What Is the 2026 German Tenancy Law Reform?
German tenancy law is entering a period of significant change. The federal government has announced a reform package that will affect how rent is calculated, how contracts are signed, and what obligations landlords must meet. While the core framework remains the Bürgerliches Gesetzbuch (BGB), the 2026 updates target three main areas: stricter rent control, digital contract options, and clearer rules for energy-related modernisation.
The reforms respond to housing shortages in major cities. Berlin, Munich, Hamburg, and Cologne have seen rents rise faster than incomes. The government wants to slow these increases while giving landlords more certainty about cost recovery. Anmeldung Guide
For expats, the most important changes affect rental applications, deposit handling, and termination protection. Some provisions are already in force, while others will roll out through 2025 and 2026. Always verify current rules at bundesregierung.de before signing a contract.
How the Mietpreisbremse (Rent Brake) Limits Your Rent
The Mietpreisbremse is the most visible part of German tenancy law for new renters. It applies in cities that have declared “tight housing markets” (angespannte Wohnungsmärkte). In these areas, landlords cannot charge more than 10% above the local reference rent (ortsübliche Vergleichsmiete).
To check if your apartment qualifies, request the Mietspiegel (rent index) from your local housing office (Wohnungsamt). The index shows average rents by district, size, and building age. Exceptions exist for buildings first occupied after October 2014 and for apartments renovated with costs exceeding €30,000 per unit. Social housing (Sozialer Wohnungsbau) is also exempt from the rent brake.
If you suspect your rent is too high, you have six months from moving in to challenge it. Landlords who violate the rent brake face fines up to €50,000. However, enforcement varies by city, and many tenants never check. Rental Deposit Rules
Rent Increase Rules: The 15% Cap and Local Reference Rents
German tenancy law limits how much landlords can raise rent on existing tenancies. Once your rent reaches the local reference level, increases are capped at 15% within any three-year period. This prevents sudden spikes and gives you budget stability.
Your landlord must request increases in writing (Mietserhöhung) and provide the calculation basis. You have three months to accept or reject. If you reject, the landlord can sue, but courts rarely side with landlords who ignore the 15% cap. Index-linked rent (Indexmiete) is an exception—this adjusts automatically based on inflation, but only if your contract explicitly includes it.
Utility costs (Nebenkosten) can also increase if actual consumption rises. However, landlords must provide an annual statement (Nebenkostenabrechnung) within 12 months of the billing year ending. Disputes over heating and hot water costs are common. Check your contract for which utilities are included in the Kaltmiete (cold rent) versus the Vorauszahlung (advance payment).
| Type of Increase | Maximum Amount | Notice Period | Requirements |
|---|---|---|---|
| To local reference rent | 10% above Mietspiegel | 3 months | Written request with calculation |
| Modernisation surcharge | 3% per year | 3 months | Detailed cost breakdown |
| Index rent (Indexmiete) | Based on inflation rate | 1 month | Contract must specify formula |
| Utility cost adjustment | Actual costs | 12 months | Annual statement required |
Termination Protection: When Can Your Landlord End the Tenancy?
German tenancy law strongly protects tenants from arbitrary eviction. A landlord can only terminate a contract for specific reasons: serious rent arrears (usually two months’ rent), personal use (Eigenbedarf), or significant breach of contract. Notice periods start at three months but extend by five years for every five years of tenancy.
Personal use terminations are restricted in cities with tight housing markets. Berlin has banned Eigenbedarf in certain districts until 2028. Other cities like Munich and Hamburg have similar restrictions. Always check local regulations before assuming your landlord can evict you for personal use.
If you receive a termination notice, respond in writing within two months. Ignoring it can lead to eviction proceedings. Tenants with disabilities, pregnant women, or families with young children receive additional protection and cannot be terminated without court approval. Schufa Credit Check
Modernisation Surcharges: When Landlords Pass Costs to You
Landlords can pass 8% of modernisation costs to tenants as a rent increase. For a €50,000 renovation, that means a €4,000 annual surcharge, or roughly €333 per month. However, the increase cannot exceed 3% of the current rent per year. This limits how quickly landlords can recover costs.
You must receive three months’ written notice before the increase takes effect. The notice must detail the work, costs, and calculation method. You can refuse the increase if the work is not a genuine modernisation but routine maintenance. Energy-efficient upgrades (energetische Modernisierung) receive special treatment. Landlords can pass 8% of costs even if the building is not in a tight housing market.
However, landlords cannot combine modernisation surcharges with other rent increases in the same year. If your rent is already at the local reference level, the modernisation increase must wait until the next calendar year. This prevents “double dipping” and protects tenants from sudden cost spikes.
Your Deposit: The 3-Month Rule and Getting It Back
Your security deposit (Kaution) cannot exceed three months’ cold rent (Kaltmiete). This includes base rent but excludes utilities. Landlords must hold the deposit in a separate account and inform you of the account details. They cannot mix your deposit with their operating funds.
Interest earned on your deposit belongs to you. When you move out, the landlord must return the deposit within six months, provided the apartment is in good condition. Deductions for damages must be itemized and reasonable. Normal wear and tear (Abnutzung) cannot be charged to you.
If your landlord delays or refuses to return your deposit, send a formal letter (Abmahnung) giving them 14 days to comply. If they still refuse, you can sue in small claims court (Amtsgericht). Tenant associations often help with these disputes. Keep photos of the apartment’s condition when you move in and out.
Special Considerations for Expats and Non-EU Citizens
German tenancy law applies equally to EU and non-EU citizens. Landlords cannot reject you based on nationality. However, they can require proof of income and creditworthiness, which creates practical barriers for newcomers. Without a German credit history, you may need to provide three months’ bank statements, an employment contract, or a guarantor (Bürge).
Some landlords accept a higher deposit (up to the legal maximum) instead of a guarantor. Non-EU citizens should ensure their residence permit (Aufenthaltstitel) is valid for at least 12 months. Short-term visas may make landlords hesitant. Check make-it-in-germany.com for country-specific guidance on documentation.
Registration (Anmeldung) is mandatory within 14 days of moving in. You need this for your rental contract, bank account, and visa renewals. Some landlords require proof of registration before handing over keys. Delays in registration can complicate your rental application.
How to Prepare a Winning Rental Application in 2026
Competition for apartments remains fierce in major cities. Landlords can choose tenants freely, so your application must stand out. Prepare a Mieter_selbstauskunft (tenant self-disclosure) with your personal details, income, and rental history. This document is standard in Germany and shows you understand local practices.
You will need a Schufa credit report, recent payslips, and a Mietschuldenfreiheitsbescheinigung (rental debt clearance certificate) from your previous landlord. Non-EU citizens should include a copy of their residence permit and a letter from their employer confirming job security. Digital applications are becoming more common. Some platforms verify documents automatically.
In-person viewings still matter. Arrive on time, dress neatly, and bring printed copies of all documents. Never pay an application fee—this is illegal in Germany. If you are rejected, you are not entitled to know why. Focus on strengthening your next application.
What Landlords Must Do Differently Under the New Rules
Landlords face stricter documentation requirements. They must provide an energy performance certificate (Energieausweis) before signing a contract. Digital contracts are now legally valid, but landlords must still provide a physical copy if requested. This dual requirement ensures tenants can review terms on paper.
Maintenance obligations remain unchanged. Landlords must keep the apartment in livable condition, including heating, plumbing, and structural integrity. They cannot delegate maintenance costs to tenants through contract clauses. Rent increases require more transparency. Landlords must reference the official Mietspiegel and justify any increase above inflation.
Failure to comply can result in fines and rent repayment orders. For non-EU landlords, tax rules also apply—consult the Bundesfinanzministerium for guidance. Landlords must also register rental income and may face audits if they underreport.
Where to Get Help and Verify Current Rules
Tenant associations (Mietervereine) offer legal advice and representation for €50–200 per year. They review contracts, handle disputes, and represent you in court. The largest is the Deutscher Mieterbund, with offices nationwide. Many cities have local branches that understand regional market conditions.
Official information is available at gesetze-im-internet.de for legal texts and bamf.de for immigration-related queries. For EU citizens, europa.eu provides cross-border tenant rights information. These sources are updated regularly and provide the most current legal text.
Rules and fees change; confirm with the responsible office before you act. City-specific regulations, especially in Berlin, Munich, and Hamburg, may differ from federal law. Always verify with your local Bürgeramt or tenant association before signing or terminating a contract.
Frequently Asked Questions
Can my landlord increase the rent if I just moved in?
Yes, but only under strict conditions. The rent cannot exceed 10% above the local reference rent in tight housing markets. Even if you agreed to a higher rent initially, you can challenge it within six months of moving in. Send a written objection and request the Mietspiegel calculation.
Do I need a German bank account to rent?
No, but it helps. Landlords prefer accounts that allow automatic rent withdrawals (Lastschrift). International transfers are possible but may incur fees and delays. Open a German account as soon as you arrive to simplify payments and build your financial history.
What if my landlord doesn’t return my deposit?
Send a formal written request with a 14-day deadline. If they still refuse, contact your local tenant association or file a claim at the Amtsgericht. Keep all communication in writing and document the apartment’s condition with photos. Small claims court is designed for these disputes and does not require a lawyer.
Are there different rules for furnished apartments?
Furnished apartments (möblierte Wohnungen) are exempt from the rent brake. They are typically short-term contracts (1–12 months) and can be terminated with two weeks’ notice. Use these only as temporary solutions while you search for permanent housing. The deposit rules still apply.
How do I check if my rent is legal?
Request the Mietspiegel from your city’s housing office (Wohnungsamt). Compare your rent to the reference value for your apartment’s size and location. If you exceed the 10% threshold, consult a tenant association about reducing it. You can also use online tools provided by your city, but verify official sources.
