Brandenburg Security Deposit Laws: Limits, Returns, and Rules

Regulations regarding security deposits (Mietkaution) in Brandenburg are governed uniformly at the federal level by the German Civil Code (BGB). Landlords must adhere to strict capping and investment rules.

Statutory Maximum Limit

According to § 551 BGB, the security deposit for residential properties may not exceed three times the monthly rent, excluding flat rates or advance payments for operating costs (utilities). In other words, the legal limit is 3 months of net cold rent (Nettokaltmiete).

Installment Payments

The landlord cannot demand that the deposit be paid in full all at once. The tenant has the statutory right to pay the deposit in three equal monthly installments. The first installment is due at the start of the tenancy (upon handing over the apartment), and the remaining two installments are due with the immediately following rent payments.

Landlord's Investment Obligation

Landlords are legally obligated to invest a cash deposit separately from their own assets. It must be held in an escrow account at a financial institution, earning the customary interest rate for savings deposits with a three-month notice period. The accrued interest belongs to the tenant and increases the security deposit amount.

If the landlord fails to hold the deposit in an insolvency-proof manner, they commit a breach of duty and may be liable for damages. In such cases, the tenant also has the right to withhold ongoing rent payments up to the amount of the deposit until the issue is rectified.

Allowable Deductions

The deposit serves to secure all the landlord's claims arising from the tenancy. At the end of the lease, the landlord may use the deposit to settle justified claims. Permissible deductions include:

1. Unpaid Rent: Outstanding rent payments or compensation for use.
2. Utility Cost Adjustments: If a utility bill settlement is still pending, the landlord may withhold a reasonable portion of the deposit (usually equivalent to the expected additional payment based on past bills).
3. Property Damage: Costs for repairing damage that exceeds normal wear and tear (§ 538 BGB) and was caused by the tenant.
4. Unfinished Cosmetic Repairs: If the tenant was obligated to perform cosmetic repairs and failed to execute them properly upon moving out.

Important: The landlord may not deduct from the deposit for normal wear and tear (e.g., minor scuffs or worn carpets after a multi-year tenancy).

Deadline for Returning the Deposit

German law does not specify a rigid deadline for returning the deposit. However, according to established case law from the Federal Court of Justice (BGH), the landlord is granted a reasonable period for consideration and review (Überlegungs- und Prüfungsfrist). This period generally lasts three to six months after the end of the tenancy and the tenant's move-out.

If there are still outstanding claims that cannot yet be quantified (such as a pending annual utility bill), the landlord may retain a reasonable portion of the deposit beyond this period until the costs are finalized.

Upon disbursement, the landlord must provide a full accounting of the deposit and the accrued interest.
