SCHRAIBMAN'S COMMENT: The way I see it the almost immediate implications are as follows:
1) All commercial lease are about to undergo a change in that this aspect needs to be reflected at 7/1/13
2) The inspection has to be carried out by a CASp- not just any other party
3) And if inspected by a CASp, the property has to be brought up to compliance with all applicable accessibility standards, which means costs.
One could also read all sorts of other potential issues, such as responsibility falling back to the owner for non-compliance issues and the cost of defending against litigation. In addition to this, if two properties are the same a prospective tenant who is savvy would likely go with the property that affords them the least exposure. The long term implications seem to be leaning to everything being CASp certified eventually and hence everything being compliant with all applicable accessibility standards.
