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.
