Want late fees calculated and capped automatically?

Rentari.ai is all-in-one property management software for landlords and property managers of all sizes that scales as you grow. Price the late fee the way your lease writes it: a flat dollar amount, a percent of the monthly rent, or a percent of the rent still unpaid. Every fee is then held under your state's statutory limit, and under an optional cap on the total late fees a single lease can charge across its whole term. Rentari.ai applies the correct grace period, assesses at most one late fee per lease per month, and drafts state-specific leases that pass this check automatically. Free Forever for unlimited units with tenant screening included; lease creation and rent collection unlock on Prime.

FAQ

The questions landlords actually ask about late rent fees.

How much can a landlord charge for a late fee?
It depends on the state. Some states cap late fees at a percentage of monthly rent (commonly 5 to 10 percent), some cap a flat dollar amount, and many have no statutory cap at all but still require the fee to be reasonable rather than a punitive penalty. Pick your state above to see the specific rule and grace period.
Is a late fee legal if there is no grace period?
Several states require a grace period (often 5 days) before any late fee can attach, and a fee charged on day one in those states is unenforceable. Where state law is silent, the lease controls, but a written grace period of a few days is standard and heads off disputes. The calculator shows the required grace period for your state.
What happens if I charge an illegal late fee?
In states with a statutory cap, a fee over the cap is generally unenforceable, and a tenant can refuse to pay the excess or recover it, sometimes with statutory damages. Even in no-cap states, courts routinely strike late fees they consider punitive rather than a reasonable estimate of the landlord's actual cost. Keep the fee modest and tied to real cost.
Can I charge a daily late fee?
A few states allow a per-day late fee up to a stated cap, but most require a single flat or percentage fee. A compounding or open-ended daily fee is a common way to end up over the line. Check the linked statute for your state before using a per-day structure.
Does the late fee have to be in the lease?
Yes. A late fee is only enforceable if it is written into the signed lease. You cannot impose or raise a late fee mid-term that the tenant never agreed to. Put the amount, the grace period, and when it attaches in the lease itself.
Where does the source data come from?
From the state landlord-tenant statutes themselves. Rentari.ai maintains a verified catalog of each state's late-fee rule, grace period, and the official statute URL, shown alongside every result. Updated periodically. If you spot a discrepancy with the linked statute, email [email protected].
