Renting in Germany - tenants' rights, obligations and protection

11 July 2025

The German residential rental market is a system where every party is protected by law, but at the same time, also bound by strict obligations. Rent increases, eviction, rent reductions — all these actions require the following of clear procedures. Not knowing or ignoring the rules will turn even a justified claim into null and void, and can result in unforeseen expenses. We will help you understand how tenancy law works in Germany.

Rules for changing the rent in a tenancy agreement in Germany

Rent increases by law in Germany

In Germany, tenancy laws are regulated by the Civil Code (BGB), and any rent increase must comply with strictly defined conditions. There are three main ways to change the rental price:

Index-linked rent increase - linking the rent to the official consumer price index;
Graduated rent — a step-by-step increase in the rent agreed in advance in the contract;
Standard rent increase — This is only possible if there are no specific terms in the contract and within the permitted limits: no more than 15–20% over three years, and no sooner than one year after the previous increase.

Below we will examine each of these options in detail.

Index-linked rent review

Index-linked price adjustment (index-linked rent in accordance with section 557b of the Civil Code (BGB)) means that the rental price rises/falls in line with the Consumer Price Index. A price change on this basis is possible once every 12 months and does not require the tenant's consent, but must be provided in writing.

If your tenancy agreement is based on an index-linked rent (Indexmiete), you can find the data in the table. Destatis (2020 base = 100). This is the basis for the lawful recalculation of the rent.

Example calculation of the rent increase index in Germany:
The index for the month in which the contract was signed (e.g. May 2024 = 119.3) is compared with the current index (May 2025 = 121.8). Calculate the percentage price increase: ≈2.1%.

This amount can be used to increase the net rent – but only once every 12 months and after written notification, as required by § 557b BGB.

Such a pricing formula does not suit all owners, and some prefer to fix the growth schedule in advance.

Graduated rent increase

Differential rentGraduated rent § 557a BGB) assumes that the dates and amounts of the increases are known in advance. Price changes are possible once a year. A specific amount must be fixed, rather than the percentage of the increase. No other price increases are permitted during this period (for example, for renovation or modernisation).

Standard rent increase in a German tenancy agreement

If your contract is neither a Staffel (tiered rent) nor an Index (index-linked) contract, then the rent increase rule (Mieterhöhung) applies — no more than 20% over a period of 3 years and no sooner than 12 months after the last price increase. A justification for the price increase is required (rent index, Expert report, comparable properties). Otherwise, the demand is invalid and a Rückzahlung (refund of the overpaid amount) + fine applies. The tenant has approximately 3 months (the remainder of the current month and two full months) to check the validity of the price increase, contact the Mietverein or a lawyer, and ultimately either give written consent or object in writing (Section 558b(2) of the Civil Code (BGB)If there is no response from the landlord within 3 months, the price increase comes into effect on the basis of “tacit consent”.

If the tenant has not agreed to the price increase, it does not take effect automatically. The landlord can file a claim in court for forced consent. Until the court's decision, the old rental rate is paid.

If the landlord has not justified the rent increase and has not submitted the justification in writing, such an increase is considered void in court. If there was an overpayment, they will be ordered to refund it, and the landlord will pay the tenant's legal costs.

rent index This is an official summary table of housing costs in a specific city. Based on the square footage, year of construction, location and other factors, a reasonable (adequate) rent amount is determined. To find this index, enter “Mietspiegel” and the name of your city into a search engine.

Expert report — is an expert valuation of a property. The flat may not fit into the standard valuation and may not be reflected in the Mietspiegel (historic building, non-standard floor space). In that case, a Gutachten can be used to justify a rent increase in Germany. A certified property valuer is brought in to produce a report. This takes into account the condition and characteristics of the building, floor level, fixtures and fittings, actual transactions involving similar accommodation, year of construction, and so on.

comparable properties - comparison of three similar flats in the same area to justify a rent increase. The flats must be in the same district, have the same floor area, similar furnishings and be on comparable floors. The level of the rent increase is determined on this basis if it is not possible to use the two previous methods. The conclusion must state the current rent, the addresses of the flats, the floor, the year of construction, and the fixtures and fittings. If this data is not in the document, the tenant has the right to ignore the demand for an increase in the rent of the flat.

Increase in Nebenkosten utility charges

In addition to the rent, there are also monthly utility bills, known as Nebenkosten. These include charges for water supply, sewage, waste disposal, area cleaning, lighting of common areas, lift maintenance, caretaker services, gardening and snow removal, fire alarm systems, and building insurance. Heating, hot water, electricity, administrative expenses, capital repair costs, and building depreciation are not included here. Usually, Nebenkosten are distributed proportionally based on the apartment size or the number of occupants.

An invoice for these payments is issued monthly as an advance payment. Once a year, actual expenses are calculated and the difference is paid or refunded. The annual statement arrives 12 to 18 months later, but no later than 31 December of the following year. The statement must reflect your expenses in detail and you have 12 months after receiving the bill to request copies of primary documents and to dispute inflated or unjustified items. (Section 556(3) of the Civil Code)

Sometimes it is rather difficult to understand the extra charge statement sent to you, because it contains many small items, the calculation is done retrospectively, and there is no limit on price increases when service providers raise their prices. Therefore, it is always worth keeping the primary documents, taking time to understand the data, comparing the square footage with neighbours, and seeking advice from a Mietverein or under legal expenses insurance.

In what cases can the tenant reduce the rent

Right to a rent reduction

German law rent reduction states that the tenant has the right to a partial or total rent reduction in the event of substantial defects:

There is a major defect in the apartment upon check-in or discovered during the tenancy that restricts its use under the agreement. In this case, the rent is not payable at all from the date this defect is discovered until the moment it is remedied (flooding, collapsed staircase, heating not working in winter).
If the problem reduces the standard of comfort but it is still possible to live there, the tenant is entitled to pay a rent reduced in proportion (by 10-50%). For example: the hot water supply is periodically cut off, the lift breaks down frequently, the actual floor area is 10% smaller than stated, or the flat has defects such as mould or damp.

However, the landlord also has the right to remedy the defects themselves first.

However, you won't manage to reduce the rent in the event of dim lighting, a tiny crack in the tile, or a speck of paint.

How to pay less rent in Germany - a step-by-step guide:

Termination of a tenancy agreement and unlawful eviction in Germany

When we talk about eviction, we mean the forced vacation of housing in cases where the tenant fails to fulfil their contractual obligations. This is a legal procedure that requires certain steps to be followed.

This is a fundamentally different process from the usual termination of a lease agreement (Termination).

Termination — is a contractual step when one of the parties declares its wish to terminate the tenancy relationship: the tenant can do this without stating a reason, observing a three-month notice period, and the landlord only if there is a «legitimate interest» (for example, bona fide Eigenbedarf). The contract formally ends upon the expiry of the set period, and, if the tenant voluntarily vacates the flat, no further court intervention is required.

Rules for standard termination of a tenancy agreement

Section 573 Ordinary termination by the landlord (Civil Code) - standard termination of the lease agreement by the landlord.

The tenant may terminate an indefinite-term contract without giving a reason by sending a notice in three months until the desired departure date (§ 573c I 1 BGB).

The landlord must observe longer notice periods, which depend on the duration of the tenancy (§ 573c I 2 BGB):

up to 5 years of residency — 3 months;
over 5, but not more than 8 years — 6 months;
over 8 years – 9 months.

Grounds and periods for termination of a lease

Under the Civil Code, the landlord may only serve a notice of termination if they have a justified interest in ending the tenancy agreement. Termination for the purpose of increasing the rent is excluded.

the flat is required by the owner or their close relatives (parents, children, spouse, grandchildren)
continued tenancy prevents the disposition of the house and obtaining economic benefit (the house is scheduled for demolition and a new one is planned to be built, or the house is subject to reconstruction, which is impossible while tenants are living there)
the accommodation is half of the landlord's house, and the landlord wants to combine the two parts and live in them himself
recurring complaints about noise or late rent payments
The property use is subject to change (it is being converted from residential to commercial)

Step-by-step procedure for legal eviction from an apartment in Germany:

Notice of termination of the tenancy agreement
Before the landlord can proceed with an eviction, they must first notify the tenant in writing: «The contract is terminated. You must move out by such and such a date.» The notice must state the reasons for termination, the period of time within which the tenant can remedy the defects/reasons that led to the termination of the contract, or move out. In the case of rent arrears, there is sometimes first a brief «reminder-demand» (Mahnung) asking for the debt to be settled.

Summary dismissal (immediate termination) is governed by Section 543 BGB. This means that the termination of the lease agreement takes effect immediately upon receipt of the written notice.

The reasons for urgent eviction may include (after a written warning and upon repeated occurrences):
• non-payment of rent or frequent delays of more than 2 months;
• breach of the peace;
• breach of tenancy agreement;
• accommodating more people than specified in the tenancy agreement;
• subleasing without the landlord's permission;
• use of the flat for other than its intended purpose;
• causing damage to property;
• causing a nuisance to neighbours.
Claim for eviction
If the deadline from the letter has passed and the tenant has not vacated the rented property or remedied the reasons that led to the eviction, the landlord submits an application to the district court. Depending on the workload of the court, this can last from six months to two years. The parties present their evidence. If the court rules in favour of the landlord, the tenant will receive an eviction notice.

Payment of legal costs
The court calculates the fee, which depends on the annual rent amount:
• if the warm rent is €400 a month;
• the disputed amount is calculated as 12 months × €400 = €4,800;
• The state fee comes out to roughly €438.

These monies are paid first by the claimant (landlord), and can then be recovered from the tenant through the courts.

Court bailiff
When the court issues a judgement to «vacate the property», the owner invites bailiffs. They set a date, arrive, open the door (with a carpenter and locksmith if necessary), draw up an inventory of belongings and remove the property. Only after this is the flat legally vacant.

Very important: The landlord is not entitled to change the locks or remove items himself.

Breaching the rules may result in a fine or criminal proceedings for arbitrary action, as eviction is only possible by court order. Otherwise, the landlord is in breach of criminal law under the offence of «arbitrary action» (Section 858 of the BGB).

During eviction, the specific date is determined by the court and bailiff, taking into account possible stays of execution, but without a court decision, forced eviction is impossible in principle.

Illegal eviction from a flat

Illegal actions of the landlord during eviction are:

Changing locks without a court order
Disconnection of water and electricity
Threats
Moving things out of the flat
Failure to comply with the termination notice periods specified in the lease agreement
Eviction of tenants without a court order
And other obstruction of actual use

Tenant rights against arbitrary action by the landlord (verbotene Eigenmacht) are protected by § Section 858 of the BGB.

How German legal expenses insurance with the housing and property law module (Wohn-Rechtsschutz) works

Legal expenses insurance with an add-on module Tenants' and residents' legal protection insurance It makes it just as easy to consult a solicitor on housing matters as it is to see your GP: if you spot a problem, simply call the helpline, and the insurer will cover the financial aspects of the dispute. Within the agreed limit, it covers not only the lawyer’s fees but also all associated costs — court fees, the services of valuation experts, technical assessments (for example, regarding heat meters), and, if the parties so wish, mediation. Thanks to this, even a major dispute does not become a burden costing thousands on the tenant’s budget.

In practice, the policy is especially useful when:

the landlord increases the rent without proper justification or disregards the 20 % limit over a period of three 3 years;
suspicious items are appearing in the annual Nebenkosten bill, and a professional audit of all primary documents is required;
the landlord is sending a termination notice citing «personal use», and we need to make sure the reason isn't fictitious;
in the case of serious housing defects (damp, mould, lack of heating), it is necessary to legally and correctly reduce the rent;
A dispute arose regarding the deposit, repairs or the dates of the conference.

The key advantage of the insurance is that it removes the fear of potential lawyer and court bills, ensuring access to qualified representation and thereby levelling the playing field in negotiations with the landlord.

Examples of court decisions where legal expenses insurance paid the costs

Real-life examples of when legal expenses insurance helped with an unlawful rent increase and illegal eviction:

Cancellation of unauthorised eviction

The Local Court of Berlin-Schöneberg (Amtsgericht Berlin-Schöneberg), in a ruling dated 14 August 2019 (case no. 6 C 276/18), ordered the landlord to pay over €20,000 for unlawful eviction (even if there is a reason for termination of the agreement, it is impossible to do so without a court order. A court judgment is required).

The landlord arbitrarily, without a court order, vacated the flat and threw away the tenant's belongings. The court awarded the tenant compensation for both material damage and non-material damage, as the landlord's actions violated the tenant's general right of personality (Allgemeines Persönlichkeitsrecht).

Unlawful price hike

The clause regarding the index-linked price change was «hidden» in the contract under «Miscellaneous Agreements» as the fourth item. The court ruled that the payment amount was not specified «transparently» and declared this contract clause invalid. The overpayment was returned to the tenant.

Fake personal needs

The landlord cited «personal need» to evict the tenant. However, cousins do not fall into the category of «close relatives». In case VIII ZR 276/23, GbR-owner-cousins wanted to move one of them in, but the court declared such termination invalid. Only parents, children, and spouses qualify for early termination of a tenancy agreement.

To summarise, it is important to note that German tenancy law establishes strictly regulated mechanisms: a landlord may only increase the rent if pre-defined conditions (Index- or Staffelmiete) or the limit «20% over three years» in the case of a standard increase, whilst eviction is permitted only by court order and through the actions of bailiffs. Tenants, in turn, benefit from the safeguards provided by law — a period to verify the justification for a rent increase, the opportunity to object, and the right to a rent reduction in the event of serious defects in the property. Practice shows that strict adherence to these procedures and taking out legal expenses insurance in good time, including a ‘Miet- / Wohnrechtsschutz’ cover, significantly reduce financial risks and ensure predictability in the fulfilment of contractual obligations.
