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.
What is the average cost of a garage conversion in SC?
For 2025, costs typically range from $18 to $50 per square foot. A basic bedroom conversion averages $10,000–$25,000, while a full ADU with a kitchen and bath can exceed $50,000.
Can I convert my garage into a bedroom in a flood zone?
Only if the floor is above the Design Flood Elevation (DFE). In coastal SC, if the garage is below this level, it can legally only be used for parking, storage, or building access.
What are the fire safety requirements under SC building codes?
According to the SC Residential Code, you must maintain a fire separation (usually 5/8-inch Type X gypsum board) between the conversion and any remaining garage or attic space. Openings from a garage directly into a bedroom are generally prohibited.
