Q1.) When a ramp has a maximum slope of 1:12 or 8.33%, is that considered a range of from 0% to 8.33% which would allow no slope greater than 8.33% or is that a simple maximum which would allow a tolerance above 8.33%? Similarly, is a cabinet countertop that can be no higher than 34” AFF a range of from 0” to 34” AFF with no additional height allowed, or is a tolerance allowed for variations in the floor surface or cabinet construction?
A1.) The consistent technical assistance on this question has been that both are subject to tolerances.
