About

The CENTURY 21 system was founded in 1971 in Southern California. The founding principle was simple: to enable small independent brokers to operate under a common identity, sharing in the resources of collective advertising, training and marketing. This concept enabled brokers to remain responsive to the needs of their local marketplace while favorably positioning themselves against the competition. And it worked!

The CENTURY 21 network grew rapidly in the ’70s and ’80s, quickly becoming the largest real estate sales organization in the world. Sales topped the $70 billion mark. Independent polls now show the CENTURY 21 name to be the best-recognized name in real estate
