What Maryland law says about late fees
Maryland caps residential late fees at 5% of the monthly rent. On a $1,000-a-month rental, the most a landlord may charge for one late payment is $50.
The cap is a ceiling, not a default: your lease must still state the fee, and you may charge less than the maximum. Charging more than the cap risks the excess being declared unenforceable — and in a dispute or an eviction case, an unlawful fee can undermine your whole position.
The exact Maryland rule: 5% of the unpaid rent, effective October 1, 2025 (HB 273). For weekly tenancies: $3 per week or $12 per month. No statutory grace period.
The Maryland grace period
Maryland sets no statutory grace period: if the lease allows a late fee, it may be charged as soon as the rent is late. Nothing stops you from writing your own grace period into the lease — many landlords allow a few days as a goodwill buffer — but the law does not require one.
Charging late fees in Maryland: putting it into practice
Three habits keep Maryland late fees defensible. First, put the exact fee in the lease before it is ever needed — you cannot invent a charge after the rent is already late. Second, apply it consistently and keep records: when rent was due, when it arrived, and what was charged. Third, remember that cities and counties can add their own rules on top of state law, so confirm local ordinances before relying on the statewide rule alone.

Frequently asked questions
What is the maximum late fee a Maryland landlord can charge?
The legal maximum is 5% of monthly rent. Your lease must still state the fee, and charging more than the cap risks the excess being unenforceable. The exact rule: 5% of the unpaid rent, effective October 1, 2025 (HB 273). For weekly tenancies: $3 per week or $12 per month. No statutory grace period.
Is there a grace period for late rent in Maryland?
No. Maryland sets no statutory grace period, so a fee allowed by the lease may be charged as soon as rent is late. You may still write your own grace period into the lease.
What if my lease charges more than the Maryland cap?
The excess may be unenforceable. The calculator above automatically reduces the allowable fee to the legal maximum of 5% of monthly rent — update the lease clause to match the cap rather than charging the higher figure.
Can I charge a late fee every day the rent is late in Maryland?
Generally, treat the late fee as a single charge per late payment rather than a daily penalty. A few states build per-day amounts into their caps (for example, Connecticut’s $5-per-day structure within its $50/5% ceiling, and Iowa’s tiered per-day limits) — follow the exact rule cited above and whatever your lease says, and never stack fees to punish.
