A security deposit (Kaution or Mietsicherheit) is the primary financial protection available to Hamburg landlords against unpaid rent or tenant-caused damage. While German law gives landlords the right to collect a deposit, it places strict rules on the maximum amount, how it must be held, and when it must be returned. These rules are governed by the German Civil Code (Bürgerliches Gesetzbuch – BGB), which originally came into force on 1 January 1900, specifically § 551 BGB. Violations can result in tenants withholding rent or taking legal action.

Maximum Deposit Amount
Under § 551 BGB, residential security deposits in Hamburg are capped at:
- Maximum 3 months' net cold rent — "net cold rent" means the base rent excluding all utility charges (Betriebskosten) billed as advances or flat fees.
- If rent increases later (e.g., after a legitimate rent increase), the landlord cannot demand a top-up to bring the deposit in line with the new rent.
Tenant's Right to Pay in Installments
The landlord cannot demand the full deposit upfront before handing over the keys
By law, tenants have the right to pay the deposit in three equal monthly installments. The first installment is due at the start of the tenancy.
How the Deposit Must Be Held
This is one of the most error-prone areas for Hamburg landlords
The deposit must be:
- Kept separate from the landlord's own assets — held in a trust account (Treuhandkonto) that is protected from the landlord's creditors in the event of insolvency.
- Invested at the standard savings interest rate for deposits with a 3-month notice period (§ 551 Abs. 3 BGB).
- All earned interest belongs to the tenant — it increases the security and must be returned to the tenant at the end of the tenancy.
Alternatives: Landlords and tenants may agree in writing to alternative forms of security, such as a pledged savings account, a bank guarantee letter (Bankbürgschaft), or an investment deposit account. Bank guarantees are particularly common because they don't lock up tenant liquidity.
If the landlord does not hold the deposit correctly: The tenant may withhold monthly rent payments up to the value of the demanded deposit until the landlord proves compliance.
Permitted Deductions
After the tenancy ends, the landlord may retain part or all of the deposit only for legitimate claims arising from the rental relationship:
: Damage from normal wear and tear (e.g., minor scuffs on walls, light carpet wear) is considered the landlord's responsibility and cannot be charged to the tenant.
Return Timeline German law does not specify an exact return deadline in days
Instead, courts grant a reasonable review-and-decision period, which is typically:
- 3 to 6 months after the premises are handed back (keys returned), to allow inspection and identification of claims.
- If the annual service charge statement is still outstanding, the landlord may withhold a proportionate portion (usually 3–4x the monthly advance) until the final statement is issued.
After any valid deductions are settled, the remaining deposit plus all accrued interest must be returned promptly.
Consequences of Non-Compliance
- Failure to hold the deposit in a separate insolvency-protected account: tenant may withhold rent until compliance is proven.
- Unjustified withholding after the end of tenancy: tenant may sue for return of deposit plus compensation costs.
- Courts in Hamburg consistently rule against landlords who attempt to draw on deposits for items that are ordinary wear and tear.
Disputes and Jurisdiction
In the event of a dispute regarding the security deposit or its return, the local Amtsgericht Hamburg (or the respective local court where the property is located) has exclusive jurisdiction regardless of the amount in dispute (§ 23 Nr. 2a GVG; § 29a ZPO).
