What to expect in this guide
Germany is a country of tenants: More than half of all households live in rented accommodation. And German tenancy law offers tenants some of the strongest protection in the world. The problem: Very few tenants know their rights well enough to actually enforce them.
Too many sign contracts with invalid clauses. Too many pay utility bills without questioning them. Too many accept rent increases that would be legally challengeable. And too many spend money during the handover of the apartment that they don't actually owe.
This guide accompanies you through the entire tenancy – from the prospective tenant's self-disclosure (Mieterselbstauskunft) before moving in to the deposit refund after moving out. Each section refers to an in-depth article for your specific situation.
The Foundation: What does tenancy law regulate?
Tenancy law is primarily regulated in the German Civil Code (Bürgerliches Gesetzbuch - BGB, Sections 535–580a). It establishes the mutual fundamental duties: The landlord owes you an apartment in a contractual condition (§ 535 Para. 1 BGB), and you owe them the rent and careful treatment of the apartment.
Crucial for tenants: Many BGB regulations are mandatory in favor of the tenant. This means that a tenancy agreement that falls short of these minimum rights is automatically invalid on that point – even if you have signed it. Your signature on a contract does not make a legally invalid clause legally effective.
Phase 1: Before Moving In
What the landlord may and may not ask in the prospective tenant's self-disclosure (Mieterselbstauskunft)
Before concluding a contract, many landlords request a prospective tenant's self-disclosure (Mieterselbstauskunft). This is a questionnaire about personal and financial circumstances. This sounds harmless – but it is legally severely restricted.
Questions about income, occupation, and a Schufa credit report are permissible. Questions about family planning, religious affiliation, political conviction, or an existing severe disability are not. You are allowed to lie to inadmissible questions without this having later consequences for your tenancy agreement – because the question itself was illegal.

Reviewing the tenancy agreement before signing
Before you sign, you should carefully read your tenancy agreement – ideally with legal support. Many standard contracts contain clauses that are either legally invalid or entail significant financial risks. Particularly often problematic: clauses on cosmetic repairs (Schönheitsreparaturen), minor repairs (Kleinreparaturen), pet prohibitions, and regulations on subletting.
Phase 2: The Ongoing Tenancy Agreement
Invalid clauses: What your landlord cannot demand
Cosmetic Repairs (Schönheitsreparaturen)
One of the most common points of contention in German tenancy law: Who has to renovate the apartment when moving out? In principle, the renovation obligation lies with the landlord (§ 535 BGB). Many tenancy agreements transfer this obligation to the tenant through clauses. This is permissible under certain conditions – but only if the clause is formulated very precisely.
The Federal Court of Justice (Bundesgerichtshof - BGH) has clarified in a series of judgments: Clauses with rigid deadlines (e.g., "paint every three years"), final renovation clauses without considering the degree of wear and tear, or pro-rata settlement clauses (Quotenabgeltungsklauseln) are invalid. In practice, most cosmetic repair clauses in tenancy agreements are flawed – and therefore void.

Pets
Many tenancy agreements contain clauses such as "pet keeping is not permitted" or "requires the landlord's permission". General prohibitions of any pet keeping – including for small animals like hamsters or ornamental fish – are, according to consistent BGH case law, invalid. For dogs and cats: A blanket prohibition in the contract only offers limited protection to the landlord; they must demonstrate objective reasons in individual cases.

Subletting
Anyone who wants to go abroad for a while, enter into a partnership, or sublet a room for financial reasons generally needs the landlord's permission. However, according to § 553 BGB, the tenant has a right to obtain this permission if there is a legitimate interest. If the landlord refuses permission without a valid reason, the tenant even has a special right of termination.

Utility Costs (Nebenkosten): Your money is in the bill
Utility bills (Betriebskostenabrechnungen) are among the most common sources of error in tenancy relationships. Estimates by tenants' associations suggest that every second utility bill contains errors – to the detriment of the tenant.
What can be charged?
The basis is the German Ordinance on Operating Costs (Betriebskostenverordnung - BetrKV). It exhaustively lists which costs the landlord may pass on to the tenant. Anything not listed in this ordinance may not be charged – even if it is stated in the tenancy agreement. Commonly unlawfully charged: administrative costs, repair costs, and maintenance expenses.
→ Checking utility bills: The most common landlord errors
The billing period
The landlord has an exclusion period of twelve months after the end of the billing period for the utility bill (§ 556 Para. 3 BGB). If the bill is submitted too late, they lose their claim for additional payment. This deadline is ignored by many landlords – and not enforced by even more tenants.

Rent Increase: When is it permissible – and when not?
Rent increases are not arbitrary. The BGB provides strict formal and substantive requirements.
Rent increase up to the local comparative rent (Vergleichsmiete)
According to § 558 BGB, the landlord may increase the rent to the local comparative rent – but only if the rent has remained unchanged for at least 15 months, the increase request is justified in writing (e.g., by a rent index (Mietspiegel), expert opinion, or comparable apartments), and the capping limit (Kappungsgrenze) is observed: Within three years, the rent may increase by a maximum of 20 percent (in tense housing markets, even only 15 percent).

Rent increase after modernization
Special case: modernization surcharge (Modernisierungsumlage): After a modernization measure, the landlord may pass on eight percent of the incurred costs annually to the rent (§ 559 BGB). This sounds manageable, but in practice, it can mean a significant rent increase. It is crucial that only actual modernization costs may be passed on – not maintenance costs that the landlord would have to bear anyway.

Phase 3: When something is wrong with the apartment
Defects and rent reduction (Mietminderung): Your strongest tool
If the leased property is defective, you have the right to rent reduction (Mietminderung) (§ 536 BGB). The law provides that the rent is reduced to an appropriate level for the duration of the defect. Appropriate means: proportional to the actual impairment of the living quality.
Important: You must notify the landlord in writing of the defect before you reduce the rent. Anyone who simply pays less without having reported the defect risks termination due to payment arrears.
Mould in the apartment
Mould is one of the most common and consequential apartment defects. Depending on its extent, it justifies a rent reduction of 10 to 100 percent of the gross rent. Landlords often try to attribute the cause to the tenant (incorrect ventilation). Whether this is justified depends on structural factors and the specific cause – and is often disputed.

Heating failure in winter
A defective heating system in winter is a significant defect. If the landlord does not react to your defect notification within a reasonable period, you can, in addition to the rent reduction, also claim a substitute performance (Ersatzvornahme) – i.e., arrange for the remedy yourself at the landlord's expense.

Phase 4: Termination – whether you want to or not
When the landlord terminates
Landlords may only terminate tenants for legally recognized reasons (§ 573 BGB). Arbitrary terminations do not exist in German residential tenancy law.
Termination due to owner-occupancy (Eigenbedarf)
The most common form of landlord termination: The landlord or a close relative wishes to move into the apartment themselves. Owner-occupancy terminations are legally recognized but are often used abusively. Prerequisites: The owner-occupancy must be concrete and serious, announced in a timely and formal manner, and actually occur. Faked owner-occupancy can trigger damage compensation obligations on the part of the landlord.

Extraordinary termination without notice by the landlord
Extraordinary termination without notice is only permissible for an important reason (§ 543 BGB). The most common reason in practice: rent arrears of more than two months' rent. Significant disturbances of the domestic peace or unauthorized subletting can also justify termination without notice – but the formal requirements are high, and many terminations without notice are flawed.

If you want to terminate yourself
As a tenant of an unlimited-term apartment, you have the right to ordinary termination with a notice period of three months to the end of the month (§ 573c BGB). The termination must be in writing and signed by hand. Common mistakes: calculating incorrect deadlines, terminating only by email, or forgetting that in shared flats (WGs), all co-tenants must sign.

Phase 5: Moving Out
Moving out is the moment when many tenants unnecessarily lose money – through handover protocols (Wohnungsübergabeprotokolle) that disadvantage them and through deposit deductions (Kautionsabzüge) that are not legally defensible.
The apartment handover protocol (Wohnungsübergabeprotokoll)
During the key handover, the landlord usually prepares a handover protocol, in which defects or damages are recorded. This document can be decisive in later disputes about the deposit.
Do not sign anything that is not true. The protocol is a contract. What you sign, you can hardly dispute later. Insist on a complete inspection, sufficient time for review, and on taking your own photos.

The security deposit (Mietkaution)
The landlord may demand a maximum of three months' net cold rent (netto kalt) as a security deposit (§ 551 BGB). After moving out, they must repay the deposit within a reasonable period – case law generally accepts up to six months. After that, you can legally claim the repayment.
Important: Deductions for normal wear and tear are inadmissible. Damages arising from the ordinary use of the apartment are at the landlord's expense. They may only deduct actual damages from the deposit.

Frequently Asked Questions (FAQ)
Can I dispute a tenancy agreement after I have signed it?
Yes – but not arbitrarily. You can challenge individual clauses that violate legal requirements. Such a clause is automatically void without the need for an appeal (§ 134 or § 307 BGB). You can only challenge the entire contract if it came about through fraudulent misrepresentation or threat (§ 123 BGB).
When may I reduce the rent?
As soon as the apartment has a defect that cancels or significantly reduces its suitability for contractual use (§ 536 BGB). Prerequisite: You must have notified the landlord of the defect in writing and given them a reasonable deadline to remedy it. The reduction applies from the time the defect was reported.
Do I, as a tenant, have to paint the apartment when moving out?
Only if your tenancy agreement contains an effective cosmetic repair clause (wirksame Schönheitsreparaturklausel). Most standard formulations in circulation are, according to BGH case law, invalid. If the clause is invalid, the landlord bears the renovation obligation. Normal signs of wear and tear are in any case not a basis for costs.
How long does the landlord have to repay the security deposit?
There is no fixed legal deadline, but case law grants the landlord a review and billing period of a maximum of three to six months. After that, they are in default, and you can demand interest and take legal action.
Can the landlord simply evict me?
No. For every termination of a residential tenancy, the landlord needs a legitimate interest (§ 573 BGB). Owner-occupancy, significant breach of duty by the tenant, or hindering economic exploitation are the legally recognized reasons. A termination without cause is invalid – even if it is in writing and on time.
What applies if I receive an owner-occupancy termination (Eigenbedarfskündigung)?
First, check the formal requirements: The termination must be in writing, specify the concrete owner-occupancy, and comply with the statutory notice periods (three to nine months depending on the duration of the tenancy, § 573c BGB). Then, substantively check whether the owner-occupancy is plausible and serious. Under certain circumstances, you can object to the termination (§ 574 BGB), for example, in cases of undue hardship due to old age, illness, or lack of alternative housing.
