1147 Marsh Street

Welcome to the Ross Building - A luxury midcentury modern office building overlooking the San Luis Obispo creek and quietly tucked away in the northern part of the Downtown Historic District. This dream location offers a rare combination of turn-key professional space that feels more like a custom home than a work environment. The original structure was designed and built by nationally acclaimed local architect John R. Ross, who perfectly married local materials with an iconic design that is still modern to this day. The multi-unit property features stunning creekside views, lush landscaping and mature trees, and seamless indoor-outdoor spaces that elevate the workday experience. The location offers generous street parking and nearby city lots—a rarity for the downtown area. The building comprises 5 distinct office units with a grand total of 5 private closed-door office rooms, 3 bathrooms, 6 oversized general-flex rooms, 3 balconies, 2 patios, and a secure garage/storage room. Each office unit can be operated/leased independently or utilized as one cohesive space. The Ross Building places you just steps away from Downtown SLO and its vibrant local cafes, retail, and dining. Ideal for a professional firm seeking a high-end corporate headquarters, an investor seeking rental income, or a combination of both. The existing tenants and owner-operator are open to leaseback arrangements following the sale, with the flexibility to deliver the property fully or partially vacant depending on the buyer’s needs. This parcel also presents compelling long-term upside and re-development potential. Situated directly across from the Marsh Street Brownstones residential community, buyers are encouraged to explore zoning with the city for the potential future conversion of spaces into residential condos or luxury apartments.
