Intent
Intent 1: 
To limit the probability of an inappropriate grade or thickness of subflooring relative to joist spacing, which could lead to inadequate stiffness or strength, which could lead to an inability to resist expected gravity loads, which could lead to the failure of subfloors between floor joists, which could lead to persons breaking through flooring, which could lead to harm to persons.
