Use the code to find the specific home
A property's cadastral reference contains twenty letters and numbers. Use it to search for its information. Locating a building's plot may produce a list of flats, premises and other properties; choose the relevant one.
Check the address and, where shown, staircase, floor and door. Check whether the result describes a home or commercial premises. Finding the correct building on a map is a start, but you still need to confirm the space being purchased.
- Review municipality, street and number.
- Confirm floor and door with the agent or seller.
- Clarify whether garage and storage room have separate details.
Request it if the listing omits it
Ask the seller or agent for the property's reference. Explain that you want to check its details before visiting or comparing homes. Save the code alongside the listing.
If the door, street name or description differs, ask why. There may be a straightforward reason, but clarify it before treating the result as the home you visited.
- Request the reference of the home being sold.
- Save the listing and supplied address.
- Ask about any floor or door discrepancy.
Read carefully which areas you are comparing
Land, built area and usable area describe different things. Usable area concerns the space you can use; built area includes walls and, depending on the figure, may include a share of common spaces.
A difference from the listing therefore does not automatically mean someone made a mistake. First ask which area measure each document uses. Keep terraces, garages and storage rooms separate to understand the actual offer.
- Ask whether the areas are usable or built.
- Check whether shared spaces are included.
- Review terrace, garage and storage room separately.
Use it for identification and request documents for other questions
The reference helps locate and distinguish a property. To check who is selling or whether debts and other obligations exist, you need the appropriate documentation. Finding the home in Catastro does not resolve every purchase question.
The same applies to an extension in the data or a photograph: its appearance does not demonstrate permission. Record what you want clarified and request documents, with your adviser's help when needed.
- Separate identification from sale documentation.
- Request explanations and papers for questionable work.
- Clarify important differences before proceeding.
Frequently asked questions
Is the building's reference enough to buy a flat?
It can help find it, but check which flat the result describes. If several properties appear, review floor and door. If they are not distinguished, ask the seller or agent how your purchase is identified.
Does a floor-area mismatch mean a problem?
Not necessarily. The listing and Catastro may use different area types or include different spaces. Ask what each figure counts and request documents to clarify it.
