When something breaks in a rented flat in Germany, tenants often wonder: is this my problem or the landlord's? The short answer is that German law puts the primary maintenance obligation firmly on the landlord. Under § 535 BGB, landlords are legally required to keep the property in a condition fit for its intended use throughout the tenancy. Tenants, however, are responsible for damage they cause through their own negligence or misuse — and, under certain contract conditions, for a narrow category of minor repairs known as Kleinreparaturen. Knowing where this line sits can save you money and prevent disputes.
Key takeaways
- Landlords must maintain the property in habitable condition under § 535 BGB. This includes structural repairs, heating, plumbing, electrics, roof, and windows.
- Tenants are responsible for damage they cause through negligence or misuse — not for normal wear and tear.
- Tenants must report defects in writing immediately. Failure to report can make the tenant liable for consequential damage.
- A Kleinreparaturklausel can only oblige tenants to pay for minor repairs if it specifies both a per-incident cap (typically 75–100 EUR) and an annual cap (typically 200–300 EUR). Without both limits, the clause is invalid.
- Most cosmetic repair clauses (Schönheitsreparaturen) in standard-form contracts are invalid. Check yours before spending money on painting.
- Mould disputes are common. Who bears responsibility depends on whether the cause is structural (landlord) or ventilation-related (tenant). Always document and report in writing.
Overview: the legal starting point
German residential tenancy law is built around a clear principle: the landlord grants the tenant the use of the property in return for rent, and in order to deliver on that promise, the landlord must keep the property in a condition fit for that use throughout the tenancy. This obligation is set out in § 535 BGB (Bürgerliches Gesetzbuch, Germany's civil code) and it cannot be contracted away in standard-form leases.
Tenants, by contrast, are not general maintenance contractors for the property they rent. Their responsibilities are more limited: they must treat the property with reasonable care, not cause damage through negligence or misuse, report defects promptly, and — only if a valid contractual clause exists — pay for a narrow range of minor repairs.
Two contractual clauses frequently appear in German leases and frequently cause confusion: the Kleinreparaturklausel, which attempts to shift small repair costs to the tenant, and the Schönheitsreparaturen clause, which attempts to require tenants to carry out cosmetic work at move-out. Both are only valid under strict conditions. Both are frequently drafted in ways that make them unenforceable. Understanding them is essential before signing any lease or spending money on repairs.
ℹ Info: The rules in this guide apply to standard residential leases. Some rules differ for furnished short-term rentals, subletting arrangements, and lodging in the landlord's own home. If you are unsure which category applies to you, check your contract or seek advice from a Mieterverein.
What landlords must maintain
Under § 535 BGB, the landlord is obliged to hand over the property in a condition fit for the agreed use and to maintain it in that condition for the duration of the tenancy. This is a continuing obligation, not a one-off duty. It covers everything necessary for the property to function as a home.
The following categories fall squarely within landlord responsibility:
| Component | Landlord's obligation | Notes |
|---|---|---|
| Structural fabric | Roof, external walls, floors, load-bearing elements | Any defect that compromises structural integrity or weather-tightness is entirely the landlord's responsibility. |
| Heating system | Boiler, radiators, underfloor heating, and associated pipework | Failure of heating in winter is a serious defect entitling tenants to rent reduction under § 536 BGB. |
| Plumbing and water supply | Water pipes, waste pipes, water pressure, hot water system | Includes leaks arising from the building's own pipework. Tenant-caused leaks (e.g. from misuse of fixtures) are a different matter. |
| Electrical installation | Fixed wiring, fuse box, sockets, and permanently installed fixtures | The landlord must ensure the installation is safe and functional. Replacing a tenant's blown lightbulb is not a landlord obligation; repairing a faulty circuit is. |
| Windows and external doors | Frames, seals, glazing, locks (structural function) | Window handles are often listed in Kleinreparaturklausel clauses — but only if the clause is valid (see below). |
| Common areas and building services | Stairwells, lifts, shared laundry, entrance lighting | Shared services are a landlord obligation. Costs may be passed on through Nebenkosten where legally permitted. |
The test is practical: if a defect prevents the tenant from using the property as a home in the agreed way, the landlord must repair it. This includes restoring function, not merely patching symptoms. A recurring damp problem that is repeatedly treated with sealant but never structurally resolved does not meet the landlord's obligation.
💡 Tip: If a landlord fails to carry out a repair within a reasonable time after being notified in writing, tenants may be entitled to reduce rent under § 536 BGB (Mietminderung) in proportion to the impairment. Courts have published benchmark reduction percentages for common defects. Consult a Mieterverein before applying any reduction unilaterally.
What tenants are responsible for
Tenants are not responsible for defects that arise through normal use or through the property's own aging. They are responsible for damage caused by their own actions, negligence, or misuse. Three categories of responsibility apply.
1. Damage caused by negligence or misuse
If a tenant breaks something through careless or improper use, the cost falls on the tenant. This is basic civil liability under § 280 BGB, independent of any contractual clause.
Common examples:
- A dropped object cracks a tiled floor or smashes a bathroom fixture.
- A door is repeatedly slammed and the frame or mechanism is damaged.
- The shower or bath area is not sealed properly by the tenant and water penetrates, damaging the floor or ceiling below.
- A tap is overtightened and the washer or valve is stripped.
- Walls are drilled carelessly and pipes or cables are damaged.
Normal wear and tear is explicitly excluded. Scuffed skirting boards, faded paint, minor marks on walls from normal living, and worn floor coverings from years of use are not the tenant's liability. The distinction between negligent damage and normal wear can be contested, and the Übergabeprotokoll (handover protocol) at move-in and move-out is the key evidence document when disputes arise.
2. Duty to report defects promptly
Tenants have a legal duty to inform the landlord of defects without undue delay (§ 536c BGB). This is not a courtesy — it is a legal obligation. If a tenant notices a defect and fails to report it, and that failure allows the defect to worsen (for example, a small water leak becomes a large one), the tenant may be held liable for the consequential damage even if the original defect was the landlord's responsibility.
Always report defects in writing. A WhatsApp message is better than nothing, but a written email or letter provides cleaner evidence. State the defect precisely, give the date you discovered it, and request a response with a repair timeline.
⚠Warning: Under § 536c(2) BGB, a tenant who fails to report a defect loses their right to rent reduction (Mietminderung) for the period during which notification was omitted, and may be held liable for any damage the landlord could have prevented had they known about the defect. Prompt, written reporting protects you.
3. Minor repairs under a valid Kleinreparaturklausel
If your lease contains a valid Kleinreparaturklausel (minor repair clause), you may be required to pay for certain small repairs up to a financial limit. This is a contractual obligation, not a statutory one. Without a valid clause, the landlord pays for all repairs, however small.
The full rules on what makes a Kleinreparaturklausel valid — and which items it can cover — are explained in the next section.
The Kleinreparaturklausel explained
The Kleinreparaturklausel is a contractual clause that shifts the cost of minor repairs from the landlord to the tenant. It is permitted under German law, but only within strict limits established by the Bundesgerichtshof (BGH, Germany's Federal Court of Justice). A clause that exceeds those limits is invalid, and an invalid clause is treated as if it does not exist — the landlord bears all repair costs.
What makes the clause valid?
A Kleinreparaturklausel in a standard-form (pre-printed) contract is only legally enforceable if it meets all of the following conditions:
- Per-incident cap: The clause must specify a maximum cost per individual repair. The BGH-accepted range is approximately 75–100 EUR per incident. Clauses setting higher per-incident limits are generally struck down.
- Annual cap: The clause must also specify a maximum total amount the tenant can be required to pay in any twelve-month period. The accepted range is approximately 200–300 EUR per year. A clause without an annual cap is invalid regardless of the per-incident limit.
- Both caps must be present: A clause that only states one limit (e.g. "up to 100 EUR per repair" with no annual cap) is invalid. Both limits are required for the clause to be enforceable in a standard-form contract.
- Restricted to items in frequent tenant contact: The clause can only cover items that tenants regularly handle and that are subject to wear from direct use. It cannot extend to structural components or the building's core systems.
Items typically covered by a valid Kleinreparaturklausel
| Item | Included? | Notes |
|---|---|---|
| Door handles and hinges | Yes | Frequently handled — typically covered. |
| Tap washers and cartridges | Yes | Small maintenance items in frequent use — typically covered. |
| Window and door locks (internal mechanism) | Yes | Lock mechanisms worn through use — typically covered if per the clause wording. |
| Light switches and socket covers | Sometimes | Depends on clause wording. Underlying wiring is always the landlord's responsibility. |
| Light fittings (surface-mounted, tenant-operated) | Sometimes | Only items in direct tenant contact. Integrated or complex fixtures are less clear-cut. |
| Toilet flush mechanism | Sometimes | Internal flush components are a grey area. The cistern structure itself is the landlord's. |
| Boiler, central heating, roof, pipes | No | These are structural or system components. The Kleinreparaturklausel cannot cover them. |
⚠Warning: If your contract's Kleinreparaturklausel is missing either the per-incident cap or the annual cap, or if either figure is higher than courts have accepted, the entire clause is invalid. You owe nothing under it. Courts do not "fix" invalid clauses by substituting acceptable figures — they strike the clause entirely.
What if the clause is individually negotiated?
The strict BGH limits on per-incident and annual caps apply to standard-form (pre-printed) contracts, which are the vast majority of German leases. If a clause was individually negotiated between landlord and tenant (Individualvereinbarung), different rules may apply and higher limits may be permissible. In practice, genuine individual negotiation of repair clauses is rare. If in doubt, assume the standard rules apply and seek advice.
Schönheitsreparaturen: cosmetic repairs
Many German leases include a Schönheitsreparaturen clause requiring the tenant to carry out cosmetic repairs — typically repainting walls and ceilings — either during or at the end of the tenancy. These clauses are common, but a large proportion of them are legally invalid.
The BGH has, in a series of landmark decisions, struck down the most widespread types of cosmetic repair clauses as unreasonably burdensome under § 307 BGB. Before spending money on painting or other cosmetic work, check whether your clause falls into one of the following invalid categories.
Invalid clause types
- Rigid interval clauses (Fristenklauseln): Clauses that require repainting at fixed intervals (e.g. "every three years for kitchen, every five years for living rooms") regardless of actual condition are invalid. The BGH ruled these too broadly burdensome in 2015 (BGH VIII ZR 185/14).
- Clauses that apply when the flat was received unrenovated: If you received the flat in an unrenovated condition at move-in, any obligation to hand it back in a renovated condition is invalid. You cannot be required to leave the property in better condition than you received it (BGH VIII ZR 361/03).
- "White-wash" clauses: Clauses that require tenants to repaint specifically in white, light, or neutral colours are invalid because they restrict the tenant's choice and go beyond mere maintenance (BGH VIII ZR 166/08).
- Clauses combining invalid elements: If a clause bundles together a rigid interval with another invalid requirement, the whole clause falls — not just the offending part.
When cosmetic repair clauses can be valid
A Schönheitsreparaturen clause can be valid if it:
- Uses flexible intervals tied to actual need, not fixed timeframes ("when necessary" or "as required by condition");
- Applies only if the tenant received the flat in a renovated condition at move-in; and
- Does not restrict colour choice in ways that go beyond maintaining a neutral, lettable condition.
Even a valid clause only covers cosmetic work: painting, wallpapering, and similar surface treatments. It cannot require the tenant to replace flooring, carry out structural repairs, or fix fixtures.
💡 Tip: Before you arrange and pay for any painting or redecorating at move-out, have your clause assessed by a Mieterverein or solicitor. If the clause is invalid, the landlord cannot require the work — and cannot deduct painting costs from your deposit. Many tenants spend money on cosmetic work they are not legally required to do.
What to do when something breaks
When a defect appears in the property — whether it is a structural issue, a failing appliance, or a minor malfunction — the correct process matters. Following it protects your rights and ensures the landlord cannot later claim you caused the damage through inaction.
Step 1: Report in writing immediately
Notify the landlord or property manager in writing as soon as you discover the problem. Describe the defect precisely: what is broken, where it is, when you noticed it, and what effect it is having on your use of the property. Email is usually sufficient for evidence purposes, but a formal letter sent by tracked post provides stronger documentation if a dispute later arises.
State a reasonable deadline for repair. For a broken heating system in winter, that may be 24–48 hours. For a non-urgent defect such as a dripping tap, one to two weeks is generally considered reasonable.
Step 2: Keep copies of everything
Save all written communications with the landlord. Take dated photographs of the defect as soon as you report it and again at any later stages. If the landlord visits to inspect or carry out a repair, confirm the outcome in writing afterwards ("Following your visit on [date], the boiler was serviced but the fault has recurred..."). This creates a clear paper trail.
Step 3: Do not carry out repairs yourself without consent
Unless you are dealing with a genuine emergency (see the next section), do not arrange or carry out repairs without the landlord's prior written consent. Unauthorised repairs, however well-intentioned, can result in the landlord refusing to reimburse you — and in some cases, claiming you caused further damage. Always obtain written agreement before instructing a tradesperson at the landlord's expense.
ℹ Info: If the landlord does not respond to your written report within a reasonable time, send a follow-up letter setting a firm deadline and stating that you will consider further steps if the repair is not completed. This establishes that the landlord was on notice. If the defect significantly reduces your use of the flat, consult a Mieterverein about your right to Mietminderung (rent reduction) under § 536 BGB.
Emergency repairs
Occasionally, a defect requires immediate action and the landlord cannot be reached in time to authorise a repair. In these circumstances, German law allows tenants to arrange emergency repairs themselves and seek reimbursement from the landlord. The right is narrow and is tied to genuine emergencies — not inconveniences.
When emergency self-help is permitted
The following situations typically justify emergency action by the tenant:
- A burst pipe is flooding the flat or building and water cannot be shut off.
- Complete heating failure in winter, with temperatures in the flat falling to a level that poses a health risk.
- A gas leak that requires immediate professional intervention.
- A security failure (broken front door lock) that leaves the property unsecured.
How to proceed
- Attempt to contact the landlord first. Call, email, and if available, use any emergency contact number in the lease. Document every attempt with timestamps.
- Take photographs before, during, and after the repair. The state of the defect, the work carried out, and the result should all be documented.
- Instruct a qualified, reputable tradesperson. Use only what is necessary to address the emergency — do not extend the scope beyond the immediate problem.
- Keep all invoices and receipts. You will need these to claim reimbursement.
- Notify the landlord in writing immediately after the repair. Explain what happened, what was done, and the cost. Request reimbursement in writing.
⚠Warning: Self-help repair rights are limited to genuine emergencies where the landlord cannot be reached in time and delay would cause significant damage. Using this right in non-emergency situations — for example, to fix a slow-draining sink without prior landlord contact — is unlikely to be reimbursed and could expose you to counterclaims. When in doubt, wait and document.
Mould and damp
Mould disputes are among the most common and most contested issues in German residential tenancy. The question of who is responsible depends on the cause — and establishing the cause is often the entire battleground.
When the landlord is responsible
If mould results from a structural defect in the building, the landlord is responsible. Structural causes include:
- Damp ingress through external walls, roof, or basement;
- Insufficient wall insulation causing cold bridges (Kältebrücken) where moisture condenses;
- Missing or defective vapour barriers;
- Defective window seals allowing water ingress;
- Inadequate mechanical ventilation in windowless rooms such as bathrooms or kitchens.
In these cases, mould is a defect under § 536 BGB. The landlord must remediate the mould and address the underlying structural cause. The tenant may be entitled to rent reduction for the period during which the defect persists.
When the tenant is responsible
If mould results from how the tenant uses the flat, the tenant bears responsibility. Tenant-caused mould typically arises from:
- Insufficient ventilation — not airing the flat regularly, particularly after cooking, showering, or drying clothes indoors;
- Keeping interior temperature too low while maintaining normal occupancy and generating moisture;
- Placing large items of furniture directly against external walls, preventing air circulation;
- Drying laundry indoors without adequate ventilation.
Why disputes are so common
Mould frequently appears in locations where both explanations are plausible — external corners of rooms, behind wardrobes, around window reveals. Landlords routinely attribute mould to tenant behaviour. Tenants routinely point to cold walls or condensation on windows. Neither side has a monopoly on being right, and expert opinions are frequently commissioned on both sides.
The practical implication for tenants is clear: keep written records of your ventilation habits, maintain adequate heating (courts expect a minimum of around 19–20°C in living areas during winter), and report any mould or damp to the landlord in writing as soon as you notice it. If you suspect a structural cause, ask the landlord to investigate. If they refuse, document the refusal.
💡 Tip: An inexpensive humidity meter (Hygrometer) placed in affected rooms gives you objective data on indoor humidity levels. Courts and experts routinely accept such readings as evidence. Keeping a log of readings alongside records of ventilation and heating gives you a strong factual basis if a dispute escalates.
ℹ Info: Mould that poses a health risk may constitute a serious defect entitling the tenant to extraordinary termination under § 543 BGB in extreme cases. This is a high threshold. The defect must be severe, persistent, and unresolved after the landlord has been formally notified and given a reasonable deadline to act. Seek legal advice before terminating on this basis.
