You receive the cadastral record for a property you need to evaluate. You open it and find a sequence of codes, abbreviations, and numbers: sheet, parcel, subaltern, a category made up of letters and numbers, and a cadastral income. Knowing how to read them accurately is an everyday skill for a real estate agent. It allows you to correctly interpret a property, identify anomalies before they become problems at the closing, and confidently explain every detail to the client.

Why an E&V agent reads the cadastral record before anyone else
A cadastral record is an official document issued by the Italian Revenue Agency. It provides a snapshot of a property's cadastral status at a given point in time: its identification details, characteristics, cadastral income, and registered owners.
Here, it is important to make a distinction that is fundamental to the entire due diligence process. The cadastre is primarily a fiscal tool: it is used to record properties and determine their cadastral income, which is used to calculate taxes. The land registers (the Conservatoria) are instead the tool that protects real property rights: this is where ownership, mortgages, foreclosures, and easements are registered.
The consequence is important. The cadastre is not a legally probative authority: its data do not constitute legal proof of ownership. The cadastral owner is not necessarily the actual legal owner. For this reason, the cadastral record does not replace the property title search. The former shows what the property consists of and its cadastral income; the latter shows who actually holds title to it and whether it is subject to any encumbrances. Both are needed in a property transaction.

The first part of the cadastral record uniquely identifies the property. These are the details that locate it precisely within the cadastral records.
The municipality indicates where the property is located, along with its cadastral code. The urban section is not always present: where this subdivision exists, it identifies a specific area within the municipality.
The sheet is a portion of the municipal territory, as represented by the cadastre on its maps. The parcel, also known as the map reference, identifies the individual building or plot of land within the sheet. The subaltern identifies the individual property unit within a parcel: in a condominium, each apartment has its own subaltern. When a building consists of a single unit, the subaltern may be absent.
The practical check to carry out is simple but essential: these details must exactly match those indicated in the title deed. This is how you confirm that the property shown on the cadastral record is actually the one being evaluated. Even a minor discrepancy should be clarified before proceeding.
These three details describe the nature and cadastral size of the property.
The category indicates the property's intended use. Residential properties fall under group A (for example, A/2 for standard residential properties, A/3 for economy-class properties, up to A/1, A/8 and A/9 for luxury homes, villas, castles and buildings of outstanding artistic or historical value); garages and storage units fall under group C.
The class is a quality parameter within the category: for the same category, it distinguishes properties with different levels of quality and profitability.
The cadastral size is the cadastral measurement of the unit. It is expressed in rooms, square metres or cubic metres depending on the category. It is a figure that should not be confused with the commercial floor area, which is calculated using different criteria: the two values do not coincide, and this is an area where it is easy to create misunderstandings with the client.
The cadastral income is a tax value assigned to the property. For properties in groups A, B and C, it is calculated by multiplying the cadastral size by a unit rate specific to the municipality, cadastral zone, category and class. For groups D and E, it is determined through a direct assessment.
The cadastral income is almost always out of line with the market value, and that is normal: it does not measure how much the property is worth, but serves as the basis for calculating taxes. IMU, registration tax and other taxes are calculated based on it. Knowing the cadastral income therefore makes it possible to estimate the property's tax burden in advance.
There is also a more nuanced use, typical of an experienced agent. A cadastral income that is significantly lower or higher than that of similar properties in the same area may signal something that needs further investigation: an outdated classification, or a category that no longer reflects the property's actual condition following building works.
The cadastral record lists the registered owners, along with their personal details, tax code, type of right, and ownership share.
The first check is one of consistency: the registered ownership should match the person presenting themselves as the owner. When it does not, you need to stop and understand why. As mentioned above, cadastral ownership has no probative value: actual ownership must be verified in the land registers. However, any discrepancy should always be clarified.
Some situations are common and require particular attention. Bare ownership and usufruct separate ownership of the property from the right to use and enjoy it: the person selling must have the right they claim to be transferring. Undivided ownership between multiple parties means that the property belongs to several people in different shares: in this case, to sell the entire property, the consent of all co-owners is required. Recognizing these arrangements from the cadastral record allows you to structure the transaction correctly from the outset.
Some situations, when reviewing a cadastral record, should raise a red flag.
The first is a discrepancy between the cadastral floor plan and the property's actual condition. If the layout of the spaces shown on the floor plan does not match the property as it actually is, there is a discrepancy that needs to be remedied: this is one of the problems that most often emerges during the closing process.
The second is an outdated property category following a renovation. A property that has been significantly modified but is still classified according to its previous condition has a discrepancy that needs to be corrected.
The third is a cadastral income that is inconsistent with the property's actual characteristics, which is often a sign of one of the two situations described above.
The fourth is ownership details that have not been updated following an inheritance: sometimes a property is still registered in the name of a deceased person because the change of ownership has not been recorded. Before proceeding, the inheritance situation must be reconstructed.
In all these cases, the agent's role is not to solve the technical issue, but to identify it, clearly flag it to the client, and direct them to the right professional.
Knowing how to read a cadastral record at this level of detail is a way of protecting the client.
Engel & Völkers agents receive in-depth technical training precisely because identifying a cadastral anomaly early means protecting both the client and the transaction. A problem identified during the preliminary assessment is a problem that will not emerge unexpectedly at the closing, when it would be much more costly and difficult to manage.
This is what distinguishes someone who simply reads the data from someone who knows how to interpret it. For the agent, it is also the most solid way to build a professional reputation: technical expertise, in the luxury segment, is an integral part of the service.

FAQ on how to read a cadastral record
No. The cadastre is not a legally probative authority: the cadastral owner is not necessarily the legal owner. Ownership is verified in the land registers through a property title search.
A property search provides the details of a single property. A person search lists all the properties registered to an individual or legal entity.
The parcel, or map reference, identifies a portion of the municipal territory represented on the cadastral sheet. The subaltern, on the other hand, identifies the individual property unit within the parcel, such as an apartment, garage, cellar or commercial unit.
Because it is a tax value used to calculate taxes, not a market valuation. It serves as the basis for IMU, registration tax, and other taxes.
Discrepancies between the floor plan and the property's actual condition, an outdated property category following a renovation, an inconsistent cadastral income, or ownership details that have not been updated following an inheritance. In these cases, it is advisable to involve a qualified professional.
