Rent Late Fee Limit in Missouri
The most a landlord can charge you for paying rent late in Missouri, the grace period you may be owed, and what to do about an unfair fee, cited to the statute.
The cap and the grace period in Missouri
The most a late fee can be, when it can be charged, and whether it has to be in your lease.
Missouri does not set a maximum late fee by statute. A late fee still has to be a reasonable estimate of what the late payment actually costs the landlord; a fee that works like a penalty can be challenged as an unenforceable penalty, even without a fixed percentage in the law.
| Maximum late fee | Missouri sets no cap, no grace period, and no overcharge penalty. The only limit on the amount is the general contract rule that the fee be reasonable. The protection that makes the page is elsewhere: Mo. Rev. Stat. 535.020 lets a landlord join a claim for other unpaid sums in a rent action, however denominated in the lease, provided those sums are not considered rent for purposes of the chapter. So a Missouri late fee can be sued for, but it cannot support possession. |
| Grace period | No statutory grace period. A late fee applies once rent is late, subject to your lease. |
| Must be written in the lease | A late fee is enforceable only if your lease provides for it. Check the lease first. |
| Local ordinance | St. Louis and Kansas City ordinances should be checked, but the state rule, that late fees are not rent for eviction, is the operative protection. |
| How it is enforced | The key protection is that unpaid late fees cannot support an eviction in Missouri, because they are not rent for purposes of the chapter. A landlord may still sue for the fee as a separate money claim, so it is a debt rather than a ground to lose the home. There is no priced penalty for an excessive fee, so an outsized one is challenged as an unenforceable penalty. |
| Statute | No late-fee cap statute; governed by case law |
What you can do right now
Concrete, neutral steps if a Missouri late fee looks too high or came with no grace period. This is legal information, not legal advice.
- Know that late fees cannot cost you the home
Missouri treats other sums as not rent for eviction purposes, so an unpaid late fee cannot support a nonpayment eviction. A landlord can sue for it separately, but it is a debt, not a ground to be removed.
- Read your lease late-fee clause
Because no statute caps the amount, the lease is the rule. Note the fee and whether it repeats, though it will be treated as a debt rather than rent.
- Challenge an outsized fee as a penalty
Without a cap, the limit is reasonableness. A fee far larger than any plausible cost can be argued to be an unenforceable penalty, so keep your lease and receipts.
- Get local help
A local Missouri legal aid office can confirm the treatment of your fee and any city rule. Search for legal aid in your area.
This is general legal information, not legal advice. Read your own lease and check for a local ordinance, since either can change the fee that applies to your home.
What Missouri renters get wrong
Missouri and Delaware answer the same question in opposite directions, and the difference decides whether a renter keeps their home. Delaware says a late charge is considered as additional rent, so it can drive an eviction. Missouri says other sums are not considered rent for purposes of the chapter, so it cannot. Under Mo. Rev. Stat. 535.020 a landlord may join a claim for unpaid sums other than rent in a rent action, however the lease labels them, but those sums are not rent for the chapter, which means an unpaid late fee is a debt the landlord can sue for rather than a ground to remove the tenant. Missouri caps nothing, sets no grace period, and prices no penalty, yet it gives renters the more important protection of the two, because losing the home is a graver consequence than paying a fee. For a renter that means the lease sets the amount, the fee is a debt, and an outsized one can still be challenged as an unenforceable penalty, but it will not by itself support an eviction.
Common questions
Can I be evicted in Missouri over unpaid late fees?
No. Mo. Rev. Stat. 535.020 treats sums other than rent as not rent for purposes of the chapter, so an unpaid late fee cannot support a nonpayment eviction. The landlord can sue for it as a separate debt, but not remove you over it.
Is there a cap in Missouri?
No. Missouri sets no cap, no grace period, and no overcharge penalty. The only limit on the amount is the general rule that the fee be reasonable, so an outsized fee can be challenged as an unenforceable penalty.
Can the landlord sue for the fee separately in Missouri?
Yes. A landlord may join a claim for unpaid late fees in a rent action, but because those sums are not rent for the chapter, the fee is pursued as a debt rather than as a basis for possession.
What counts as rent in Missouri?
For the eviction chapter, rent does not include sums other than rent, even if the lease labels them rent. That is why late fees, however denominated, are not rent for possession purposes under Mo. Rev. Stat. 535.020.
