Property Cadastral survey: what’s the use

The cadastral survey of Buildings is the "identity card" of a property.

This document is issued by the Revenue Agency of the Italian Republic and contains all the information registered at the land register concerning the properties (building register) and the land (land register) located in the national territory.

The data contained in the cadastral survey

First of all, the municipality, the address and the floor of the apartment are indicated.


It is a numerical data that refers to a given territorial unit of the Municipality.

Each municipality, in fact, is divided into different sheets on which the various properties are represented.

Simply put, using the sheet you can locate the area in which the real estate unit is located.


Map number: it is a numerical data that identifies the building located in the territory of the Municipality and its possible area of ​​relevance.


It is a numerical data that identifies the apartment located inside the building which, in most cases, is made up of multiple real estate units.

In the event that a building consists of a single real estate unit, the subordinate could be missing and therefore, in these cases, in the cadastral survey the last data reported is the parcel.

Census area

Indicates a portion of the municipal territory with certain similar environmental and socioeconomic characteristics and in which the profitability of the buildings is uniform.

Cadastral category

It represents the type of a property and the intended use (residential home, office, shop, warehouse, laboratory, etc.)


It is a parameter that identifies the level of productivity of real estate units belonging to cadastral categories A, B and C.


Indicates the number of cadastral rooms of which the real estate unit is composed.

Cadastral surface area

This refers to the gross surface area in square metres, i.e. the walkable surface area with the addition of the thickness of the internal walls.

It is suitable for shops, warehouses and garages (land registry category C).

Only recently has it also been reported for real estate units intended for residential use (land registry category A).

Cadastral income

Indicates the income that the Revenue Agency attributes to each property.

This data is very useful because it allows you to calculate the registration tax in the case of purchasing the property, the IMU, and income taxes.

Personal data

Of the owner or owners: place, date of birth, tax code.

Ownership share

Of each owner in the case of a property with multiple owners

Historical cadastral survey

The historical cadastral survey lists in chronological order all the events that affected the property (previous owners, splits, mergers between multiple properties, changes in destination, updates to the cadastral income, etc.)

The cadastral survey is therefore of great importance and is one of the indispensable documents in real estate sales because it precisely identifies the property that is the subject of the transaction.

It has no legal or even probative value: it has a simply informative and fiscal function.

The cadastral survey may not show the name of the current owner because the cadastre is not always updated.

To determine with certainty who is the current owner of a property it is necessary to find the notarial deed of origin (deed of sale, inheritance, donation).
