use systems tested to code and posts attached with through-bolts or tested brackets and blocking Posts held only by lag screws into the rim joist are a common failure point.
Section length: Do not exceed the manufacturer's maximum span between posts, typically sold as 6-foot or 8-foot sections Longer spans sag and fail load requirements.
Stair handrail: Stairs need a graspable handrail, and a 2x6 top cap alone usually does not qualify Graspability is a separate code requirement from guard height.
Cable railing tension: Cable infill needs stiff end posts and regular re-tensioning so cables stay within the 4-inch opening rule Sagging cables can spread apart enough to fail inspection.

Under the IRC, guards are generally required only above 30 inches, but check local code, and stairs may still need a handrail.
