A rental contract defines which apartment you are renting, how much you pay, and under what conditions you can move out. Under § 535 BGB, the landlord must provide the dwelling and maintain it in a condition suitable for agreed use, while the tenant must pay rent. Before signing, it is worth checking not only the monthly total, but also any annexes, rent increase mechanisms, repair obligations, and restrictions on termination.
The overview below covers a standard apartment lease for permanent residential living. Statutory exceptions apply to temporary housing, certain furnished rooms in the landlord’s own residence, and student dormitories (§ 549 BGB). The mere presence of furniture does not automatically mean that standard tenant protections are excluded.
- Term: Check the lease start date, legal ground for any fixed term, and the earliest possible termination date. An open-ended contract may also restrict ordinary termination. → Parties and Term
- Money: Distinguish basic rent from operating costs and verify whether heating is included. The deposit is capped at three months’ rent excluding operating costs; a cash deposit can be paid in three installments. → Rent and Deposit
- Repairs: Standard clauses requiring cosmetic repairs are void if the apartment was handed over unrenovated without adequate compensation. Minor repair clauses require both a single-repair cap and an annual ceiling. → Repairs
- Living Conditions: Read the agreed house rules; specific conditions apply to dogs, cats, and subletting part of the home to another person. → Rules of Residence
- Moving Out: Ordinary termination depends on the date the notice is received and compliance with the statutory written form. A simple text message or email is not sufficient. → Termination
- Handover: Record the condition of the dwelling, accessible utility meter readings, and the number of keys. A handover protocol is helpful, though there is no general legal obligation to compile one. → Apartment Handover
1. Parties, Apartment, and Lease Term
Who Is Renting and What Is Included
Verify the names and contact details of all parties. Check the address and description of the apartment, the specified floor area, the lease commencement date, and the list of included property. If the arrangement includes a cellar, parking space, or fitted kitchen, ensure this is explicitly reflected in the documentation. Comparing the handover scope with prior understandings is strongly advised (Verbraucherzentrale).
If multiple tenants sign the contract, each can be held liable for the entire debt. Joint contractual obligations are governed by default joint and several liability (gesamtschuldnerische Haftung, § 421 and § 427 BGB). As explained by the Deutscher Mieterbund, joint tenants must terminate the lease jointly; one partner simply moving out does not terminate their contractual liabilities. Entering both partners as tenants is therefore a decision with legal consequences for both.
A written lease helps document agreements, but not every rental becomes valid only upon signature. For leases with a term exceeding one year, § 550 BGB provides a distinct statutory consequence for non-compliance with written form: such an agreement is deemed open-ended, and ordinary termination cannot take effect earlier than one year after handover.
Open-Ended and Fixed-Term Leases
An open-ended lease (unbefristeter Mietvertrag) has no preset expiration date. However, this does not rule out an agreed restriction on ordinary notice.
For a standard fixed-term residential lease (Zeitmietvertrag), § 575 BGB permits only three categories of statutory grounds. Upon expiry of the term, the landlord intends to:
- Use the premises for themselves, family members, or members of their household (Eigenbedarf).
- Lawfully demolish, substantially alter, or renovate the premises, where continuation of the lease would significantly hinder such work.
- Provide the dwelling to an individual obliged to perform designated official service duties.
The specific statutory ground must be communicated in writing upon entering into the contract. It may be contained in the lease itself or in a separate written notice. If the requirements of § 575 are not met, the tenancy within the scope of this provision is deemed open-ended. A mere notation of “for two years” without proper statutory grounds is invalid.
When You Can Move Out for the First Time
Look specifically for any clause specifying an exclusion of ordinary termination (Kündigungsausschluss). As explained by the Mieterbund, for standard terms the maximum permissible duration is four years from the date the contract is signed until the first possible termination date, including the notice period. This is not a universal cap for every individually negotiated agreement, nor does it bar all avenues of terminating a tenancy.
Before signing, identify the earliest date when the lease could terminate upon your standard notice. Review this date together with the required notice period rather than relying solely on the number of years stated in the restriction clause. For stepped rent agreements, the special rule under § 557a Abs. 3 BGB also applies.
2. Rent and Deposit
Breakdown of Monthly Payments
| Payment | Meaning | What to Check |
|---|---|---|
| Basic Net Rent (Nettokaltmiete, Kaltmiete) | Charge for apartment use excluding operating costs | Amount, start date, and increase mechanisms |
| Operating Costs (Betriebskosten, often Nebenkosten) | Agreed ongoing property running costs and municipal services | List of items; prepayments vs. lump sum; whether heating is included |
| Total Gross Rent (Warmmiete) | Basic rent combined with included operating expenses | Which services are already covered and which are billed separately |
| Security Deposit (Mietkaution) | Security for contractual obligations, separate from monthly rent | Amount, format of security, payment schedule, and escrow handling |
Do not count heating twice: it may already be included in the stated Nebenkosten figure. Electricity and internet are usually contracted separately, though the precise arrangement depends on the contract. With electric heating, costs may be billed via a separate domestic electricity account (Verbraucherzentrale NRW). For personal budgeting, combine the landlord payment with the services that must be paid independently.
Advance Prepayments and Lump Sums Are Different Conditions
Transferring operating expenses to the tenant must be explicitly agreed. The Operating Costs Ordinance (BetrKV) lists allowable expenses, such as water supply, heating, cleaning, and common-area lighting. Property management, general maintenance, and repairs do not qualify as Betriebskosten (§ 1 BetrKV).
Under § 556 BGB, a contract may specify:
- Advance Prepayments (Vorauszahlungen): settled annually, resulting in an additional payment or refund. The annual statement must be served no later than twelve months after the end of the settlement period. After this deadline, retroactive additional landlord claims are generally precluded, unless the landlord was not at fault for the delay.
- Lump Sums (Pauschale): cannot automatically be treated as prepayments subject to an annual statement.
Objections to an operating cost statement must generally be raised within twelve months of receipt; statutory exceptions apply if the tenant was not responsible for missing the deadline. Tenants may request inspection of supporting vouchers. Adjustments to operating charges are governed separately: for instance, prepayments may be adjusted to an appropriate level following an annual statement, whereas increasing a flat Pauschale requires statutory preconditions, including a corresponding contractual clause (§ 560 BGB).
Security Deposit
Under § 551 BGB, the initial security deposit must not exceed three months’ basic net rent excluding operating costs. If a monetary deposit is agreed, the tenant is entitled to pay it in three equal monthly installments: the first upon commencement of the tenancy, and the remaining two alongside the subsequent two monthly rent payments.
The landlord must hold a cash deposit separate from their personal assets (Insolvenzsicherheit). Accrued interest belongs to the tenant and increases the security. For student and youth housing, the statute provides an exception to the interest obligation.
How Basic Rent Can Increase
Check whether the agreement specifies stepped or indexed rent. These mechanisms differ from standard increases up to the local comparative rent.
| Mechanism | Key Conditions | What to Watch For |
|---|---|---|
| Up to Local Comparative Rent | Basic rent must remain unchanged for at least 15 months at the time the increase takes effect; a claim cannot be made earlier than one year after the last increase | Along with the comparative rent, a statutory cap (Kappungsgrenze) applies over three years: normally 20%, reduced to 15% in designated tight-market areas. Increases for modernization and operating costs are accounted for separately (§ 558 BGB) |
| Stepped Rent (Staffelmiete) | A written agreement sets future rent amounts or increases in euros in advance; each step must last at least one year | During stepped periods, increases under §§ 558–559b are excluded, though operating costs under § 560 may adjust. Calculate the exact payment for each scheduled milestone (§ 557a BGB) |
| Indexed Rent (Indexmiete) | A written agreement ties rent to the Consumer Price Index published by the Federal Statistical Office | Rent changes must be declared in text form detailing the index shift and calculated sum. The adjusted rent takes effect from the start of the second month following receipt; comparative rent increases are excluded (§ 557b BGB) |
Under an indexed lease, rent generally remains unchanged for at least one year; the law specifically permits adjustments to operating costs and certain modernization charges. An index increase can raise the rent, while an index decrease provides grounds for a rent reduction. This clause should not be mistaken for a fixed, predetermined expenditure schedule.
For increases under § 558, the municipal rent index (Mietspiegel) is a common method of justification. § 558a BGB also permits rent databases, expert surveyor appraisals, and references to three comparable apartments; existing qualified rent indices (qualifizierter Mietspiegel) carry additional formal requirements.
Rent control on new leases (Mietpreisbremse) is a distinct regulation. It applies in municipalities designated by state statutory decree: as a rule, the initial rent may not exceed the local comparative rent by more than 10% (§ 556d BGB). However, the statute incorporates exceptions for prior rent levels and recent modernizations (§ 556e), as well as exemptions for newly built apartments and first rentals following comprehensive modernization (§ 556f). For Staffelmiete, compliance is evaluated at each step; for Indexmiete, at the baseline rent. Contracts cannot simply be verified using an indiscriminate “local rent plus 10%” formula.
3. Cosmetic and Minor Repairs
Painting and Other Cosmetic Work
The general obligation to maintain the dwelling rests with the landlord, but contracts may delegate cosmetic repairs (Schönheitsreparaturen). Regarding standard form terms, the Federal Court of Justice (BGH) has ruled:
- Rigid time schedules that mandate repainting regardless of the actual condition of the property are invalid (associated in BGH jurisprudence with rulings including VIII ZR 361/03 and VIII ZR 21/13).
- Transferring cosmetic repairs to a tenant via standard terms is invalid if the apartment was handed over unrenovated or in need of renovation without adequate compensation (VIII ZR 185/14 and VIII ZR 242/13). Minor signs of prior wear do not automatically render an apartment unrenovated.
The source for these principles is an official BGH press release. This ruling does not provide blanket assurance that every tenant is exempt from all move-out painting: the move-in condition, contractual wording, and financial compensation are decisive.
Maintain detailed descriptions and photos of all wall and ceiling finishes. If compensation for the initial unrenovated condition was agreed, ensure it is documented in writing. This evidence establishes whether cosmetic repair clauses are enforceable. Normal wear and tear from agreed use does not constitute tenant damage (§ 538 BGB).
Minor Repairs
A minor repairs clause (Kleinreparaturklausel) may shift to the tenant the expense of minor fixes to fixtures subject to frequent direct physical use, such as water taps, light switches, and window handles.
According to guidance from Mieterverein Leipzig, valid clauses must include a cost cap for each individual repair and an annual cumulative expenditure limit. Check the exact figures, eligible fixtures, and remaining phrasing in the lease. The presence of two numbers does not alone establish the clause’s legal validity.
If a repair’s total cost exceeds the single-repair cap, the clause does not require the tenant to pay a partial contribution or “the first few euros” towards the bill. Commissioning tradespeople remains the responsibility of the landlord. Liability for culpable tenant damages is governed separately and must not be confused with cost allocation for standard minor repairs.
4. Rules of Residence
House Rules Annex
Request the house rules (Hausordnung) and review them thoroughly before signing. For standard terms to become part of the contract, the tenant must have had the opportunity to review them and agree to their inclusion (§ 305 BGB). The mere existence of a separate sheet does not render every provision automatically binding; standard clauses remain subject to judicial content review under § 307 BGB.
Confirm specific quiet hours, rules for common areas, basement storage, and building cleaning duties. Avoid assuming a single universal schedule across Germany: inspect the specific house rules and local municipal guidelines.
Pets
Small animals, such as ornamental fish or hamsters, may generally be kept without separate consent, provided keeping them causes no nuisance, property damage, or disruption to neighbors (Mieterbund NRW).
A blanket standard prohibition on all dogs and cats is invalid, but this does not grant unconditional permission to keep any animal. The Federal Court of Justice (BGH, VIII ZR 168/12) requires weighing the circumstances of each case alongside the interests of both parties and neighboring tenants. Prior to moving in with a pet, review lease terms and obtain written approval where required.
Subletting Part of the Apartment to Another Person
If a legitimate interest arises after signing the lease to transfer part of the dwelling to a third party, § 553 BGB grants the right to request permission for partial subletting (Untervermietung). This rule does not grant an automatic right to sublet the entire apartment.
Permission may be denied on statutory grounds, such as substantial reasons related to the prospective subtenant’s person, overcrowding, or undue hardship for the landlord. In certain circumstances, consent may be conditioned upon a reasonable rent adjustment. Tenants should first submit a formal written request describing their legitimate interest and proposed sublet terms.
5. Lease Termination
Tenant Notice
For ordinary termination of an open-ended residential lease, the calendar formula under § 573c Abs. 1 BGB applies: the notice of termination must reach the landlord no later than the third working day of a calendar month for the lease to end at the expiry of the second following month. This procedure is commonly referred to as a three-month notice period. Timely physical receipt by the landlord is decisive, not merely the mailing date.
Special notice rules apply to temporary rentals and certain furnished rooms. Furthermore, verify whether a waiver of ordinary termination is in place; standard termination rules for open-ended leases cannot automatically be applied to valid fixed-term agreements.
§ 568 BGB mandates strict statutory written form (Schriftform). The standard method is a signed paper notice. Under § 126 and § 126a BGB, statutory electronic form with a qualified electronic signature is also legally permissible. Plain emails, scanned signatures, SMS, or messenger messages do not satisfy this requirement; the consequences of formal defect are governed by § 125 BGB.
Where multiple tenants are party to the lease, notice must be issued jointly. Always secure verifiable proof of delivery showing when the recipient received the letter.
Landlord Notice
Under standard procedure, ordinary termination by the landlord requires a legitimate interest (berechtigtes Interesse, § 573 BGB). Statutory grounds include substantial culpable breach of contract by the tenant, personal use (Eigenbedarf) by the landlord or close family, or certain economic feasibility grounds. These reasons must be stated in the notice; the mere intent to re-let at a higher rent does not qualify.
The standard landlord notice period is three months, increasing to six months after five years and nine months after eight years measured from the date the apartment was handed over to the tenant (§ 573c BGB). Special statutory frameworks exist: for example, § 573a BGB permits termination without legitimate interest in an owner-occupied building with no more than two apartments, but extends the required notice period by an additional three months.
When the Standard Notice Period May Not Apply
Termination without notice (fristlose außerordentliche Kündigung) requires compelling cause and is governed by separate statutes. Regarding rental arrears, §§ 543 and 569 BGB outline two specific default scenarios:
- Default across two consecutive payment periods where the outstanding balance exceeds one month’s rent for standard residential tenancies.
- Over a period spanning more than two payment dates, arrears reach a total equivalent to two months’ rent.
These thresholds do not serve as a universal benchmark for ordinary notice. In cases involving breach of domestic peace, sustained disturbance, case-specific evidence, and an assessment of mutual interests are required; a single noise complaint does not trigger automatic lease termination. For contractual breaches, the statute generally mandates prior formal warning (Abmahnung) or a cure period, though exceptions apply, including for rent arrears.
If you receive a notice of termination, consult a local tenants’ association (Mieterverein) or specialized legal counsel without delay, bringing your lease, the notice, and payment records. Under §§ 543 and 569, payment histories, formal warnings, and cure options are critical; statutory thresholds alone cannot determine the outcome of a legal dispute.
6. Apartment Handover
An apartment handover protocol (Wohnungsübergabeprotokoll) records what was transferred and documents existing defects. There is no general statutory obligation to compile or sign a protocol, though specific contractual clauses must be verified (Mieterbund Rheinisch-Bergisches Land).
During move-in or move-out inspections:
- Describe the condition. Note visible damage to finishes, sanitary installations, windows, and doors, moisture marks, and any other defects found. Distinguish descriptions of existing condition from promises to perform remedial work.
- Take meter readings. Record values and serial numbers of accessible utility meters belonging to the unit: water, electricity, gas, and heat allocators, depending on installations.
- Count the keys. Specify the exact count and types of keys provided: apartment, building entrance, mailbox, cellar, and auxiliary doors.
- Take photographs. Capture overall room views, disputed areas, meter displays, and keys. Retain copies of the signed protocol and photos.
Do not sign a protocol describing conditions you dispute or containing obligations you do not intend to undertake. If an agreed joint protocol cannot be drafted, document conditions independently, preferably with an independent witness. These documentation practices are recommended by the Mieterbund Rheinisch-Bergisches Land and Mieterbund Darmstadt. The absence of a bilateral protocol does not forfeit tenant rights; standard wear and tear under § 538 BGB is not damage for which the tenant is liable.
What to Check Before Signing
- Who is named as the tenant and who is liable for rent payments.
- Which rooms, basements, and fittings are included in the lease.
- When the tenancy starts and when the contract can first be terminated.
- What the total monthly financial commitment is, including separately billed utilities.
- Whether operating costs are billed via prepayments or a flat lump sum.
- How the security deposit is calculated and whether it can be paid in installments.
- Which rent increase mechanism is included in the agreement.
- What clauses govern cosmetic work and minor repairs.
- Which house rules and annexes are formally incorporated into the agreement.
- How the property’s condition, meters, and keys will be documented.
