The Automatic Security Deposit Increase Provision

The AIR leases contain an often overlooked Security Deposit provision. When there is an increase in the Base Rent, the Security Deposit increases proportionately. Therefore, if Base Rent increases by 3%, the Security Deposit also increases by 3%.

Tip: If you represent a tenant, consider informing the tenant of this provision during lease negotiations. At the minimum, advising the tenant of this provision will prevent the tenant from being surprised by the increase. In this way, you may avoid harming your relationship with the tenant.

      Thank you for your comment. I agree that it is frequently overlooked by landlords. A few of my landlord clients do enforce it.

    Good article, as usual, Usman. In San Diego office leasing, the Security Deposit is often equal to the last month of scheduled rent, which is even more favorable for landlords. For strong credit tenant, however, there is usually no deposit required.
