Commercial property leasing in South Korea is governed by the Commercial Building Lease Protection Act, which provides tenant protections distinct from those available under the residential Housing Lease Protection Act. With longer renewal periods, key money (gwolligeum) protection, and unique converted deposit thresholds, commercial landlords must navigate a specialized regulatory landscape.

Converted Deposit (Hwansan Bojeunggeum)

Calculation

Some protections under the Act apply only when the converted deposit falls below regional thresholds. The formula is:

Converted Deposit = Security Deposit + (Monthly Rent × 100)

Regional Thresholds

RegionThreshold
Seoul₩900 million
Overcrowding Control Zones / Busan₩690 million
Metropolitan cities (excl. rural areas) / Sejong / Paju / Hwaseong₩540 million
Other areas₩370 million

Rights That Apply Regardless of Converted Deposit

Even when the converted deposit exceeds the regional threshold, the following rights are guaranteed to all commercial tenants:

  • Opposing power (delivery + business registration)
  • Contract Renewal Request Right (10 years)
  • Key money recovery protection
  • Rent increase/decrease request rights
