Rental security

The security deposit is the general term for all forms of security provided by a tenant to the landlord to ensure the tenant fulfills their obligations under the lease. In particular, it covers rent, claims for damages, and outstanding operating costs. The most common form is the rental deposit (cash deposit or savings account); in addition, bank guarantees, deposit insurance, and, in exceptional cases, guarantors are permitted. All forms are legally limited to a maximum of three months’ net rent.

Overview of Forms of Rental Security

The cash security deposit is the simplest form: The tenant transfers the amount; the landlord must deposit it in an account separate from their own assets. The security savings account in the tenant’s name (pledged to the landlord) is a secure option that allows the tenant to retain ownership of the security. The bank guarantee protects the landlord without the tenant having to tie up liquidity-the bank pays out in the event of a claim. Rental deposit insurance works similarly to a guarantee: the tenant pays a premium, and the insurer provides a guarantee to the landlord.

A rarely used but fundamentally permissible model is the personal guarantee-for example, provided by parents for students or by an employer for expatriates. This form offers the landlord an additional layer of security but is more difficult to enforce in practice than a bank guarantee: The guarantor must first be held liable, and the guarantor’s creditworthiness must be checked just as thoroughly as that of the tenant themselves.

Administration and Insolvency Protection

A frequently underestimated obligation: The security deposit must be held in a manner protected against insolvency. If it ends up in the landlord’s regular checking account, it can be included in the estate in the event of insolvency-the tenant loses their right to a refund. The law expressly requires a separate account. Landlords who fail to comply may be liable for damages. A professional property management company always maintains separate security deposit accounts.

The interest accrued on the security deposit account belongs to the tenant. After years of rising interest rates, this aspect is regaining importance: With a security deposit of 3,000 euros and an interest rate of 2%, 60 euros in interest accrues annually, which must be paid to the tenant upon return of the deposit. Landlords who retain this interest for themselves may be liable for damages.

Return and Offset

At the end of the tenancy, the security deposit must be returned as soon as the landlord no longer has any valid counterclaims. The return period is not precisely regulated by law; case law grants the landlord a reasonable review period of three to six months. Outstanding utility bills may extend this period. The landlord may only withhold amounts that are offset against claims that are due, undisputed, or legally established.

After the handover, the landlord should provide the tenant with a written statement detailing the use of the security deposit: Which amounts are being offset (with justification and proof), and what remaining balance will be refunded and when? This transparent communication prevents misunderstandings and significantly reduces the risk of disputes.

Practical Tip for Landlords in Nuremberg and Franconia

In Nuremberg, the security deposit settlement at the end of the lease is a frequent point of contention. We recommend that landlords create a photo-documented handover report upon move-in and use the same format upon move-out. This is the only way to clearly demonstrate which damages are attributable to the tenant and which constitute normal wear and tear. Proper documentation speeds up the security deposit settlement and prevents unnecessary disputes.

In practice, we observe that landlords who document professionally and settle accounts fairly are significantly less likely to become involved in legal disputes over the security deposit. Our property management clients benefit from a standardized handover process with a digital report that secures all relevant information and serves as evidence in the event of a dispute.

Frequently Asked Questions

As a landlord, can I require more than three months’ rent as a security deposit?

No. Section 551 of the German Civil Code (BGB) limits the security deposit to a maximum of three months’ net rent excluding utilities. Contract clauses requiring more are invalid. The tenant is nevertheless obligated to pay the maximum permitted amount.

Can the security deposit be increased during the tenancy?

Only if the rent increases and the originally agreed-upon security deposit (e.g., three months’ rent) is to be adjusted accordingly-provided this is contractually agreed upon. A unilateral increase by the landlord is not possible.

What constitutes a sufficient bank guarantee?

A bank guarantee must be issued by a solvent financial institution, be valid indefinitely or until the end of the tenancy, and be payable on first demand. Guarantees with restrictions or time limits may be worthless to the landlord in an emergency.

What happens to the security deposit when the property is sold?

The security deposit is transferred to the new owner along with the lease. The seller must hand over the deposit funds to the buyer; the buyer assumes the obligation to return them later. Buyers should explicitly stipulate the assumption of the deposit in the purchase agreement.

Can a security deposit insurance policy be more advantageous than a cash deposit?

For tenants with limited liquidity, rent guarantee insurance can be a sensible option: Instead of tying up 2,400 euros (e.g., two months’ rent at 1,200 euros in base rent) as a one-time payment, the tenant pays an annual premium of typically 3-6% of the guarantee amount-that is, 72 to 144 euros per year. The landlord receives the same security as with a cash security deposit, but bears the risk that the insurer may seek recourse from the tenant in the event of a claim. For landlords, security deposit insurance is equivalent provided it is issued by a solvent insurer with an indefinite term and an immediate payment commitment. We recommend that landlords carefully review the claim conditions for security deposit insurance-some insurers require a court ruling on the claim before payment, which can significantly limit the protective effect in everyday situations.

Practical Note: Security Deposit Management in a Condominium Association (WEG)

For condominiums managed by a WEG administrator, security deposit management nevertheless remains the responsibility of the individual landlord (the respective condominium owner), not the administrator. Mixing these funds with the WEG’s communal funds is prohibited. Owners in Nuremberg homeowners’ associations who rent out their units should therefore maintain separate security deposit accounts and ensure that the WEG administrator has no access to these accounts. Our market data for the metropolitan region shows that owners who clearly document this separation are in a significantly better position in the event of a dispute-both vis-à-vis the tenant and in the event of a dispute among owners within the WEG.
