About this page

Kentucky rent late fee law

Kentucky's residential landlord and tenant act, KRS 383.500 to 383.715 (in force only where a local government adopts it), contains no late fee provision, so it neither caps a late rent fee nor gives a grace period.

Read in full for this check: Kentucky Revised Statutes, chapter 383 (Rental of Property -- Forcible Entry and Detainer -- Uniform Residential Landlord and Tenant Act). Official source, read from the copy archived on 2026-10-02 · checked .

Before you send the late rent notice: it is a reminder letter about overdue rent and a late charge, not an eviction notice. A notice to pay rent or quit is a separate document, and Kentucky has its own rules for it. Nothing on this page is legal advice.

What Kentucky law says about invoice interest

the legal rate of interest is eight percent (8%) per annum, but any party or parties may agree, in writing, for the payment of interest in excess of that rate as follows: (a) At a per annum rate not to exceed four percent (4%) in excess of the discount rate on ninety (90) day commercial paper [...] or nineteen percent (19%), whichever is less, [...] where the original principal amount is fifteen thousand dollars ($15,000) or less; and (b) At any rate [...]
— KRS 360.010(1). Read it at the official source · row verified 2026-08-19.

Over $15,000: any rate. At/under $15,000: lesser of Fed 90-day CP discount+4 pts or 19%. Corp/LLC debtors can't plead usury, so the cap really bites only small sole-prop debts.
