A cadastral floor plan is a fundamental property document: a scaled technical drawing showing the internal arrangement of an apartment or other unit, including rooms, doors, windows and the precise distribution of space. Held by the Cadastre and now managed by the Italian Revenue Agency, it is essential in many situations, especially when selling or buying a home.
Before negotiations, it is prudent to check that the filed plan accurately matches the property. Removing partitions, rearranging rooms or creating a new space without updating the records results in a cadastral discrepancy.
Unlike an ordinary cadastral extract, which includes identifying and valuation data and is freely accessible, floor plans contain sensitive information about a property’s configuration. For security and privacy reasons, access is restricted to holders of property rights, such as owners, usufruct holders and bare owners. An owner’s heirs, with proof of their entitlement, and legal representatives of companies owning the property may also request it.
Owners frequently authorise another person to obtain the document on their behalf. Surveyors, architects, engineers, notaries and estate agents handling a sale or renovation often use this route. Written authorisation must be accompanied by a copy of the owner’s identity document so the Revenue Agency can verify the request.
The quickest method is online: an owner can enter the Revenue Agency’s secure area using SPID, an electronic identity card (CIE) or a National Services Card (CNS), view their property records and download the plan free of charge. Alternatively, they can visit a provincial land office with identification and any signed authorisation.
