Last updated on May 27th, 2024 at 06:30 am

Like a home, the city of Ontario was designed and remodeled for a purpose. At first, it was created to be a model agricultural community for citrus and vineyard cultivation. Today, Ontario is a transformed community—an industrial and manufacturing base in the economic heart of San Bernardino County.

But like any historical house, the present Ontario still has the elements from its past. It is still home to a few Victorian grove houses, mimicking the times of old Spanish dons. Additionally, most of the people living here still have Hispanic roots. By blending the old and the new, the city embraces new opportunities  and has been tagged as the “Southern California’s Next Urban Center.” 

The design reflects the purpose of your home, and our list shows ten of the best residential architects that can help you. We ranked them based on work history, recent projects, awards, and what clients think about them.
