Security deposit and guarantor: two concepts not to be confused
As you know, a residential lease is a rental contract for a property signed between the owner on one side and the tenant on the other. In this context, the landlord is entitled to require two things from the future tenant before they move into the property: consent to a security deposit and the provision of a guarantor.
Distinguishing between them is essential to fully understand the rights and obligations of each party. In practice, a landlord may require both a security deposit and a guarantor, provided applicable rules are respected. For tenants, understanding this difference helps anticipate the amounts to be paid and the commitments required at the time of renting.
What is a security deposit?
The security deposit is a sum paid by the tenant when signing the lease agreement.
The amount held as a deposit is not intended to cover routine unpaid rent, but to compensate for:
- any damage caused to the rented property,
- outstanding charges at the end of the lease,
- or breaches identified when the property is returned.
Throughout the duration of the lease, this deposit remains the tenant’s property. Once the contract ends, it must be returned within the legal timeframe, minus any amounts lawfully retained and duly justified by the landlord.
Its amount is regulated by law and depends in particular on the type of rental (unfurnished or furnished). It therefore constitutes a strictly regulated financial safeguard.
What is a guarantor?
The guarantor operates on a different principle. It is not a sum paid in advance, but a commitment made by a third party, known as the guarantor, who agrees to step in for the tenant in the event of non-payment.
This commitment takes the form of a joint and several guarantee agreement or a simple guarantee, whereby the guarantor undertakes to pay rent, charges, and any other sums due if the tenant defaults. The guarantor therefore represents a personal guarantee based on the financial solvency of a third party rather than on a blocked sum.
Unlike the security deposit, the guarantor’s commitment is not limited by the lease duration alone. It may be activated at any time if the tenant fails to meet contractual obligations.
How does the security deposit work?
The security deposit is collected by the landlord when the lease is signed and before the tenant moves in, and it is retained throughout the tenancy. Its amount is equal to one month’s rent excluding charges for an unfurnished rental, and two months’ rent excluding charges for a furnished property, as provided by the law of 6 July 1989.
The landlord may not use it freely or retain it without justification: its use is strictly regulated and limited to specific situations, including damage, unadjusted charges, or sums remaining due after the tenant’s departure. Any deduction must be duly justified.
At the end of the lease, the deposit is returned after comparing the move-in inventory with the move-out inventory. Two situations may arise:
- If no issues are identified, the full amount must be returned to the tenant within the legal timeframe. Payment must be made no later than two months after the tenant’s departure, starting from the return of the keys.
- If deductions are made, the landlord must justify each amount retained with precise documentation, such as invoices or estimates. The security deposit cannot serve as a penalty, and the landlord may not retain it without valid grounds.
It is therefore important to know how to carry out a thorough move-out inspection to limit the risk of disputes and legal proceedings.
How does a guarantor work?
A guarantor is based on a personal commitment made by a third party, distinct from the tenant, who agrees to assume the financial obligations provided for in the event of default. This commitment is formalized through a signed document at the time of letting or when the lease is executed.
There are two types of guarantor:
- A joint and several guarantor allows the landlord to request payment directly from the guarantor in the event of unpaid amounts.
- A simple guarantor requires the landlord to first attempt recovery from the tenant before calling upon the guarantor.
The guarantor’s commitment applies for the duration specified in the contract. It may be time-limited or cover all sums due until the end of the lease, depending on the terms of the signed agreement.
Clearly distinguishing the security deposit from the guarantor makes it easier to approach a rental with clear reference points and helps prevent misunderstandings between tenant and landlord. These two mechanisms follow different legal logics but pursue the same objective: securing the lease agreement in the interest of both parties and providing stronger protection for the landlord.
For any rental project, it is advisable to seek support from professionals, particularly a real estate agency specializing in property management: this is an essential asset for securing the transaction and establishing the foundations of a smooth relationship between landlord and tenant.
