Check property risks

Check the risks of a property before you buy it

To check a property's risks you need to cross-reference its location with official hazard mapping: river and coastal flooding, the 2024 DANA flood footprint and the revised flood zones, radon, seismic hazard, wildfires (forest mass, recent and active fire), power lines, industrial land and more. Hogarfax does it instantly from the address or the cadastral reference, using data from MITECO, CSN, IGN and others, and shows the distance and level of each risk. Start free; the full report costs €24.90 (VAT included).

Frequently asked questions

How can I check whether a property has risks?

Enter the address or the cadastral reference in Hogarfax. We locate the plot and cross-reference it with official risk mapping: flooding (MITECO), radon (CSN), seismic hazard (IGN/NCSE-02), wildfires (MFE, EFFIS and NASA FIRMS), power lines, industrial land, dams and more. The report shows the level of each risk, the distance and the source.

Which property risks matter most before buying?

It depends on location, but the ones that most affect value and use are usually: flood-prone areas (they limit renovations and raise insurance costs), radon exposure (health), seismic hazard (a criterion for inspecting the building), wildfire risk in the wildland-urban interface, and surrounding nuisances such as high-voltage lines, industrial land or noise from roads, trains and airports.

Can I check the risks for free?

The initial exploration is free and needs no account: you see the cadastral record, the facade photo and the market price. To unlock the full detail of all physical risks, land and surroundings, with the plot viewer and the PDF, the full report costs €24.90 (VAT included) as a one-time payment.

Does it work to check the risks of a plot or land?

Yes. It works the same for homes and for rural or urban plots anywhere in Spain. For land, besides natural risks, it is key to check the land classification, the easements (livestock trails, hydraulic and coastal public domain) and power lines, because they determine what can be built.
