I'm trying to figure out the minimum safe (and code compliant) height of an interior step between a kitchen and mudroom. I'm pretty sure 7 3/4" is roughly the max height but is there a minimum height specified? This is for a remodel. The height of the kitchen is fixed but I am replacing all floor framing in the mudroom so I can basically set it at whatever height I want. Headroom in the mudrooom requires a step of at least 2" but that is certainly a trip hazard.
I figure a step of 5" to 7" is OK but what about 3" or 4"? At what height does it go from step to trip hazard?
Thanks! I'd prefer to avoid asking the code official any unnecessary questions. He rarely gives me a helpful answer.
