Building Use Change Permit in Korea — 2026 Complete Guide

1. What Is a Building Use Change?

Under Korea's Building Act (건축법), every building has a designated use (용도). Changing the use — for example, converting an office to a restaurant — requires a government permit or report depending on the scope of the change.

2. Use Classification Groups

Korea classifies buildings into groups. Moving between groups (e.g., Group 1 단독주택 to Group 2 공동주택) typically requires a permit. Moving within a group may only require a report.

3. When Permit vs. Report is Required

• Permit (허가): changing to a use in a higher-tier group or changing to certain restricted uses
• Report (신고): minor changes within the same group or to lower-tier uses
• When structural changes accompany the use change, a construction permit may also be needed

4. Zoning Compatibility

• The new use must be permitted under the current zoning designation
• Example: Converting a residence to a restaurant in a purely residential zone is typically not permitted
• Always check with local planning authority before proceeding

5. Required Documents

• Building use change application or report form
• Building register (건축물대장)
• Architectural drawings of the building
• Proof of fire safety compliance for the new use
• Owner's consent (if applicant is a tenant)

6. Application Procedure

1. Verify zoning permits the intended use
2. Submit application/report to local city/county office
3. Document review and inspection (if required)
4. Updated building register issued reflecting new use
