What Is the Kaution and Why Does It Matter for Expats?
German rental deposit rules, known as **Kaution**, protect landlords while giving tenants strong legal safeguards. New expats often face this upfront cost when signing a lease. Understanding **German rental deposit rules** prevents financial surprises in cities like Berlin or Munich.[1][2]
The **Kaution** covers potential damages or unpaid bills. It must go into a separate account earning interest for you. Courts enforce these rules strictly under §551 BGB.[3]
For expats, this means budgeting €1,200-4,500 depending on location. Ignore landlords demanding more than three months’ cold rent. This guide breaks down every aspect for confident renting.[1][5]
Maximum Kaution Amount: Stick to the 3-Months Kaltmiete Rule
German law caps the **Kaution** at **three months’ Kaltmiete** (cold rent, excluding utilities). Most landlords request this maximum. For a €1,000/month apartment, expect €3,000.[1][2][3]
Kaltmiete excludes Nebenkosten like heating. Furnished rentals may justify slightly higher amounts for furniture risks. However, anything over three months is illegal—challenge it immediately.[5]
In major cities, averages vary: Berlin/Munich €2,400-4,500; smaller towns €1,200-2,400. Creditworthy tenants sometimes negotiate two months. Always check your lease.[1]
Expats: Verify before signing. Use §551 BGB as your reference.[3]
How to Pay Your Kaution: Cash, Transfer, or Alternatives?
Pay the **Kaution** via bank transfer to a dedicated account—never cash unless documented. Landlords cannot access it without cause. Do this 1-2 weeks before move-in.[1][2]
Expats short on funds have options. Split into three parts: 1/3 before lease start, 1/3 after one month, 1/3 after two months. Lease start is move-in readiness, not signing date.[2]
Prefer **Kaution insurance** (Mietkautionversicherung) at 3-7% annual premium. Providers like Kautionskasse or Allianz issue guarantees landlords accept. No lump sum needed, ideal for newcomers.[1][3]
Avoid paying before viewing the apartment. Scams target expats with fake listings. Document everything.[2]
Übergabeprotokoll Explained: Your Key to Deposit Protection
The **Übergabeprotokoll** is the handover protocol documenting the apartment’s condition at move-in and move-out. It lists damages, meter readings, and inventory. Sign it with photos for proof.[1][2]
At move-in, note existing issues like wall scratches. This prevents landlords blaming you later. Both parties sign; keep copies.[2]
At move-out, compare against the original. Unresolved items from the protocol cannot be deducted. Without it, courts favor tenants.[1]
Expats: Insist on this. It resolves 90% of disputes. For templates, see Deutscher Mieterbund.[2]
Timeline for Kaution Return: Expect 3-6 Months, Not Longer
Landlords must return your **Kaution** within **3-6 months** after move-out. This allows inspections, repairs, and final Nebenkostenabrechnung (utility settlement).[1][4]
Process: Hand over keys, sign Übergabeprotokoll, receive Betriebskostenabrechnung within 12 months. Pay extras promptly for faster return.[2]
Partial refunds apply if issues resolve early. Full hold only for ongoing claims. Courts deem over 6-12 months unreasonable.[2][4]
Track via email. No response? Send formal letters. This timeline applies nationwide.[1]
Can Landlords Keep Kaution for Normal Wear and Tear?
No, landlords cannot deduct for **normal wear and tear** (Normale Abnutzung). Faded paint or minor scratches from daily use stay on them. Only tenant-caused damages qualify.[1][2]
Allowed deductions: Excessive wall holes, broken appliances from misuse, carpet stains needing pro cleaning, unpaid rent/utilities. Invoices must prove real costs—no estimates.[2]
Example: Hanging pictures? Small holes okay. Punching walls? Deductible. Get detailed bills; challenge overcharges.[1]
Expats often face aggressive claims. Compare Übergabeprotokoll and photos. Tenants win most disputes.[2]
What If Landlord Refuses to Return Your Deposit?
If your landlord won’t return the **Kaution**, send a registered letter (Einschreiben mit Rückschein) demanding it within 14 days. Reference §551 BGB and documents.[3]
Escalate to Mieterverein (tenants’ association, €50-100/year membership) or local court (Mahnbescheid, low cost). Success rate exceeds 80% for valid claims.[2]
Don’t withhold rent—illegal and weakens your case. For disputes, contact Verbraucherzentrale. Keep all records.[1]
Edge case: International move-out. Provide forwarding address early. Banks can forward interest.[2]
Can You Withhold Last Month’s Rent as Kaution?
No, never withhold last month’s rent instead of **Kaution**. Courts view this as breach, allowing eviction. Pay full rent; reclaim deposit separately.[2]
Landlords hold Kaution legally. Withholding risks Mietminderung claims or lawsuits. Always pay via transfer for records.[1]
Alternative: Negotiate early release if pristine condition. Document agreement in writing. Expats avoid this mistake by joining Mieterbund pre-lease.[2]
Consequence: Late rent damages SCHUFA score, blocking future rentals.[1]
Repairs and Deductions: What Landlords Can (and Can’t) Charge
Landlords deduct only **actual repair costs** with invoices—no flat fees. You can fix minor issues yourself or hire your own pro. They can’t mandate theirs.[2]
Common deductions: Wall repairs (€20-50/m²), carpet cleaning (€2-4/m²), fixture replacements. Normal wear like light bulbs? Landlord’s duty.[1][2]
Step-by-step dispute: 1) Request invoices. 2) Verify against protocol. 3) Propose your fixes. 4) Escalate if needed. Save 50-70% this way.[2]
Expats: For furnished flats, clarify furniture wear upfront. See [INTERNAL: Furnished Apartment Guide] for tips.[1]
Kaution Mistakes Expats Make (and How to Avoid Them)
Common pitfalls: Paying cash without receipt, skipping Übergabeprotokoll, ignoring Nebenkostenabrechnungen. These lead to full deposit losses.[1][2]
Timeline tip: Final bills arrive up to 12 months post-move-out—budget accordingly. Use apps like EasyTenant for tracking.[2]
Pro advice: Join Berliner Mieterverein (€80/year) for free legal aid. Read lease Kaution clause first. Link to [INTERNAL: German Lease Checklist].[3]
Success scenario: Documented protocol + photos = full refund in 3 months. Stay protected.[1]
