Frequently asked questions
How much can a landlord charge for a late rent payment?+
It depends on the state. Some cap late fees at a percentage of rent (e.g. Maine 4%, Nevada 5%) or a flat amount (New York: the lesser of $50 or 5%); many states have no fixed cap but require the fee to be reasonable. Pick your state for the exact limit.
Can a late fee be higher than the state cap if it's in the lease?+
No. A lease term setting a late fee above the legal limit is generally void and unenforceable.
