LIVE WHERE YOU WORK! Zoned I-1, 900 S Irwin Avenue Ext offers a rare combination of a completely rebuilt one-level home and excellent business potential—all on approximately 0.70 acres. The I-1 zoning, location next to an established commercial area, and detached flex building make this property especially attractive for buyers looking to operate a business close to home while keeping work and living spaces separate. The property may also offer future potential to be subdivided into two separate parcels, with one parcel potentially pursued for commercial use. The kitchen is the centerpiece of the home, featuring custom cabinetry, stone countertops, an oversized island, stainless steel appliances, a gas range with a statement hood, extensive workspace, and a walk-in pantry. It opens directly into the dining and living areas, creating a bright and inviting space for everyday living and entertaining. The living room offers abundant natural light, recessed lighting, and a fireplace. The primary suite features a vaulted ceiling, large windows, private exterior access, a walk-in closet, and a spa-inspired bathroom with a freestanding soaking tub, separate glass-enclosed shower, custom cabinetry, and designer tile. The additional bedrooms are spacious and filled with natural light, while the beautifully finished secondary bathroom includes a tiled tub and shower combination. Outside, the full front porch, mature trees, and level yard create a peaceful and private setting. Just steps from the main residence is a detached flex building—ideal for a home office, private studio, workshop, online business, creative space, or additional storage. This setup allows you to truly **live where you work** without bringing the workspace into your home. An additional storage building provides even more usable space. Municipal water and sewer, central heating and cooling, and convenient access to downtown Spartanburg, shopping, restaurants, and major roads complete the property. This is a rare opportunity to own a fully redesigned home with **I-1 zoning, business flexibility, and the ability to live and work from one property.** Any proposed business use, subdivision, expansion, or conversion of the detached building is subject to applicable zoning, permitting, and licensing requirements. Buyers should independently verify their intended use and subdivision potential with the appropriate local authorities.
