Renting an apartment in Germany as an American

Most people in German cities rent, and the legal framework behind a lease is detailed and fairly protective of tenants. When I lived and worked in Germany, the part that took newcomers longest was not the law but the search itself: in big cities, popular apartments draw many applicants, and landlords pick the file that looks most complete.

This guide covers how a German residential lease is structured, the rent models you will see in contracts, the paperwork landlords request from someone without local history, and the legal steps tied to moving in. For credit checks and deposit limits in detail, see the separate guide on SCHUFA and the Kaution in this series.

The basic deal in a German lease

Section 535 of the Civil Code (BGB) defines the core of every lease. The landlord must hand over the apartment in a condition fit for the agreed use and keep it in that condition for the whole tenancy. The tenant must pay the agreed rent. Everything else in the contract builds on these two duties.

In listings and contracts you will see two rent figures:

• Kaltmiete (cold rent): the base rent for the apartment itself.
• Warmmiete (warm rent): base rent plus monthly advance payments for operating costs, typically including heating and hot water.

Operating costs are settled once a year with a statement. You may receive a refund or a bill for the difference, so budget for the warm rent and keep a margin.

Many German rentals come unfurnished in a stricter sense than Americans expect. An empty apartment may lack light fixtures and sometimes a fitted kitchen. Read the listing for "Einbauküche" (fitted kitchen) and ask what stays in the apartment.

Open-ended or fixed-term

The default German lease runs for an indefinite period. That is the normal case, not a special arrangement.

A fixed-term lease (Zeitmietvertrag) is only allowed in narrow cases under Section 575 BGB. The landlord must intend, at the end of the term, to use the apartment for themselves, their family or household members, to remove or substantially renovate the building, or to rent it to someone obliged to provide services. The landlord must tell you the reason in writing when the contract is signed. If that does not happen, the law treats the lease as open-ended.

Section 575 also gives the tenant a check: from four months before the term ends, you can ask the landlord to confirm within a month whether the reason still exists. If the reply comes late, you can ask for an extension equal to the delay.

Many Americans on assignments of one or two years want certainty about an end date. An open-ended lease still works: you can give notice yourself, and the notice period for tenants is about three months, as described below.

Rent models you will see

German leases usually follow one of three rent patterns.

Ordinary rent with increases up to the local comparative rent. Under Section 558 BGB, a landlord may ask you to agree to an increase up to the "ortsübliche Vergleichsmiete", the usual rent for comparable apartments in the area. The rent must have been unchanged for 15 months at the time the increase takes effect, and a request can be made no earlier than one year after the last increase. A cap also limits how much rent can rise within three years.

Staggered rent (Staffelmiete). Section 557a allows the contract to set future rent amounts in advance. Each step must be shown as a euro amount in the written agreement, and each rent must stay unchanged for at least one year. During a staggered rent, the ordinary increase procedure is excluded. The tenant's right to give notice can be excluded for at most four years from signing. The rent cap rules for tight markets apply to every step.

Index rent (Indexmiete). Section 557b allows rent to follow the consumer price index calculated by the Federal Statistical Office. The rent must stay unchanged for at least a year between adjustments, and the landlord must claim a change in text form, stating the index change and the new rent. The new rent is due from the start of the month after next.

Ask which model applies before you sign, because it decides how your rent changes during a multi-year stay.

Rent caps in tight housing markets

Section 556d BGB lets state governments designate areas with a tight housing market. There, the rent at the start of a new lease may not exceed the local comparative rent by more than 10 percent, with exceptions such as new buildings. Designations are made by state regulation for set periods, so check your city's current status with the state or city housing authority before relying on it.

What landlords ask a newcomer for

Without a German credit history, your file has to do the work. Landlords commonly request:

• A copy of your passport and your visa or residence permit
• An employment contract or recent payslips, or other proof of income
• A self-disclosure form (Mieterselbstauskunft) that the landlord supplies
• A credit report or data copy, where you have one
• A confirmation that you have no rent arrears with your previous landlord

There is no legal list of required documents. Landlords choose what to ask, and you choose what to share, within data protection rules. A short cover letter in simple German, plus English translations of US documents, helps.

The move-in confirmation and registration

Renting and registering are linked by law. Under Section 17 of the Federal Registration Act (BMG), anyone who moves into an apartment must register with the registration office within two weeks of moving in.

Section 19 BMG requires the landlord (Wohnungsgeber) to cooperate. The landlord or someone they authorise must confirm your move-in in writing, or electronically to the authority, within that two-week window. The confirmation contains the landlord's name and address (and the owner's name if different), the move-in date, the apartment address and the names of the people registering.

If the landlord refuses or the confirmation does not arrive in time, you must tell the registration office without delay. The same section makes it illegal to offer an address for registration when nobody actually lives there, so be wary of anyone selling "registration addresses".

Registration then feeds into much of what follows: the tax identification number is issued after a first registration, and banks and employers ask for your registered address. Ask for the move-in confirmation when you sign the lease so you can book a registration appointment quickly.

Subletting and shared flats

Shared flats (Wohngemeinschaft, or WG) and sublets are common entry points for newcomers. Under Section 540 BGB, a tenant may not hand over the use of the apartment to a third party, including subletting, without the landlord's permission.

If you rent a room from a main tenant, ask whether the landlord has agreed to the sublet, and get the arrangement in writing. A sublet without permission puts the main tenant's lease at risk and can leave you without a home at short notice. Also confirm that the main tenant will sign the move-in confirmation you need for registration.

Notice when you leave

German leases end by written notice, and Section 568 BGB requires written form: a signed letter, not an email. Under Section 573c BGB, a tenant can give notice by the third working day of a month, effective at the end of the month after next. That works out to roughly three months.

For landlords the notice periods are longer and rise with the length of the tenancy, and ordinary notice by a landlord requires a legitimate interest. Read your contract for any agreed waiver of notice, which some leases include for a set period.

Notes for Berlin and Munich

Both cities are high-demand rental markets, and demand shapes the search more than the law does. In my time living in Germany the common pattern was clear: be ready to view at short notice, bring a complete paper file to the viewing, and be able to sign and pay the first deposit instalment quickly.

Temporary furnished apartments are widely offered to people arriving for work. They can bridge the first months, but check that the provider will issue the move-in confirmation for registration, and compare the total monthly price with the warm rent of a regular lease.

Before you sign

1. Confirm whether the lease is open-ended or fixed-term, and the written reason if fixed-term.
2. Identify the rent model: ordinary, staggered or index.
3. Note the cold rent, the operating cost advance and what it includes.
4. Check the deposit amount and payment terms.
5. Ask for the move-in confirmation for your registration.
6. Get written permission for any sublet.
7. Keep a signed copy of the contract and a dated record of the apartment's condition.

Common questions

Can a German landlord give me a one-year lease? Only in the cases listed in Section 575 BGB, such as the landlord's own later use, and the reason must be given in writing at signing. Otherwise the lease counts as open-ended.

What is the difference between Kaltmiete and Warmmiete? Kaltmiete is the base rent. Warmmiete adds the monthly advance payments for operating costs, usually including heating, which are settled with a yearly statement.

Does my landlord have to help me register my address? Yes. Section 19 of the Federal Registration Act requires the landlord to confirm your move-in within two weeks. Tell the registration office if the confirmation is refused or late.

Can I sublet my German apartment while I travel? Only with the landlord's permission under Section 540 BGB. Ask in writing before handing the apartment to anyone.
