Moving to Germany for a new job, study program, or simply a change of scenery? If you’re renting a mid-term home (1–12 months), understanding how German rental contracts work is absolutely essential. Rental laws here are different from what you might be used to, and not knowing the rules can lead to stress, misunderstandings, or even legal trouble.
This guide breaks down everything you need to know about German rental agreements, especially if you’re an expat, digital nomad, or professional staying temporarily through Wunderflats. Let’s walk through the key points in clear, simple terms.
1. Overview of German Rental Contracts
Why Rental Contracts Matter
A rental contract (Mietvertrag) in Germany is a binding legal agreement. It protects both you and the landlord by clearly defining your rights and responsibilities. It spells out what’s included in the rent, how long you can stay, and what happens if something goes wrong.
Importantly, this document is also necessary for many administrative tasks in Germany. For example, registering your address (Anmeldung), applying for a residence permit, or opening a bank account. A clear and well-drafted contract saves you time, stress, and potential costs.
Fixed-Term vs. Open-Ended Contracts
Germany distinguishes between:
- Open-ended contracts: ongoing agreements that continue until you or the landlord gives notice. By law, tenants can always terminate open-ended contracts with a notice period of 3 months (§ 573c BGB), regardless of what the contract states.
- Fixed-term contracts: agreements with a defined start and end date. These are more common in furnished, mid-term rentals through platforms like Wunderflats.
In fixed-term leases, you generally cannot leave early unless the contract allows for termination or you and the landlord agree to end it. Make sure you know the duration and whether it’s extendable if your plans change.
Furnished vs. Unfurnished
In Germany, unfurnished often means completely empty (no kitchen, lights, or curtains). Luckily, mid-term rentals via Wunderflats are typically furnished, including essential furniture, kitchenware, appliances, and even towels.
Still, check the inventory list (Inventarliste) in the contract or ask for one if it’s not included. This helps you know what’s provided and protects you from being held responsible for missing or damaged items.
What Must Be Included in the Contract
German law requires certain key elements in every rental agreement. If anything is missing or unclear, request clarification before signing.
a) Landlord and Tenant Information
The full name, address, and contact details of both parties must be included. If you’re dealing with a property manager or agency, they should also be listed.
b) Address and Property Description
This includes:
- Full postal address
- Size of the apartment (in square meters)
- Number of rooms
- Details on balcony, storage, basement, or shared facilities
If any specific amenities are part of the agreement (such as parking spaces or access to a laundry room) this should be clearly stated.
c) Duration of the Rental
For fixed-term leases, your contract must specify:
- Start and end dates
- Any extension or renewal conditions
- Penalties (if any) for overstaying
Keep in mind that tenants do not have an automatic right to renew a fixed-term lease.
If your lease is longer than 1 year, German law requires a written agreement (§ 550 BGB). Otherwise, the contract is treated as open-ended.
d) Rent Details – Kaltmiete and Nebenkosten
Rent is typically broken down into:
- Kaltmiete (cold rent): the base rent for using the property.
- Nebenkosten (additional costs): include building maintenance, water, heating, waste collection, and building insurance.
When combined, these form the Warmmiete (total rent). Sometimes internet, electricity, or other utilities are included, but not always, so make sure you ask and get clarity in writing.
e) Security Deposit (Kaution)
Landlords in Germany can ask for a maximum of three months’ cold rent as a security deposit. It must be held in a separate escrow account, and you’re entitled to interest earned.
The landlord can deduct from your deposit for:
- Unpaid rent or utility bills
- Damage beyond normal wear and tear
- Missing items listed in the inventory
Return of the deposit can legally take up to six months, though it often happens sooner if all obligations are met.
Per § 551 BGB, the deposit must be held in a separate, interest-bearing escrow account. The landlord cannot use or access it during the tenancy.
f) Utility and Service Costs
Ask if the rent includes:
- Electricity
- Internet and TV
- GEZ fee or Rundfunkbeitrag (broadcasting fee). This applies per household, not per person, and is legally required even if you don’t use TV or radio)
- Cleaning services
- Snow removal or stairwell cleaning (common in shared buildings)
If you’re responsible for setting up or paying any of these separately, plan accordingly.
Be aware of the difference between:
- Nebenkostenvorauszahlung: Monthly prepayments that must be reconciled yearly.
- Nebenkostenpauschale: A flat fee with no reconciliation or refund, even if actual costs are lower.
Always clarify which applies to your lease.
If you pay monthly advances for utilities, your landlord is legally required to issue an annual statement reconciling actual costs (§ 556 BGB). Overpayments must be refunded, and you can dispute inaccurate charges.
Clauses to Read Carefully
Contracts may contain specific rules that vary from landlord to landlord. Don’t skip the fine print and watch for:
Cancellation and Early Termination
Fixed-term leases usually don’t allow early termination, but some offer a break clause or early exit policy. If you might leave early, ask if you can suggest a replacement tenant or pay a termination fee.
Deposit Return Conditions
Some contracts require you to professionally clean the property at move-out, or your deposit may be reduced. Others allow the landlord to hold the deposit longer to wait for utility bills or repairs. Know what to expect.
Rules for Subletting and Guests
Under § 540 BGB, tenants may request to sublet part of the apartment. Landlords may not arbitrarily deny this request unless they have a valid reason. Full subletting or Airbnb-type use usually requires explicit approval.
Cleaning Obligations
Check if there’s a regular cleaning requirement, especially in serviced apartments. Some landlords expect monthly professional cleaning during your stay.
House Rules (Hausordnung)
This may include rules about:
- Quiet hours (typically 10 PM–6 AM, and all day on Sundays/holidays)
- Smoking
- Pets
- Use of common areas
- Garbage disposal schedules
Violating house rules can result in complaints from neighbors or even termination.
Kleinreparaturklausel (Small Repairs Clause)
Landlords can include a rule in the contract saying tenants are responsible for small repairs (like fixing a leaky faucet or a broken door handle). But there are limits:
- Tenants can only be asked to pay up to €75–100 per repair
- The total amount per year is usually limited to €200–300
If the contract asks the tenant to pay more than these limits, that part of the contract is not legally valid.
Your Rights as a Tenant
Germany has strong tenant protections even for international renters.
Anmeldung: Right to Register Your Address
You must register your address (Anmeldung) within 14 days of moving in (§ 17 BMG). Your landlord is legally obligated to provide a Wohnungsgeberbestätigung within this period (§ 19 BMG). Landlords can be fined for failing to provide it (§ 54 BMG).
Written Rental Contract
Always insist on a written contract, even if renting for a short time. This protects both parties and is legally required for fixed-term agreements.
Privacy and Notice
Your landlord cannot enter the property without permission or proper notice, usually at least 24 hours, and only for valid reasons (e.g., repairs, inspections).
Protection from Unfair Clauses
German courts have struck down many unfair rental terms. For example:
- Excessive final cleaning fees
- Mandatory repainting regardless of condition
- Unreasonable penalties
- Early cancellation without valid justification
- Waiving statutory notice rights
If something in the contract feels “off,” consult a tenant association or legal advisor.
What to Clarify Before Signing
Before you sign anything:
- Is Internet Included?
If yes, ask about the speed and reliability. If no, setting up service can take weeks. - Are All Costs Included in the Rent?
Electricity, heating, building fees—get a detailed list. - Are There Shared Areas?
Confirm access to laundry, storage, and other common areas—and who cleans them. - What Happens in Case of Damage?
Normal wear is expected, but find out who pays for what. Is insurance included? - Are Pets or Smoking Allowed?
If you’re planning to bring a pet, make sure the lease allows it. Most apartments are strictly non-smoking indoors.
Tips for International Tenants
A few extra steps can save you major hassle down the line:
Get the Contract Translated
If your German isn’t fluent, consider a certified translator or legal review. Even basic online translations (e.g., DeepL) can help flag confusing clauses.
Keep Everything in Writing
This includes contract negotiations, maintenance requests, and move-out agreements. Save emails and message threads; you may need them later.
Use a Handover Protocol
When you move in or out, request a handover document (Übergabeprotokoll). This lists the apartment’s condition, meter readings, and keys provided.
It’s your proof against damage claims or lost deposits.
Know the Deposit Return Timeline
German landlords may wait up to 6 months to return the deposit, especially if bills are pending. Be patient, but if it drags on without updates, follow up in writing.
Liability insurance (Haftpflichtversicherung)
Recommended but not mandatory
Consider getting personal liability insurance (Haftpflichtversicherung). It’s common in Germany and protects you from costs if you accidentally damage the property or cause harm to others.
