VINCOLI - Building restrictions -

VINCOLI - Building restrictions - PUGLIA, I recently requested a CDU from a commune to see if the property I consider getting has building/restoration restrictions - as many plots in Puglia have.What I got back was a generic document saying that in principle one can build but making reference to a number of plans, laws other regulations. As you can imagine that is not very helpful and still does not answer the question what you can and cannot do with the land...How do you figure out what vincoli apply to your property?Can a geometra make a comprehensive assessment and what is it worth?Any advice, please?Anyone with vincoli experience who would be willing to share a tip or two;) please pm me?
