Downtown Santa Rosa Retail / Showroom / Creative Space - Two Immediate Suite Options Available: 3,900+/- SF or 7,410+/- SF 145 Third Street offers two practical, right-sized lease opportunities in the heart of Downtown Santa Rosa. The available suites can accommodate a range of retail, showroom, studio, service, wellness, fitness, creative office, or experiential concepts looking for a visible downtown location with character, volume, and immediate occupancy potential. Unlike larger downtown spaces that require a major commitment, these layouts provide more manageable footprints while still offering strong street presence, high ceilings, open-span areas, and functional back-of-house potential. The property sits near Railroad Square, Santa Rosa Plaza, hotels, restaurants, offices, transit, and Highway 101 access, giving tenants a central location with both local foot traffic and regional accessibility.
