Gap Under Interior Door Threshold

I have searched quite a bit and can not find anything within the ada guidelines that specify the height of the door gap below the door gn said and sills are limited to 1 2 in height to comply with ada aka thresholds by the ibc.

Gap under interior door threshold.

Door draft stopper 2 pack under door seal for exterior interior doors door sweep strip under door draft blocker soundproof door bottom weather stripping 2 w x 39 l 4 1 out of 5 stars 354 9 99 15 99. I ve just paid a series of professionals to measure order install and paint a pre hung exterior door. There is a 1 5 inch gap between the threshold and the bottom of the wooden door. My contractor just hung our fancy dancy un painted solid wood door slabs in my 100 year old house with solid hardwood floors throughout.

But a gap of 1 5 inches seems excessive. The installer told me the shoe would cover the gap. Mike gn builders please cite the location of this ada requirement.
