What does the ZÜRS flood zone mean for my insurance in Germany?

In short

The ZÜRS zone shows how often flooding is expected at your address in Germany, from class 1 (no known risk) to class 4 (at least once in ten years). Over 90 percent of all addresses are in class 1 and pay little. In classes 3 and 4 premium and deductible rise sharply, and some insurers decline.

What it costs

Guide values for the natural hazard add-on of a detached house, by ZÜRS class.

ExampleTypical range
Detached house, class 1about EUR 50 to 200 a year extra
Detached house, class 3about EUR 400 to 600 a year, more in individual cases
Apartment building, per unitabout EUR 30 a year
Usual deductible10 percent of the loss, at least EUR 500, at most EUR 5,000

Guide values as of September 2026 from published examples.

That the class 2 surcharge is usually only a few euros a month and that class 4 often costs over

EUR 1,000 a year are guide values from our quoting practice.

Worked example

Two identical houses, two zones

Two identical detached houses in the same town: one up on the slope, one 200 metres from the river.

House on the slope, class 1about EUR 100 natural hazard add-on a year
House by the river, class 3about EUR 500 a year
Deductible by the river10 percent, at least EUR 500
Flood damage by the riverEUR 40,000

By the river you pay EUR 4,000 yourself and the insurer pays EUR 36,000. Without cover, all EUR 40,000 would stay with you.

What the abbreviation stands for

ZÜRS stands for Zonierungssystem für Überschwemmung, Rückstau und Starkregen, a zoning system for flooding, sewer backflow and heavy rain. German insurers use it to put every address in the country into a hazard class; over 22 million addresses are covered.

The flood class only describes the risk from rivers and streams. Heavy rain has a second rating in three classes, based on whether the house stands on a hilltop, on flat ground or in a valley. Just under 12 percent of addresses are in the highest heavy rain class.

ZÜRS classStatistical floodingWhat it means for you
Class 1none as far as knowncover almost everywhere at a low price
Class 2less than every 100 yearsusually no problem, small surcharge
Class 3every 10 to 100 yearsmuch more expensive, higher deductible, some decline
Class 4at least every 10 yearsonly after individual review, often with conditions

How the zone sets premium and acceptance

The insurer looks up your address and gets the class back. That determines the surcharge and the deductible (Selbstbeteiligung), and often whether the insurer accepts the policy at all.

The class is not everything: previous claims, a basement on a slope or an old backflow valve also count. In the other direction, flood-resistant construction in class 3 can lower the price.

What is different if you come from abroad

In Germany flood cover is not included by default. You add it to buildings or contents insurance as natural hazard cover (Elementarschadenversicherung), and it is optional. The state does not guarantee compensation after a flood.

If you are buying a house, check the ZÜRS class and get a quote before you sign. A class 4 address can make cover expensive or hard to get, and banks may ask about it.

When the zone may be wrong

The rating works with addresses and maps. If your house stands clearly higher than the street or behind a new dyke, the class may be too high.

Then it pays to collect evidence: elevation data, flood maps from the federal state, proof of protective works. Some insurers review this individually on request. There is no right to a lower class, though.

When you do not need to worry about the zone

If your address is in class 1, the zone hardly affects price or acceptance. The heavy rain class matters more then, because heavy rain also hits houses far from any river.

You can check your address free of charge in the flood check of the German insurance industry (Hochwasser-Check).

Step by step

  1. Look up the class of your address in the flood check of the German insurance industry.
  2. Note the heavy rain class too, it counts separately.
  3. Check whether the local situation matches the rating and collect evidence if not.
  4. Compare quotes with the same deductible, otherwise prices are not comparable.
  5. In class 3 or 4, ask early and send details of protective measures.

Checklist

  • Flood class of the address known
  • Heavy rain class of the address known
  • Deductible worked out in euros
  • Policy conditions read, for example on backflow valves
  • Evidence of protective measures collected

Common mistakes

  • Skipping natural hazard cover in class 1 although heavy rain can hit anywhere
  • Comparing only premiums and overlooking the higher deductible
  • Giving up after one refusal instead of asking other insurers
  • Not mentioning new dykes or protective works

Questions and answers

Frequently asked

How do I find out my ZÜRS zone?

Through the free flood check of the German insurance industry, where you enter your address.

Your insurer or we can also look it up.

Can my zone change?

Yes.

The data is revised regularly, for example after new dykes or new flood maps.

That can lower or raise your class.

Can class 4 be insured at all?

Often yes, but only after individual review, with a high deductible or conditions.

Not every insurer offers it.

Does the zone affect normal buildings insurance?

Fire, storm and burst pipe cover hardly change.

It mainly affects the natural hazard add-on.

Does the zone apply to contents insurance too?

Yes, the natural hazard add-on for contents is also rated by address.

The surcharge there is usually smaller.
