Example
A tenant returns the keys on 10 March. The move-out inventory matches the move-in one. The landlord has until 10 April to return the €650 deposit. If they return it on 25 May, they are a month and a half late: two months started, i.e. a penalty of 2 × 10% × €650 = €130 to pay on top of the deposit.
The guide to the security deposit covers the deductions allowed and what to do in case of disagreement.
Frequently asked questions
What is the maximum security deposit in France?
One month's rent excluding charges for an unfurnished let (article 22 of the law of 6 July 1989) and two months' rent excluding charges for a furnished let (article 25-6). The deposit can't be revised during the lease or when it's renewed.
How quickly must the deposit be returned?
One month from the return of the keys if the move-out inventory matches the move-in inventory, two months if there are differences. Keys can be handed over in person or sent by registered letter.
What's the penalty for returning it late?
The amount still owed is increased by 10% of the monthly rent excluding charges for each month of delay started. This penalty isn't due if the delay is because the tenant didn't give their new address.
What can be deducted from the deposit?
Sums owed by the tenant and backed by evidence: unpaid rent or charges, repairs that are the tenant's responsibility, identified by comparing the inventories (on a quote or invoice), allowing for normal wear and tear. In a building with shared ownership (copropriété), the landlord can keep up to 20% of the deposit until the yearly accounts are approved, then settle within the following month.
