No Statutory Cap
Kentucky imposes no specific maximum on commercial late fees. The only constraint is general contract law:
- Fees must be reasonable and proportionate.
- Excessive fees may be deemed unenforceable penalties.
- 4–5% of monthly rent is generally considered a safe threshold.
- Fees exceeding 10% may face scrutiny.
No Mandatory Grace Period
Kentucky law does not require a grace period for commercial rent. Rent is due on the date specified in the lease. Most leases include a 3 to 5 day grace period as a practical matter.
Common Fee Structures
| Structure | Example | Risk Level |
|---|---|---|
| Flat fee | $100–$500 per late payment | Low |
| Percentage | 5% of monthly rent | Low |
| Daily accrual | $50/day after grace period | Moderate |
| Tiered | 3% first week, 5% thereafter | Moderate |
Default Interest
Many Kentucky commercial leases include default interest on past-due amounts, separate from the late fee. Kentucky's usury statute caps general interest at 8% per annum unless the parties agree otherwise in writing — and commercial parties frequently agree to higher rates (10–12% is common).
Lease Drafting Best Practices
- Define late fees clearly — amount, trigger date, and collection method.
- Include a grace period — 3–5 days demonstrates reasonableness.
- Define late fees as "additional rent" — enables collection through the eviction process.
- Separate late fees from default interest — clearly distinguish the one-time fee from ongoing interest.
- Keep fees proportionate — 4–5% of monthly rent is the defensible standard.
