I am managing replacement of a bathtub with a walk in shower for my mother in her condo. The HOA is demanding a shower grade of 1 inch per foot which seems far to steep for a person with disabilities. What is the standard grade and curb height for an ADA compliant shower?

Ramps(in general) are permitted to be 1:12 (though it is recommended that they be less steep), but areas that are considered wheelchair turning, transfer, parking etc. are limited to 1:48. Nothing specific to "shower floor grade" is in there, but depending on how it's intended to be used (or intended to be ABLE to be used) you could get the 1:48 limitation applied - it's still perfectly good for drainage (1/4" per foot.) 1:12 is not particularly comfortable for normal folks, and is far more than is required for plumbing drainage.
