Southern California Builders

What Southern California Builders does

Southern California Builders is a family-owned general contracting firm founded in 1980 and headquartered in Westlake Village, California. The company operates as a full-service general contractor and construction project manager, executing ground-up builds, remodels, tenant improvements, design-build, and concrete tilt-up industrial construction. It serves a diversified client base spanning restaurant chains (Wood Ranch BBQ, Olive Garden, Buca di Beppo, McCormick & Schmick's), automotive retail (Keyes Motors), fitness (LA Fitness), self-storage (Extra Space Storage), senior living (Mount San Antonio Gardens), hospitality (Sheraton Universal Hotel), higher education (California Lutheran University), and nonprofit/institutional clients (Boy Scouts of America). The firm holds California Contractor License #404716, Nevada License #0086192, and Arizona License #ROC144077, and projects are concentrated across Ventura, Los Angeles, Orange, and San Diego counties.

Service scope covers the full construction lifecycle, beginning with pre-construction cost analysis, budget preparation, and design recommendations, and extending through project execution and closeout. Notable completed work includes the William Rolland Football Stadium at California Lutheran University, the Silver LEED-certified CLU Ullman Commons, the MSAG Green House (also Silver LEED), and the Boy Scouts of America headquarters — a national prototype design award winner. The firm has accumulated recognitions including an LA County Outstanding Performance Certificate, an AIA Design Excellence award, and a Best Sustainable Project award from the San Fernando Valley Business Journal.

The business operates on a project-based revenue model where pricing is determined per engagement by scope, size, and complexity. Business development relies primarily on direct client relationships, architect and developer referrals, repeat engagements, and the visibility of the completed-project portfolio rather than on formal sales channels or external capital. Gary Semolich serves as President and oversees day-to-day operations. The firm has remained independent and family-owned throughout its 45-year history, with no disclosed external investors, acquisitions, or major organizational changes.
