Effective from 1 January 2003, the Commercial Building Lease Protection Act governs commercial tenancies in South Korea. Late rent fees for commercial leases are subject to a higher statutory interest rate than residential leases, and the termination threshold is strictly set at 3 months of arrears (cumulative) rather than the residential standard of 2 months.
Interest Rates
Statutory Rate (No Contractual Rate)
Commercial leases are classified as commercial (business) transactions, so the Commercial Act rate of 6% applies rather than the Civil Act rate of 5%.
Contractual Rate
Lease agreements may specify a higher rate. Rates of 10%–20% per annum are common in commercial lease practice.
Legal Cap
Calculation
Late fee = Overdue rent × Annual rate × (Days overdue / 365)

3-Month Arrears and Termination
Post-Termination Considerations
- 3-month arrears is also a renewal refusal ground (Art. 10(1))
- Deposit return obligation persists (simultaneous with vacating)
- Arrears may be deducted from the deposit
- Key money protection is lost if the tenant has 3 months of arrears (Art. 10-4(1))
Management Fee Arrears
Dispute Resolution

- Legal Weight: Mediated agreements have the same effect as a judicial settlement
Best Practices for Landlords
- Specify a late fee rate in the lease — the statutory 6% may not provide adequate incentive for timely payment
- Stay within the 20% cap — rates exceeding the Interest Limitation Act are void
- Track cumulative arrears precisely — the 3-month threshold is cumulative (CBLPA Art. 10-8)
- Separate rent and management fees in records — distinct billing for proper legal treatment
- Serve notice via Content Certification Mail — creates legal proof of termination notice
- Deduct arrears at lease termination — simultaneous with premises restoration
