Frequently Asked Questions
Do I need a permit for a garage conversion in South Carolina?
Yes. Most SC jurisdictions require a building permit for any project over 200 square feet or any project involving electrical, plumbing, or structural changes. You will also likely need a zoning permit.

Can I convert my garage into a bedroom in a flood zone?
