Security deposit for flat rental: what is the maximum amount and how does it work?

What is a security deposit and why do landlords require it

A deposit, commonly also referred to as a security deposit, is a sum of money that the tenant pays to the landlord upon signing the tenancy agreement. It serves as security in case the tenant fails to pay rent or service charges, or causes damage to the flat. Agreeing on a deposit is not mandatory by law, but it is a standard part of a flat tenancy agreement.

How much may a tenancy deposit for an apartment amount to

The amount of the security deposit is not arbitrary. According to Section 2254 of the Civil Code, the security deposit together with any contractual penalty may in total amount to no more than three times the monthly rent. If the contract includes a contractual penalty (for example for late payments) in addition to the security deposit, both are counted towards the same limit: the two amounts combined must not exceed this threshold.

If the contract stipulates a higher security deposit, this is an agreement that goes beyond the law. In such cases, it is advisable to first discuss the situation with the landlord and, in the event of disagreement, consult a lawyer who will assess the specific wording of the contract.

The purpose of the statutory cap is clear. It prevents landlords from demanding an unreasonably high amount from tenants. In practice, many landlords request a deposit lower than the legal maximum. The deposit amount is always a matter of agreement between both parties; the law only sets the upper limit that cannot be exceeded.

Security and advance payment for services: what is the difference?

It is advisable to distinguish the security deposit from utility advance payments, i.e., payments for water, electricity, gas or heating that the tenant pays regularly in addition to the rent. While the security deposit is a one-off sum paid at the start of the tenancy and returned (possibly reduced by debts) only after its termination, utility advances are settled regularly based on actual consumption. The rental agreement should clearly distinguish between both items to avoid confusion over what is refunded to whom and when.

Interest on the principal amount

The security deposit is not merely interest-free "held" funds. Upon its return, the tenant has a right to interest on the security deposit, at least at the statutory rate. The rationale is straightforward, during the tenancy period, the landlord had the funds available, and therefore the tenant is entitled to compensation. The specific interest rate agreed upon above the statutory framework can be adjusted by the contract even more favourably for the tenant.

Return of security deposit and set-off of debts

Upon termination of the tenancy, the landlord is obliged to return the security deposit. However, they may simultaneously offset any debts incurred by the tenant: typically unpaid rent, arrears on service charges, or costs for repairs of damage caused by the tenant to the flat. The amount returned is therefore the difference between the paid security deposit (increased by interest) and legitimately offset claims.

To ensure the deduction proceeds without unnecessary disputes, it is advisable to have a comparison of the flat's condition upon move-in and move-out. This is what serves that purpose. flat handover protocol, which we cover in a separate article. If the tenant disagrees with the amount deducted, it makes sense to first request a written breakdown and, in case of dispute, consider consulting a lawyer.

Practical advice on handing over money

The actual payment of the security deposit is a sensitive matter. It involves an amount that the tenant entrusts to another person for the entire tenancy. It is therefore worthwhile to pay attention to how and to whom the deposit is paid, and to document the entire process afterwards. Several recommendations on how to practically handle the security deposit when renting an apartment:

• Pay the deposit non-cash to the landlord's account, not in cash: a bank transfer is easily verifiable proof of payment.
• Please state the purpose of payment (security deposit for tenancy agreement) and the flat address in the payment reference.
• Keep the proof of payment or bank statement for the entire duration of the tenancy.
• Agree in advance in the contract on which account and by what method the security deposit will be returned after the tenancy ends.
• Before making payment, verify that the funds are actually going to the landlord, i.e., the apartment owner or a person authorised by them, and not to someone with no connection to the property.
• All communication regarding certainty, agreements, possible changes, requests for refunds, should be conducted in writing, by email or text message, not just verbally.
• In case of any uncertainty regarding the method of deposit custody, ask the landlord directly, transparency prevents disputes.

A security deposit is intended to protect both parties in a tenancy agreement: the landlord against non-payment and potential damages, and the tenant against arbitrary withholding of funds. Knowledge of basic rules (maximum amount, right to interest, principle of set-off) helps resolve any disputes factually, without unnecessary emotion. A combination of a written contract, a clearly agreed deposit amount and well-managed communication is the best prevention against disputes at the end of the tenancy.
