Zoning certificate (CDU)

In short

The CDU (certificato di destinazione urbanistica, zoning certificate) is the certificate in which the municipality states the planning designation of a piece of land: what the local plan says about it. It is compulsory for selling agricultural or building land, it is issued by the municipality and it carries stamp duty.

The document at a glance

What it contains
The plan zone, the building indices, the constraints on the land and the reference to the planning instruments in force.
What it is for
Attaching it to the deed of sale of a piece of land, knowing whether you can build, understanding an auction lot before bidding.
Who can request it
Anyone, with a request filed at the municipality's registry (protocollo).
Where to request it
At the municipality where the land is. Or we request it for you.
What it costs
The municipality's administrative fees (diritti di segreteria), plus the revenue stamp (marca da bollo).
How long it takes
The municipality normally issues it within 30 days (art. 30 DPR 380/2001).
Legal value
Yes: it is the only document that is authoritative on the planning designation.
What it does not say It states today's designation. A new plan changes it, and the certificate is valid for the period stated in it. The designation we show on the map has no legal value: it helps you find your bearings, not sign a deed.

We request it from the municipality

The certificate is issued by the municipality: we open the application and deliver it to you. Where we have no zoning data, which is most of Italy, the CDU is the only way to know what can be done on that land.
