House Bill 273: Fairer Late Fees

October 1, 2025

Landlords can no longer charge late payment penalties based on the full rent amount.


Maryland already capped late rent penalties at 5%, but some landlords applied that percentage to the entire month’s rent, even if most had already been paid.


What’s new: Landlords must now calculate late fees only on the unpaid portion of rent. Weekly leases remain capped at $3/week, with a $12/month maximum.

Example: Rent is $1,000, a tenant pays $800 on time, $200 is late. Before: fee could be $50. Now: fee maxes at $10.


As a result of the new law, tenants who make partial payments will not be over-penalized. Landlords will need to revise lease forms, and unenforceable clauses could lead to tenant lawsuits for damages and attorney’s fees.
