What late fees can a landlord charge in Missouri?

Verified July 9, 2026 All Missouri topics →

Missouri sets no cap on residential late fees and mandates no grace period — no statute in the landlord-tenant chapters (RSMo 441 and 535) mentions late fees at all, so the fee is whatever the lease says, subject only to the court-enforced rule that a late fee must be a reasonable pre-estimate of the landlord's loss rather than a penalty.

Rent is due on the date the lease sets, and under RSMo 535.060 a landlord's demand for rent is valid any time after it comes due, so a lease-based late fee can begin the day after the due date. Two figures that circulate online do not apply to homes or apartments: the '$20 or 20 percent of monthly rent' safe harbor is RSMo 415.417, part of Missouri's Self-Service Storage Facilities Act covering storage units only, and claims that RSMo 535.060 'governs late fees' are wrong — that section is about when a demand for rent is valid and never mentions fees. A fee that appears nowhere in the lease has no contractual basis to be collected.

Missouri late fees at a glance

Statutory cap No statutory cap (see reasonableness standard and notes)
Mandatory grace period None mandated statewide
Must be in the lease Not addressed by statute
Daily fees No statute addresses residential late-fee structure at all; daily or flat fees are lease matters bounded only by common-law liquidated-damages/penalty doctrine. The '$20 or 20% of monthly rent, whichever is greater' figure that circulates in Missouri late-fee guides is RSMo 415.417, part of the Self-Service Storage Facilities Act (RSMo 415.400-415.425 by its own citation clause) — it governs storage units, not homes or apartments.
Reasonableness standard No statutory formula, percentage, dollar cap, or grace period exists for residential rentals — confirmed by a full read of the chapter 441 section index and chapter 535's landlord-tenant provisions. Enforceability rests on ordinary Missouri contract law: a late fee must be an agreed term, and courts police fees as liquidated damages, refusing enforcement of amounts that operate as penalties rather than reasonable pre-estimates of loss. RSMo 535.060 confirms rent is due 'according to the terms of the agreement' and a demand for rent is good any time after it accrues — no statutory grace period intervenes.

Notes and caveats

statutory_cap, grace_period_days, and must_be_in_lease are all null because Missouri has NO late-fee statute of any kind for residential rentals — must_be_in_lease is null rather than true because the in-writing requirement is a contract-law consequence (no agreed term, no fee), not a statutory command, and rule 1 forbids encoding it as a statutory true. Citations are anchors, not late-fee authority: 535.060 is cited because it fixes when rent is due/demandable (and because RentLateFee.com falsely presents it as Missouri's late-fee framework — read directly this session: it is titled 'Demand of rent good, when' and contains nothing about fees), and 415.417 is cited to debunk the storage-unit $20/20% figure (its containing act self-identifies as the Self-Service Storage Facilities Act in RSMo 415.400, read directly). The '4-5% is reasonable' figure on several sites is a practitioner rule of thumb with no Missouri statutory or reported-decision citation offered — page copy should not present any percentage as a Missouri rule.

Statute citations

How this record was verified: Direct read of statute text on the official Missouri Revisor of Statutes site (revisor.mo.gov): RSMo 535.300 read in full THREE times via independent fetches (all load-bearing figures — two months' cap, thirty-day return, written-notice inspection right, twice-the-amount-wrongfully-withheld penalty, subsection 8 definition — matched verbatim across reads), RSMo 441.060 and RSMo 441.043 each read twice (matched verbatim), plus single trap-check reads of RSMo 535.060 (demand of rent — confirmed it says nothing about late fees), RSMo 415.400 and 415.417 (confirmed the $20/20% late-fee figure belongs to the Self-Service Storage Facilities Act, not residential rentals), RSMo 441.233 (unlawful ouster), RSMo 441.065 (abandonment entry procedure), and the full chapter 441 section index (confirmed no entry-notice, late-fee, or rent-increase-notice section exists). 2026 regular session Truly Agreed To and Finally Passed list (102 bills) checked on senate.mo.gov 2026-07-09 — no landlord-tenant bills passed; the 2025 amendments to 441.043 (H.B. 595 & 343, effective 2025-08-28) are already law and are incorporated, not flagged.
