Ontario is a premier commercial and transportation nerve center of Southern California. Anchored by the fast-growing Ontario International Airport (ONT), the Ontario Convention Center, and the massive 8,200-acre Ontario Ranch master-planned development (one of California's largest master-planned residential communities), the local building market encompasses air cargo logistics, major commercial hospitality, light manufacturing, and thousands of single-family and multi-family homes. Contractors in Ontario require dependable, high-volume takeoff capabilities to bid successfully on logistics warehouses, airport facilities, and high-volume residential subdivisions.
