The building permit determines the structure of the building you can build. It does not determine its use. The lands zoning is what determines its use. In this case they were permitted to build a structure categorized as "Agriculural Storage Building". That is the style of building they were permitted to build on that site. The zoning however, is what determines the activities that can be performed on the site. So all in all the building permit allowed them to build an "agricultural storage building" and the zoning allowed them to perform the activities of "agricultural use: value added" as defined in the by-laws. That is until tonight, which I'm far from certain will apply to Cen.
