The early 1920s were a time of rapid growth, both economically and physically for Fullerton. Post-World War I prosperity and the demands for housing by a population with greater expectations stimulated the expansion of the housing stock. It is to these years that the oldest neighborhoods in Fullerton date.

The construction of rental housing is another indication that Fullerton was evolving from an agricultural community to one having a more diverse economy.

The California bungalow – a simpler, less detailed version of its Craftsman ancestor – was the predominant type of house being built for modest income families, although a few small Spanish Colonial Revival houses were also constructed. Many of the city’s mature street trees were planted at this time, reflecting the heightened concern for landscaping that compliments the architecture of the community. The first real developers, in particular E. S. Gregory, were active at this time.

Much more diversity in style and design was found in housing for the wealthy. These are represented in the several grove and ranch houses scattered throughout the community.
