Property Description
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.
