The "Kaution" in Hesse is strictly governed by the German Civil Code (BGB), which has been in effect since 1 January 1900. Landlords must act as trustees, ensuring funds are held safely and returned promptly once all legal obligations have been met.
The security deposit (Mietkaution) is one of the most important security instruments for landlords in Hesse. Federal law (BGB) uniformly regulates maximum amounts, payment methods, and the obligation to invest the deposit separately. This guide provides a detailed overview of your rights and obligations as a landlord.
Deposit Rules at a Glance
Maximum Deposit Amount
The deposit is calculated based on the net cold rent (Nettokaltmiete) - excluding utility and heating cost prepayments
For example, if the monthly cold rent is €900, the maximum deposit is €2,700. The landlord may not demand more than three months' cold rent. Any amount exceeding this limit is unenforceable.
Payment in Installments
The tenant has the legal right to pay the deposit in three equal installments
The first installment is due at the start of the tenancy, with the second and third due alongside the following two rent payments. The landlord cannot make move-in conditional on the full deposit being paid upfront.
Investment and Safekeeping
Landlords in Hesse must invest the deposit separately from their own assets at the usual interest rate for savings deposits with a three-month notice period. The contracting parties may agree on a different form of investment, but in all cases, the investment must be separate from the landlord's assets. The proceeds belong to the tenant and increase the security. For residential space in a student or youth dormitory, the landlord is not obliged to pay interest on the security deposit.
Common options include:
- Savings account in the tenant's name
- Dedicated deposit account (Mietkautionskonto)
- Savings book (Kautionssparbuch)
The accrued proceeds belong to the tenant and increase the security amount. If the landlord fails to invest the deposit properly, the tenant may withhold rent payments equal to the deposit amount until proof of proper investment is provided.
Alternative Forms of Security
Other forms are acceptable if the tenant agrees:
- Bank guarantee (Mietaval / Bankbürgschaft)
- Deposit insurance (Mietkautionsversicherung)
Returning the Deposit
Review Period
After the tenancy ends and the property is returned, the landlord has a reasonable review and accounting period - typically 3 to 6 months
A July 2024 BGH ruling (VIII ZR 184/23) confirmed that landlords may set off damage claims against the security deposit even after the six-month limitation period (§ 548 BGB) has expired, provided the claim was not yet barred at the time it could first be set off (§ 215 BGB).
Permitted Deductions
The landlord may withhold part or all of the deposit for:
- Outstanding rent payments
- Utility bill settlements (including from pending annual statements - partial retention is allowed)
- Damage compensation for damage beyond normal wear and tear
- Repair costs caused by the tenant
Best Practices for Landlords
- Document the property's condition thoroughly at move-in and move-out (handover protocol with photos)
- Invest the deposit immediately in a separate account and keep proof
- Process the deposit return promptly - ideally within three months
- Only retain justified amounts and itemize deductions clearly
- Inform the tenant about the deposit account and its balance
Common Mistakes to Avoid
- Failing to separate the deposit from personal assets → tenant can withhold rent
- Demanding more than 3 months' cold rent → excess is unenforceable
- Delaying deposit return unreasonably → risk of losing retention rights
