General Contractor in the Inland Empire

The Inland Empire is one of Southern California's fastest-growing regions, and Horizon Building Company is proud to serve clients across Riverside County and San Bernardino County. With rapid population growth driving demand for new housing, commercial space, and mixed-use development, the IE offers tremendous opportunity for developers and property owners alike.

Our team brings the same institutional-quality construction management and attention to detail that we deliver in Los Angeles to every Inland Empire project. We work in Riverside, Corona, Moreno Valley, Fontana, Ontario, Rancho Cucamonga, Upland, Claremont, Redlands, and throughout both counties. Whether you are building a ground-up multifamily community, renovating a commercial property, or developing a single-family subdivision, we manage the full construction lifecycle from permitting through certificate of occupancy.

As a California licensed contractor (CA License #01118216), we understand the local building departments, inspection processes, and code requirements specific to Inland Empire jurisdictions. Our established relationships with local subcontractors and suppliers ensure competitive pricing and reliable schedules for projects of all sizes.
