R. Zaballos & Sons

What R. Zaballos & Sons does

R. Zaballos & Sons, Inc. is a privately held, third-generation family-owned real estate developer, general contractor, and property management company headquartered in Hayward, California. Founded in 1932 as Zaballos Brothers Construction, the business has evolved into a diversified owner-operator of residential, commercial, medical/dental, and agricultural real estate across California, with operations concentrated in the San Francisco Bay Area (Hayward and San Jose) and Southern California (Aliso Viejo and San Clemente), plus 2,000-plus acres of vineyards in Northern San Joaquin County.

The company's portfolio includes the Walnut Hills and Ridgecrest residential apartment complexes in Hayward, the 90,000-square-foot Plaza Center Class A office and retail tower in Hayward anchored by tenants such as Safeway, Starbucks, Chase Bank, FedEx Office, and Quizno's, the 51,000-square-foot 3099 Orchard Drive single-tenant office in San Jose tenanted by Qorvo, and the adaptively reused 22425 Main Street property, which received a 2015 Historic Preservation Award from the Hayward Area Historical Society. The medical/dental segment consists of three Class A medical office buildings, with Aliso Viejo Medical Center anchored by Kaiser Permanente representing approximately 80% of that building's occupancy and 87% leased across five medical tenants.

Revenue is generated through recurring rental streams from residential, commercial, and medical tenants, supplemented by wine grape production from company-owned vineyards. The company leases directly to residential tenants through on-site leasing offices and to commercial and medical tenants through its corporate office and LoopNet listings. Capital allocation since the 1990s has emphasized diversification into agriculture and selective asset repositioning, rather than external acquisitions, new financing rounds, or rapid portfolio expansion. The current management team is led by the Zaballos family, including President/Partner Resti Zaballos Jr., alongside dedicated operations, finance, maintenance, and construction personnel.
