Maryland Late Fees: The 5% Cap & 15-Day Grace Period

Maryland enforces strict statutory limitations on how, when, and how much a landlord can penalize a tenant for paying rent late. Attempting to contract around these statutes with a customized lease clause is illegal and will be struck down by a District Court judge during eviction proceedings.

The 5% Maximum Cap

In Maryland, a late fee for residential rent can never exceed 5% of the amount of rent due for the rental period for which the payment was delinquent.

• If the monthly rent is $2,000, the absolute maximum late fee a landlord can charge is $100.
• Weekly rent: If rent is paid weekly, the late fee penalty cannot exceed $3 per week, or a total of $12 per month.
• Partial Payments: If a tenant makes a partial payment before the rent is officially late, the 5% late fee can only be applied to the remaining balance due, not the full rent amount.

Daily accumulating late fees (e.g., "$10 per day until paid") are strictly prohibited if the total surpasses the 5% cap for that month.

The Mandatory 15-Day Grace Period

Unlike states that cap late fees but allow them to immediately trigger on the 2nd or 5th of the month, Maryland mandates an extraordinarily long grace period.

A landlord cannot charge a late fee until the rent is 15 days past due.

If rent is due on the 1st of the month, the late fee cannot legally be applied until the 16th of the month. A tenant who pays on the 14th is late, but cannot be charged a financial penalty.

(Note: While landlords cannot charge a late fee until the 16th, they can still serve a 10-Day Notice to Pay or Quit before that. Arrears eviction timelines are distinct from late fee timelines.)

Lease Requirement

Even if the late fee falls within the legal limit (e.g., exactly 5%), a landlord cannot legally charge it unless the exact fee amount or percentage is explicitly stated in the written lease agreement.

Automatically Enforce Compliance

Tracking two separate timelines—when to serve a 10-Day Notice vs. when to accurately apply a 5% late fee on the 16th day—leads to administrative errors. Landager automates your Maryland ledger, automatically assessing the precise, legally capped late fee only after the 15-day grace period has fully expired.
