A Security Deposit Clause is a provision in a lease agreement that requires a tenant to provide a security deposit to the landlord as additional protection against default on the terms of the agreement. A security deposit is a sum of money, held by the landlord, as a form of protection against the tenant’s potential failure to pay rent, damages to the property, or other breaches of the lease agreement. If the tenant meets all the lease obligations, the security deposit is refunded at the end of the lease period. There are two types of Security Deposit Clause: refundable and non-refundable. A refundable Security Deposit Clause requires that the tenant pay a security deposit that is fully refundable at the end of the lease period, provided that the tenant meets all the lease requirements. A non-refundable Security Deposit Clause requires the tenant to pay a security deposit that is not refundable at the end of the lease period. This type of clause may be used to cover the landlord’s costs for repairs or cleaning at the end of the lease period.
