Maryland Commercial Late Fees: Uncapped Penalties & Default Interest

Unlike Maryland's highly protective residential housing codes—which mandate a 15-day grace period and cap late fees at a strict 5% limit—the state imposes zero restrictions on late fees for commercial real estate properties.

No Statutory Limitations

A commercial lease is viewed under Maryland law as a binding contract between two sophisticated business entities. If the tenant agrees to severe financial penalties for paying rent late, the court will enforce them.

There is:

• No mandatory grace period: A late fee can be charged on the 2nd day of the month if the lease states rent is due on the 1st without exception.
• No maximum percentage cap: A landlord can legally charge a 10% or 15% late fee if it is stipulated in the signed contract.

Two-Tiered Penalty Structures

To protect cash flow and adequately penalize chronic delinquencies, sophisticated Maryland commercial leases employ a two-tiered penalty strategy when a tenant defaults on rent:

1. The Immediate Administrative Late Fee

A flat rate or percentage penalty designed to cover the landlord's administrative headache in tracking down the payment.

• Example clause: "If rent is not received by the 5th day of the month, Tenant shall pay an immediate late charge equal to 5% of the outstanding balance."

2. Default Interest Rates

Because a late commercial rent payment essentially forces the landlord to act as an uncompensated bank, the lease will stipulate that any outstanding balances accrue heavy interest until paid in full.

• Example clause: "Any amount not paid when due shall bear interest at an annual rate of 12%, or the maximum rate permitted by Maryland law, whichever is less, calculated daily from the due date until paid in full."

Non-Waiver of Default

Smartly drafted commercial leases in Maryland contain a "Non-Waiver" clause. This ensures that if a landlord accepts rent late one month without charging the mandated 10% late fee, the landlord has not fundamentally altered the contract or waived their right to strictly enforce the late fee deadline the following month.
