Executive Summary
21 Broad Street offers a rare opportunity to own a fully renovated, income-generating historic property in the heart of downtown Charleston. Originally built in 1802 and completely updated in 2018 (with additional improvements in 2023), this 4,254 sq ft mixed-use building spans four floors and provides both commercial and residential income streams with unmatched versatility. The first floor features a professional office suite with a shared conference room and four private offices, ideal for business tenants or an owner seeking a prestigious Broad Street address. The second floor is a 2-bedroom residence operating as a successful short-term rental with a rare, grandfathered B&B license — a highly valuable asset in Charleston's tightly regulated market.
The top two floors are home to a spacious 3-bedroom, 2.5-bath apartment with updated kitchen and baths, perfect for long-term rental income or owner occupancy. Currently fully leased with tenants in place, the property produces over $265,000 gross ($200,000) net income annually. Additional highlights include two off-street parking spaces, updated systems and finishes throughout, and a prime location within walking distance to the Battery, White Point Gardens, award-winning restaurants, coffee shops, and galleries.
Whether maintained as a turn-key investment, converted to a live-work arrangement, or adapted for full owner occupancy, 21 Broad Street blends Charleston's historic charm with modern function and proven rental income.
