In an existing strip shopping center which is owned by one landlord, they have two legal platted properties that share one raised patio sidewalk.
The question was, if each "property" has an accessible ramp adjacent each other, can they remove one and use the other to access the "property"?
The plan shows you the conditions...

In this scenario, there are two ramps located side by side, both landing at the raised patio. The patio is continuous across the two properties, so someone in a wheelchair wouldn't know that it was two different sites.
Since there is no physical architectural barrier to impede them from accessing either side, then only one ramp is required which will be the accessible route to both properties.
