Local Roots

A Little Ontario History

Ontario was founded in 1882 by brothers George and William Chaffey, Canadian engineers who named their 'Model Colony' after their home province. They designed it around irrigation, citrus, and the grand Euclid Avenue — a wide, tree-lined boulevard that still runs through the heart of the city today.

The city incorporated in 1891. It is also home to the Graber Olive House, operating since 1894, and Ontario International Airport, which helped make the city a major logistics and business center for Southern California.

That history is why we build for the next hundred years. A Home City composite block home is designed to be the house your children and grandchildren still live in.

Historic Euclid Avenue in Ontario, California — **Historic Euclid Avenue** — Laid out by the city's founders as a grand tree-lined boulevard, Euclid Avenue is listed on the National Register of Historic Places.

Why Composite Block Makes Sense in San Bernardino County

Fast-growing new communities

Ontario Ranch and other new neighborhoods are adding thousands of homes. Faster structural schedules mean lower construction-loan interest and earlier move-in dates.

Seismic and wind resilience

The Inland Empire sits among several active fault systems and sees strong Santa Ana wind events. The system is IBC certified for seismic performance and rated for 275 mph winds.

Cost relief in a high-cost state

At $40.00 per square foot for structure, builders and families keep more of their budget for land, finishes and solar.
