This brief period was perhaps the greatest time of growth for Fullerton prior to the 1950s. The booming economy generated a demand for housing, and for the first time there was a market for exclusive neighborhoods. Not only was there a need for more housing but for residences of a more sophisticated type. Houses designed with Spanish Colonial and Cottage styles were built in response.

At the same time, concentrations of larger, more expensive residences appeared in several hillside subdivisions specifically promoted as high quality neighborhoods. Some of the Significant Properties of this period are the special housing in these areas.

Apartment developments, some built in a courtyard pattern, continued to be constructed to meet an evergrowing demand for housing.
