61,418-Square-Foot Office Property Offers Move-In Ready Headquarters or Strategic Redevelopment Opportunity in Mission Viejo
IRVINE, CA – June 18, 2026 – Stream Realty Partners, a national commercial real estate firm offering an integrated platform of services, has been selected to market the sale of 20532 El Toro, a three-story, 61,418-square-foot office property in Mission Viejo, California, formerly known as Mission Foothills Professional Building.
Situated in South Orange County with immediate access to the 241 Toll Road, the property offers strong connectivity to Irvine, Lake Forrest, Foothill Ranch, and the greater Southern California region—making it an active opportunity for owner-users, investors, and groups seeking repositioning or redevelopment.
Mission Foothills Professional Building features a striking open courtyard design that draws natural light throughout all three floors and fosters a collaborative atmosphere. Elevator service and flexible, move-in-ready suite configurations make the building well-suited for professional services firms, creative companies, and executive office users.
The property has undergone extensive renovations, featuring creative office finishes with open plenum ceilings, modernized restrooms, and collaborative kitchen areas, complemented by a new roof, HVAC systems, plumbing, and electrical throughout.
“20532 El Toro presents a compelling opportunity for a wide range of buyers in South Orange County,” said Mike Adams, Managing Director at Stream. “Currently configured for a full-building occupier, the property offers flexibility for a multi-tenant environment through the potential demising of six pods, creating the opportunity to generate tenant income. Additional use scenarios include condo conversion, medical-adjacent conversion, and long-term strategic land banking. Prior ownership capital investment reduces near-term execution risk for a future buyer. With creative office finishes, the potential for furniture to convey, and immediate regional accessibility, this property is well-suited for headquarters users, healthcare groups, nonprofits, and professional services firms seeking a move-in ready environment.”
