Planning & EstimatingQuestion 487 of 700

During plan review of a two-story dwelling, you find the open side of an interior stair landing 40 inches above the floor below has no guard shown. What is the BEST action before construction proceeds?

a.Nothing, guards are only required on exterior decks
b.Ignore it because the framer will add one in the field
c.Flag it and require the plans be corrected to show a compliant guard, since the walking surface is more than 30 inches above the floor below
d.Wait until the final inspection to raise the issue

Explanation

The Residential Code requires guards where a walking surface is more than 30 inches above the floor or grade below; 40 inches exceeds that trigger, so a guard must be shown. The BEST practice is to correct the plans before building to avoid rework and a failed inspection. Options a and b are wrong because the guard is code-required regardless of location and should not be left to chance. Option d invites costly late-stage rework.
