Flood zone

Is that house in a flood zone? Check before you buy

To know whether a house is in a flood zone, you cross its location with MITECO's official flood hazard maps (river, from rain or rivers, and coastal). Hogarfax does it instantly from the address or the cadastral reference and shows whether the plot falls within a hazard zone (T100 return period), how far it is from the watercourse, and a map of the constraint. More than 2 million homes in Spain are at flood risk. Start free; the full report costs €24.90 (VAT included).

Frequently asked questions

How do I know if my house is in a flood zone?

Enter the address or the cadastral reference in Hogarfax. We cross the plot with MITECO's official flood hazard mapping (river and coastal) and show whether it falls within a hazard zone for the T100 return period, how far it is from the watercourse, and display it on a map. It is the same information the authorities use, made understandable.

What is the difference between river and coastal flooding?

River flooding is caused by rivers overflowing or by intense rainfall accumulating; coastal flooding is caused by storms, surges or sea-level rise in coastal areas. The report checks both separately, because a property may be exposed to one, the other or neither.

Does living in a flood zone affect insurance and the mortgage?

It can. Being in a hazard zone usually raises home insurance costs and, in some cases, affects the valuation or limits renovations and extensions due to watercourse easements. Knowing before you buy lets you negotiate the price or rule out the property with good reason.

Can I check the flood zone of a plot or land?

Yes. It works the same for homes and for rural or urban plots. For land it is especially important, because the hazard zone and watercourse easements may prevent building on part or all of the plot.
