Cadastral data for agents: using parcel records to prospect smarter

What the cadastral reference is, and why you need it

Spain’s Real Estate Cadastre Act gives every property a cadastral reference: an alphanumeric code that places it unambiguously on the official map. The same law requires that reference to appear in documents with economic or tax relevance linked to the property. For an agent that has a practical consequence: the cadastral reference is the key that ties together the plot on the map, the owner’s record and the contract they will eventually sign.

The law classifies properties as urban, rural or special. Knowing which one you are dealing with before the first call stops you offering a home buyer a rural plot they cannot use the way they imagine.

What the Spanish cadastre tells you, for free

The Cadastre’s online office lets anyone check the non-protected data of any property for free, from its cadastral reference or its address: location, built and plot area, use, year of construction and the map with its boundaries. It is the first filter for knowing whether a property fits what your buyer wants before you lift a finger.

What it does not tell you: protected data

This is where many people get it wrong. Article 51 of the law treats as protected data the name, surname, company name, identification number and address of whoever is registered as cadastral holder, as well as the cadastral value of the land and the building. None of it appears in the open search: only the holder, and those covered by the cases the law itself provides for, can access it.

Two conclusions. First: the cadastre does not give you the owner’s name to call them. Second: even if you had it, the cadastre does not prove ownership. Ownership and encumbrances — mortgages, seizures, easements — are confirmed at the Land Registry, by requesting a “nota simple” through the Spanish Association of Registrars. To prospect, the cadastre is enough; to close, cross-check both.

If you work in Spain, add the difference between cadastral use and planning classification: a “residential” entry in the cadastre does not mean planning allows what the buyer wants to do.

What the cadastre tells you in Estonia

In Estonia the cadastre is published by the Land and Spatial Development Board (Maa- ja Ruumiamet), formerly the Land Board. Every cadastral unit has its reference (katastritunnus, formatted 12345:678:9012), its geometry, its area and its designated use (sihtotstarve). All of it can be checked on a map in the geoportal.

The division of roles is similar to Spain’s, but across four separate registers:

• The cadastre says what the plot is: boundaries, area and use.
• The land register (kinnistusraamat) says who owns it and what encumbrances it carries.
• The building register (EHR) says what is built and registered on it.
• Planning says what may be built. We explain it in what sihtotstarve means: the cadastral use is not a building right.

From one-off lookups to a working map

Looking up one plot is fine. Having your whole area on one map, with every plot coloured by what has happened there, is a different level: you stop working from memory and start working from a record the whole team shares.

• You spot gaps: streets where you have not spoken to anyone.
• You prioritise: the plots most likely to sell come first.
• You do not tread on a colleague: what has already been worked is visible.
• You prepare every visit with the data in front of you, not from memory.

Cadastre plus fieldwork

Data comes alive in the street. If you plan door-to-door prospecting routes on the cadastral map, every agent leaves with a list of plots and notes down what they see. The public data — area, use, year — is completed with what you only learn on foot: the real condition, another agency’s sign, building work under way, whether the owner lives there or rents it out.

The cadastre tells you what is there; the street tells you what is going on. Put them on one map and you stop improvising.

Watch the personal data you add yourself

The cadastre does not give you the owner’s name, but the street does: they tell you at the door. The moment you write it down next to their phone number you are processing personal data, and the General Data Protection Regulation applies: you need a legal basis to keep it and you must tell the person what you will do with it. It is not an obstacle — it is one more reason for that data to live in a system with permissions rather than in a notebook.

How Domuspace handles it

The cadastral map brings all of the above into one screen:

• You work on the real plots of your area, with the official cadastral geometry. Tap a plot and its record opens.
• Every plot is coloured with one of six fixed statuses: wants to sell, considering it, future sale, does not want to sell, not at home, and exclusive. The whole team works on the same map, and colleagues see your colours when they reload or, within a few minutes, as they move around the map.
• On the plot itself you store the owner’s contact and whatever property details you have found out, tied to its cadastral reference.
• You are not limited to the town centre: you also work rural land, in Spain and in Estonia.
• There is a separate mode for leaflet drops, with age colours that show which street is due again.

On coverage, plainly: today it covers all of Estonia and the whole province of Málaga, Costa del Sol included, and each company works the plots of its own country. The next area planned is Cádiz, with no date yet. The map is available from the Basic plan. If you work somewhere else, write to us.

From the map to the listing pitch

When you knock on a door knowing the area, the year and the surroundings, you speak with authority. Add a valuation based on real comparables and you are no longer “just another salesperson”: you are the person who knows their home best. That is the shortest road to the exclusive.
