In ArcGIS, If you create a field within the polygon layer containing the radius (400 feet), you can use the centroid to calculate a buffer of the point.  You could also buffer the outside of the parcel using the same method which may be more in keeping with your desired results?

Is there a way to automate creating a single maximum-sized circle within each polygon of a parcel layer?  The polygons could be any shape.

 

This would be useful for identifying potential parcels that could contain a Massachusetts Zone I (400’ radius) of a proposed water supply well.
