Irwindale was initially settled during the 1850s when it welcomed the families of Gregorio Fraijo and Fecundo Ayon from Mexico. The rocky foundation of this new settlement proved valuable as more and more people came to the region and demanded improved roads.

The first quarry opened in 1909, establishing the sand and gravel mining industry as a major player in the local economy. Today, nearly every highway in California, as well as many highways winding west of the Mississippi River, feature Irwindale rock as part of their foundation.
The fledgling little town chose to incorporate as a city on August 5, 1957, becoming the 56th city in Los Angeles County. This family-centered city is a magnet for commerce, currently housing more than 700 diverse businesses. Even with its transition as a first-class suburban city, Irwindale remains a close-knit community of 1,727 residents.
