From address to parcel: what is the relationship?
Addresses, buildings and cadastral parcels describe different objects. How to read them together without assuming ownership or surveyed boundaries.
Start with the address
Search by street, number and municipality, or by the 14-character cadastral reference that identifies the parcel. The address and the building are different objects from the parcel: one building can have several addresses and one parcel several buildings.
Read the card with care
The cadastral area and the area calculated from the boundary may differ. The construction year, floor area or number of homes are what the cadastre records, not the result of an inspection.
A cadastral parcel is a fiscal unit: it does not say who owns it. Ownership is recorded in the Land Registry (Registro de la Propiedad).
Check it at the official source
For any formal step, obtain the descriptive and graphic record or a certificate from the cadastre's online office (Sede Electrónica del Catastro).
