Local Roots

A Little Fontana History

Fontana grew out of citrus groves and poultry ranches in the early 1900s, and Route 66 — Foothill Boulevard — carried travelers right through town. In 1942, during World War II, Henry J. Kaiser built the Kaiser Steel mill here, the first integrated steel mill in the western United States, and Fontana became a true industrial city.

Fontana incorporated in 1952. Today it is one of the fastest-growing cities in the Inland Empire, with new neighborhoods stretching north toward the San Gabriel Mountain foothills and a strong logistics and industrial economy.

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 Route 66 (Foothill Boulevard) in Fontana, California — **Historic Route 66 (Foothill Boulevard)** — America's Mother Road runs straight through Fontana along Foothill Boulevard, lined with landmarks from the city's citrus and steel eras.

Why Composite Block Makes Sense in San Bernardino County

Santa Ana winds and wildfire

North Fontana borders the foothills, where Santa Ana wind events drive wildfire risk. Composite block contains zero wood and will not burn — a major advantage in the wildland-urban interface.

Earthquake country

Fontana sits between the San Andreas and San Jacinto fault systems. The composite block system is IBC certified for seismic performance.

Inland Empire housing demand

With California structural framing running near $95 per square foot, a $40.00 structural shell can be the difference between a project that pencils and one that doesn't.

Questions

Fontana Homeowners & Builders Ask

Can I build a composite block home in Fontana, CA?

Yes. California's building code is based on the International Building Code, and the composite block system is IBC certified, including for seismic performance. We provide the documentation package for City of Fontana permit submittals.

Is composite block fire resistant for Fontana's foothill neighborhoods?

Yes. The blocks are a non-combustible mineral composite with zero wood, so the structure does not add fuel to a fire — critical in Santa Ana wind and wildfire zones.

How much can I save building in Fontana?

The structural shell is $40.00 per square foot installed, compared with roughly $95 per square foot for conventional structural framing in California. On a 2,000 sq ft home that is a structural difference of about $110,000 before finishes.

Can I build an ADU in Fontana with composite block?

Yes. California's ADU laws make backyard units easier to permit statewide, and composite block is a fast, fire-resistant way to build one. We'll review your lot on a free Project Fit Call.

Is composite block earthquake safe?

The system is IBC certified for seismic performance and is lighter than concrete masonry, which reduces seismic loads. Specific seismic documentation is available on request.
