Water damage in a shared flat happens faster than you might think. The washing machine overflows, a hose bursts behind the cupboard, and suddenly there is water in the hallway or the flat below is wet. Water damage in a shared flat almost always involves several cost items with different responsibilities. This guide explains which insurance pays for what and where liability insurance (Haftpflichtversicherung) comes in.
Short answer: For your own belongings such as furniture, a laptop or clothing, contents insurance (Hausratversicherung) is usually responsible, provided that water damage from pipes (Leitungswasser) is covered. Damage to the flat of your neighbours or your landlord is checked under the private liability insurance (Privathaftpflichtversicherung) of the person who caused it, and only if there is fault. Damage to the building itself is usually covered by the landlord’s building insurance. Stand: October 2026. The policy terms are decisive.
Key Points at a Glance
- Your own belongings are covered by contents insurance, and damage to other people’s property by liability insurance.
- Liability insurance usually pays only if fault can be proven against the person who caused the damage.
- Building damage, such as to ceilings, floors and pipes, is usually the landlord’s responsibility and falls under the landlord’s building insurance.
- You must report the damage to your landlord without delay, otherwise this may later count against you.
- Document the damage immediately with photos and note when and how it happened.
Which Insurance Pays for Which Damage?
When water damage occurs in a shared flat, it is worth looking at each cost item separately. A single insurance policy rarely covers everything. Part of the damage affects your own belongings, another part affects the property of your flatmates, neighbours or landlord, and further costs arise on the building itself.
| Cost item | Usually responsible | What you should pay attention to |
|---|---|---|
| Your own furniture, laptop, clothing | Contents insurance | Whether water damage from pipes is covered and what the deductible is |
| Damage to the flat below you | Private liability insurance of the person responsible | Fault and coverage limit |
| Damage to ceiling, floor or pipes | Landlord’s building insurance | Report the damage to the landlord without delay |
| Damage caused by a flatmate | Flatmate’s liability insurance, if insured | Who caused the damage and how it happened |
When Does Liability Insurance Pay for Water Damage?
Private liability insurance covers damage that you cause to a third party, whether negligently or intentionally. This follows from the general duty to pay damages under § 823 of the German Civil Code (Bürgerliches Gesetzbuch, BGB). The decisive question is therefore whether you can be blamed for the damage. If you connected a washing machine properly and a hose suddenly tore due to material fatigue, there is no classic fault. If, however, you had not checked the inlet hose for months although it was visibly brittle, you could be accused of negligence.
Liability insurance then pays for damage to someone else’s property, for example to the furniture or floors of the flat below. It does not pay for your own belongings, which is what contents insurance is for. The guide Student Insurance: Liability, Contents and Accident Cover also explains the difference between the two policies.
What Does Contents Insurance Pay for Pipe Water Damage?
Water damage from pipes is often covered by contents insurance. The terms differ in detail, though. Some policies limit cover to damage to items inside the flat, or they apply a deductible. It also matters whether the damage was caused by a sudden burst pipe or by slow seepage. Slow damage that goes unnoticed for a long time is excluded in many policies or only partly covered.

How Do You Act as a Tenant When Water Escapes?
First comes damage limitation. Shut off the water supply if this is safe to do, and switch off the power in the affected areas if there is a lot of water. Do not repair the pipe or the building fabric yourself before your landlord has been informed. Document everything with photos and videos, including the spot where the water escaped.
Then you must report the defect. Under § 536c BGB, a tenant must notify the landlord without delay of any defect that occurs during the tenancy. If you fail to do so, you risk disadvantages, for example if the damage grows because of the delay. Also report the damage to your own contents insurance and, if a third party is affected, to your liability insurance.
What Does a Calculation Example Look Like?
Calculation example (assumption): In a shared flat, water escapes from a flatmate’s washing machine. The damage to the flat below is €3,000, and your laptop and some furniture are damaged to the amount of €800. The liability insurance of the person responsible pays the €3,000, provided that fault can be attributed to them. Your own €800 is reimbursed by contents insurance, minus a deductible (Selbstbeteiligung) of €150. You therefore receive €650. If you have no contents insurance, the loss stays with you.
The example shows why both insurances belong together. If you have only liability insurance, your own belongings remain unprotected. If you have only contents insurance, you pay for damage to someone else’s property yourself if the person responsible is not insured.
What Happens If a Flatmate Causes the Damage?
If a flatmate caused the water damage through negligence, they can be liable for it. This affects both damage to the flat and damage to your flatmates’ belongings. In practice, the flatmate’s liability insurance settles the compensation. Whether this flatmate has liability insurance should be clarified early on. Many shared-flat arrangements contain no rule on this, so a short agreement when moving in is worthwhile.
Frequently Asked Questions
Do I have to report water damage to my landlord?
Yes, and promptly. This follows from the duty to report defects under § 536c BGB. The report should be made in writing and include photos. This way you can prove when you reported the damage and what condition the flat was in.
Does the landlord pay for my furniture?
Usually not. The landlord’s building insurance covers the building, not your furnishings. You are responsible for furniture, electronics and clothing yourself, and that is what contents insurance is for.
Does my parents’ liability insurance also apply in a shared flat?
That depends on the policy and on your living situation. Family liability insurance often covers students only up to a certain limit, for example as long as they still live in their parents’ household or are in initial training. In your own shared flat, this is often no longer the case. Check in writing whether you are still covered.
Do I have to have the damage repaired straight away?
No. First speak to your landlord and the insurer. If you repair something without agreement, you may destroy evidence that matters for settling the claim. In acute danger, for example a risk of electric shock, an exception applies. In that case, secure the danger spot first.
What to Do Now
- Shut off the water supply and secure the spot where the water escapes.
- Document the damage with photos and videos and note the date and time.
- Report the damage in writing to your landlord and to your contents insurer.
- If third parties are affected, inform your liability insurer or the insurer of the person responsible.
- Agree early in the shared flat who has which insurance, so the next damage is settled faster.
