Mandatory natural hazard insurance: what does it mean for homeowners?

Ever since the Ahr valley flood disaster, German politics has debated whether natural hazard insurance (Elementarversicherung) for residential buildings should become mandatory. Friedrich Merz and his party have repeatedly argued that the community of policyholders – not the taxpayer – should carry the cost of natural catastrophes; in the 2025 coalition agreement, the federal government committed to introducing nationwide mandatory natural hazard cover, with the exact design still being negotiated. What does that mean for property owners?

What natural hazard insurance actually covers

A standard German buildings insurance policy pays for fire, tap water damage, storm and hail. Natural hazard cover is the rider on top:

• Flooding and heavy rain (by far the most frequent cases)
• Sewage backup from the drainage system
• Landslide, subsidence and earthquake
• Snow pressure and avalanches

Exactly this rider is missing from many policies: according to industry figures, only about half of Germany's residential buildings are insured against natural hazards – with large regional differences.

Why a mandatory scheme is on the table

After every major flood, the state has so far paid billions in aid to uninsured owners. The proponents' arguments:

1. Universal protection: no owner faces existential ruin after a catastrophe.
2. Fair distribution: the risk is carried by the community of policyholders – not by taxpayers via ad-hoc relief packages.
3. Predictability for the state: disaster aid becomes calculable instead of budget-breaking.

There are genuine objections too: in designated high-risk zones (the highest ZÜRS hazard class), premiums are expensive today and cover can be hard to obtain. Any mandatory scheme must resolve how such locations remain insurable – deductibles, premium caps and an opt-out model (owners must actively decline) are under discussion.

What it would mean for homeowners

• Existing buildings policies would be extended by the natural hazard rider – premiums rise accordingly, moderately to noticeably depending on location.
• Owners who already have the rider would hardly feel a change – except, in time, more stable premiums thanks to the larger risk pool.
• Landlords can allocate the premium to tenants as an operating cost (details here) – so the mandate would reach tenants through service charges as well.

Our advice: don't wait for the law

Heavy rain long ago stopped being a riverside-only problem – a large share of flood damage occurs outside designated flood zones. What makes sense right now:

1. Check your policy: is natural hazard cover included? With what deductible?
2. Cover sewage backup: the classic basement claim – often only covered with a functioning backflow valve.
3. Update the insured value: underinsurance hurts twice in a claim.
